What is Walmart Drop Ship EDI?

Definition

Walmart Drop Ship EDI is the electronic data interchange framework used by Walmart.com drop-ship vendors (DSVs) to exchange structured order, inventory, shipment, acknowledgment, and related business data with Walmart. Walmart's current supplier documentation specifically provides an EDI interface for DSVs and identifies transaction formats and connectivity methods for exchanging files with Walmart.com. :contentReference[oaicite:0]{index=0}

The Walmart DSV EDI framework includes transaction sets such as 850 Purchase Order, 855 Purchase Order Acknowledgment, 856 Ship Notice/Manifest, 846 Inventory Inquiry/Advice, and 997 Functional Acknowledgment. Walmart also documents the 856 as the transaction used to communicate shipment contents, order information, product details, packaging, carrier information, and shipment configuration. :contentReference[oaicite:1]{index=1}

How Walmart Drop Ship EDI Works

The workflow begins when Walmart sends order information to the drop-ship vendor. The supplier processes the order, confirms applicable details, manages inventory, prepares the shipment, and sends the required EDI transactions back to Walmart.com. Walmart's DSV documentation identifies the 850 purchase order as an inbound transaction and the 855, 856, 846, and 997 as outbound EDI transactions from the supplier. :contentReference[oaicite:2]{index=2}

The purchase order establishes the order information that the supplier uses for fulfillment. The subsequent shipment notice connects the physical shipment with that originating order, helping Walmart associate the products, quantities, packaging, and carrier information with the customer fulfillment process.

This electronic flow complements Walmart's DSV order interfaces, which also support order requests, cancellations, status updates, confirmations, and error files. :contentReference[oaicite:3]{index=3}

Key Walmart Drop Ship EDI Transactions

Each transaction serves a specific stage of the drop-ship process. Suppliers should implement the exact transaction requirements applicable to their Walmart relationship and current technical documentation.

  • 850 Purchase Order: Communicates purchase-order information from Walmart to the supplier.
  • 855 Purchase Order Acknowledgment: Communicates supplier acknowledgment information associated with the order.
  • 846 Inventory Inquiry/Advice: Communicates inventory availability and related inventory information. :contentReference[oaicite:4]{index=4}
  • 856 Ship Notice/Manifest: Communicates shipment contents, order references, product information, packaging, carrier details, and shipment configuration. :contentReference[oaicite:5]{index=5}
  • 997 Functional Acknowledgment: Provides an electronic acknowledgment associated with EDI transaction receipt and processing.

A supplier's Drop Ship Inventory represents inventory available for fulfillment directly through the supplier's shipping operation. Accurate inventory information helps align available stock with Walmart order activity and supports timely fulfillment decisions.

EDI Connectivity and File Structure

Walmart documents several connectivity options for DSV EDI, including AS2, VAN, SFTP, and solution-provider connections. The appropriate method depends on the supplier's integration arrangement with Walmart. :contentReference[oaicite:6]{index=6}

For production EDI over SFTP, Walmart specifies file naming conventions that incorporate the DSV identifier, creation date, creation time, and a sequence component. Walmart also defines segment, element, and field delimiters for its EDI files. These details matter because the receiving system uses the expected structure to interpret transaction data consistently. :contentReference[oaicite:7]{index=7}

Supplier ERP and order-management systems should preserve the identifiers used across orders, shipments, products, and financial records. The chart of accounts remains an ERP accounting structure rather than an EDI transaction requirement, but ERP integration can use fulfillment and billing data to support appropriate accounting classification.

Invoices, Taxes, and Financial Records

Shipment information eventually connects with financial processing. An EDI Invoice represents structured electronic billing information and can connect an invoiced transaction with the relevant order and fulfillment records.

Tax validation should consider ship-from and ship-to locations, applicable jurisdiction rules, exemptions, nexus, and product taxability. For drop-ship transactions, the location of the supplier and destination can be important when determining sales or use tax treatment and supporting tax reconciliation.

Maintaining consistent order, shipment, invoice, and payment references gives finance teams a traceable transaction chain. This supports accounts receivable, reconciliation, reporting, and vendor-management activities without treating the 856 as an isolated logistics document.

Operational Best Practices

  • Use Walmart's current DSV EDI specifications as the authoritative source for transaction mappings and required fields.
  • Keep product, order, inventory, shipment, and carrier identifiers synchronized between the ERP, warehouse, and EDI environment.
  • Validate 856 shipment data against the actual shipment before transmission, including quantities, packaging, product identifiers, and order references.
  • Monitor functional acknowledgments and maintain traceability across related EDI transactions.
  • Maintain consistent tax and accounting data when shipment records flow into invoicing and financial reporting.
  • Test representative fulfillment scenarios and retain transaction records for reconciliation and operational reporting.

Walmart's current DSV documentation provides transaction-specific specifications and examples, so suppliers should use those materials rather than relying on a generic EDI 856 implementation guide. :contentReference[oaicite:8]{index=8}

Summary

Walmart Drop Ship EDI enables DSVs to exchange structured order, inventory, acknowledgment, shipment, and related data with Walmart.com. The 856 Ship Notice/Manifest is particularly important because it communicates shipment contents and configuration, while the surrounding EDI transactions connect ordering, inventory, fulfillment, and financial workflows. Accurate mappings, reliable ERP integration, consistent identifiers, and current Walmart specifications support efficient drop-ship operations and dependable business reporting. :contentReference[oaicite:9]{index=9}
