What Retailers Expect from EDI (Before You Go Live)
Before you go live with any major retailer, there's a set of expectations you need to meet. Understanding them upfront can save you weeks of back-and-forth during onboarding.
Most suppliers focus on getting EDI set up. Fewer take the time to understand what retailers actually expect — before the first document is ever sent.
Knowing those expectations upfront can save you weeks of failed tests, revision cycles, and frustrating delays.
The basics: what every retailer expects
Correct document formats
Retailers don't accept "close enough." Every field, segment, and value in your EDI documents must match their specifications exactly. A missing field or incorrect date format can cause the entire document to fail validation.
Timely transmission
Documents need to arrive on time — not just eventually. ASNs (856) must be sent before the shipment arrives. Invoices (810) must follow within specific windows. Functional acknowledgments (997) should be near-immediate.
Reliable acknowledgment handling
Retailers expect you to send 997 acknowledgments when you receive their documents — and to process the 997s they send back. Missing acknowledgments are one of the most common fail points during compliance testing.
Consistent behavior across test cycles
Testing isn't just about one successful run. Retailers want consistent, error-free document exchange across multiple cycles. One good test followed by a failure won't get you approved.
Retailer-specific requirements to know
- Walmart: Strict ASN formatting, SSCC-18 labels, specific packaging hierarchy, AS2 required
- Target: Detailed compliance testing cycles, strict PO acknowledgment (855) rules
- Home Depot: AS2 required, precise invoice matching, fast 997 turnaround
- Amazon Vendor Central: Fast acknowledgment turnaround, accurate ASN timing
- Costco: Specific carton labeling standards, strict document sequencing
What retailers don't care about: Which EDI software or provider you use. How long your setup took. Whether you're a new or experienced supplier. They care about one thing: accurate, timely documents that match their specifications.
The most common reasons retailers reject EDI submissions
- Incorrect ASN packaging structure
- Missing required fields in any document
- Late document transmission
- Mismatched invoice and PO details
- Missing or incorrect 997 functional acknowledgments
How to meet retailer expectations from day one
The suppliers who go live fastest share a few common traits: they start with retailer-specific mappings (not generic EDI templates), they test thoroughly before submitting for certification, they have support available to fix issues immediately, and they don't cut corners during testing.
Final thoughts
Retailer expectations are clear — they just aren't always communicated clearly upfront. Understanding them before you start puts you in the best position to get approved quickly and stay compliant once you're live.
No onboarding fees. Pay only after you go live.
