Native Ross Stores EDI inside AIMS360: 850 in, 856 and 810 out, 860, 865, 812 and 864 where used, the Ross and dd's SKU cross referenced, pallets loaded by PO and style, and no drop ship, because Ross sells nothing online.
Ross Stores EDI Integration
AIMS360 is a consumer brands ERP with Ross Stores EDI built in, for Ross Dress for Less and dd's DISCOUNTS. One platform runs your inventory by style, color and size and produces every document Ross asks for: 850 orders in, carton markings and labels with the Ross SKU, 856 ASNs and 810 invoices out, the 860, 865, 812 and 864 where your buyer uses them, and 997s both ways. Closeouts, packaways and upfront buys into eight DCs from one stock record, with no drop ship program to pretend about. The connection is managed by our EDI team.
What system manages inventory and does EDI with Ross Stores? AIMS360. It runs your inventory and your Ross EDI in one platform: native maps for the 850, 856, 810 and 997, plus the 860, 865, 812 and 864 where your buyer uses them, the Ross and dd's SKU held as a cross reference so it prints on the carton markings, pallets built by purchase order and style with the placard and the packing list on the last pallet, and the ASN and invoice produced off the same shipment record. Ross has no ecommerce site, so there is no drop ship program, no 846 feed and no marketplace, and every order ships to one of eight distribution centers. Ross publishes no EDI network mandate, so AIMS360 connects directly or through the VAN you already use. You do not pair AIMS360 with SPS Commerce, TrueCommerce or another EDI provider.
Ross EDI Documents
Built from the same ERP records that run your inventory, warehouse and accounting, so the carton markings, the placard, the ASN and the invoice describe the same pallet.
| Transaction | What it does for Ross |
|---|---|
| EDI 850 purchase order | Ross transmits the order and AIMS360 imports it as a sales order validated against your catalog at the UPC level, with the DC read off the order and the Ross or dd's SKU number cross referenced to your style. An off price 850 is usually a one time buy, a closeout, a packaway or an upfront order, so there is no replenishment stream behind it and the order you get is the order you ship. |
| EDI 856 ship notice (ASN) | Carton level notice of what is on the pallet, sent at shipment close. Ross pallets are loaded by purchase order and style and the packing list rides on the last pallet, so the ASN has to describe cartons the way they were actually stacked. AIMS360 builds it from the shipment your warehouse closed. |
| EDI 810 invoice | One per PO, sent after the ASN. AIMS360 produces it off the same shipment record, which is the whole point on a program where Ross does not publish its deduction rules. |
| EDI 860 purchase order change | Reported by one Ross EDI provider along with the 865 acknowledgment. AIMS360 applies the change to the open order and sends the 865 from the order record where your buyer uses it. |
| EDI 812 credit and debit adjustment | Reported by one provider as part of the Ross set. AIMS360 posts it against the invoice so accounting sees the reason before the remittance arrives. |
| EDI 864 text message | Reported by one provider. The free text notice Ross uses for exceptions. AIMS360 logs it against the trading partner so it does not sit unread. |
| EDI 997 acknowledgment | Both directions on every document. AIMS360 generates the outbound 997 on receipt. |
| GS1-128 carton label | Reported by EDI providers as required on every Ross carton. Ross's own packaging documents, as summarized by a compliance vendor, spell out carton markings and pallet placards rather than an SSCC rule, so the label spec is confirmed in testing. AIMS360 prints the Ross label and the carton markings from the same shipment record as the ASN. |
Vendor Requirements
Ross keeps its Vendor Compliance Manual, its routing guides and its packaging standards behind the Ross Partners portal, and its EDI specifications are not public at all. The rules below come from what Ross publishes on its corporate site and in its filings, from a compliance vendor's summary of the Ross shipping and carton marking guidelines dated late 2024, from the 2015 Ross shoe vendor manual, and from EDI provider pages. The figures say which is which. Confirm every number in the portal before you plan a shipment around it.
