What is EDI? Transaction codes, costs and ERP integration for apparel brands
EDI is how retailers send you orders and how you send back ship notices and invoices, system to system, with no email and no retyping. This guide explains what EDI stands for, how EDI software and your ERP fit together, every transaction code apparel retailers use, what EDI really costs once the usage fees are counted, and how brands become EDI compliant without adding headcount.
What is EDI (electronic data interchange)?
EDI, electronic data interchange, is the computer to computer exchange of business documents, such as purchase orders, ship notices and invoices, in a standard electronic format between trading partners. A retailer's system sends the order straight into yours, and yours sends the shipment notice and invoice straight back. No email, no PDF, no retyping.
Whether you are evaluating electronic data interchange for the first time or refining an existing setup, you will find the specific EDI documents, trading-partner requirements, pricing models, and automation workflows that matter most in apparel, plus a side-by-side comparison of standalone EDI, third-party EDI providers, and built-in ERP EDI. AIMS360 is purpose-built apparel software with EDI native to the platform, built on 40+ years in fashion, 350+ retailer EDI integrations, and more than $2.5 billion in transactions processed annually, so where it is relevant we explain how that approach compares.
What Does EDI Stand For?
EDI stands for Electronic Data Interchange, the computer-to-computer exchange of business documents in a standardized electronic format between trading partners, replacing paper, faxes, email, and manual data entry.
Instead of emailing spreadsheets or rekeying orders by hand, EDI transmits structured information directly between business systems automatically. The term electronic data interchange refers to the technology standard itself, not a single product. EDI defines how documents are structured and transmitted; EDI software is the platform that creates, translates, sends, and receives those documents inside your operations.
In practice, when a retailer like Nordstrom places a purchase order, EDI delivers that order straight into your system, ready for fulfillment with no typing and no missing fields. The same automation applies to invoices, shipping notices, inventory updates, and payment remittances.
EDI uses standardized formats, most commonly ANSI X12 in North America and EDIFACT internationally, so any two EDI-capable systems can communicate regardless of their internal differences. That standardization is what makes electronic data interchange the common language of B2B commerce across retail, manufacturing, logistics, and healthcare.
Key characteristics of EDI
- Standardized formats: documents follow strict structural rules (segments, elements, qualifiers) so systems parse them automatically.
- Computer-to-computer: no human intervention is needed for routine EDI transactions.
- Trading-partner specific: each EDI retailer layers its own requirements on top of the base standard.
- Secure transmission: data travels over secure channels, a VAN (Value Added Network) or AS2 direct connection.
Why EDI Matters in the Apparel & Fashion Industry
EDI matters in apparel because retailers require exact data formats and tight timing. Small errors lead to delays, chargebacks, or lost accounts. EDI moves orders, shipments, and payments automatically and accurately between a brand and its retail partners, which is why being EDI capable is a prerequisite for selling to nearly every major retailer.
For apparel brands specifically, electronic data interchange handles the complexity unique to fashion EDI: style-color-size grids, carton-level packing detail, UPC barcodes, and retailer-specific routing. Done well, it produces measurable results.
Key benefits of EDI for apparel brands
- Speed: orders and invoices move instantly, not days later by email or mail.
- Accuracy: eliminates the manual-entry errors that cause chargebacks and compliance failures.
- Retailer compliance: meets each retailer's trading rules and EDI format requirements automatically.
- Scalability: handles hundreds of EDI retailers, styles, and SKUs without adding headcount.
- Faster payments: automated invoices and payment remittances accelerate cash flow.
- Fewer chargebacks: validated ASNs and UCC-128 labels reduce costly penalties.
Done well, the return is concrete: brands on an integrated apparel ERP typically save 10 to 20-plus hours a week of manual work and cut chargebacks dramatically once ASNs, labels, and compliance checks are automated from a single source of data. But before any of that, most brands ask a more basic question, do you even need EDI in the first place?
Do You Need EDI? Why Retailers Require You to Be EDI Compliant
If you want to sell to a major retailer, you almost certainly have to be EDI compliant, if you are not, the retailer will not buy from you. Large retailers require every document (orders, shipments, invoices) to be exchanged electronically with no paper, and they hand each vendor an EDI routing guide of exact rules you must follow.
