What is EDI Supplier Compliance?

TL;DR

EDI supplier compliance is the discipline of meeting a retailer's exact EDI specifications — document formats, timing windows, label and ASN accuracy, routing — so a supplier avoids chargebacks and stays in good standing on retailer scorecards.

Definition

EDI supplier compliance covers the EDI documents (POs, ASNs, invoices, inventory feeds, routing instructions), the formatting (X12, EDIFACT, retailer-specific extensions), and the operational rules (timing windows, label accuracy, packaging standards) that retailers require from their suppliers.

Common documents

850 (purchase order), 855 (PO acknowledgement), 856 (advance ship notice), 810 (invoice), 846 (inventory inquiry), 860 (PO change), and 940/945 (warehouse shipping).

Why it matters

Retailers like Wayfair, Walmart, Amazon Vendor, Target, and Costco issue chargebacks for late ASNs, mislabeled cartons, missing fields, and timing violations. Chargebacks are routinely 1–5% of invoice value and add up fast.
