What is a transportation management system (TMS)?

A transportation management system is software that plans, dispatches, tracks, and bills freight. Diesel TMS is a cloud-based TMS that combines dispatch software, load management, driver app tracking, invoicing, and trucking accounting in one place.

Is there a free TMS for trucking?

Yes. Diesel TMS Unlimited is a free TMS for trucking companies, owner operators, and freight brokers with unlimited users and unlimited loads, no per-user fees, no setup fees, no contracts, and no credit card required. It is ad-supported; TMS Flex and TMS Pro remove ads.

How much does TMS software cost?

Many TMS platforms charge $100 to $500+ per user per month plus setup fees. Diesel TMS costs $0 on the Unlimited plan, $0.40 per user per hour logged in on TMS Flex, or $40 per user per month on TMS Pro, with no contracts or minimums.

Can a TMS handle both trucking and brokerage?

Diesel TMS is built for brokers with assets: dispatch your own trucks and drivers, broker loads to outside carriers, and run both from the same load list, accounting, and customer portal.

Do owner operators and small fleets need a TMS?

Once you are tracking loads, rate confirmations, and invoices in spreadsheets, a TMS saves hours of back-office time. Diesel TMS is free for small trucking businesses, so owner operators can stop using spreadsheets for dispatch at no cost.

What is the difference between a TMS and dispatch software?

Dispatch software assigns loads to drivers or carriers. A TMS covers the whole lifecycle: quoting, dispatching, tracking, documents, invoicing, carrier pay, driver pay, and accounting integrations such as QuickBooks Online. Diesel TMS includes both.

How do I switch TMS software or import my data?

Diesel TMS includes a Smart Data Import for loads, customers, carriers, and locations from CSV or spreadsheets, plus free onboarding and training, so switching from another TMS or from Excel takes days, not months.

Does Diesel TMS integrate with QuickBooks Online?

Yes. The two-way QuickBooks Online integration syncs customers, vendors, invoices, bills, payments, credit memos, and journal entries, and is included on every plan.
