An HVAC company on ServiceTitan has four accounting problems a general bookkeeper has never seen: a cash cycle that peaks in July and starves in October, maintenance agreements that are a liability rather than income, equipment that gets costed like a capacitor, and a blended P&L that hides which half of the business is carrying the other. We do this every day.
A retail store sells a thing, collects the money, and books the income. That is the business model your bookkeeper was trained on, and it is not yours.
You sell an $11,000 system in July that is partly financed by a lender who will remit in three weeks, net of a dealer fee. You bought the equipment on 30-day terms in June, so the bill comes due after the money arrives but before the shoulder season. The install crew is paid on performance and the spiff is split among the technicians who did the work. You also sold that customer a $199 maintenance plan, which is cash today and a promise of two visits you have not yet performed. Every single one of those facts has an accounting consequence, and ServiceTitan will not book any of them for you.
ServiceTitan is field service management software. In the standard setup it has no general ledger: QuickBooks is the book of record, and ServiceTitan pushes invoices, payments, adjustments and bills across through batch export. It does that faithfully, which is exactly the problem. Whatever your configuration says, right or wrong, gets written into your books every night with perfect consistency. Read how the ServiceTitan and QuickBooks integration actually works if you want that mechanism spelled out.
The result is an HVAC P&L that looks plausible and tells you almost nothing. Income is overstated by the maintenance plans you have not performed. Card processing costs are invisible. Install and service are blended into one gross margin that describes neither. And in the year of your life when you most need to know whether growth is helping, you have a number you cannot defend. This page is about fixing that specifically for HVAC shops on ServiceTitan. For the rest of the ecosystem, start at the ServiceTitan resource hub.
None of these are exotic. They are just specific to a trade that most bookkeepers have never worked in and a platform most bookkeepers have never opened.
Your best revenue month and your worst cash month can be ninety days apart. Equipment bought on terms, financing that remits late, performance pay on a record month and a shoulder season with the same fixed overhead will do that. A bookkeeper who does not model it will hand you a great July P&L and no warning about October.
A $199 annual plan is not $199 of income. It is mostly a promise of future work. It belongs on the balance sheet until the visits are performed, and ServiceTitan is well documented for getting this wrong on its own. For a shop with two thousand members, this is not a rounding error.
A condenser and a run capacitor should not be costed the same way. Equipment cost can be excluded from job costing by design, and a wrong price on one vendor bill permanently shifts the weighted average cost of a part SKU. Your material cost per install is either real or it is decorative.
Install runs at a fraction of the margin service does. One blended gross margin averages a low-margin, high-volume business with a high-margin, low-volume one and produces a number that describes neither. You cannot price, staff or grow on a blend.
Pay-by-performance, spiffs split among the technicians who performed the work rather than the one who sold it, and overlapping pay rules that can pay a technician on both rules at once. Labor cost also reports $0.00 when a technician has no hourly rate configured. See ServiceTitan technician commissions.
A callback on an install you already booked at full margin is real cost against revenue you already recognized. If callbacks are not costed back to the original job, your install margin is systematically overstated and you will never know which crew is expensive.

This is the conversation we have with more HVAC owners than any other, usually in the fall, usually with a note of panic in it. July was the best month in company history. October is terrifying. Both facts are true and they are causally linked.
Say you invoice $340,000 in July. The P&L, if you squint, looks fantastic. Now follow the actual cash.
Then revenue halves. The trucks, the leases, the dispatchers, the office, the software subscriptions and the salaried staff cost exactly what they cost in July. Fixed overhead does not know it is October. Meanwhile the June and July equipment bills are hitting, the performance pay has been paid out, and the maintenance visits you owe are being performed at a cost with no matching invoice.
That is the mechanism. It is not bad luck and it is not a bad month. It is the ordinary shape of an HVAC cash cycle, and the only defense is knowing your fixed monthly burn, knowing what you actually owe in deferred service, and knowing how much of your summer revenue was financing and card volume that arrived light. All three of those come out of a set of books that is kept properly, which is what our ServiceTitan bookkeeping services deliver every month.
