What is EDI 945 Warehouse Shipping Advice?

Definition

EDI 945 Warehouse Shipping Advice is a standardized electronic transaction used by a warehouse or third-party logistics provider to communicate shipment details back to the party that requested the shipment. It confirms that goods were shipped and provides structured information about what left the warehouse, when it was shipped, and where it was sent.

EDI 945 commonly follows an EDI 940 Warehouse Shipping Order. The 940 communicates the shipping instruction, while the 945 communicates the warehouse's shipment confirmation. This creates a connected electronic record across order management, inventory, logistics, and financial workflows.

How EDI 945 Works

The process begins when a warehouse receives a shipping instruction containing the items, quantities, destination, and required shipping details. After the goods are picked, packed, and dispatched, the warehouse generates an EDI 945 and sends it to the requesting organization.

  • Order reference: Connects the shipment to the original warehouse request or related order.
  • Shipment details: Communicates shipment date, carrier information, tracking references, and destination details.
  • Item information: Identifies products, quantities shipped, units of measure, and relevant item references.
  • Receipt preparation: Gives the receiving organization structured information for expected inbound goods.

This electronic confirmation allows downstream systems to update fulfillment and inventory records using a consistent transaction reference.

EDI 945 and Order Fulfillment

EDI 945 plays an important role in the procure-to-pay and order fulfillment chain because it provides evidence that an instructed shipment has actually left the warehouse. When a purchase order is connected to warehouse and fulfillment records, the shipping advice helps maintain continuity between the requested goods and the physical movement of inventory.

The transaction can support shipment tracking, inventory updates, customer service, and reconciliation between ordered and shipped quantities. If an order requests 1,000 units but the warehouse ships 950, the EDI 945 can communicate the actual shipped quantity so downstream systems can process the difference appropriately.

Key Data and Financial Relevance

EDI 945 information can include shipment identifiers, warehouse codes, carrier details, item identifiers, quantities, dates, and destination information. These details create a traceable record that can support operational reporting and accounting controls.

Accurate shipping information can help finance teams connect physical fulfillment with revenue, inventory, accrual, and general-ledger processes. It also provides supporting evidence when organizations reconcile shipment activity with invoices and other financial records.

An EDI Invoice may contain billing information that needs to align with the goods actually shipped. Comparing invoice quantities with EDI 945 shipment data can therefore support accurate transaction processing and financial reporting.

Tax and Compliance Considerations

Shipping information can affect tax treatment when tax rules depend on ship-from and ship-to jurisdictions. Accurate addresses and shipment records help organizations validate applicable rates, exemptions, nexus considerations, and audit documentation.

For transactions involving jurisdiction-specific tax requirements, shipping records can provide supporting evidence for use tax analysis and related compliance reviews. Where electronic tax workflows are used, shipment information can also contribute to accurate EDI Tax Filing records by connecting transaction activity with relevant location and tax data.

EDI 945 in Warehouse and Logistics Operations

Shipping processes depend on accurate communication between warehouses, carriers, buyers, sellers, and receiving locations. EDI 945 provides a standardized way to transmit shipment confirmation without requiring each party to maintain separate manual records.

The transaction can also support exception management by making differences between requested, shipped, and subsequently received quantities easier to identify. This is useful for inventory reconciliation, customer notifications, fulfillment reporting, and operational performance analysis.

Best Practices

  • Maintain consistent references: Preserve order, shipment, warehouse, and item identifiers across connected transactions.
  • Validate quantities: Confirm that shipped quantities and units of measure accurately reflect the physical shipment.
  • Keep address data accurate: Maintain reliable ship-from and ship-to information for logistics and tax-related processes.
  • Connect financial records: Link shipment confirmations with invoices, inventory records, and relevant accounting workflows.
  • Use structured reconciliation: Compare ordered, shipped, and received quantities to maintain accurate operational records.

Summary

EDI 945 Warehouse Shipping Advice electronically confirms that goods have been shipped from a warehouse and communicates the key details needed by downstream systems. By connecting warehouse execution with procurement, inventory, logistics, tax, and finance processes, EDI 945 improves transaction traceability and supports accurate operational and financial reporting. Automated Remittances can complement these structured workflows later in the transaction lifecycle by supporting electronic remittance communication and reconciliation after related financial obligations are processed.