| Requirement | What Ross expects, as reported |
|---|---|
| Vendor portal | Ross Partners at partners.rossstores.com, with access by Ross Supplier ID, supplier name and Ross buyer contact through the merchandise supplier mailbox. The Vendor Compliance Manual, the Ross domestic routing guide amended September 2024, the dd's domestic routing guide dated October 2024, the April 2024 retail packaging standards, the November 2024 shoe packaging guide and the October 2024 CPSIA vendor documentation manual all live there. |
| EDI network | Ross does not publish a VAN mandate or an X12 version. EDI providers that trade with Ross consistently list the 850, 856, 810 and 997, and one provider adds the 860, 865, 812, 864 and 855. No provider lists an 852 or a 753 and 754 pair, which fits a buyer that places one time orders and routes freight through its own portal. |
| Routing | Freight routing runs through Ross's transportation portal at transportation.ros.com, described by a 3PL as the system for carrier assignment, pickup scheduling and delivery coordination, rather than through EDI. Collect and prepaid terms, lead times and the appointment process are in the routing guide behind the login. |
| Cartons | Conveyable cartons from 15 by 15 by 6 inches to 29.5 by 24 by 24 inches, from 10 to 50 pounds, fragile cartons capped at 35. Markings: PO number, quantity, vendor style number, color, size, item description, the Ross or dd's SKU number and pack counts. Nested inner cartons or polybags are allowed in a carton and must be pre ticketed. Shoes, per the 2015 manual, one SKU per carton in double wall 48 ECT board, musical runs of 4 to 12 pairs. |
| Pallets | 48 by 40 standard, no taller than 6 feet including the pallet and 5 feet for heavy product, loaded by purchase order and style, SKUs not mixed on a pallet unless the count is too small to avoid it. A pallet placard of at least 8.5 by 11 inches on two sides in 35 point type with the PO, vendor style, carton count and units per carton. Pallets numbered 1 of, 2 of. Double stacking only on a framed wood or solid top pallet. |
| Packing list and BOL | A packing list with carton quantities and styles by pallet on the last pallet, and the bill of lading attached to a pallet. Ross's routing guide lists the BOL rules by banner. |
| Pre ticketing | Ross runs a pre ticket vendor control program, and the shoe manual requires vendor pre ticketing through Fineline Technologies. Retail price tickets, hangers and floor ready rules for apparel are in the April 2024 packaging standards behind the portal. |
| Distribution centers | Eight in operation per the fiscal 2025 annual report: Perris, Moreno Valley and Shafter in California; Buckeye, Arizona, opened May 2025; Brookshire, Texas; Fort Mill and Rock Hill in South Carolina; and Carlisle, Pennsylvania. A ninth in Randleman, North Carolina is finishing construction, and Ross announced a tenth in Bakersfield, California on September 23, 2026 for 2032. Ross and dd's share the network. |
| Chargebacks | Not published. Ross's expense offset schedule, fill rate expectations and dispute window are in the Vendor Compliance Manual behind the portal. Public sources only say what Ross does not do: it does not sell online, so there is no drop ship deduction to worry about either. |
| Drop ship | None. Ross has no ecommerce site. Its own FAQ says merchandise cannot be purchased online because the opportunistic and changing nature of its merchandise does not lend itself to selling over the internet, and its annual report describes the business as exclusively brick and mortar. There is no 846 and no consumer packing slip. |

Ross EDI Workflow
One loop, one system, and one chance to get the pallet right.
| Step | What happens |
|---|---|
| 1. Order arrives | The 850 lands and becomes a sales order validated at the UPC level, with the DC read off the order and the Ross or dd's SKU cross referenced to your style. A closeout or packaway buy is usually the whole order in one 850, so allocation runs against all of it. |
| 2. Acknowledge | The 997 goes back on receipt. If your buyer uses the 855 or the 860 and 865, they go back from the order record. |
| 3. Routing | The shipment is entered in the Ross transportation portal and routed as the guide for your banner says, collect or prepaid, with the appointment set against the DC. |
| 4. Pick, pack, ship | The built-in warehouse module packs to the Ross carton limits, one SKU per carton for shoes, nested packs pre ticketed, and prints the carton markings and the label from the shipment record. |
| 5. Pallet | Built on a 48 by 40 to 6 feet, loaded by PO and style, SKUs not mixed, with the placard on two sides, the pallets numbered, and the packing list on the last one. |
| 6. ASN | The 856 transmits at shipment close, carton by carton, describing the pallets the way they were built. |
| 7. Invoice | The 810 goes out after the ASN, one per PO, matching the shipment. |
| 8. Adjustments | An 812 or 864 comes back if Ross deducts or flags an exception, and AIMS360 posts it against the invoice so the dispute starts from the same record. |
Native vs Bolted On
Short answer, no. Ross publishes no network mandate, and an off price order does not come around twice.
The carton markings, the placard, the ASN and the invoice come off one shipment record, and the Ross or dd's SKU lives once as a cross reference. On a one time closeout order there is no second chance to fix the pallet, so the ASN has to be right the first time.
Our EDI team runs the connection, the testing and the maps. Ross publishes no network mandate, so you do not need one.
Put an EDI network in front of an ERP with no native EDI and the ASN is only as accurate as the pallet somebody retyped into it, on a program where Ross does not publish the deduction schedule you would be arguing against.
