EDI Requirements

Electronic Data Interchange (EDI) is the process that enables companies to exchange business information electronically.  Using standardized formats, documents including Purchase Orders, Advanced Ship Notices and Invoices can be transmitted electronically without human intervention.  Companies that exchange documents electronically are called trading partners.

Drop Ship Suppliers

Suppliers who are doing Drop Ship business will need to work directly with the Drop Ship Team to become compliant.  This is a different program and process than partners whose merchandise will be sold in stores.  Drop Ship Requirements


Benefits of EDI


EDI Flow Process

The steps for basic EDI are as follows:

• NMG transmits a purchase order (850) to the Supplier.  The Supplier sends a return transmission (997 Functional Acknowledgement) to NMG confirming receipt of the purchase order.

• The Supplier packs the merchandise and attaches a GS1-128 shipping label to the individual carton.  This label provides information regarding the contents of the carton.

• The 856 ASN transaction must be transmitted at the time of shipment release from the Supplier's facility.  The ASN is the electronic notice indicating what product is being shipped for a specific purchase order/store.  ASNs are considered late if not received same day of shipment release.  Violations will be assessed for non-compliance.  

• The final step is the Supplier’s transmission of the electronic Invoice (810), which is sent to the NMG for payment.
