HVAC Billing Software: Three Different Bills, One System
HVAC billing software has three jobs: the driveway service call, the financed changeout, and the maintenance plan. What handles all three, and what it costs.
An HVAC shop does not have a billing problem. It has three.
There is the $109 diagnostic that should be paid before the truck leaves the driveway. There is the $12,000 changeout, which involves a deposit, ordered equipment, sometimes a lender, and a final payment that arrives whenever the homeowner gets around to it. And there is the maintenance agreement book, hundreds of small charges on a schedule, sold once and billed forever. Three different transactions, three different failure modes, and most of the software ranking for "HVAC billing software" handles exactly one of them well. Usually the small one.
What HVAC billing software actually has to do
Walk through the three bills and the requirements write themselves.
The service call. The whole game is speed. The invoice gets built at the truck from the flat-rate code and the parts used, the customer taps a card or a payment link, done. If your flat-rate book lives in a binder and the invoice gets written Sunday night, you are not billing, you are doing homework; we made the case for repair codes in flat-rate pricing for small shops. Every day between finished work and sent invoice costs you twice, once in collection odds and once in cash. Cutting collection time from 45 days to 15 handed the example shop in our DSO breakdown about $75,000 in working cash. That money comes from billing mechanics, not from working harder.
The changeout. Full system replacements mostly land between $7,500 and $15,500 now, and plenty run past $20,000. Nobody pays that like a service call. The bill becomes a sequence: a deposit when the equipment is ordered, the balance at startup, and increasingly a lender in the middle. Both Jobber and Housecall Pro solved the lender part the same way, by wiring Wisetack into their estimates. The customer applies from the estimate, you get paid in full within a few days, and the flat cost to you is 3.9% of the financed amount on jobs from $500 to $25,000. That fee stings until you price it in, and then it reads differently: 3.9% to close a $14,000 job that was about to die on the kitchen table is the cheapest sales tool you own.
The agreement book. Recurring billing is where generic invoice apps quietly give up. Two hundred agreements billed monthly means two hundred charges that should run themselves against cards on file, renew on schedule, and never involve a human unless a card bounces. If any part of that loop is manual, the plan book you built for stability becomes a monthly clerical tax. The revenue side of that trade-off is covered in our maintenance agreement playbook; the billing side is simply automation or nothing.
A shop that bills three ways and buys software that handles one has not bought billing software. It has bought a receipt printer for its smallest ticket.
The HVAC billing software you can buy, priced
The vendors' own pages dominate this search term, so read them the way you read a supplier's spec sheet, for what is gated, not what is promised.
- Jobber puts invoicing and card payments on the $29-a-month Core plan (billed annually up front; $49 month to month), and that part is genuinely cheap. But automatic payment collection, the card-on-file billing your agreement book depends on, waits until the Grow plan at $149 a month annual. QuickBooks sync starts a tier below that, on Connect. Card processing runs 2.9% plus 30 cents, ACH 1%.
- Housecall Pro starts at $59 a month annual, with card rates advertised from 2.59%. Recurring service plans and the QuickBooks sync both arrive at the Essentials tier, $149 a month annual. Same shape as Jobber: the entry price bills service calls, the real price bills your business.
- FieldEdge and ServiceTitan own the deep end. Both are demo-and-sales-call products with no published pricing, built around an office that has a person who owns billing as a job. ServiceTitan in particular is priced for the 30-truck operation; we covered what that means for small shops in ServiceTitan alternatives.
Notice the pattern in the first two. The number on the billboard covers bill number one. Bills two and three, the ones that actually move a shop's cash position, sit around $149 a month at both vendors. That is not a scandal, but it should change which column of the pricing page you compare.
One more gate to check before you sign anything: where the QuickBooks sync sits and what it carries. A billing system that cannot land its invoices and payments in your books cleanly just relocates the clerical work to January. We wrote a whole piece on what an HVAC invoicing sync has to push to QuickBooks, and every test in it applies here.
Billing all three without a back office
This is the gap FieldCommerce was built into. A 1 to 8 truck shop runs all three bills with no billing clerk, so the software has to close each loop itself. Invoicing and payments drafts the service-call invoice from what the tech logged and takes the card in the driveway. Changeouts carry a deposit and a balance on one job record instead of two disconnected invoices. Agreements bill the card on file on schedule and flag the bounces, which is the only part of recurring billing that deserves your attention. And none of it is held behind a higher tier; the pricing is published and the billing loop ships whole.
Here is the audit worth running this week. Pull ten finished jobs from last month and write down two dates for each: work done, money in the bank. If the gap on service calls is more than a day, bill one is broken. If a changeout took three phone calls to collect, bill two is. If you know an agreement lapsed only because the customer called to cancel, bill three has been broken for a while.