And an off price order is often the last order for that style, so a deduction is not a cost of doing business, it is the margin on the deal.
Ross Programs
Four ways a Ross purchase order can happen, and the company behind them.
The core of off price. Ross buys manufacturer and brand overruns and canceled orders during and at the end of a season, and in August 2026 its CEO said the closeout opportunities are very strong with a lot of goods being canceled. The PO is a one time buy, often large, into one of eight DCs. AIMS360 allocates the whole order and ships it complete.
Product Ross buys to store and release later, sometimes for the beginning of the same selling season next year. Packaway was 36 to 37 percent of Ross inventory through 2026. The goods sit in a Ross warehouse for months, so tickets, cartons and pallets have to hold up in storage, and the ASN is the record Ross receives against long before the goods hit a store.
Production direct from brands and factories, planned rather than opportunistic. Same documents, a firmer calendar, and the same DC rules. Ross has said more than half of what it sells originates in China, so tariff timing sits underneath every upfront calendar.
Ross's second banner, 376 stores as of August 2026, with its own domestic routing guide dated October 2024 and its own international guide, sharing the DC network and the Ross Partners portal. Carton markings call for a Ross or dd's SKU number, so the banner is set on the trading partner in AIMS360 and the right guide governs the shipment.
One thing to keep straight: Ross Stores, Inc. is listed on NASDAQ as ROST, headquartered in Dublin, California, run by Jim Conroy as CEO since February 2025, and reported fiscal 2025 sales of $22.8 billion with a plan for about 115 new stores in 2026. It sells nothing online. A brand that arrives expecting a drop ship program or an 846 feed has the wrong retailer.
One Stock Record
A Ross order is a one time buy that has to ship complete into one DC, built by PO and style, so the useful number is not what you have in total, it is what you can commit to one closeout order and still cover the retailers that reorder.
| Situation | What AIMS360 does |
|---|---|
| Loaded by PO and style, SKUs not mixed | Packing rules hold the Ross constraints, so a pallet is built by PO and style, the placard and the ASN describe it the way it was stacked, and the packing list on the last pallet matches both. |
| A closeout that has to ship complete | Allocation runs against the whole PO at the size level before the shipment is released, so a one time order goes out complete or the buyer hears about it before the truck is booked. |
| Closeout and replenishment on one pool | The units you commit to a Ross closeout come out of the same stock record that feeds your replenishment retailers, so a packaway buy does not sell inventory a department store PO already owns. |
| Eight DCs, two banners | The DC cross reference and the banner live once in AIMS360, so the carton markings, the ASN and the invoice carry the same destination and the same SKU number without anyone retyping it. |
| A 3PL holding stock | Integrated 3PL locations feed the same record, so the carton count on the routing entry is real and the ASN describes cartons that exist. |
| Selling the other off price chains | The same pool feeds Ross, Burlington, TJ Maxx and Marshalls, Nordstrom Rack and the rest without a separate inventory file per retailer. Each is its own trading partner with its own rules. |
Managed Onboarding
Our EDI team builds the connection and tests it with Ross. You supply the Ross Supplier ID, the Ross Partners login for the compliance manual and the routing guides, the transportation portal login, and the buyer's PO instructions.
| Stage | What we do |
|---|---|
| Before kickoff | Pull the current Vendor Compliance Manual, the routing guide for your banner and the packaging standards from Ross Partners, confirm collect or prepaid, and confirm which DC the first PO ships to. |
| Setup | Build the customer account with the Ross and dd's SKU cross reference, the DC list, packing rules to the Ross carton limits, the carton markings and label, the placard, FOB and carrier SCACs. Ross publishes no network mandate, so the connection is direct or through the VAN you already use. |
| Tickets | Set up the pre ticket program with the buyer, because Ross expects vendor pre ticketing and nested packs ticketed before they arrive. |
| Label proof | Get the carton markings, the label and the pallet placard approved against the packaging standards before the first shipment. |
| Testing | Test the 850, 856, 810 and 997 end to end with Ross, plus the 860, 865, 812 and 864 if your buyer uses them, including a pallet loaded by PO and style with the packing list on the last pallet. |
| Go live | Watch the first PO from the routing entry to the appointment, the ASN and the invoice, then read the first remittance with you for deductions. |
| After | Track guide revisions in Ross Partners. Ross amended its domestic routing guide in September 2024 and its packaging standards in April 2024, and publishes no changelog. |
We keep emergency EDI support running around the clock, because a closeout appointment at a Ross DC does not move because your ASN did not go.
Ross EDI FAQ
No drop ship, the document set, the eight DCs, the pallet rules, packaway, and what Ross keeps behind the portal.
