Critical Chargeback & Import Pitfalls We Prevent
Common EDI mistakes that trigger $250+ retailer fines or accounting balance errors
Sending BAK02=AD When Short-Shipping a Line Item
Risk: OTIF In-Full PenaltyConfirming 100% acceptance in the 855 and then shipping only 80% on the 856 ASN triggers a severe unannounced short-ship fine.
Mismatched Product Qualifiers Between 850 and 855
Risk: 824 RejectionReturning only your Vendor SKU (VN) when the buyer sent an ASIN (BP) or DPCI (IN) causes line-matching failure.
Late 855 Acknowledgment Transmission
Risk: PO Auto-CancellationAmazon Vendor Central and Target require 855 acknowledgments within 24 hours of 850 PO receipt.

Frequently Asked Technical Questions
ANSI X12 specification details, retail companion rules, and ERP import answers
What is the difference between EDI 997 and EDI 855?
An EDI 997 Functional Acknowledgment only confirms that the X12 file was received and passed syntax checks. An EDI 855 Purchase Order Acknowledgment confirms business acceptance of the items, prices, and delivery dates.
Does Walmart require an EDI 855?
Walmart Domestic Warehouse orders typically skip the 855 and go straight from 850 to 856 ASN, whereas Walmart Dropship (DSV), Target, and Amazon Vendor Central mandate an 855 within 24 hours.