Here is the plain-English version. A large retailer processes millions of orders, and its systems are fully automated. One brand emailing PDF purchase orders or faxing invoices would break that automation, so retailers do not allow it. To become an approved vendor you have to prove you can send and receive every required transaction electronically and successfully: the purchase order (850) comes in, you send back an acknowledgment (855), you ship with a compliant advance ship notice (856) and label, and you bill with an 810 invoice, all automatically, with no paper.
Being EDI capable (you can trade electronically) is step one. Being EDI compliant (you do it exactly the way that retailer demands) is what keeps the account. To make sure you get it right, every retailer gives you an EDI routing guide, the rulebook for that specific relationship, and usually requires you to pass a certification test before your first live order. Brands selling to Nordstrom EDI, Wayfair EDI, Kohl's EDI, Burlington EDI, and other major retailers all go through this. The right apparel ERP software handles the routing-guide rules for you, so compliance is automatic instead of a manual project for every account.
What Is an EDI Routing Guide?
An EDI routing guide (also called a vendor compliance guide or implementation guide) is the detailed rulebook a retailer gives every vendor. It spells out exactly which EDI documents to send, how to label and pack each carton, which carriers to use and when to ship, and the chargeback penalties for getting it wrong.
The routing guide is the single source of truth for doing business with that retailer. Miss a rule in it and you receive a chargeback, a deduction taken straight out of your payment, often 2 to 3 percent of the invoice value. Because every retailer's guide is different, Nordstrom's rules are not Macy's rules, keeping up with all of them across many accounts is exactly what EDI software is built to automate.
What's inside an EDI routing guide
- EDI & technical requirements: the required transaction sets (850, 855, 856, 810, 997, and more), the EDI version (such as ANSI X12 4010 or 5010), the communication method (VAN or AS2), your trading-partner IDs and qualifiers, and the testing and certification steps before go-live.
- Item & product data: UPC / GTIN requirements, vendor item numbers, case packs, units of measure, pricing, dimensions, and NRF color and size codes, often registered in a retailer catalog before your first PO is even accepted.
- Labeling: exact UCC-128 / GS1-128 carton label specifications and placement, the SSCC-18 serial code, plus price and UPC tickets, hang tags, RFID, and retail-ready presentation.
- Packing: carton and pallet weight and size limits, case-pack and pre-pack assortment configuration, pack-by-store vs. bulk rules, polybagging, folding, and protective packaging.
- Routing & logistics: approved carrier lists, transportation mode, freight terms (collect vs. prepaid), how to request routing via the 753 and receive instructions via the 754, delivery-appointment scheduling, and 'do not ship before / cancel' dates.
- ASN rules: when the 856 advance ship notice must be transmitted (usually before the truck leaves your dock), its hierarchical structure, and the rule that every SSCC-18 label must match the ASN exactly.
- Invoicing & payment: 810 invoice timing, the three-way match against the PO and receiving report, payment terms, allowances, and remit-to details.
- Shipping documents: the VICS Bill of Lading and, for imported goods, customs documentation.
- Compliance & chargeback schedule: the exact penalty fees for each violation, a late or inaccurate ASN, the wrong label, a carton over or under weight, shipping early or late, or missing documents.
No brand should have to memorize a dozen routing guides by hand. AIMS360 Apparel ERP stores each retailer's routing-guide rules in its mapping engine and validates every document against them before it is sent, and AIMS360's experts in EDI on staff handle routing-guide setup, mapping, and certification so you reach go-live faster.
What Is EDI Software?
EDI software is the technology that creates, translates, transmits, receives, and processes EDI documents. It converts your internal data into standardized EDI formats such as ANSI X12, routes documents to trading partners, and turns inbound documents back into records your business can use.
Put simply, the meaning of EDI software is this: it is what makes a business EDI capable. It handles four jobs: translation (mapping your data to and from EDI formats), transmission (sending and receiving via VAN or AS2), validation (checking documents against trading-partner rules), and processing (turning an inbound purchase order into something your team can act on). The question 'is EDI a software?' comes up often, and the precise answer is that EDI is a standard, while EDI software is the application that implements it.
What EDI software is used for in apparel is concrete: receiving purchase orders, acknowledging them, generating compliant advance ship notices and carton labels, sending invoices, syncing inventory for dropship, and reconciling payments, all without manual re-entry. The difference between EDI tools is how much of that they actually do. A standalone translator only converts files; an ERP with built-in apparel EDI runs the entire order-to-cash cycle in one system.
