In practice

Walmart EDI overview

Walmart EDI is the structured exchange of commercial documents between Walmart and businesses working in US retail, distribution-centre and drop-ship supply. The agreed document set starts with orders and invoices, with the operational emphasis on keeping order, fulfilment and finance data aligned.

A practical Walmart integration should connect the agreed document set with the systems that process it. XEDI maps the agreed ANSI X12 messages into ERP, warehouse, accounting or API workflows, while validation and alerts help teams deal with exceptions before they affect delivery or payment.

Every document validated before it moves

XEDI checks each Walmart order, despatch advice and invoice against the required format, so errors are caught before they reach your systems.

Onboarding

Walmart supplier onboarding process

For Walmart, onboarding starts with confirming the supplier relationship, document scope and connection route. XEDI then maps, tests and monitors the agreed workflow so teams can move from first order to stable live trading with clear ownership of exceptions.

02
Agree the Walmart order, response and invoice scope for the trading relationship.
03
Map Walmart message data to the supplier's ERP, warehouse, order-management and accounting systems.
04
Configure ANSI X12 validation, connection routing, exception alerts and user responsibilities in XEDI.
05
Complete the agreed Walmart test transactions, checking mandatory references, product data, delivery details and invoice matching.
06
Monitor initial live transactions and resolve rejected, delayed or mismatched documents with the operational and finance teams.