AIMS360. It is a consumer brands ERP with Ross EDI built in: the 850 purchase order in, the 856 ship notice and 810 invoice out, 997s both directions, and the 860, 865, 812 and 864 where your buyer uses them, with the Ross or dd's SKU cross referenced to your style and the carton markings, placard and ASN printed from one shipment record. Inventory, warehouse and EDI are one system. Our own EDI team runs the connection.
No. Ross sells nothing online. Its own FAQ says merchandise cannot be purchased online because the opportunistic and changing nature of its merchandise does not lend itself to selling over the internet, and its annual report describes the business as exclusively brick and mortar. There is no 846 feed, no marketplace and no consumer packing slip. Every Ross order ships to a distribution center.
Ross does not publish its EDI specification. EDI providers that trade with Ross consistently list the 850 purchase order, 856 ship notice, 810 invoice and 997 acknowledgment, and one provider adds the 860 change, 865 change acknowledgment, 812 adjustment, 864 text message and 855. No provider lists an 852 or a 753 and 754 pair. The mapping guides are behind the Ross Partners portal.
Ross publishes no VAN or provider mandate, and no SPS Commerce partner page for Ross exists. AIMS360 connects to Ross directly or through the VAN you already use, and our EDI team runs the maps.
Eight in operation per the fiscal 2025 annual report: Perris, Moreno Valley and Shafter, California; Buckeye, Arizona, opened May 2025; Brookshire, Texas; Fort Mill and Rock Hill, South Carolina; and Carlisle, Pennsylvania. Randleman, North Carolina is finishing construction, and a Bakersfield, California center was announced September 23, 2026 for 2032. Ross Dress for Less and dd's DISCOUNTS share the network.
As reported from the Ross shipping guidelines of November 2024: conveyable cartons from 15 by 15 by 6 to 29.5 by 24 by 24 inches and 10 to 50 pounds, fragile cartons at 35 pounds or less. Pallets 48 by 40, no taller than 6 feet including the pallet, loaded by purchase order and style with SKUs not mixed unless unavoidable, a placard of at least 8.5 by 11 inches on two sides, pallets numbered, and the packing list on the last pallet.
PO number, quantity, vendor style number, color, size, item description, the Ross or dd's SKU number and pack counts, with supplier and shipper information added on import orders. Shoes ship one SKU per carton in double wall 48 ECT board with musical runs of 4 to 12 pairs. EDI providers report a GS1-128 label on every carton; Ross's own packaging documents, as summarized, spell out markings rather than an SSCC rule, so the label is confirmed in testing.
Through the Ross transportation portal at transportation.ros.com, which a 3PL describes as the system for carrier assignment, pickup scheduling and delivery coordination. Ross Dress for Less and dd's DISCOUNTS have separate domestic routing guides, amended September 2024 and October 2024, behind the Ross Partners login. Collect and prepaid terms, lead times and appointments are in those guides.
Merchandise Ross buys with the intent to store it and release it later, which may be the beginning of the same selling season the following year, typically for less than six months. Packaway was 36 to 37 percent of Ross inventory through 2026. The PO ships to a Ross DC like any other order, and the goods have to survive storage, so tickets, cartons and pallets matter more than usual.
Ross does not publish a chargeback or expense offset schedule, a fill rate threshold or a dispute window. Those terms are in the Vendor Compliance Manual behind the Ross Partners portal. AIMS360 keeps the ASN, the label data and the invoice on one shipment record, which is the documentation a dispute needs.
2,328 as of August 1, 2026: 1,952 Ross Dress for Less stores and 376 dd's DISCOUNTS stores, with a plan for about 115 new stores in fiscal 2026. Ross Stores, Inc. is listed on NASDAQ as ROST, headquartered in Dublin, California, run by CEO Jim Conroy since February 2025, and reported fiscal 2025 sales of $22.8 billion.
Through the buying offices in New York and Los Angeles rather than a public application. Once a buyer places an order you get a Ross Supplier ID and access to the Ross Partners portal, which holds the Vendor Compliance Manual, the routing guides, the packaging standards and the CPSIA documentation manual. AIMS360 takes it from the vendor number.
Ross runs a pre ticket vendor control program, its shoe manual requires vendor pre ticketing through Fineline Technologies, and its shipping guidelines say nested packs must be pre ticketed. The apparel ticket, hanger and floor ready rules are in the April 2024 packaging standards behind the portal.
We do. The maps belong to us, so a revision is our work rather than a project for your team. Ross amended its domestic routing guide in September 2024, its dd's guide in October 2024 and its packaging standards in April 2024, all behind the portal, so we check them with you before every season.
See AIMS360 allocate a closeout PO, build the pallet by PO and style, print the placard and send the ASN and invoice from one record.