EDI translator vs. EDI mapping software vs. full EDI software
These three terms get used interchangeably, but they are not the same thing, and the difference is exactly what trips up brands shopping for EDI. EDI translation software (an EDI translator) is the narrow piece that converts a file between your internal format and a standard such as ANSI X12. EDI mapping software is the configuration layer that defines how each field maps from your data to a specific trading partner's exact spec. Full EDI software includes both translation and mapping, but it also handles transmission, compliance validation, and the actual business processing, turning an inbound order into a pick ticket, an invoice, and a shipment. A standalone translator or mapper makes you EDI capable on paper; only a complete system, ideally built into your apparel ERP, makes you compliant and hands-free in practice.
What Is EDI in ERP? EDI vs. ERP Explained
EDI in ERP means Electronic Data Interchange capabilities built into an Enterprise Resource Planning system. EDI and ERP are not the same: ERP runs your core operations (orders, inventory, accounting), while EDI is the standardized way you exchange documents with trading partners. They work best when EDI is native to the ERP.
Think of it this way: your ERP is the brain that processes and manages business data; EDI is the nervous system that carries data between your brain and the outside world, retailers, 3PLs, and carriers. You need both, and they perform best when connected.
EDI vs. ERP: the difference
- ERP (Enterprise Resource Planning) manages core operations: orders, inventory, production, accounting, and shipping.
- EDI (Electronic Data Interchange) is the standardized communication layer for exchanging documents with trading partners, purchase orders, invoices, ASNs, and inventory feeds.
When a retailer asks 'Is your ERP integrated with your EDI provider?', they want to know whether your order system and your EDI system are connected, meaning EDI purchase orders flow into your ERP as sales orders, and documents like ASNs and invoices generate from your ERP data without re-entry.
With AIMS360 Apparel ERP, the answer is yes by default, because EDI is built directly into the ERP, there is no separate EDI provider to integrate. For growing mid-market brands running 5 to 50-plus retail partners, that matters: disconnected systems create data lag, sync errors, and compliance failures, while built-in EDI in ERP keeps every transaction in the same platform that already manages products, inventory, orders, and shipping. That single-platform EDI ERP software approach is what removes the middleware most brands never needed.
EDI provider alone vs. an ERP with built-in EDI
This is the distinction that decides how much manual work your team lives with every day. A standalone EDI provider only moves documents, it receives the 850 and sends your 856 and 810, but it has no idea what is in stock, what is in production, or which order to fill first. Everything downstream, keying the order, allocating inventory, planning production, packing, and invoicing, still happens in separate systems or by hand.
An apparel ERP with native EDI closes that loop. Because production management, order processing, inventory management, and allocation live in the same platform as the EDI engine, and the EDI is built in, not a bolted-on third party, an inbound EDI purchase order flows straight into live inventory, allocates against open production, and generates the ASN, label, and invoice from the same data. The benefits compound:
- One source of truth: the order, the inventory, the allocation, and the EDI documents all read from the same records, so the ASN always matches what physically ships.
- No sync lag or sync errors: there is no scheduled hand-off between an ERP and a separate EDI provider that can fall out of step and create compliance failures.
- Smarter allocation: EDI orders are allocated against real, live inventory and open production, not a stale snapshot, which is what prevents overselling on dropship.
- Production tied to demand: incoming EDI order volume can feed cut tickets and purchasing, so you make what retailers are actually buying.
- One vendor, one support team: when something breaks there is no finger-pointing between your ERP and a third-party EDI provider, one team owns the whole flow.
How EDI Works: The EDI System & Process Flow
An EDI transaction follows six steps: a business event creates a document, EDI software maps it into a standard format, it is transmitted via VAN or AS2, the receiver translates and processes it, a 997 functional acknowledgment confirms receipt, and a business response (acknowledgment, shipment, or invoice) follows.
The EDI process flow
A business event triggers a document, for example, a retailer creates a purchase order.
The data is translated into a standard EDI format via EDI mapping, converting internal fields to EDI segments and elements.
The document is sent to the trading partner through a VAN or by EDI direct connect over AS2.
The receiving system accepts the file, translates it into its own format, and processes the transaction.
