3PL TMS software for multi-client freight operations.

What is a 3PL transportation management system?

A 3PL transportation management system (TMS) is the software a third-party logistics provider uses to plan, execute and bill freight on behalf of its customers. It records each customer’s shipment requirements, arranges the carrier, tracks the move, captures delivery documents, and prepares both the customer invoice and the carrier payable.

The difference from a shipper’s TMS is the number of clients. A shipper manages its own freight. A 3PL manages freight for many shippers at once, each with its own references, rates, service rules and billing requirements. The system has to keep those customers separate while giving your team one place to work.

Third-party logistics covers a wide range of services: truckload and LTL brokerage, managed transportation, cross-docking, warehousing and fulfillment. A 3PL TMS focuses on the transportation part. Inventory and work inside a building usually belong to a warehouse management system, covered in the TMS vs WMS guide.

Core features of 3PL TMS software

Treat the table as a starting checklist. The workflow behind each row matters more than a feature name on a product page.

Run many clients with different rules

Every customer of a 3PL brings its own way of working. One needs a purchase order number on every invoice. Another requires delivery appointments booked before dispatch. A third only accepts carriers from an approved list. A 3PL TMS has to hold those rules per customer so your team does not rely on memory or sticky notes.

• References: purchase order, shipment and consignee references stay searchable and print on documents and invoices.
• Service rules: approved carriers, equipment types, appointment requirements and escalation contacts are set for each customer.
• Rates: contract rates, spot quotes and accessorial schedules apply only to the customer they belong to.
• Visibility: a customer sees its own shipments and documents, never another client’s.
• Billing: invoice layout, grouping, due dates and required backup documents follow each customer’s terms.

Ask the vendor to set up two customers with conflicting rules during the demo. If both run side by side without manual workarounds, the system fits a multi-client operation.

Bill each client correctly

A 3PL earns revenue on the customer side and pays carriers on the other. Each shipment carries a sell rate, a buy rate, and any accessorials that changed after booking, such as detention or a lumper charge. The TMS should connect all of them to one shipment so the customer invoice and the carrier payable reconcile.

Many 3PLs also sell services a transportation invoice does not cover, such as storage, handling or kitting. Decide whether those charges are billed from the TMS, the warehouse system or your accounting system, and make sure no service is billed twice or missed. The invoicing workflow guide covers a ready-to-invoice checklist in detail.

Connect shippers, carriers and warehouses

A 3PL TMS sits between systems it does not own. Shippers send orders from their ERP or order systems. Carriers send status updates and invoices. Your warehouse, or a partner’s, releases the freight. Integration decides how much of that arrives automatically and how much your team re-keys.

Electronic data interchange (EDI) is still common in freight. Typical motor-freight transaction sets include:

• 204 load tender: a shipment offered to a carrier, or received from a shipper.
• 990 response to a load tender: the carrier’s acceptance or rejection.
• 214 shipment status message: pickup, in-transit and delivery events.
• 210 freight details and invoice: the carrier’s freight bill.

APIs and file imports are also common, especially with tracking providers and newer platforms. For every connection, ask who builds and maintains it, how errors reach your team, and whether it carries setup or per-transaction fees. The TMS pricing guide explains how integration costs usually appear in a quote.

Plan for LTL and truckload freight

Full truckload (FTL) and less-than-truckload (LTL) freight work differently, and many 3PLs handle both. The data a shipment needs, the exceptions you manage and the billing checks all change with the mode.

If LTL is part of your business, test how the system rates a shipment, records a reweigh or reclass correction, and passes an adjusted charge to the customer. For truckload, focus on tendering, carrier compliance and exception handling.

How to evaluate a 3PL TMS

• Map your freight: modes, main lanes, typical volume and the customers with the most demanding rules.
• Bring real examples: one routine load, one exception and one customer invoice.
• Ask the vendor to run the full workflow on the same shipment, from order intake to customer invoice and carrier payment.
• Check integration ownership: who builds each EDI or API connection, and what happens when one fails.
• Confirm data export: you should be able to take customer, carrier, shipment and invoice records with you.
• Price the whole setup, including users, integrations and onboarding.

Use the TMS buyer’s guide scorecard to compare vendors on the same terms, and the implementation checklist to plan the rollout.