A two million dollar HVAC shop, same year, same data, read two ways. Illustrative numbers, but this pattern is so common it is almost boring. The blended view is not wrong. It is just useless.
| The question | What the blended P&L tells you | What the business unit view tells you |
|---|---|---|
| Revenue | $2,000,000. One number. | Install $1.2M, Service $600K, Plans $200K earned |
| Gross margin | 38%. Looks healthy. Nothing to do here. | Install 28%, Service 58%, Plans 35% |
| Where the volume is | Not visible at all. | Install is 60% of revenue at the worst margin |
| Technician labor | One Wages Expense line on the P&L. | Costed to the job, install crews separated from service techs |
| Equipment cost | Buried in a single cost of goods sold total. | On the install job that actually consumed it |
| Who is carrying who | Impossible to say. | Service is quietly funding the install department |
| What you would do about it | Sell more of everything. Hire more of everyone. | Reprice install, or grow service and staff for it |
Seasonality is the one owners feel. These three are the ones that quietly corrupt the numbers underneath it.
When a homeowner buys a $199 annual plan with a spring and a fall visit, you have collected cash and taken on an obligation. Roughly half of that money is earned when you perform the spring visit and the other half in the fall. Until then it is deferred revenue, a liability, not income. ServiceTitan gets this wrong in specific, documented ways: a plan with two visits a year can recognize the full annual amount on each visit instead of half, and a dismissed recurring service event can permanently mis-recognize the deferred balance so that nothing ever comes back to correct it. Revenue can also land on the business unit that sold the membership rather than the one that performed the work, which quietly inflates your sales team and starves your service department. For a shop with two thousand members, this is a six-figure misstatement. The full mechanics are in ServiceTitan deferred revenue.
A condenser is serialized, expensive, ordered for a specific job, and often drop-shipped. A run capacitor is a consumable that lives on a truck. They should not be handled the same way, and in most files they are. Two things go wrong repeatedly. First, equipment cost and purchase order cost can be excluded from job costing by design, so your install job shows labor and parts but not the thing you actually installed, and the margin on that job is fiction. Second, on the parts side, a wrong price on a single vendor bill permanently shifts the weighted average cost of that SKU, and every job that consumes it afterward is mis-costed. Technicians can also mark materials as used without ever allocating them, in which case the cost is gone and no job ever carried it. More on this in ServiceTitan inventory and QuickBooks.
Labor is the largest controllable cost in an HVAC business and it is where ServiceTitan pay configuration causes the most damage. Overlapping pay rules can pay a technician on both rules for the same work. Spiffs are commonly split among the technicians who performed the job rather than the one who sold it, which changes who your top performer actually is. Labor cost reports $0.00 outright when a technician has no hourly rate configured, so that tech appears to be free. Labor burden double counts when the burden rate is set to include payroll costs already sitting in the account. And the job costing flyout locks once an invoice is posted and exported, so any payroll adjustment made afterward never reaches job cost at all. Every one of those distortions lands on your install margin, which is the number you use to decide whether to add a crew.

A flat monthly engagement. The full close, plus the HVAC-specific work a generalist would not know to do.
It begins with a free Audit of the real file, because we would rather show you what is broken than tell you what we sell.
We look at the actual numbers: your deferred revenue balance against the maintenance plans you have really sold, your Undeposited Funds balance and how old it is, whether merchant and dealer fees have ever been booked, whether install and service are separable at all, and how your technician labor is being costed. You get a written, honest read on what is wrong. No cost, no obligation, and the findings are yours to keep.
If two years of memberships were booked as income on sale and Undeposited Funds has been growing since 2023, we scope a one-time, fixed-price ServiceTitan QuickBooks cleanup and finish it. We do not start a monthly close on a foundation we know is broken.
Install, service, maintenance, and any other unit you run, set up so that revenue, technician labor, equipment cost and overhead land where they belong. This is what turns a blended 38% gross margin into three numbers you can actually manage.
Payment type mapping, a merchant clearing account, financing as its own payment type, batch export order so bills go before invoices, sales tax as a tax rate rather than an invoice line item, and the membership recognition setup. Next month should be easier than last month, not identical to it.
The full close, delivered on a schedule, with the deferred revenue roll, the unit margins and your fixed burn. You go into the shoulder season knowing exactly what it costs you and exactly how much service work you already owe. That is the whole point.
Send us your ServiceTitan setup and read access to your books. We will Audit them and come back with the numbers you cannot currently see: your real deferred revenue liability, your true install margin against your service margin, what card and dealer fees are actually costing you, and what your fixed burn is when the phones stop ringing.
Free, no obligation, and you keep the findings even if you never work with us.