The receiver returns an EDI 997 confirming the file arrived and is syntactically valid.
The partner acts, sends an 855 acknowledgment, ships goods with an 856 ASN, and sends an 810 invoice.
EDI direct connect vs. VAN
There are two ways to transmit EDI transactions. A VAN (Value Added Network) works like a postal service for EDI: your documents go to the VAN, which routes them to the right trading partner. EDI direct connect, usually over the AS2 protocol, is a point-to-point link between you and a specific partner with no VAN in between. Many larger retailers offer or require direct connections, so the strongest EDI systems support both VAN and AS2 natively.
The Complete List of EDI Transaction Codes & Documents
Fashion retailers use specific EDI transaction codes, the 850 (purchase order), 855 (acknowledgment), 856 (ASN), 810 (invoice), 846 (inventory), 820 (payment), and 997 (functional acknowledgment) are the core set, with routing, change, and warehouse documents layered on as operations grow.
Each code (also called a transaction set) represents one type of business document. These EDI transaction types, the different types of EDI documents, group into core retail, logistics, warehouse, and financial sets. The table below is a complete apparel and supply-chain reference; tap any code to see how AIMS360 supports it.

How much does EDI software cost?
It depends on the model, and the headline price is the smallest part of it. With an ERP that has no built-in EDI you pay two vendors: the ERP vendor charges to integrate its system with a third-party EDI provider such as SPS Commerce or TrueCommerce, often per retailer, and then the provider charges roughly $250 to $500 per month per trading partner, plus per-document, kilocharacter or per-line fees on top. Some ERPs that do have their own EDI module still meter it by document, kilocharacter and line. AIMS360 charges one flat monthly fee per retailer, with unlimited transactions and no document, kilocharacter, line or VAN fees.
The honest answer to how much does EDI software cost is that the model you choose drives the total far more than any single line item. There are four, and only one of them stops growing when your order volume does.
Low upfront cost, often per-document or per-partner pricing. The hidden cost is labor: every order is downloaded and rekeyed by hand, and manual ASNs are where chargebacks come from.
Two bills. The ERP vendor charges to connect its system to the EDI provider, often per retailer, plus mapping and setup. The provider then charges about $250 to $500 per month per trading partner, plus per-document, kilocharacter or per-line fees. Two systems to keep in sync, two support queues.
One vendor, but the per-document, kilocharacter and per-line fees stay on the invoice, so the bill climbs with volume. Your busiest, most profitable months are also the most expensive months to send documents.
One flat monthly fee per retailer with unlimited transactions. No VAN fees, no kilocharacter fees, no per-document fees, no per-line fees. Mapping, trading partner setup and certification are handled by the in-house EDI team; implementation is a one-time engagement, not a monthly meter.
EDI fees explained: VAN, kilocharacter, per-document, per-line, connection and mapping
Two EDI quotes can look almost identical and cost wildly different amounts in practice, because the real expense lives in the stack of usage fees beneath the headline. Here is what each one means and why it matters as you grow:
- VAN fees: a value added network (VAN) is the private network that routes EDI documents between you and your trading partners. VANs charge a recurring mailbox or connection fee plus usage, so the more you trade, the more you pay.
- Kilocharacter (KC) fees: the classic VAN usage charge, billed per 1,000 characters transmitted. A detailed 856 ASN full of carton and item data burns far more kilocharacters than a small order.
- Per-document fees: a charge for every EDI document you send or receive, each 850, 856, 810 and so on. Your bill rises in lockstep with order count.
- Per-line fees: a charge for every line item inside a document. A purchase order with 200 styles costs far more than one with five, so per-line pricing punishes exactly the large orders you want to win.
- ERP integration and connection fees: what the ERP vendor charges to link its system to the EDI provider, and what the provider charges to connect each new trading partner. Often per retailer, so growing your account list gets expensive fast.
- Mapping fees: professional services charges to build or change the EDI map for a retailer's exact spec, billed again every time you add a partner or a retailer updates its routing guide.
Illustrative comparison. Metered EDI, whether it is a third-party provider on top of your ERP or an in-house module that still charges per document, kilocharacter and line, rises with your order and transaction volume. AIMS360 stays at one flat monthly fee per retailer. The shaded area is what you overpay as you grow.
