What is TMS software?

TMS software - short for transportation management system, also called transport management software or a transport management solution - is software that automates and streamlines the otherwise manual tasks involved in planning and managing the physical transportation of goods.

It replaces spreadsheets, phone calls, and manual carrier bookings with a single system that plans, books, tracks, and documents shipments for shippers, carriers, and logistics service providers (LSPs). If you’re comparing TMS software, that’s the one-line answer. The rest of this article covers what it actually does, the different flavours of TMS on the market, and how to tell if you need one.

What does TMS software do?

Strip away the marketing and most TMS software covers the same core ground, even if the depth and polish vary wildly between vendors:

Carrier selection and shipment booking: comparing carriers and rates, then confirming shipments and triggering the collection process directly with the carrier.
Label generation: producing compliant carrier labels with the right barcodes, routing codes, and service indicators for each carrier and destination.
Documents: generating the paperwork a shipment needs - delivery notes, packing lists, commercial invoices, customs declarations, and carrier-specific forms such as CMRs or despatch advices - usually from a template so your team just clicks and prints.
Shipment tracking: real-time visibility into where a shipment is, from booking through to final delivery, plus exception alerts when something goes off plan (a delayed pickup, a missed delivery window, and so on).
Invoicing and freight settlement: matching carrier invoices against agreed rates and contracted services, so you catch overcharges without a manual audit.
Analytics and reporting: dashboards on delivery performance, cost, and carrier reliability, so decisions are based on data rather than gut feel.
Integrations with carriers’ systems: direct connections to carriers so bookings, labels, and tracking events flow automatically instead of being re-typed into a carrier portal. See our integrations if you want to check which carriers a given TMS actually supports before you commit to one.

Not every TMS does all of this equally well - a system built for shippers, for instance, typically goes deeper on carrier selection and documentation, while a carrier’s own TMS focuses more on route and load optimisation. More on that distinction below.

The definition of a transportation management system

There’s no single, universally agreed definition of TMS software, which is part of why the category feels so fragmented when you start researching it.

At Viya, we define a transportation management system as:

software that automates and streamlines otherwise manual tasks involved with planning and managing the physical transportation of goods

This includes the tasks of all the parties involved in the shipping process - roughly speaking, shippers, carriers, and logistics service providers.

Other definitions are thinner. Supply Chain Management for Dummies simply states a TMS “keeps track of shipments and carriers,” which is technically true but gives you little to work with. The reality is that defining a TMS precisely is hard because its features depend on who it’s built for - and TMSs serve very different users with very different needs (more on this below).

The term is also used loosely by vendors to market their own products, so it’s often unclear whether someone is talking about the general concept of transportation management software, or a specific TMS built for one type of user - small e-commerce shippers or independent carriers, for example. Keeping that distinction in mind will save you a lot of confused sales calls.

The benefits of transportation management systems

Implementing a TMS brings a few concrete benefits to your business:

It improves collaboration and communication among everyone involved in the shipping process - shippers, carriers, LSPs, and receivers - through seamless information exchange, real-time updates, and automated processes. That saves time and reduces administrative overhead.

It makes life easier for your logistics, sales, customer service, and finance teams. Streamlining and automating logistics processes boosts operational efficiency, reduces labour costs, and minimises errors. The point is to take repetitive, error-prone tasks off people’s plates so they can focus on higher-value work, and so you can scale operations without scaling the logistics team at the same rate.

Kinds of transportation management systems

You can roughly divide TMS software by the customers it’s built for:

Shippers
Carriers
Logistics service providers (LSPs)

By shippers, we mean the parties supplying the goods being transported. By carriers, we mean the parties hired to physically move those goods. By logistics service providers, we mean parties handling part of the shipping process on a shipper’s behalf - third-party logistics providers (3PLs) and freight forwarders, for example.

Not every shipment involves all three; plenty of shippers handle their own logistics and transportation. In that case, a shipper benefits from the carrier-facing functionality described below too.

