Fullbay is one of the best-known names in diesel and heavy-duty shop management, and for good reason. But it isn’t the only option, and the right fit depends on how your shop runs, how many trucks you turn in a week, and whether you want the software to answer your phone too.
Below are five directions to look if you’re shopping for a Fullbay alternative in 2026, starting with an all-in-one that adds a built-in 24/7 AI receptionist. For a direct, feature-by-feature look, see Tradellen vs Fullbay.
What to look for in a Fullbay alternative
- Repair orders that fit a diesel shop — complaint, cause and correction, with clear status from intake to paid.
- Unit and VIN history — every truck and trailer on file with mileage, engine hours and past work.
- Parts, approvals and invoicing in one flow, ideally with card payments and QuickBooks sync.
- How the phone is handled — breakdowns don’t wait for business hours, so answering matters.
- Pricing you can predict — flat pricing beats per-seat math when you add technicians.
1. Tradellen — best all-in-one with a built-in receptionist
Tradellen runs the core work a diesel shop needs, repair orders with complaint, cause and correction, unit and VIN history, parts status, approvals and invoicing with card payments, and adds what most shop systems don’t: a built-in 24/7 AI receptionist. Aria answers breakdown and after-hours calls, captures the unit and location, and opens a roadside repair order automatically, so the jobs other shops lose to voicemail land on your board. Pricing is flat and per-shop with no per-technician fees, and guided setup and migration are included. See the truck & trailer repair software overview or the focused diesel repair shop software page.
2. Diesel-specific shop suites
Purpose-built diesel platforms, Fullbay among them, focus tightly on heavy-duty repair workflows and suit shops that want a deep, diesel-specific toolset. They tend to be feature-rich; the usual trade-offs are price and setup time. Check each vendor’s site for current plans, and weigh whether you also need the phone answered after hours.
3. General auto and truck shop management
Broader automotive shop-management tools, such as Shopmonkey, serve mixed fleets and general repair as well as heavy-duty work. They can fit shops that handle more than just trucks, though diesel-specific details like DOT and unit history may be lighter. Confirm the specifics on their site.
4. Fleet maintenance platforms
If your priority is maintaining your own fleet rather than running a repair shop for customers, fleet-maintenance tools such as Fleetio track vehicles, service schedules and costs across a fleet. They’re built for fleet owners, not shop invoicing, so they usually pair with, rather than replace, a shop system.
5. A QuickBooks plus answering-service stack
Some small shops run on spreadsheets or QuickBooks plus a traditional answering service. It’s cheap to start, but the pieces don’t talk to each other, and an answering service takes a message rather than opening a repair order. An all-in-one that also answers the phone usually pays for itself once you count the missed breakdown calls. See truck repair answering service for how a 24/7 option compares.
The bottom line
If you want a diesel-specific suite, look at the purpose-built platforms. If you want one simple system that runs repair orders and answers the phone 24/7 on flat pricing, start with Tradellen and compare it directly on Tradellen vs Fullbay.
