The Short Answer
An AI receptionist has two kinds of cost: getting it set up, and running it every month. Off-the-shelf tools charge a monthly subscription and are cheap to start. A custom AI receptionist built for your business is a one-off project fee plus smaller running costs for hosting, the AI model and the messaging channel. As a reference, our focused AI builds typically range from $2,500 to $10,000, with receptionists that book appointments across several channels toward the upper end. Whether it is worth it depends on how many enquiries you miss today.
What an AI Receptionist Actually Does
An AI receptionist answers customers when your team cannot: after hours, during busy periods and on the channels customers prefer, such as WhatsApp, Instagram or your website. A good one answers questions from your own price list and policies, offers real free times from your calendar, books the appointment and passes the conversation to a person when it should. Our AI solutions page has a recorded demo of a WhatsApp receptionist doing exactly this.
The Costs, Item by Item
1. Setup or build
- Subscription tool: little or no setup fee. You configure it yourself from templates.
- Custom build: a project fee to connect the receptionist to your calendar, services and rules, test it and launch it. This is where most of the cost sits.
2. Monthly running costs
- AI model usage: charged by the volume of text processed. For a small business with a few hundred conversations a month this is usually a small line item.
- Messaging channel: WhatsApp Business Platform charges for some message types, mainly messages the business starts, such as reminders. Replies to customers who message you first are generally much cheaper or free. Check Meta's current rates for your country.
- Hosting and monitoring: the server that runs the receptionist and keeps a record of conversations.
- Subscription fee if you use an off-the-shelf tool. These often rise with the number of conversations, seats or channels.
3. Voice costs
A receptionist that answers phone calls adds a phone number, call minutes and speech processing. Voice is usually more expensive to run than chat for the same number of conversations, so many small businesses start with WhatsApp and website chat, then add voice once the value is proven.
4. Maintenance
Prices, services and opening hours change. Budget a little time each month to keep the receptionist's information current, or include it in a support plan.
Subscription or Custom?
- Choose a subscription if you mainly need to answer common questions and take messages, and your booking system is supported out of the box.
- Choose custom if it must book against your real calendar with your own rules, sell or take orders, work in WhatsApp in the language your customers write in, or hand over cleanly to staff.

Does It Pay for Itself? A Simple Check
Take three numbers from your own business:
- How many enquiries a month go unanswered or are answered too late.
- What share of answered enquiries usually turn into a booking or sale.
- What one booking or sale is worth to you.
Multiply them to get the value of the enquiries you are missing each month. If an AI receptionist recovers even part of that, compare it with the monthly running cost and the setup fee spread over a year. For many appointment businesses, a handful of extra bookings a month covers the running cost.
AI Receptionists for Medical and Dental Offices
Clinics have extra requirements: patient privacy, careful wording and a rule that the receptionist never gives clinical advice. These add some setup work but are standard in a well-built system. Our guide to AI receptionists for dental clinics covers this in detail, and salons and spas can read AI booking assistants for salons.
Frequently Asked Questions
How much does an AI receptionist cost for a small business?
Off-the-shelf tools are a monthly subscription. A custom AI receptionist is a one-off build plus running costs for hosting, the AI model and messaging. Our focused AI builds typically range from $2,500 to $10,000, with multi-channel booking receptionists toward the upper end.
Is a WhatsApp AI receptionist cheaper than a voice receptionist?
Usually, yes. Chat costs less to run per conversation than phone calls, which add call minutes and speech processing. Many businesses start with WhatsApp and add voice later.
Can an AI receptionist book appointments into my calendar?
Yes. A custom receptionist checks real availability for each staff member and service length, books the slot and sends confirmations, and the calendar prevents double bookings.
Will it replace my front desk staff?
No. It handles the messages your team cannot reach in time and passes anything unusual to a person, so staff spend less time on repeat questions.
