AI phone answering for small businesses: a plain guide

8 September 2026 Β· 5 min read Β· by the NordTell team

Small businesses lose calls for a boring reason: the person who should answer is busy doing the work. The plumber is under a sink. The dentist is with a patient. The owner is driving to the next job. AI phone answering is a way to pick up anyway. This guide explains what it does, how to set it up in an afternoon, what it costs, and what to keep an eye on. No jargon, and nothing you need a developer for.

Who this is for

You do not need a call centre to have a phone problem. You need one phone and two hands that are often busy. If any of these sound familiar, keep reading.

  • You return calls in the evening, from a list you scribbled during the day.
  • Your voicemail is full of half messages with no number.
  • Customers say "I tried to call you" and you believe them.
  • The same five questions arrive by phone every day: hours, prices, directions, availability, "do you do this".
  • You have thought about hiring a receptionist, and the sums did not work for the hours you would actually need.

If none of them apply, you are probably fine. A phone answered by a person who knows the business is still the best option there is. This is for when that person is not available.

What it can take off your plate

An AI receptionist is a program that answers the phone, talks with the caller, and acts. It greets people with your business name and says it is an AI. Then it handles the routine: it answers questions from material you gave it, books and moves appointments through your calendar, takes a proper message with a name and a number, and passes urgent calls to you or a colleague. When it does not know something, it says so and offers a callback instead of guessing.

It does not replace your judgement. Anything unusual, angry or delicate should reach a person. The trick is that most calls are not unusual, so the person gets interrupted a few times a day instead of twenty.

Setting it up in an afternoon

Block three hours. You will not need all of them, but you will want to play.

  1. Write the instructions. Imagine briefing a temp on their first morning: who you are, what you do, what to say to the five common requests, and what never to promise. Plain sentences work best. Here is how to write them.
  2. Pick a voice and a language. Choose the language your callers use, and a voice you would be happy to hear on your own line. NordTell has safety nets built in for thirteen languages, listed under languages.
  3. Test it in the browser. Talk to it with your microphone. Try to break it: mumble, change your mind, ask for something you do not offer. Fix the instructions and try again.
  4. Give it your material. Upload the price list, the FAQ page, the opening hours. It quotes from these and says when it does not know. See knowledge.
  5. Set the escape routes. Your mobile for a warm transfer, and a message when nobody picks up. An agent that always has a way to a person is an agent callers forgive.
  6. Connect a number. Buy one inside the product or bring the one you already have. Then forward your phone to it when you are busy, or all the time. See Bring your own phone number.

What it costs

NordTell charges for minutes of talk time, not for seats or agents. The bill is calls times length. A small business with a handful of calls a day usually fits the smallest package: Launch is €29 a month with 60 minutes included, and extra minutes cost €0.50 each. There is no setup fee and no per-agent fee, and a free account lets you build and test in the browser before you pay anything. Real calls need a package.

Before you pick a size, count. Calls per week, times the average length in minutes, times four. That is your monthly need. This post walks through the sum, and the full list of packages is on the pricing page.

What to watch in the first month

Three things. Honesty: listen to ten calls and check that the agent never claimed something it did not do. Consent: decide whether calls are recorded, and whether the caller is asked first. Rules on recording differ between countries in Europe, so check with your own adviser; this post explains the principle. Drift: callers will ask things you did not think of. Add each new question to the material, and the agent gets better every week.

A short first-week routine: read every summary; listen to any call marked as transferred or unsure; add each new question to the knowledge base; check minutes used against the package; ask three customers how the call felt. Half an hour a day for one week is enough, and after that a glance at the summaries each morning will do.

Where NordTell fits

NordTell is built for exactly this size of business: one agent, one number, instructions in plain words, and every feature in every package. It runs on servers in the EU and is built in Copenhagen. You can build and test for free, and pay for minutes only once a real number is connected.