TMSs for shippers

Shipper-focused TMS solutions help choose suitable carriers, book shipments, generate labels and documents, track shipments, and keep customers informed of status. They also typically handle invoicing and payment authorisation. If you’re weighing up how many carriers to route shipments through, our guide on carrier strategies is a good next read, and if you’re leaning towards one carrier for everything, see what a single-carrier strategy actually involves.

TMSs for carriers

Carrier-focused TMS solutions concentrate on pricing, planning, and route optimisation to maximise vehicle capacity. If a shipment is less than a full truckload, a carrier’s TMS can consolidate loads to make the most efficient use of available capacity.

TMSs for LSPs

LSPs often carry the responsibilities of both shippers and carriers, so their TMS solutions blend functionality from both sides: physical transportation, carrier relationship management, route optimisation, and load consolidation.

Many vendors try to serve more than one of these groups at once, given the overlap in requirements - so an LSP-focused TMS often borrows features from carrier-focused TMS software, and vice versa.

In short, different kinds of TMSs cater to the diverse needs of shippers, carriers, and LSPs, each optimising the transportation process for its own target customers. Consider the range within each category too - from a self-employed trucker to an international carrier, or from a regional retailer to a multinational brand - and you can see why the TMS market looks so fragmented from the outside.

How a TMS, ERP, and WMS work together

Most businesses run their TMS alongside an enterprise resource planning system (ERP) and a warehouse management system (WMS). Think of the TMS as the conductor of the shipping process: when an order is confirmed in the ERP, it signals the TMS to arrange the shipment while the WMS gets the goods ready for pickup. The TMS then arranges pickup, labelling, and transport documentation as the order is picked and packed. It keeps information flowing between systems so the ERP can manage the overall business, the WMS can manage the warehouse, and the TMS bridges the two by coordinating transportation from start to finish.

Can a TMS be used standalone?

Yes. A business can run a TMS without an ERP or WMS in place. Integrating a TMS with ERP and WMS can add benefits and streamline end-to-end operations, but it isn’t a requirement - a standalone TMS still delivers real value by focusing specifically on transportation management and logistics operations.

When to get a transportation management system

Many companies delay getting a TMS longer than they should, simply because they don’t recognise the signs it’s time to switch:

Increasing complexity: as your business grows, so does the complexity of your transportation needs. Juggling multiple carriers, varied shipping requirements, and shifting customer demands is a strong signal a TMS would help.
Inefficient processes: spreadsheets are error-prone and require manual data entry. If your team spends too much time on repetitive data entry, shipment tracking, or carrier communication, a TMS automates that work.
Lack of visibility: if you can’t track and monitor each shipment’s status in real time, a TMS gives you end-to-end visibility, exception notifications, and accurate delivery estimates for customers.
Cost control challenges: without proper analytics, it’s hard to spot cost-saving opportunities or optimise transportation spend. A TMS gives you cost analysis, rate comparison, and optimisation capabilities to make data-driven decisions.
Customer service issues: delays, order inaccuracies, or poor communication about shipments all point to a visibility gap a TMS is built to close.

If several of these resonate, it’s worth seriously considering swapping the spreadsheet for a modern TMS. For a sharper checklist of buying triggers, see our piece on unique buying reasons for implementing a TMS.

Your next steps to getting a TMS

Start by assessing your organisation’s specific transportation needs and challenges: shipment volume, complexity of logistics processes, and the level of visibility and control you actually need.

The TMS market has a lot of established vendors, and no single one is the right fit for everyone - what matters is evaluating features, scalability, and support against your own requirements rather than a generic feature checklist. If you haven’t decided whether to build this in-house, buy a TMS, or outsource the whole thing, own a TMS or outsource logistics walks through that trade-off in more detail.

Once you’ve shortlisted providers, engage with industry experts, attend trade shows, and ask for recommendations from businesses with a similar shipping profile to yours. When you’ve selected a TMS, work closely with the provider on implementation and integration with your existing systems - a TMS is a strategic tool for your transportation operations, not just a piece of software you switch on.