You carry maintenance agreements that are a liability rather than income until the visits are performed, you sell high-value equipment on vendor terms, a large share of your revenue is financed or paid by card and arrives light and late, your technicians are paid on performance, and your revenue is seasonal while your overhead is not. A bookkeeper trained on retail or professional services will produce a tidy P&L that misses every one of those and tells you nothing useful about the business.
As deferred revenue. A $199 annual plan with a spring and a fall visit is mostly a promise of future work on the day it is sold. Roughly half is earned when you perform the spring visit and the other half in the fall. Until then it is a liability on the balance sheet, not income. ServiceTitan can get this wrong on its own, recognizing the full annual amount on each visit instead of half, or permanently mis-recognizing the balance when a recurring service event is dismissed, so the schedule has to be rebuilt and monitored rather than trusted.
Because your cash and your profit are on different calendars. The equipment for a record July was bought on 30 or 60 day terms in June and comes due in August. Card payments arrived net of processing fees and financing remitted late and net of a dealer fee, so the money that landed was less than the revenue you booked. Performance pay and spiffs on a record month are paid at the top of the cash curve. Then revenue halves in the shoulder season while fixed overhead does not move at all, and the maintenance visits you owe get performed at cost with no matching invoice.
The honest answer is that a single blended number is not a useful target, and chasing one is how shops make bad decisions. Install and service behave completely differently: install is typically high volume at a much lower margin, service is lower volume at a much higher one. A blended figure averages those two into a number that describes neither business. What matters is knowing your install margin, your service margin and your maintenance margin separately, and knowing which one is funding the others.
Usually because the equipment is not on it. Equipment cost and purchase order cost can be excluded from job costing by design, so an install job can show labor and parts but not the system you actually installed, which makes the margin on that job fiction. Labor is the other half of the problem: the job costing flyout locks once an invoice is posted and exported, so payroll adjustments made afterward never reach job cost, and labor cost reports $0.00 outright when a technician has no hourly rate configured.
We make sure they are recorded and costed to the right job and business unit, and we watch for the failure modes that make labor cost wrong. Overlapping pay rules can pay a technician on both rules for the same work. Spiffs are commonly split among the technicians who performed the job rather than the one who sold it, which changes who your real top performer is. Burden double counts when the burden rate includes payroll costs already sitting in the account.
Neither. You keep ServiceTitan and you keep QuickBooks, Online or Desktop. We work inside the stack you already run, remotely. What we replace is the assumption that the batch export is producing correct books. We fix the configuration so it stops writing errors, clean the history if it needs it, and close the month properly from then on.
Most of it, yes. The maintenance agreement deferred revenue, merchant fees, financing payouts, Undeposited Funds, technician pay rules and the business unit margin split are all common to any trade running ServiceTitan. What is most specific to HVAC is the severity of the seasonality and the equipment inventory problem. We work with plumbing, electrical, roofing and multi-trade home service companies on the same platform.
No. FinTruction is based in Coppell, Texas, and works remotely with HVAC and other home service companies across the United States. All of the ServiceTitan bookkeeping, cleanup and integration work is handled remotely. For everything else in the ecosystem, the ServiceTitan resource hub is the place to start.
Real results from contractors we have helped untangle their books and systems.
They didn’t just record transactions and call it a day. They built a custom chart of accounts around how a remodeling company actually runs, did a full catch-up on years of bookkeeping inside QuickBooks Online, and now stay on top of my monthly bookkeeping and payroll. Every step, they broke it down in simple terms instead of burying me in accountant talk.
FinTruction rebuilt the whole thing from the ground up, with real job costing, work in progress, and retainage. They didn’t just hand me reports and disappear; they walked me through my numbers until I understood them.
Sahil and his team handle the bookkeeping and job costing for my painting business. They cleaned up my books and set up integrations that give me accurate, timely job costing with solid weekly data. Reliable, detailed, and genuinely invested in getting the numbers right.
FinTruction is the only bookkeeping team we’ve found that truly understands construction accounting and WIP reporting. They aligned our income and costs across 21 jobs and gave us full, monthly transparency. Fast, accurate, and an indispensable partner.
When I came to FinTruction I had no financial structure. No job costing, no WIP tracking, books behind. They did a full cleanup and rebuilt job costing and WIP tracking in QuickBooks. Now I know what’s billed, what’s owed, and where every job stands.
