How to set up an AI receptionist in one afternoon (step by step)

Most of the work in setting up an AI receptionist is not technical. It is deciding what your business actually says. Budget one afternoon, uninterrupted, ideally with a coffee and the person who answers the phone most often.

Here is the order that works.

Before you touch anything: gather four things

Open a blank note and write down:

1. Your services, in the words customers use, not your internal names. "Whitening", not "in-office peroxide protocol". 2. Your prices, or the honest version of them. "From 45 EUR" is fine. "It depends" is not — replace it with what it depends on. 3. Your hours, including the split if you close at midday, and what happens on public holidays. 4. The eight questions you are sick of answering. Parking. Card payments. How long it takes. Whether you come to them. Cancellation policy. Whether you take children. Languages you speak. How far you travel.

If you get this note right, everything after it takes twenty minutes. If you skip it, you will spend the whole afternoon fighting with the software instead of thinking about your business.

Step 1: create the business (5 minutes)

Name, type of business, city, main language. The language matters more than people expect: it sets the default voice and tone for every reply. If you serve two languages routinely, pick your primary one — the receptionist can still answer in others.

Step 2: fill the Business Brain (60 to 90 minutes)

This is the real work, and it is where the quality comes from. You are typing that note in, section by section: description, services, hours, prices, FAQs, policies.

Two pieces of advice from watching a lot of people do this:

• Write like you talk. The AI copies your register. If you write stiff corporate sentences, it will answer in stiff corporate sentences.
• Answer the awkward things explicitly. "We do not offer emergency appointments." "We do not treat under-12s." "We do not travel outside the province." Every gap you leave is a place where a customer gets a vague answer.

You do not need to finish everything in one go. Get the description, services, hours and five FAQs in, and you already have something usable.

Step 3: set the rules (10 minutes)

This is the section people rush and then regret. You are telling the receptionist how to behave:

• Never invent a price. If it is not written down, say so and offer to pass the request on.
• Always ask for a name and phone number before finishing.
• Escalate complaints immediately rather than trying to resolve them.
• Keep answers short — two or three sentences on the phone.

Short and explicit beats long and clever. Four clear rules are followed better than fourteen fuzzy ones.

Step 4: test it privately (30 minutes)

Do not connect the phone yet. Open the test chat and interrogate your own receptionist like a difficult customer:

• Ask a price you deliberately never entered. It should admit it does not know. If it invents a number, fix your rules.
• Ask "are you open on Sunday?" and check the answer against reality.
• Ask something completely outside your business — "do you sell tyres?" — and see whether it stays in character.
• Ask in another language if you serve one.
• Try the annoying real question: "how much for the thing my neighbour had done?"

You will find three or four gaps. Fix them in the Brain, retest. This loop is the difference between a receptionist that sounds like your business and one that sounds like a chatbot.

Step 5: connect one channel (15 minutes)

Start with the lowest-risk channel, which is almost always web chat or WhatsApp. Watch the first ten real conversations. Read the transcripts.

Only then connect the phone number. Voice is less forgiving: people interrupt, background noise happens, and a wrong answer spoken aloud feels worse than a wrong answer typed. Go there second, once the Brain has been through real questions.

Step 6: read the transcripts for a week

This is the step that separates a setup that improves from one that stagnates. Every day for a week, read what people actually asked. You will discover that customers ask about things you never thought to write down — where to park the van, whether you invoice companies, whether the treatment hurts.

Add each one to the FAQs. After a week the receptionist stops being surprised.

The four mistakes that cause 90% of the problems

• Vague prices. Leads to hedged answers and lost bookings.
• No escalation rule. The AI tries to handle a complaint and makes it worse.
• Going straight to phone. Errors are much more expensive out loud.
• Never reading the transcripts. You lose the only feedback loop that exists.

What "done" looks like

You should be able to hand your phone to a stranger, have them ask your ten most common questions, and hear answers you would have given yourself. Not perfect answers — yours.

That is one afternoon. You can start building the Business Brain now and test it before anyone else hears it.
