Overview

Understanding Dollar General integration

Who this is for: Consumer goods, food and general merchandise vendors supplying Dollar General distribution centers.

Dollar General operates a large network of small-format stores supplied through distribution centers, and it relies on EDI for ordering and invoicing with vendors. Third-party sources agree that the purchase order and invoice are central, with functional acknowledgments confirming receipt. Sources differ on whether ship notices and purchase order acknowledgments are required for every vendor, which suggests requirements vary by program.

Invoice discipline is a recurring theme. Sources describe Dollar General expecting an invoice for each purchase order, invoices that cover a single shipment against a single order, and payment that depends on matching the purchase order, the distribution center receipt and the invoice. Invoices that combine shipments or orders can be rejected.

Dollar General publishes vendor resources through its vendor portal. Vendors should confirm their document set, connection method and testing requirements there before going live.
