Your AI receptionist break-even point is one number: the monthly fee divided by the gross profit on your average job. If the answer is one or two booked jobs a month — and for most garage door shops it is — the service only has to save a couple of calls you'd otherwise lose to pay for itself.
Here's the formula, the numbers to plug in, and the mistakes that make shops think the math is worse than it is.
Break-even jobs = monthly cost ÷ gross profit per average job.
Two inputs, one division. An example:
Gross profit per job: $350 × 0.50 = $175. Break-even: $297 ÷ $175 = 1.7 jobs per month.
So the service needs to put fewer than two extra jobs on your board each month to break even. Everything past that is profit. If your average ticket is bigger — spring pairs, opener installs, double-car doors — the number drops below one.
Run the same formula with your real ticket and your real margin. It takes two minutes, and it beats any sales pitch.
This is where shops talk themselves out of good math. The only jobs that count are the ones you would have missed without the service:
Jobs you'd have booked anyway don't count. If your CSR already answers every call during business hours, those calls aren't part of the break-even math — the AI only earns its fee on the calls that were slipping through.
That's also why the honest question isn't "is it worth it" in the abstract. It's "how many calls am I actually missing?" — the starting point for the full break-even analysis. Count your missed calls for two weeks. Most owners who actually log them are surprised by the number, and almost always in the same direction.
Say you run a one-truck shop. You miss about five calls a week — you're the tech, the dispatcher, and the receptionist. That's roughly 20 missed calls a month.
Not every missed call was a job. Say a third of them were real service opportunities, and you'd have booked half of those: about 3 lost jobs a month. At $175 gross profit each, that's $525 a month in lost profit against a $297 fee.
Break-even needs 1.7 jobs. Reality was losing 3. The service doesn't need to create demand — it just has to catch what was already falling.
If the test shows you're one saved job a month away from covering the fee, the risk is asymmetric: the downside is capped at one month's fee, the upside runs every month after. And if your volume is so low that even one saved job is a stretch, read when an AI receptionist is not worth it before you buy — the honest answer cuts both ways.
Finding your AI receptionist break-even point takes two inputs and five minutes: your average gross profit per job, and a rough count of missed calls. If the missed-call count covers the break-even number with room to spare, the decision is made. If it doesn't, wait and recheck in a busy season.
Either way, put the number on paper. A break-even you calculated beats a pitch you heard.
