Running five trucks is the awkward size for an HVAC business. You’re too big for a paper schedule and a group text, but you’re nowhere near needing the enterprise systems the big contractors run. This is the guide for exactly that stage.
I have broken down what actually matters at five trucks, which systems fit that size honestly, and what you should expect to pay — including the pricing traps that catch owners at this stage.
Why Five Trucks is the Hardest Size to Manage
At one or two trucks, the dispatcher is the owner, and the schedule lives in your head. It works, barely.
At five trucks you’re running 15 to 25 jobs a day across three or four technicians, and the cracks show up fast:
- A tech calls because the job details in the text message didn’t include the gate code
- You double-book a slot because two people moved appointments
- An invoice sits unsent for a week because the paperwork got lost in the truck
- You don’t know which jobs are profitable until the month is already over
None of these are software problems on their own. Together they are. The system that fixes them doesn’t need to be the most powerful one on the market — it needs to fit your size without forcing you to pay for features designed for a 40-truck operation.
What actually Matters at Your Size
When you’re evaluating, weight these heavily. Everything else is a nice-to-have.
1. Scheduling you can see at a glance. A day view that shows every truck, every job, and every gap. If you can’t grasp your whole day in one screen, the tool will slow you down rather than speed you up.
2. Mobile app quality for techs. Your technicians decide whether the software works. If the app is clunky, slow, or needs signal to load a job’s details, they’ll go back to texting you — and you’ve paid for nothing. Offline mode matters more than you’d think: basements, crawlspaces, and rural jobs all kill signal.
3. Invoicing that leaves the truck. The single biggest cash-flow win at this size is invoicing from the job site instead of at the end of the week. Look for take-payment-on-site support.
4. Pricing that makes sense at five users. Most vendors price per user. At five seats, those monthly fees stack fast — check the per-user rate and whether there’s a tier that flattens out.
5. QuickBooks integration. You’re almost certainly already on QuickBooks. Either the software syncs properly or you’re doing double entry forever. Test this before you commit.
The Realistic Options For a Five-Truck Shop
Rather than pretend one tool wins for everyone, here’s how the market splits at your size.
Full-service platforms — built for growing HVAC companies, covering dispatch, invoicing, payments, and customer history in one place. These are the most common pick at five trucks because they scale with you to 20+. Expect to pay $150–$400/month at this size depending on the specific tools you enable. The trade-off is a learning curve — plan for two to three weeks of adjustment.
Lighter scheduling tools — cheaper, faster to set up, and genuinely good at calendar and job assignment. What they tend to lack is deep HVAC-specific features like maintenance agreements, equipment history, and technician performance tracking. Fine if you’re staying at five trucks. Frustrating if you plan to grow.
Field-service specific to trades — a middle ground, built for contractors generally rather than HVAC only. Usually the sweet spot on price, with enough HVAC-adjacent features to work.
The honest answer: at five trucks, most owners end up in the first category, because growing past five is usually the goal.
What it Actually Costs
Be careful here, because headline pricing rarely matches the bill.
| Cost element | Typical range | Watch out for |
|---|---|---|
| Monthly base | $50–$150 | Often quoted for 1–2 users only |
| Per additional user | $30–$80/mo each | This is where five trucks gets expensive |
| Setup/onboarding | $0–$1,000 | Sometimes mandatory |
| Payment processing | 2.5–3.5% per transaction | Hidden revenue line for the vendor |
| Annual vs monthly | Save 10–20% annually | Lock-in risk if it doesn’t fit |
The trap at your size: vendors advertise “starting at $49/month,” which is real — for two users. At five technicians you’re often looking at $250–$400/month once you add seats and enable payments. Always get a written quote for your team size before comparing.
One more: payment processing fees are where some vendors make more than they do on subscriptions. A 3% fee on $40,000/month in revenue is $1,200 — bigger than your software bill. Factor it in.
How to Choose Without Wasting Three Months
- Shortlist two, not five. Five evaluations will paralyse you. Pick the two that best fit your size and price.
- Run both in parallel for two weeks. Most offer trials. Have your actual dispatcher and one trusted tech use them on live jobs.
- Ask your technicians, not the dashboard. If the techs hate the mobile app, the software fails regardless of how good the office view looks.
- Test the QuickBooks sync before you buy. Not after. Ask support to walk you through a real sync.
- Get the five-user price in writing. Including processing fees and any mandatory onboarding.
Don’t let a vendor’s sales process rush you into an annual contract. If they won’t give you a real trial at your actual team size, that tells you something about the relationship you’re about to enter.
The Bottom Line
At five trucks, you’re not buying the most powerful software — you’re buying the one your technicians will actually use and that stops you from losing jobs and invoices in the gaps.
Prioritise the mobile app, the invoicing flow, and the true five-seat price. Everything else can be added later. Get those three right and the rest of the decision usually makes itself.
