Chewy lists Infocon Systems as a Preferred EDI Provider. That recognition reflects more than three decades of managed EDI experience and a track record of connecting suppliers to Chewy accurately, quickly, and without in-house EDI resources. For pet food, treat, supply, and pharmacy brands, it means there is a fully managed path to Chewy compliance that Chewy itself points vendors toward.
Chewy is one of the largest pet retailers in North America, and it runs its supplier relationships on a traditional vendor model: Chewy issues purchase orders, vendors ship to Chewy fulfillment centers, and Chewy sells to the consumer. Every step of that cycle is driven by EDI. Vendors that want to sell to Chewy must exchange orders, acknowledgments, shipment notices, and invoices electronically and pass Chewy's EDI testing before the first live purchase order arrives.
This guide covers what Chewy requires, the EDI transaction sets involved, the compliance details that matter most, and how Infocon Systems handles all of it as a managed service.
What Chewy Requires From EDI Vendors
Chewy's EDI requirements are similar in shape to those of major brick-and-mortar retailers such as Target and Kroger, with a few characteristics specific to a high-velocity e-commerce fulfillment network:
- EDI is mandatory. Chewy purchase orders are issued via EDI, and invoices are expected via EDI. Vendors are onboarded through Chewy's partner portal and complete EDI testing before going live.
- Frequent, fulfillment-center-specific purchase orders. Chewy replenishes multiple fulfillment centers across the United States, so vendors receive a steady flow of orders that must be routed and shipped to the correct location.
- Timely purchase order acknowledgments. Chewy relies on the EDI 855 to confirm what will ship, when, and in what quantity, so its inventory planning stays accurate.
- ASN and label accuracy. The EDI 856 Advance Ship Notice must match the physical shipment carton for carton, with GS1-128 labels that scan to the ASN data at the receiving dock.
- Invoice-to-PO matching. The EDI 810 must reconcile to the original purchase order and ship notice for clean, prompt payment.
Because Infocon Systems maintains current Chewy specifications as a Preferred EDI Provider, vendors do not need to interpret these requirements themselves. Infocon Systems builds the maps, applies Chewy's rules, and validates every transaction before it transmits.
Chewy EDI Transaction Sets
These are the ANSI X12 transactions most Chewy vendors exchange. Infocon Systems supports every one of them, plus any additional document Chewy introduces for a specific program.
Purchase Order
Chewy sends the 850 to order product for a specific fulfillment center. It includes item identifiers, quantities, pricing, requested ship and delivery dates, and Chewy's internal vendor number. Infocon Systems delivers each 850 directly into your ERP or order system.
Purchase Order Acknowledgment
Confirms to Chewy which lines will ship as ordered and flags any quantity or date changes. Accurate, timely 855s keep Chewy's replenishment planning aligned with what you can actually deliver.
Advance Ship Notice
Details the shipment hierarchy: shipment, order, pack, and item levels, along with carrier, tracking, and carton serial numbers. The 856 must match the GS1-128 labels on each carton so Chewy can receive by scan.
Invoice
The electronic invoice that initiates Chewy's payment cycle. Infocon Systems generates the 810 from your ERP invoice data and validates that it reconciles to the 850 and 856 before transmission.
Functional Acknowledgment
Confirms receipt of each inbound and outbound document. Infocon Systems monitors 997s continuously and resolves any rejected or missing acknowledgment before it affects order flow.
Purchase Order Change
Used when Chewy needs to modify quantities, dates, or items on an open purchase order. Infocon Systems applies 860 changes to the original order in your ERP so downstream documents stay in sync.
Inventory Inquiry / Advice
Where Chewy requests inventory visibility, the 846 shares available-to-promise quantities so Chewy can plan orders around your actual stock position.
Chewy EDI Compliance Essentials
Meeting Chewy's specifications is about data accuracy and consistency across every document in the order cycle. These are the areas Infocon Systems manages most closely for Chewy vendors:
GS1-128 Shipping Labels
Every carton shipped to Chewy carries a GS1-128 label with a serialized SSCC that ties back to the 856. Infocon Systems generates compliant labels from ASN data so the barcode, the carton, and the electronic record always agree.
ASN Accuracy and Timing
The 856 must transmit before the shipment arrives and reflect exactly what was packed. Infocon Systems validates hierarchy, quantities, and identifiers against the original 850 before the ASN leaves your system.
Acknowledgment Windows
Chewy expects the 855 within its defined window after the 850 is issued. Infocon Systems automates acknowledgment generation from your order data so confirmations go out on time, every time.
Invoice Reconciliation
Item numbers, unit costs, quantities, and PO references on the 810 are checked against the purchase order and ship notice so Chewy's accounts payable can match and pay without exceptions.
Fulfillment Center Routing
Each 850 specifies the Chewy fulfillment center it is destined for. Infocon Systems maps ship-to locations correctly into your ERP and WMS so orders are picked, labeled, and routed to the right facility.
Why Chewy Vendors Choose Infocon Systems
Chewy's Preferred EDI Provider designation signals that Infocon Systems already understands Chewy's specifications, testing process, and label requirements. For vendors, that translates into a few practical advantages:
Fully Managed, End to End
Infocon Systems handles mapping, testing, certification, monitoring, and every specification update Chewy issues. There is no software to install and no internal EDI expertise required. When Chewy changes a requirement, Infocon Systems updates the map and re-validates before it affects your orders.
Preferred Provider Status Across the Pet and Retail Landscape
Chewy is one of many retailers that list Infocon Systems as a Preferred EDI Provider, alongside Target, Kroger, Albertsons, Tractor Supply, Home Depot, Dollar General, Publix, and others. Pet brands that sell through multiple channels can run every trading partner through a single managed connection.
1,000+ Trading Partner Connections
Infocon Systems maintains active EDI connections with more than 1,000 trading partners. Adding Chewy to an existing Infocon Systems account, or adding Tractor Supply, Petco, or a distributor after Chewy, is a configuration step rather than a new project.
Chewy EDI Integrated With Your ERP
EDI does not require an ERP integration to function, but most Chewy vendors want purchase orders landing directly in their business system and invoices generated from it automatically. Infocon Systems integrates Chewy EDI with any ERP platform, including:
Chewy 850s flow into your ERP as sales orders. The 855, 856, and 810 are generated from your order, shipment, and invoice records with no re-keying. Infocon Systems uses REST APIs as the primary integration method, with SOAP available where a platform requires it, and builds and maintains the integration on your behalf.

EDI for Pet Brands and Suppliers
Chewy vendors span pet food and treats, supplements, litter, toys, beds, apparel, aquatics, and pet pharmacy products. Many also sell through Tractor Supply, PetSmart, Petco, Walmart, Amazon, and regional grocers. Infocon Systems supports the full set of pet retail trading partners, so a single managed EDI relationship covers Chewy today and every additional channel as the brand grows.
For consumable categories, Infocon Systems also handles lot, date, and case-pack data in the 856 and 810 where Chewy or other partners require it, keeping product traceability consistent across the supply chain.
