What does an AI agent cost, and what should it be allowed to do?
Two separate numbers: what it costs to build, and what it costs to keep answering. Most quotes only mention the first.
The short answer
An AI agent is built as part of a system rather than sold alone, so it sits inside a build starting at $2,000 over 30 to 45 days. Running it is a separate, ongoing cost you pay directly to the providers: voice minutes, message volume and model usage, billed to your own accounts. An agent answering an inbound call and handing it to a person is the case that pays for itself soonest.
SHT-02What drives the number
Two numbers, and only one of them is a project fee
The build is a one-off: wiring the agent to your phone line or inbox, teaching it your rules, connecting it to the system that holds the lead, and testing it against calls that go wrong. The running cost is per-minute for voice, per-message for chat, and per-token for the model, and it is billed to your own accounts rather than through the studio. That is deliberate: the invoices arrive in your name, the access is yours, and no part of the system is rented through me. A quote that gives you only the build number is hiding the half you will pay every month.
What the agent is actually for
The whole design is the handoff. On an inbound call the agent answers, works out whether the conversation was real, finds the lead by the caller's number, and puts a notification in front of a human while the lead is still warm. It does not replace the person. It buys back the calls that went to voicemail at 7pm, which is a smaller claim than most vendors make and a checkable one: count how many inbound calls you missed last month.
Where the payback is, and where it is not
The economics turn on your average ticket, not on a percentage anyone can quote you. In a business where a single booked consultation is worth several hundred dollars or more, an agent that books one extra a week justifies itself immediately — and you can test that against your own numbers rather than against a claim on this page. In a business with a low ticket and high call volume, the honest answer is that a good booking form and a follow-up sequence usually cost less and do more.
The limits, stated up front
There is no accuracy percentage on this page, because there is no figure worth defending. What can be shown is the code that decides what counts as a real conversation, and the failure each rule was written after. The agent classifies, routes and notifies. Moving a job forward, sending an estimate or taking a deposit is a deliberate action by a person — a design decision rather than a limitation waiting to be removed. And AI does not belong in every system: one of the three systems in production has none on purpose, because both AI features it inherited were removed after one of them reported work it had not done.
SHT-03The options, side by side
What each route actually costs you.
| Option | Price | Timeline | The trade-off |
|---|---|---|---|
| Do nothing | $0 | — | The after-hours calls go to voicemail. Count last month's missed calls and multiply by your average ticket; that is the number this decision is actually about. |
| Answering service | Monthly retainer | Days | A human takes a message. Nothing is written into your system, so the follow-up still depends on somebody reading a note. |
| Off-the-shelf AI receptionist | Monthly subscription | Days | Fast to start and genuinely useful. It answers into its own product, so the lead lands somewhere that is not your system and the handoff is a notification rather than a record. |
| Agent built into your own system | Part of a build from $2,000, plus provider usage | 30-45 days | The lead becomes a record on the board your team already works from. Costs more up front and takes longer, and is only worth it if there is a system on the other end. |
SHT-04General notes
The questions people actually ask.
- N01How much does an AI agent cost for a small business?
- The build sits inside a system starting at $2,000 over 30 to 45 days; agents are not sold as a standalone product because one answering into nothing is a toy. Running it is separate and ongoing — voice minutes, message volume and model usage, billed to your own provider accounts rather than through the studio.
- N02Will it replace my receptionist?
- No, and it is not built to. The entire design is the handoff: answer, work out whether the conversation was real, and get a human in front of the lead while it is still warm. The outbound dialler is the same idea from the other end — a person talks, the software keeps the record.
- N03How accurate is it?
- No number is published, because there is not one worth defending and an invented one is easy. What can be shown is the code that decides what counts as a real conversation, and the failure that each rule was written after. It gets tested against your own real calls in the first days rather than promised in advance.
- N04Can the agent send an estimate or take a deposit on its own?
- No, it is not wired to. Agents classify, route and notify. Moving a project forward, sending an estimate or accepting money is a deliberate human action. That is a design decision, not a limitation waiting to be lifted.
- N05Do I need a CRM first?
- Practically, yes — the handoff works because there is something on the other end holding the lead, the estimate and the schedule. You can start with the agent, but the route the record takes gets designed on day one either way.
- N06Does it work in Russian and Spanish?
- Yes. The studio works directly in English and Russian, and multilingual intake is a normal part of a build. The language your customers hear and the language your staff works in are separate choices and do not have to match.
