Overview
Walmart is the most demanding compliance environment in retail. Suppliers face strict, continuously evolving requirements spanning EDI document exchange (850, 855, 856, 810), advance ship notice accuracy down to the carton level, OTIF performance thresholds that directly affect scorecards and future order allocation, packaging and labeling specifications, and audit readiness across every distribution channel.
The consequences of non-compliance are immediate and measurable: chargebacks for late or inaccurate ASNs, reduced order volume for poor OTIF scores, and potential program suspension for repeated failures. Most suppliers discover compliance gaps reactively — after the chargeback has already been issued.
APIWORX automates the Walmart compliance lifecycle end-to-end. Purchase orders are ingested and acknowledged within SLA windows automatically. ASNs are generated directly from warehouse shipment events with validated carton content, weight, and SSCC data. Invoices are matched against PO line items and shipment records before submission, catching discrepancies before Walmart does. OTIF performance is monitored continuously with exception alerting when metrics approach threshold boundaries.
The platform also manages Must Arrive By Date (MABD) tracking, appointment scheduling coordination, routing guide compliance for carrier selection, and SQEP (Supplier Quality Excellence Program) documentation workflows.
Best suited for consumer goods brands, food and beverage manufacturers, health and beauty suppliers, and distributors selling into Walmart stores, Walmart.com, or Walmart Marketplace.