And what about free EDI software? Free and open-source EDI translators exist, and they will convert a file, but they do not manage trading partner connections, compliance validation, labeling, or your orders and inventory. For an apparel brand selling to major retailers, free EDI tools rarely meet retailer compliance rules, and the chargebacks and manual labor usually cost far more than the tool ever saved. That is why growing brands compare paid EDI solutions on total cost of ownership rather than headline price, especially when shopping for EDI software for small business, where staff time is the scarcest resource. For plans and add-ons, see AIMS360 pricing.
EDI Software for Apparel & Small Fashion Businesses
The best EDI software for apparel understands fashion-specific data, style-color-size grids, pre-packs, UPCs, carton labeling, and dropship compliance, and connects directly to retailer requirements. For small and growing brands, an apparel ERP with built-in EDI removes the need for separate middleware and scales as you add retailers.
Generic EDI tools treat apparel like any other industry. They have no concept of a size run, a pre-pack, or a carton-level pack-by-store requirement, so the work of making data retailer-correct falls back on your team. Purpose-built EDI software for apparel handles those structures natively, which is why edi asset software for apparel companies and cloud software for apparel with EDI and accounting are common searches, brands want one system that speaks fashion and retail at the same time.
For a small business, the trap is bolting a generic EDI provider onto a generic ERP and discovering that neither understands apparel. Fashion ERP software with EDI built in avoids that: orders arrive correctly, labels and ASNs are generated from the same packing data, and you add retailers by configuring a profile rather than buying another integration. That is the most reliable path to becoming EDI capable without adding headcount.
Comparing EDI Approaches: Standalone vs. Third-Party vs. Built-In ERP EDI
There are three EDI models: a standalone portal (manual, cheapest upfront, scales poorly), an ERP plus a third-party EDI provider (more automated but two systems to sync and pay for), and built-in ERP EDI (one system, one vendor, no middleware). The right choice depends on how many retailers you serve and how much manual work you can absorb.
Standalone EDI platform: you use a separate web portal to receive and send EDI documents, then manually re-enter orders and upload ASNs and invoices. It is cheap to start and gets you EDI capable for one retailer quickly, but every step is manual, error rates are high, and it does not scale.
ERP plus a third-party EDI provider (middleware): a provider such as SPS Commerce or TrueCommerce sits between your ERP and your retailers. It is more automated than a portal, but you are running two systems that must stay in sync, you pay for both, setup runs two to four weeks per partner, and the provider is industry-agnostic, it does not understand apparel workflows.
ERP with built-in EDI: AIMS360 Apparel ERP takes a different approach, EDI is built into the ERP, so there is no middleware, no separate portal, and no third-party provider fee. Your ERP is your EDI system, and every step from order to label to invoice happens in one place. For an apparel brand this is what makes built-in EDI the best EDI software setup in practice: it is cloud-based, purpose-built for fashion, and priced as one predictable subscription.
| Capability | Standalone EDI Portal | ERP + Third-Party EDI | Built-In ERP EDIRecommended |
|---|---|---|---|
| Order import (850) | Manual download & re-entry | Automated, sync between 2 systems | Fully automatic as sales orders |
| ASN generation (856) | Manual creation in portal | Needs data sync from ERP | Auto-generated from packing data |
| Invoice automation (810) | Manual upload | Automated with sync delay | Instant, triggers at shipment |
| Inventory feeds (846) | Manual export / upload | Scheduled sync, may lag | Real-time from live inventory |
| UCC-128 / GS1-128 labels | Separate label software | Separate tool or manual config | Generated from packing data |
| VICS Bill of Lading | Not included | Often manual | Built-in, auto-generated |
| Chargeback management | No tracking | Basic, separate from ERP | Built-in tracking & prevention |
| Apparel-specific workflows | None, generic EDI | Industry-agnostic | Built for style-color-size |
| Compliance validation | None | After transmission | Before transmission, at source |
| Systems to manage | 2+ (portal + tools) | 2 (ERP + provider) | 1, everything in AIMS360 |
| Monthly cost structure | Per-transaction / per-partner | ERP integration fee plus $250 to $500 per month per partner, plus document, kilocharacter or line fees | One flat fee per retailer, unlimited transactions, no VAN, KC, document or line fees |
| New retailer setup | Days to weeks | 2 to 4 weeks both sides | Days, no middleware |
| When something breaks | You troubleshoot alone | 2 vendors point fingers | One team, one call |
| Best for | 1 to 2 retailers, no ERP | Generic ERPs without native EDI | Apparel brands at any scale |
EDI Service Providers: What They Do (and Don't)
An EDI service provider offers EDI translation and transmission as a standalone service, converting data to EDI format and routing it via VAN or AS2. Providers move documents, but they do not manage your inventory, orders, shipping, labels, or chargeback compliance, which is why they are used alongside a separate ERP.
