Petco EDI Vendor Requirements: The Complete 2026 Guide
Everything pet brands need to know about selling to Petco via EDI — documents, compliance, and setup
Petco operates more than 1,500 stores and has pivoted hard toward becoming a full-service pet health and wellness company. Their vendor program covers food, treats, toys, accessories, and health and wellness SKUs, and the EDI requirements reflect that breadth. If you are selling into Petco, you will be running EDI from day one.
This guide walks through everything brands need to know.
Required EDI Documents
Petco uses standard ANSI X12 EDI across DC and ecommerce flows.
| Document | Name | Purpose |
|---|---|---|
| 850 | Purchase Order | Petco sends the order |
| 855 | PO Acknowledgment | You confirm line status |
| 856 | Advance Ship Notice | Carton and pack details |
| 810 | Invoice | Matches PO and ASN |
| 997 | Functional Acknowledgment | Technical receipt |
| 846 | Inventory Advice | Required for drop-ship programs |
| 860 | PO Change | Petco modifies an existing PO |
Vendor Requirements
Petco tracks vendors on:
- On-time delivery to DC
- ASN accuracy and timeliness
- Fill rate
- GS1-128 carton label performance
- Invoice match rate
- Drop-ship order fulfillment SLA
Chargebacks and Risk
Petco chargebacks commonly include:
- Late ASN
- Missed ship window
- Carton label failures
- Short ship without notice
- Invoice cost mismatch
- Drop-ship SLA violations
Where Brands Struggle
Health and wellness compliance
Petco's wellness program has additional requirements around ingredient reporting, expiration codes, and lot traceability. Skipping these fields in your ASN triggers rejection.
Dual DC and drop-ship flows
Petco runs both DC replenishment and drop-ship ecommerce. These are two different EDI setups. New vendors frequently build for DC and get surprised when drop-ship POs start arriving.
Inventory feed frequency
For drop-ship, Petco expects frequent 846 updates — often multiple times per day for fast-moving SKUs. Weekly feeds are not enough.
