Petco repositioned as a health and wellness company with vet services in store, and runs domestic and direct import vendors on different agreements. AS2 connection, 850, 856, 846 and 810. AIMS360 runs Petco alongside your other pet accounts from one pool of stock.
Petco repositioned itself as a health and wellness company with veterinary services inside its stores, which pulls pharmacy, prescription diets and supplements into the assortment beside the kibble. It also runs domestic and direct import vendors on different agreements, with import contracted through a wholly owned subsidiary. Two things a vendor setup has to get right before the first 850 arrives over AS2.
Petco EDI is the electronic document exchange Petco uses with its vendors. Published integration guidance describes an AS2 based routing guide, with the 850 purchase order, the 856 advance ship notice, the 846 inventory advice and the 810 invoice as the working set, and the 997 confirming receipt.
Petco issues its routing guide to vendors rather than publishing it openly, so what follows is drawn from trading partner directories, published integration guidance and one public SEC filing, presented as the shape of the program rather than as a specification to map from.
The document list is ordinary. What is not ordinary is the structure around it: a retailer that now describes itself as a health company, and a vendor program that treats direct import as a separate contract.
A Petco business agreement filed publicly as an SEC exhibit by an overseas pet products manufacturer shows the form carrying an agreement type field, in that instance IMPORT, with the counterparty being a wholly owned Petco import and distribution subsidiary rather than the retail company itself.
That is a concrete, checkable fact about how Petco structures its vendor base, and it means direct import is its own program. A domestic vendor setup does not extend to it automatically, the contracting entity is different, and the vendor and remit identifiers are assigned under that agreement.
For a brand manufacturing overseas and considering shipping direct to Petco rather than through your own warehouse, that is the first question to ask, before the EDI conversation starts. Which agreement, and which entity.
Petco's repositioning as a health and wellness company put veterinary care inside the retail footprint, which pulls prescription diets, pharmacy items and clinical supplements into the same building as toys and litter.
Food, treats, supplements and health products all carry a shelf life. Lot and date traceability is an operational requirement in that category whether or not any given retailer asks for the values on the ASN.
We have found no public Petco specification requiring lot codes and expiration dates on the 856, so this page does not assert one. AIMS360 carries lot, batch and expiration on inventory, so the data exists if Petco asks for it, and you still have it if Petco does not.
Petco, PetSmart, Chewy, Tractor Supply and Pet Supplies Plus are separate companies drawing on the same units in your warehouse. None reserves stock for the others. AIMS360 publishes each channel's availability from one available to sell number.

| Document | Direction | What it carries |
|---|---|---|
| 850 | Petco to you | Purchase order |
| 856 | You to Petco | Advance ship notice, matched to the carton and pallet marking on the freight |
| 846 | You to Petco | Inventory advice, what Petco can promise against |
| 810 | You to Petco | Invoice, matched to the purchase order and the ASN |
| 997 | Both ways | Confirms a document arrived and was structurally valid |
Published guidance describes the connection as AS2, meaning point to point over the internet with certificate based authentication and encryption, and no value added network in the middle. AIMS360 connects over AS2 natively.
AIMS360 is a consumer brands ERP with EDI built in-house and mapped to each retailer's own specification.
Petco orders import into the same platform holding your inventory, drawing on one pool with every other pet account.
The 846 reflects what you can genuinely ship across every channel rather than a Petco specific number.
Lot and expiration sit on the inventory record, so allocation works oldest first and the shipment knows which lot it carried.
Mobile scanning builds the shipment, the GS1-128 label prints and the 856 is generated from the same scanned units over AS2.
The 810 comes off the same shipment, so quantity and price agree with the 850 and the 856. Any deduction that still arrives is logged against the original order.
EDI is part of the platform, with no per document, per transaction or kilocharacter charges on our side as volume grows.
Petco is one of 350+ retailer connections on AIMS360, alongside PetSmart, Chewy, Tractor Supply and Pet Supplies Plus, all drawing on one pool of stock.
Commonly published across trading partner directories: the 850 purchase order, the 856 advance ship notice, the 846 inventory advice and the 810 invoice, with the 997 functional acknowledgment confirming receipt. Petco publishes an AS2 based routing guide to its vendors rather than openly, so confirm the set issued to your account before mapping.
No. A Petco business agreement filed publicly as an SEC exhibit by an overseas vendor shows the agreement carrying a type field, in that case IMPORT, and the counterparty being a wholly owned Petco import and distribution subsidiary rather than the retail entity. Direct import is a distinct program with its own paperwork, and a domestic vendor setup does not automatically extend to it.
Published integration guidance describes Petco's routing guide as AS2 based, meaning documents move point to point over the internet with certificate based authentication and encryption. AIMS360 connects over AS2 natively, so there is no separate translator or value added network sitting between the ERP and Petco.
Petco repositioned itself as a health and wellness company with veterinary services inside its stores, which widens the assortment into pharmacy, prescription diets, supplements and wellness products. Those are consumables with lot and date sensitivity and, in some cases, regulatory handling. A brand selling into that side of the store is managing traceability, not just replenishment.
We have not found a public Petco specification stating it, so we are not going to claim one. What is true regardless is that pet food, treats, supplements and health products are consumables, and lot and date traceability is an operational requirement whether or not a retailer asks for the values in a file. AIMS360 carries lot and batch numbers and expiration dates on inventory, so the data exists if Petco asks for it.
Yes, and most pet brands do. They are separate companies with separate programs, but they draw on the same physical units in your warehouse and none of them reserves stock for the others. AIMS360 holds one available to sell pool and publishes derived positions to each channel, so the number Petco sees is the same number every other account is drawing down against.
Petco's vendor onboarding runs through its own supplier process and business agreement, with vendor and remit identifiers assigned on approval. EDI onboarding follows a buyer relationship rather than preceding it. Nothing on this page is a route to a buyer; it describes what you need to be ready for once one exists.
Yes. AIMS360 EDI is built in-house and mapped to each retailer's own specification, connecting over AS2, so Petco orders land against live inventory, availability publishes from one pool, and the ASN is built from the units the warehouse scanned. Lot and expiration data carries through on consumables. Petco is one of 350+ retailer connections, with no per document, per transaction or kilocharacter fees on our side. See the full retailer list.
Last reviewed 1 September 2026 by the AIMS360 EDI team. Petco issues its routing guide to vendors rather than publishing it openly, so the document set and connection method described here are drawn from third party EDI trading partner directories and published integration guidance. The domestic and import agreement distinction is drawn from a publicly filed SEC exhibit, which is not recent, so confirm the current entity structure with your Petco contact. No public Petco source states a lot code or expiration date requirement on the ASN, and this page does not claim one. Petco and all other names referenced are trademarks of their respective owners, and AIMS360 is not affiliated with or endorsed by Petco Health and Wellness Company, Inc.
