How do I get EDI-ready before my first retail purchase order?
Work backwards from the retailer’s routing guide. Confirm which transaction sets it requires and their deadlines, get GTINs assigned and a GS1 company prefix in place for SSCC labels, agree with your 3PL who builds the ASN from the pick data, and run test documents through certification before the first order lands.
The item that most often gets left late is the GS1 prefix, because it is administrative rather than technical. Without it there are no valid SSCCs, without SSCCs there are no compliant carton labels, and the first shipment cannot be received cleanly.