The most commonly used EDI service providers, the EDI software companies most brands evaluate, in apparel and retail include SPS Commerce, OpenText (formerly GXS / Liaison), TrueCommerce, Cleo, B2BGateway, and Orderful. They are competent at the technical transmission of EDI documents. What they are not is a business management system, and that distinction is where apparel brands get into trouble.
What EDI service providers don't do
- No inventory management: they can transmit an 846 feed but have no idea what is actually in your warehouse.
- No order management: they deliver an 850 but cannot allocate inventory, create pick tickets, or run fulfillment.
- No shipping or label generation: they do not pack cartons, generate UCC-128 labels, or create VICS BOLs.
- No compliance validation at source: they send what you give them. If your ASN data is wrong, the wrong data goes to the retailer.
- No chargeback management: when a penalty arrives, you reconcile it across two disconnected systems.
The bottom line: an EDI service provider is a communication pipe. It moves data from A to B, but it does not know what the data means or what to do when something goes wrong on the business side. AIMS360 Apparel EDI removes that gap by combining the communication layer and the business-management layer in one system, orders, inventory, shipping, labels, EDI, accounting, and compliance in one place, with one support team.
What Is an EDI Expert?
An EDI expert is a specialist who manages a brand's entire EDI relationship, interpreting each retailer's routing guide, configuring and mapping the EDI software, running certification testing, and monitoring live transactions from the first purchase order through to the invoice. The core goal of an EDI expert is to keep every document compliant so the brand avoids chargebacks.
EDI looks simple until a retailer rejects an ASN overnight or changes its routing guide without warning. An experienced EDI expert, sometimes called an EDI specialist or EDI consultant, is the person who keeps those problems from turning into deductions. They know how to read a routing guide, build the map to a retailer's exact spec, pass certification, and interpret a 997 or a rejection to fix an issue before it becomes a chargeback.
What an EDI expert handles end to end:
- Routing-guide interpretation: turning a retailer's compliance guide into the exact rules your system enforces.
- Mapping & setup: configuring each transaction (850, 855, 856, 810, and more) to that partner's precise specification.
- Certification & testing: getting you approved and live with each new retailer.
- Go-live & monitoring: watching transactions daily, catching rejects and missing 997s, and resolving issues fast.
- Chargeback prevention: the through-line of all of it, keeping documents accurate and on time so penalties never hit your account.
This is exactly where most standalone EDI providers leave a gap: they hand you software or a transmission pipe, not a person who owns your compliance. AIMS360 has EDI experts on staff, apparel-EDI specialists who handle routing guides, mapping, certification, and go-live for you, so you are not learning ANSI X12 the hard way while chargebacks pile up.
What Does It Mean to Be EDI Compliant?
Being EDI compliant means you exchange EDI documents correctly, meeting every trading partner's specific data rules, timing windows, and formats. Being EDI capable means you can send and receive EDI; being EDI compliant means you do it without errors. Failing compliance results in retailer chargebacks.
In apparel, compliance is contractual, not optional. Every major retailer publishes a vendor compliance guide (a routing guide or trading-partner agreement) specifying exactly how each EDI document must be formatted, what data it must contain, and when it must be sent. Miss those requirements and you receive chargebacks, penalties that cost apparel brands thousands of dollars a year.
Key requirements for EDI compliance
- Accurate ASNs (856): the advance ship notice must match the physical shipment exactly, every carton, item, and quantity. Mismatches are the number-one cause of chargebacks.
- Correct UCC-128 labels: each carton needs a compliant barcode with an SSCC-18 code that matches the ASN.
- On-time PO acknowledgments (855): often required within 24 to 48 hours.
- Timely invoices (810): transmitted within the retailer's window, often same-day.
- Real-time inventory feeds (846): accurate and frequent for dropship to avoid overselling.
