Salesforce B2B Commerce connects to third-party logistics (3PL) providers through three layers. Commerce extensions handle storefront logic such as pricing and inventory. Salesforce Order Management handles routing and fulfillment orders. An integration layer such as MuleSoft moves data between Salesforce and your 3PL, warehouse, and ERP systems.
Two things have changed since most guides on this topic were written. Salesforce Commerce Cloud is now Agentforce Commerce, though B2B Commerce and Order Management keep their names. And the “Integration Framework” is no longer the recommended starting point. This guide covers what to use now.
What Is the Salesforce B2B Commerce Integration Framework Today?
The original framework is still supported, but Salesforce points developers to something newer. In the Winter ’24 release, Salesforce introduced Commerce extensions for pricing, inventory, shipping, taxes, and other services. The company recommends extensions over the checkout integrations framework because they allow more targeted customization and cover more Commerce domains.
An extension is a custom Apex class, called an extension provider. A domain extension can add to or replace default behavior for an area such as pricing or cart calculation. You register the class and map it to a store with the Salesforce CLI Commerce plug-in or the Commerce APIs.
One limit matters for logistics teams. Payments can’t be customized with an extension yet, so payment work still uses the integrations framework. See the extensions guide for the current list.
How Does Salesforce B2B Commerce Connect to a 3PL Provider?
Salesforce’s Order Management documentation describes the handoff in four steps:
- A buyer places an order in your B2B store.
- A flow allocates the order and creates fulfillment orders for locations, based on delivery groups and inventory.
- The system exports each fulfillment order to the fulfillment provider.
- The provider returns an Advance Shipping Notice (ASN). Order Management then creates shipment records and marks the fulfillment order as Fulfilled or Cancelled.
This pattern comes from the Order Management Implementation Guide. Salesforce defines the order lifecycle and statuses. You build the export and the ASN return for your specific provider, which is where an integration platform earns its keep.
Commerce Extensions, Checkout Integrations, or MuleSoft: Which One Fits?
Most 3PL projects use more than one of these. Each solves a different problem.
| Option | Best for | Watch for |
|---|---|---|
| Commerce extensions | Live inventory or shipping logic during browsing, cart, and checkout | Requires Apex; registered per store |
| Checkout integrations | Shipping, tax, and payment providers in checkout | Payments can’t move to extensions yet |
| Order Management | Routing, fulfillment orders, shipments, returns | Export to the 3PL still needs an integration |
| MuleSoft | Connecting the 3PL, WMS, and ERP to Salesforce | Needs API design and governance up front |
What Order Routing and Inventory Features Does Salesforce Provide?
Order Management works with Omnichannel Inventory to decide where an order ships from. According to Salesforce Help, the Get Inventory Availability action checks products across up to 100 locations or location groups. You can also create, transfer, fulfill, and release reservations in a flow.
The Routing API adds more control:
- It returns combinations of locations that can fill an order within a set limit of shipment splits.
- It ranks location sets by average distance to the recipient.
- It holds, confirms, and releases fulfillment capacity at a location.
Treat your 3PL as a location in this model. Routing rules can then weigh stock, distance, and capacity the same way they do for your own warehouses.
How Is Agentforce Commerce Changing B2B Fulfillment?
Salesforce made a set of B2B Commerce updates generally available in June 2026. Several affect how buyers interact with your supply chain:
- Buyer Agent: An AI agent built into B2B Commerce that helps buyers find products, manage orders, and check out through chat on WhatsApp, SMS, and other channels.
- AI-driven B2B Search: Search that reads intent, so a buyer can describe a part’s requirements without knowing the SKU.
- Round Trip Quoting: Request for Quote already existed. Quote to Cart now lets sellers send an approved quote to the buyer as a cart.
- Headless Reference Architecture: A reference app and API library for building storefronts in frameworks like React or Vue on one shared back end.
Details are on the Salesforce B2B Commerce blog. The July release added boost and bury rules, search analytics through Data Cloud, and CSV/JSON cart import and export, per the July update.
Salesforce’s customer example is Siemens, which has launched Agentforce B2B Commerce in more than 25 countries. The company reports about 90% growth in gross merchandise value over the prior year.
An agent can only answer “where is my order?” with data it can reach. The Buyer Agent sits on top of your logistics integration, so a weak 3PL feed shows up as a weak agent.
What Should You Check Before Integrating a 3PL With Salesforce?
Before you build, settle these five points:
- System of record. Decide which system owns inventory, orders, and shipment status.
- Sync timing. Pick which events need near-real-time updates (stock changes, shipments) and which can run in batches.
- Partial shipments. Confirm your 3PL can send an ASN for part of an order, and that your flow handles it.
- Failure handling. Define what happens when the 3PL rejects an order, an API times out, or a message arrives twice.
- Data residency. If you operate in India or another regulated market, check where integration workloads run. MuleSoft on Hyperforce in India is one option for local residency.
Cloud Odyssey’s Point of View
We are a Salesforce Summit Partner and MuleSoft expert, and Salesforce India named us Multi-Cloud Partner of the Year for 2026. These are the practices we recommend on logistics projects.
Design the return path first. Most teams plan how an order reaches the 3PL and treat shipment status as an afterthought. Customers, support teams, and AI agents all depend on that status coming back. Map the ASN, partial shipments, and exceptions before you build the outbound flow.
Use an API layer instead of point-to-point links. A direct connection between B2B Commerce and one 3PL works for a pilot. It gets expensive when you add a second warehouse or swap providers. With MuleSoft integration, the 3PL connection becomes a reusable API. Our multi-cloud implementation guide explains when that investment pays off.
Start narrow with the AI layer. Pilot Buyer Agent on a high-frequency reorder account before a full rollout. Our retail Agentforce example shows the same pattern: live order and delivery data come from MuleSoft, and the agent answers from that data.
Choose extensions for new storefront work. For new pricing, inventory, or cart logic, build on extensions. Keep the checkout integrations you already have running until there is a reason to move them.
Our Commerce Cloud implementation services cover B2B Commerce, Order Management integration, and headless builds. If you already run a store and want a second opinion, a Salesforce health check is a good first step. For ongoing support, see our managed services.

Frequently Asked Questions
It is the original Apex-based mechanism for plugging third-party services into B2B checkout, covering shipping, tax, and payment. It is still supported, but Salesforce recommends Commerce extensions for new customization.
Salesforce documents the order lifecycle for working with an external fulfillment provider, but the provider connection is something you build or buy. Most teams use an integration platform such as MuleSoft or a partner package from AppExchange.
Integrations implement an Apex interface and replace default behavior. Extensions extend a base Apex class and can add to or replace it. Extensions cover more domains, including pricing and inventory.
Yes. Salesforce renamed the suite, which includes B2B Commerce, B2C Commerce, Order Management, Payments, and Point of Sale. B2B Commerce and Order Management keep their product names.
Yes. In Order Management you can model a 3PL as an inventory location. Routing rules and Omnichannel Inventory then treat it like any other location.
