Fullbay Cost: What Heavy-Duty Truck Shops Actually Pay for Shop Software in 2026

Fullbay cost starts at $188/month for a single user, with each additional user running $89/month on top of that. A shop running three full users hits $366/month minimum—before add-ons, integrations, or multi-location fees. For independent heavy-duty and diesel shops comparing truck shop software cost, that per-user pricing model is the number that matters most, because it scales against you as your team grows.

Breaking Down Fullbay Pricing: What the Plans Actually Cost

Fullbay's published pricing is straightforward on the surface: $188/month Basic, which covers one full user license and up to five users total. After that first included seat, every additional full user costs $89/month. That means:

• 1 user: $188/month
• 3 users: $366/month
• 5 users: $544/month
• 8 users: $810/month
• 10 users: $988/month — just under $1,000/month for a medium-sized shop

And that's before you're on a higher tier. Fullbay also offers a Pro plan and an Enterprise tier with pricing that's not publicly listed — meaning you're calling their sales team and negotiating. For most independent shops, that's where the real sticker shock hits. Shops with a service writer, two or three techs who need system access, and a shop foreman can easily find themselves at $700–$900/month just in seat licensing, not counting annual contract commitments that some plans require.

This isn't unique to Fullbay. It's the enterprise SaaS playbook: price low at entry, then scale revenue per customer as headcount grows. The problem is that model was designed for dealerships and large fleet operations — not the independent 3-bay diesel shop in Amarillo or the 6-bay heavy truck shop outside Calgary trying to run lean.

Why Per-User Pricing Hits Independent Diesel Shops the Hardest

Heavy-duty and diesel repair is different from automotive. Jobs are multi-day. Fleet accounts want portal access. Techs clock in and out of jobs, service writers build complex estimates, and owners want real-time visibility into WIP (work-in-progress). That means more people need system access, not fewer — which is exactly the wrong profile for a per-user pricing model.

Consider a realistic independent shop scenario: one owner-operator, two flat-rate diesel techs, one service writer, and a parts manager. That's five people who need meaningful software access. Under Fullbay's Basic plan, you're at $544/month. Annualized, that's $6,528/year in software overhead before you've bought a single scan tool adapter or paid for your MOTOR or Alldata subscription.

Compare that to what a shop management software monthly fee looked like five years ago — most independent shops were spending $150–$300/month total on shop management tools. The market has shifted hard toward SaaS pricing that benefits the software company's ARR (annual recurring revenue) metrics, not your P&L. When you're evaluating heavy truck repair software price, you have to look at your actual headcount and project 12 months out, not just the entry price point.

What You're Actually Getting for the Money — and What's Missing

To be fair: Fullbay does a lot of things well. It was purpose-built for heavy-duty and diesel, which matters. It handles fleet accounts, preventive maintenance scheduling, parts inventory, and integrations with parts vendors. For a shop doing $1.5M+ in annual revenue with stable headcount, the ROI math can work out if the platform genuinely tightens up your billing cycle and reduces unbilled labor.

But here's what I hear consistently from independent shop owners who've run Fullbay for a year or two: the per-user fee structure makes them reluctant to give access to people who would actually benefit from it. A tech who could clock his own jobs and reduce service writer workload doesn't get a login because the owner doesn't want another $89/month line item. That friction defeats the purpose of the software. You end up with an expensive system that only two or three people use, with the rest of your workflow still running on paper or whiteboards.

The other gap is flat-rate labor integration for Class 4–8 trucks. Heavy duty shop software flat rate capability — meaning access to published labor times for commercial vehicles — is either an add-on or limited depending on your plan level. If you're quoting based on MOTOR Commercial Truck or similar data, verify what that costs on top of your base subscription before you sign anything.

Alternatives Worth Comparing When You're Evaluating Diesel Shop Software Pricing

When independent shop owners ask me what else is in the market for affordable truck repair software, here's how I frame the comparison: you're looking for three things — purpose-built for heavy-duty workflows, flat-rate or unlimited-user pricing, and a company that actually picks up the phone when something breaks.

Some options that come up regularly in this category:

• Fullbay — purpose-built for heavy-duty, strong fleet features, per-user pricing that scales against you. Best fit for larger shops or those with stable small teams.
• Shopmonkey — polished UI, primarily automotive-focused; heavy-duty shops often find it lacking on the commercial vehicle side. Per-user pricing applies here too.
• Shop-Ware — solid workflow tools, more automotive than heavy-duty, pricing varies by plan.
• Wrenchpod — built specifically for independent heavy-duty and diesel shops, with flat-rate pricing and unlimited users. No per-seat fees. If you've got five people who need access, you pay the same as if you have two. That's the fundamental model difference.

The truck repair shop software unlimited users model isn't just a feature — it changes how you deploy the tool. When there's no seat cost, you give access to everyone who benefits: techs, service writers, parts people, even a working owner who wants to check WIP from the road. That's how you actually get ROI from shop software.

When comparing truck shop software cost across platforms, build a 12-month projection using your actual headcount. Don't use the minimum user count. Use your real team. That number is the honest cost of each platform for your shop.

How to Control Software Costs Without Cutting Corners on Capability

Software overhead in a diesel repair shop should be evaluated the same way you evaluate any other operating cost: what does it produce relative to what it costs? Here's a framework that actually works:

1. Calculate your effective cost per work order. If you're closing 80 work orders a month and paying $600/month for software, that's $7.50 per RO in software overhead. Benchmark that against what you're recapturing in unbilled labor, faster invoicing, and reduced parts shrinkage.
2. Audit who actually uses the system. If you're paying per user and half your licensed seats are barely touched, you're wasting money. Either train the team to use it or drop the seats.
3. Watch for annual contract traps. Some platforms discount 10–15% for annual commitments but lock you in if the software doesn't work for your workflow. Month-to-month costs more upfront but gives you an exit.
4. Add-on creep is real. Integrations, labor guide data, customer-facing portals, text messaging features — these are often sold separately. A flat rate diesel shop management system that includes these in the base price is worth more than a low headline number with a long add-on menu.
5. Get a real demo with your actual workflow. Run a multi-day fleet job through the demo. Build an estimate with parts markup. Close a job and trigger a customer invoice. If the demo rep can't do that with your real workflow, the software isn't ready for your shop.

Independent shop software that fits your business shouldn't require enterprise-level spend. The right tool for a 4-bay diesel shop in Texas or a 6-bay heavy truck operation in Ontario is not the same product built for a 20-location fleet service provider — and the pricing shouldn't pretend it is.

The Bottom Line on Fullbay Cost vs. What Your Shop Actually Needs

Fullbay is a legitimate product. If you're running a larger operation, have stable headcount, and do heavy fleet work, the feature set justifies the cost for some shops. But if you're a true independent — say, under $2M in annual revenue, with a team of 3–8 people who all need system access — the per-user pricing model is going to cost you $500–$1,000/month for software overhead that a flat-rate alternative would price at $200–$350/month. That's a $3,000–$8,000/year difference in operating cost for comparable capability.

Heavy-duty and diesel shops run on tighter margins than people outside the industry realize. Labor efficiency, parts margin, and overhead control are what separate profitable shops from ones that are busy but broke. Overpaying for software because you didn't do the per-user math before signing is an entirely avoidable cost.

Know your headcount. Project 12 months. Compare the real number, not the marketing number. And don't sign an annual contract on a platform you haven't run a live job through.
