Overview
TruckingOffice is one of the longest-running trucking management systems for owner-operators and small fleets. Built by a former trucking company owner, it focuses on the essentials: dispatching, invoicing, driver settlements, maintenance reminders, and especially IFTA fuel tax reporting (their tagline is “IFTA Is Just The Beginning”). It comes in two versions—Basic (FTL only, load and trip entered together) and Pro (FTL and LTL with a separate load planner).
TruckingOffice is priced by truck count with no per-user fees and no contract, which makes it approachable for a 1–2 truck operation. But it is still a paid product ($25–$130/month plus a PC*MILER routing add-on), and it lacks many features small fleets now expect: a driver mobile app, AI automation, built-in general-ledger accounting, load board integration, and a modern interface.

|---|---|---|
| Free Tier | 30-day trial only | $0/month (Free forever, unlimited trucks) |

| Mid Size (3–7 trucks) | $55/month (Basic) or $75/month (Pro) | $0/month (Free) or $40/user/month (Pro) |
| Fleet (8+ trucks) | $90/month (Basic) or $130/month (Pro) | $0/month (Free) or $40/user/month (Pro) |

| PC*MILER Mileage Add-on | +$5 to +$25/month (+$2/truck over 15) | Mileage and mapping included |
Note: TruckingOffice has no per-user fees and no contracts, but the free trial ends after 30 days and a credit card is required to continue. Diesel TMS never requires a credit card on the Free plan.
Key Differences
Free Forever vs Free Trial
- TruckingOffice: 30-day trial, then $25–$130/month. Costs step up as you add trucks (1–2, 3–7, 8+).
- Diesel TMS: Free forever with unlimited trucks. Upgrade to Pro ($40/user/month) only if you want an ad-free experience—the features are the same.
Driver App & Communication
- TruckingOffice: Web-based system. Drivers typically call or text dispatch; paperwork is uploaded manually.
- Diesel TMS: Free driver app with load details, status updates, GPS check calls, document scanning, and in-app chat. ELD integrations with Samsara and Motive.
Automation & AI
- TruckingOffice: Manual load entry. Automatic mileage via PC*MILER add-on. No AI features.
- Diesel TMS: AI Email to Quote turns emailed rate requests and documents into loads and quotes, AI Search finds anything in natural language, and Zapier connects to 9,000+ apps.
Accounting & Back Office
- TruckingOffice: Invoicing, driver settlements, expense tracking, and reports. Accounting is done in a separate system.
- Diesel TMS: Invoicing, bills, settlements, and full double-entry accounting built in, plus two-way QuickBooks Online sync if you prefer to keep your books there.

The Bottom Line
TruckingOffice earned its reputation by giving owner-operators an affordable way to get off paper and stay on top of IFTA. If that is all you need, it does the job. But at $25–$130/month it is no longer the cheapest option, and it has not kept pace on driver apps, AI, accounting, or integrations.
Diesel TMS gives a one-truck owner-operator or a 20-truck fleet more capability at $0/month than TruckingOffice Pro offers at $130/month—with no truck-count tiers to climb, free onboarding, and live human support. Start free, import your data in minutes, and never pay for another truck.
