An HVAC company sells three different things, often on the same day. It sells labor, on a service call. It sells parts, off the truck, as part of that call. And many companies also sell items straight across a counter: filters to a property manager, a thermostat to a homeowner, a capacitor to another contractor who is short one. Most software is built for the first, tolerates the second, and ignores the third.
As of October 2026, "HVAC POS software" is a small but specific search, and the people making it usually have the same problem. Their service software schedules and invoices well, and they still cannot say how many 45/5 capacitors they own or what they made on parts last month. This guide explains what a point of sale does for an HVAC business, how it differs from invoicing software, and how to tell whether you need one.
What "POS" means when the store is a truck
In retail, a point of sale is the register. For a service company it is wider than that. It is the place where three things happen in a single action: an item is priced, payment is taken, and stock is reduced.
That third step is the one that separates a POS from an invoicing tool. An invoice says you charged $38 for a capacitor. A POS says you charged $38, the part cost you $9, it came off truck 3, and truck 3 now has two left. One is a record of the customer's bill. The other is a record of your business.
For HVAC that distinction is worth real money, because parts are a large share of many repair tickets and many shops never count them. A van can carry several thousand dollars of small parts, and it is common for an owner to have no reliable number for any of it. We covered the stocking side in HVAC truck stock, refrigerant, and parts management. The POS is what keeps those counts true after the first week.
The three kinds of sale an HVAC company makes
The service ticket. A no-cool call ends with a diagnostic fee, a part, and labor. This is the common case, and the requirement is speed: the tech needs to build the ticket from a catalog, not type it, and take payment in the driveway.
The counter sale. Someone walks in or calls ahead for filters, a thermostat, or a part. There is no appointment and no technician. A scheduling-first tool has nowhere to put this sale, so it ends up in a cash drawer or a handwritten receipt and never reaches the inventory count.
The equipment sale. A condenser, an air handler, a furnace. This is a large ticket with a deposit, an install date, and serial numbers that have to be recorded for warranty. It has more in common with a project than a repair, and it usually involves a deposit taken before the equipment is ordered. Our guide to customer deposits covers how to structure that.
A system that handles only the first leaves the other two in spreadsheets. The value of a true POS is that all three go through the same catalog, the same stock counts, and the same end-of-day report.
POS software versus invoicing software versus an FSM platform
These three categories overlap, and vendors use the words loosely. The practical differences look like this.
| Capability | Invoicing app | Scheduling-first FSM platform | Field-service POS |
|---|---|---|---|
| Itemized invoice from a catalog | Yes | Yes | Yes |
| Walk-in counter sale with no job | Awkward | Usually not supported | Yes |
| Stock reduced when an item is sold | No | Limited or an add-on | Yes, per truck and per location |
| Split payment across cash, card, and check | Rarely | Sometimes | Yes |
| Returns and refunds against stock | No | Limited | Yes |
| Barcode scanning | No | Rarely | Yes |
| Warranty records and lookup | No | Varies | Yes |
| Scheduling and dispatch | No | Yes, the core strength | Through an add-on calendar (GetTimePad, $199/month) |
The honest summary is that scheduling-first platforms are stronger at dispatch boards and weaker at the register. If your company's hardest problem is routing twelve technicians, dispatch should lead your decision. If your hardest problem is that parts and money do not reconcile, the POS should.
What an HVAC POS has to do well
Sell from a catalog. Every part you stock should exist as an item with a cost and a price. The tech picks it; they do not type it. This is also what makes pricing consistent between technicians. If you have not built a catalog yet, start with the service price book guide.
Count by location. The warehouse, the counter, and each truck need separate counts. "We have six" is useless if all six are on the truck that is across town. IntelliDrive's inventory counts and van transfers work this way.
Take every kind of payment. Payment links for cards, cash, check, and on-account for commercial customers, including splitting one ticket across two methods. IntelliDrive OS supports split payments across cash, check, on-account and a card payment link, and commercial customers can be billed on account. It takes cards through payment links rather than card-present hardware. See on-account billing for how to run that without letting receivables drift.
Record serials on equipment. Model and serial belong on the sale, tied to the customer. IntelliDrive creates a warranty record for every product sold; type the serial in the Serial # box on the equipment's line (the warranty keeps it), put the model in the sale's notes, and photograph the data plate into the customer's Photos & Documents tab. That is the foundation for HVAC warranty tracking.
Handle returns. A wrong part comes back, goes into stock, and the customer is refunded. If the software cannot put the part back on the shelf, your counts drift every time it happens.
Reorder before you run out. Reorder alerts (an opt-in, in-app notification when a part falls below its reorder point) and purchase orders close the loop, so the Monday supply-house run is driven by a list and not by whatever the techs remember.