- Retailer-specific data: each EDI retailer has unique fields and qualifiers, Nordstrom differs from Macy's, which differs from Amazon.
The structural way to stay compliant is to generate every document from the same data and validate before transmission, not after. With AIMS360 EDI software, the ASN always matches the shipment, the label always matches the ASN, and the invoice always matches the PO, because there is only one source of data, and unlike standalone providers that only tell you a document failed after the fact, validation happens before anything is sent.
Bulk vs. Dropship EDI Orders Explained
Bulk orders are large-quantity purchases shipped to a retailer's stores or distribution centers. Dropship orders are individual consumer orders you fulfill directly to the shopper on the retailer's behalf. Both arrive by EDI but follow different fulfillment workflows.
Bulk orders are the traditional B2B wholesale model and remain the highest-volume order type for most apparel brands. Macy's might send an 850 for 1,000 units across colors and sizes; Burlington might order 5,000 for store distribution. The cycle is: import the PO with full style-color-size detail, reserve inventory by grid, create picking and packing documents with compliant UCC-128 labels, then auto-generate the 856 ASN, 810 invoice, and VICS BOL after shipping.
Dropship orders (also called drop ship EDI) are single-consumer orders sent directly from your warehouse to the end customer. When a shopper buys on Nordstrom.com, Wayfair, or Amazon, that EDI order routes to you via electronic data interchange. The workflow imports each consumer order via the 850, syncs real-time availability via the 846, generates a shipping label with the retailer's branding, returns tracking via the 856, and posts an automated 810 invoice. Combined with inventory management and shipping, the dropship cycle runs end to end inside one system.
EDI Retailers: Who Requires EDI in Fashion?
Virtually every major retailer requires vendors to be EDI capable. If you sell wholesale or dropship to department stores, specialty chains, or marketplaces, you must exchange EDI with them. Major apparel EDI retailers include Nordstrom, Macy's, Amazon, Wayfair, Kohl's, Burlington, Dillard's, and 350-plus more.
The retailer-specific work is where compliance details bite, and it is also where most brands first encounter EDI. Common apparel EDI trading partners include:
- Nordstrom & Nordstrom Rack EDI, bulk and dropship
- Macy's / Bloomingdale's, bulk and dropship
- Amazon, dropship and FBA
- Wayfair EDI, dropship
- Kohl's EDI, bulk and dropship
- Burlington EDI, bulk
- Dillard's, bulk (Dillard's EDI)
- Saks Fifth Avenue, Neiman Marcus, bulk and dropship
- TJ Maxx / Marshalls, Target, Anthropologie, Urban Outfitters, Revolve, and 350-plus more
See the complete, always-growing list at AIMS360 EDI retailer integrations. Supply chain EDI also extends up the chain: brands exchange planning and shipping schedules (the 830 and 862) with factories, and warehouse documents (the 940, 943, and 944) with third-party logistics providers.
How to Get Started with EDI: A Step-by-Step Roadmap
To get EDI capable: choose an apparel ERP with built-in EDI, set up your VAN or AS2 connection and trading-partner profiles, connect each retailer, map and test every required transaction, automate the workflow, then monitor for errors and missing 997s.
Pick an apparel ERP with built-in EDI integration rather than bolting on third-party middleware.
Your ERP vendor sets up VAN or AS2 connections, configures trading-partner profiles, and obtains required qualifiers.
With 350-plus retailers pre-supported, most are already configured.
Validate every required document (850, 855, 856, 810, 846, 997, and so on) with each retailer.
Let the ERP handle imports, acknowledgments, packing, shipping, labeling, and invoicing.
Review EDI dashboards for errors, rejected transactions, and missing 997 acknowledgments.

Frequently asked questions about EDI in apparel
EDI stands for Electronic Data Interchange. It is the computer-to-computer exchange of business documents, such as purchase orders and invoices, in a standardized electronic format between trading partners, replacing paper, email, and manual data entry.
EDI software is the technology that creates, translates, sends, receives, and processes EDI documents within a business. It converts internal data into standardized EDI formats such as ANSI X12, transmits documents to trading partners, and turns inbound documents back into usable records.
EDI software is used to automate the exchange of business documents with trading partners: receiving purchase orders, sending order acknowledgments, generating advance ship notices, transmitting invoices, syncing inventory feeds, and reconciling payments, all without manual re-entry.
