Every pricing page for an AI receptionist shows a monthly number, and almost none of them show the number you will actually pay. This guide explains the cost structure so you can compare any two quotes, including ours, on the same basis.
The three parts of the cost
The build. Someone has to design the call flow, write the triage questions in your words, connect the calendar and the CRM, set up the number, and test it against real calls until it handles them well. That is skilled work and it happens once. With a subscription product the build is partly you, following a setup wizard. With a built-for-you system it is a fixed, quoted fee.
Running costs. Every minute of a call uses telephony, speech recognition, a language model, and a synthetic voice. At current provider list prices those add up to cents per minute. A five-minute call that ends in a booked job costs less than a dollar to run. The question is who bills you for those minutes and at what markup.
Changes over time. Your hours change, a service is added, the calendar moves from one tool to another. Someone has to update the assistant. Some vendors include this, some charge per change, some sell a monthly plan.
The two pricing models
Subscription. A monthly seat that includes a block of minutes, then overage per minute above it. Integrations and extra features sit in higher tiers. Simple to start, and the cost rises with volume, which means it rises in your busy season. You do not own the phone number, the recordings, or the configuration; if you stop paying, they stop existing.
Built for you, owned by you. A one-off build fee, then running costs billed by the providers directly to accounts in your name. No per-call markup, because you are not renting a seat. The build is more upfront and the running cost is lower per minute, so the crossover arrives at fairly modest call volume. If you part ways with the builder, the system keeps running; it is yours.
We do the second one. The build fee is quoted after a short call, because it depends on how many call flows you need and what the calendar and CRM connections involve, and we put the running cost per minute in writing with it.
The number that matters: cost per booked job
Monthly fee against monthly fee is the wrong comparison, because the two options do different things with a call.
Work it out like this:
- Calls you currently miss in a month. Your phone system or carrier report has this.
- The share of those that were new customers who would have booked. Half is a conservative starting point.
- Your average job value.
Multiply the three and you have the monthly revenue currently leaking. The missed-call calculator does this from your own numbers and adds the quotes that go cold for lack of follow-up. Then compare the total cost of each option, build plus a year of running costs, against a year of that leak. For most service businesses with meaningful call volume the payback is measured in weeks, and the difference between the two pricing models is smaller than the difference between having one and not.
What drives the build cost up or down
- Number of call flows. One flow for "book a service visit" is the base. Separate flows for emergencies, existing-customer questions, and sales enquiries add scope.
- Calendar and CRM. GoHighLevel, HubSpot, Jobber, Housecall Pro, ServiceTitan, Google Calendar and Cal.com are routine. A custom or legacy system takes longer.
- Languages. Spanish alongside English is common and adds testing time more than build time.
- Hand-off rules. Warm transfer to an on-call person, text and callback, or a booked callback slot. Each is a defined path to test.
- Volume of testing. We test against recordings of your real calls before it handles live ones. More call types, more testing.
What does not change the price: the number of calls it answers. Once built, it answers one or one hundred at once for the same build fee, and only the per-minute running cost scales.
Questions that expose hidden pricing
Ask any vendor these and write the answers down.
- What is the cost at twice my current call volume?
- Is there a per-call or per-minute markup on top of provider costs?
- Are calendar and CRM connections included, or a tier?
- What does a change to the script cost, and how fast does it happen?
- Who owns the phone number, the recordings, the transcripts, and the configuration?
- What happens to all of that if I cancel?
A clear answer to number five is worth more than a low monthly number. Losing your business phone number when you switch vendors is the most expensive line item nobody puts on a pricing page.
Where the answering service sits in this
For comparison, a human answering service bills per call or per minute with a monthly minimum, and the message it produces still needs a callback before there is a booking. We wrote up the full comparison in AI receptionist vs answering service. At low volume it can be the cheaper choice. Past a few hundred calls a month it rarely is, and it never books the job on the first call.
Getting a number for your business
Fifteen minutes on a call, with your call log open, and you leave with the build fee, the running cost per minute, and the payback arithmetic on one page. If the numbers do not work for your volume we will say so, because a system that does not pay for itself is not one we want to have built.
