How to Simplify Your Third-Party Logistics (3PL) Integrations Using EDI Software

The complexity of 3PL integration

Working with a 3PL typically involves seven core EDI transaction types.


Third-party logistics (3PL) providers offer additional support for specific stages of shipping operations, serving as links in outsourced distribution and fulfillment stages of the supply chain. While 3PL services have always been a significant player in supply chain operations, their involvement continually increases as companies’ sourcing, manufacturing, and customer bases become steadily more multinational.

In order to be effective, brands and 3PL providers must establish dynamic connections for shared visibility of real-time data flows. For this reason, your 3PL must be integrated with the EDI system.

When executed correctly, 3PL EDI integration optimizes efficiency through enhanced visibility and the automation of retail order fulfillment. Furthermore, you can connect with an expanded range of companies and trading partners, enabling you to ultimately deliver more products to more customers.

However, for most manufacturers, 3PL integrations are a tangled web of EDI connections. Yet it doesn’t have to be.

If your company works with several 3PLs, it weighs heavily on your shoulders to build and maintain multiple custom integration environments. With legacy EDI systems you’re creating point-to-point integrations for all your transaction types, for each 3PL. In some cases, there will be a need for integrating with fourth- and fifth-party logistics systems, furthering the convolution.

The trick to simplifying this muddled system is to set up your transactions as efficiently as possible using a centralized EDI core rather than point-to-point integration.

What happens within a typical 3PL integration

Working with a 3PL normally involves seven core EDI transactions types. Here’s a step-by-step breakdown, to help you understand the process flow of these transactions.

3PL Integration

856 – Ship Notice Manifest. The 856 Ship Notice Manifest, triggered by the supplier, notifies the customer that the shipment is on its way and allows both parties to track its progress in their TMS systems. It also serves as a pre-receipt to assist the customer in their receiving operations.

943 – Warehouse Stock Transfer Shipment Advice. The 943 Warehouse Stock Transfer Shipment Advice is the EDI document manufacturers and distributors use to tell third-party or remote warehouses that products are being sent to their location. It includes detailed information about the specific items.

944 – Warehouse Stock Transfer Receipt Advice. The 944 Warehouse Stock Transfer Receipt Advice is used by a receiving location to advise the depositor or its agent that a transfer shipment has been received. It includes detailed information about the product that has been received in the 3PL warehouse system.

940 – Warehouse Shipping Order. The 940 Warehouse Shipping Order is the EDI transaction sent by the supplier to third-party logistics providers (3PLs) to formally request the shipment of goods from a specified warehouse to a buyer’s location.

945 – Warehouse Shipping Advice. The 945 Warehouse Shipping Advice is sent from a 3PL provider or remote warehouse to notify them that a shipment has taken place.

850 – Purchase Order. The 850 Purchase Order is an electronic purchase order sent from a buyer to a seller, serving as a formal order for goods or services.

810 – Invoice. The 810 Invoice is the electronic version of a paper-based invoice, sent in response to an 850 Purchase Order, serving as a request for payment once goods have shipped or services have been provided.

How do these EDI transaction types usually interact with one another?

Suppose you’re a manufacturer taking orders from customers online. Your website will pass orders into your ERP, or system of record, which will then communicate via EDI with your 3PL provider’s system so that the order can be sent to the customer.

The transaction begins when a customer sends you an 850 (purchase order). You will then send a 940 (warehouse shipping order) to your 3PL asking for the order to be fulfilled.

Once your 3PL fulfills the order, they send an 856 (ship notice manifest) on your behalf to the customer and then communicate back to you via a 945 (warehouse shipping advice) that the shipment has left the warehouse. The 945 can include information like the shipment identification, item, quantity, where it’s shipping, the transportation method and shipping service level.

Once you receive the 945, you can invoice your customer with an 810 (invoice), because you have confirmation that the product has been shipped.

943 and 944 EDI Stock Transfer Transactions

This covers most of our diagram (at the top of this section), but how do the 943 (warehouse stock transfer shipment advice) and 944 (warehouse stock transfer receipt advice) transactions fit into a 3PL EDI integration?

To meet customer demands, you need to ensure that your 3PL is stocked with your product. You must order directly from your supplier and instruct them to send the product to your 3PL, by sending them an 850. In the meantime, you send a 943 to your 3PL to let them know goods are coming into their warehouse and when the product will be delivered. Once your supplier prepares the shipment, they send the 3PL an 856 to confirm the shipment’s contents. The supplier can then send you an 810 (invoice).

Once your 3PL receives the product from your supplier, it will send you a 944 to notify you that they received the product. The 944 serves as a receipt of your order and includes any adjustments that need to be made to the original 943 due to potentially damaged or missing products.

How to manage your 3PL EDI integrations with maximum efficiency

Common problems that companies face usually come from the complexity of the 3PL logistics process itself, combined with outdated EDI integration challenges with both new and existing trading partners. Heavy reliance upon antiquated forms of communication rather than automation slows essential information exchanges, leading to detrimental frustration between companies.