EDI itself is a standard, not a piece of software. EDI defines how business documents are structured and transmitted. EDI software is the application that implements that standard, creating, translating, and exchanging the documents within your business systems.
EDI in ERP refers to Electronic Data Interchange capabilities built into an Enterprise Resource Planning system. When EDI is native to the ERP, purchase orders import automatically as sales orders, invoices generate from shipments, and ASNs are created from packing data, with no middleware or manual file transfers.
No. ERP manages core business operations such as orders, inventory, production, and accounting. EDI is the standardized method for exchanging documents between trading partners. They are complementary, and the most efficient setup is when EDI is built directly into the ERP.
It depends on the model. With an ERP that has no built-in EDI you pay twice: an integration fee to connect the ERP to a third-party EDI provider, often per retailer, and then roughly 250 to 500 dollars per month per trading partner to the provider, plus per-document, kilocharacter or per-line fees. Some ERPs with their own EDI module still meter documents, kilocharacters and lines. AIMS360 charges one flat monthly fee per retailer with unlimited transactions and no document, kilocharacter, line or VAN fees; implementation is a one-time engagement.
Free and open-source EDI tools exist, but they only translate files. They do not manage trading-partner connections, compliance validation, labeling, or your orders and inventory. For apparel brands selling to major retailers, free EDI tools rarely meet retailer compliance requirements and usually cost more in chargebacks and labor than they save.
Being EDI capable means your business has the technology and processes to send and receive EDI transactions electronically. This typically requires EDI software, a VAN or AS2 connection, and active trading-partner agreements. Most major retailers require vendors to be EDI capable.
Being EDI compliant means you exchange EDI documents correctly according to each trading partner's specific rules, data requirements, timing windows, and formats. It goes beyond being EDI capable. Failing compliance, such as an inaccurate ASN or a missing label, results in retailer chargebacks.
An EDI trading partner is any business you exchange EDI documents with. In apparel that includes retailers such as Nordstrom, Macy's, and Amazon, as well as third-party logistics warehouses, freight carriers, and factoring companies.
EDI mapping is the process of translating data fields between your system's internal format and the standardized EDI format that trading partners require. Mapping defines how your order, item, and shipment data is converted into EDI segments and elements, and back again.
The most common are the EDI 850 Purchase Order, 855 PO Acknowledgment, 856 Advance Ship Notice, 810 Invoice, 846 Inventory Advice, 820 Payment, 860 PO Change, 753 and 754 Routing, 852 Product Activity, 870 Order Status, and 997 Functional Acknowledgment.
Bulk orders are large-quantity purchases shipped to a retailer's stores or distribution centers. Dropship orders are individual consumer orders you fulfill directly to the end customer on the retailer's behalf. Both use EDI but follow different fulfillment workflows.
EDI chargebacks are financial penalties retailers issue for compliance failures, most often an advance ship notice or label that does not match the physical shipment. The most reliable way to avoid them is to generate every document from one source of data and validate it before transmission.
Built-in EDI means EDI processing lives natively inside your ERP, with no middleware. A third-party EDI provider is a separate service that sits between your ERP and your retailers, requiring data to sync between two systems. Built-in EDI removes the sync layer, the separate fees, and the second support queue.
An EDI service provider offers EDI translation and transmission as a standalone service, handling document routing through a VAN or AS2. Providers move data, but they do not manage your inventory, orders, shipping, labels, or chargeback compliance, so they are typically used alongside a separate ERP.
A UCC-128 label, also called a GS1-128 label, is a standardized carton shipping label required by most major retailers. It carries an SSCC-18 serial shipping container code that must match the data in the EDI 856 advance ship notice.
An EDI expert is a specialist who manages a brand's EDI from routing-guide setup and mapping through certification, go-live, and daily monitoring. The goal is to keep every document compliant and prevent retailer chargebacks. AIMS360 has apparel-EDI experts on staff.
A VAN (value added network) fee is the recurring charge to use the network that routes EDI documents between trading partners. Kilocharacter fees are usage charges billed per 1,000 characters transmitted, so larger documents and higher volume cost more. Many providers also add per-document and per-line fees, and some ERPs with in-house EDI still meter the same way. AIMS360 charges none of these: one flat fee per retailer with unlimited transactions.