Close the day. One report that shows sales by payment type, so the deposit matches the tickets. We described the routine in end-of-day close and cash reconciliation.
Maintenance season is where the counter earns its keep
Fall and spring tune-ups are the moment a POS pays for itself. A tune-up visit is a fixed-price service that frequently turns into a parts sale: a weak capacitor, a dirty flame sensor, a filter the customer has not changed in a year. Each of those is a small ticket that only happens if the part is on the truck and the price is in the catalog.
Maintenance agreements add a second kind of sale, the recurring one. IntelliDrive doesn't run agreements or recurring invoices — there is no contract, visit-schedule or auto-billing feature — so each agreement payment and each visit is rung up as its own sale, and the plan list lives in your own records. For how to run the season itself, see HVAC fall tune-up season scheduling and billing and HVAC invoicing software for maintenance contracts.
What it costs, and how the pricing model changes the answer
HVAC companies are usually quoted on a per-technician or per-user basis, and the number grows with the team. Per-technician systems such as ServiceTitan and per-user platforms such as Jobber scale their bill with headcount, and Housecall Pro and Workiz sell tiered plans, so what you pay depends on the plan and the team size.
IntelliDrive OS is $79/month flat for the whole business, billed monthly, with unlimited users. The first 30 days are free, with a card required at signup. The $79 includes every IntelliDrive feature, with no per-user fees and no feature tiers; GetTimePad scheduling and dispatch is a separate $199/month add-on. For a five-person HVAC shop, that is the difference between a software line you notice every month and one you do not. A side-by-side is on our ServiceTitan comparison page, and if you are weighing a per-user plan, the Jobber alternative breakdown is a good place to compare.
Card processing is a separate cost in every case. IntelliDrive OS integrates QuickBooks Payments, Square, and Stripe, so the rate you pay is the one you arrange with the processor.
Where IntelliDrive OS fits, and where it does not
IntelliDrive OS is a point of sale first. It has a full POS for in-shop and mobile use (it runs in the browser and can be installed to your phone's home screen), inventory counts by location and truck, barcode scanning, purchase orders, automatic warranty records for every product sold, and a one-way push of sales and payments to QuickBooks Online that you run when you want it. Cash sales keep working in an already-open app if the connection drops and sync when it returns; everything else, including payment links, needs a connection. Scheduling and dispatch run through GetTimePad, a separate $199/month add-on that adds a calendar, live GPS tracking, and ETA texts.
It is not an enterprise call-center platform. A company with forty technicians, a dedicated dispatch department, and a need for deep marketing attribution may be better served by a larger system and should budget accordingly. For a company of one to fifteen people that sells parts as well as time, a POS-centered system is usually the closer fit.
A one-week test before you commit
- Load fifty real items. Your most-used capacitors, contactors, filters, and one piece of equipment, each with cost and price.
- Set opening counts for one truck and the shop.
- Run every sale through it for a week, including counter sales.
- Count the truck on Friday. Compare the system count with the physical count. The gap is your shrinkage and your process problem, now visible.
- Run Reports → Sales grouped by product. It shows revenue, cost, profit and margin for each item, and for many owners it is the first time they have seen the number.
If the Friday count is close and the report is believable, the system works for your shop. If the count is far off, the software is not the issue; the habit of ringing up every part is. That is still worth knowing, and it is covered in inventory shrinkage and stock counts.
Common mistakes when an HVAC shop sets up a POS
Three setup mistakes account for most of the systems that get abandoned.
Loading the whole supplier catalog. A distributor price file has tens of thousands of lines. Importing all of it buries the two hundred items your technicians really use, and the search becomes useless. Load what is on your trucks today and add items as you buy them.
Leaving cost blank. It is tempting to enter only the selling price to get started. Without cost, there is no margin report, and the margin report is the main reason to do any of this. Enter cost from your last invoice for each part, even if it is approximate.
Letting "miscellaneous part" exist. If the catalog has a generic line that technicians can price freely, they will use it for everything, and stock will never move. Either remove it or require a note each time it is used, and review those notes weekly. Every one of them is a part that should be in the catalog.
A fourth, smaller point: decide who is allowed to discount. A counter sale to another contractor at a trade price is normal, but it should follow a written policy, not a judgment call at the register. IntelliDrive OS can restrict who is allowed to give discounts by role, but it has no built-in trade-price tiers, so write the trade discount down; the policy side is covered in discount controls and technician pricing authority.
The bottom line
An HVAC company that stocks parts is a retailer whether it thinks of itself as one or not. A POS is the tool that treats it that way: every item priced, every sale counted, every payment on the same ticket. Start with the parts you sell most, count one truck honestly, and let a week of real sales tell you whether the numbers hold.
