How Much Does an AI Chatbot Cost for a Small Business in 2026?
Real 2026 price ranges for a small-business AI chatbot: DIY tools, done-for-you setup and custom builds, plus the monthly costs and rules to know.
Short answer: in 2026 a small business can run an AI chatbot for anything from about €30 to €150 a month with a do-it-yourself tool. A done-for-you setup usually costs a few hundred to a few thousand euros once, plus a monthly fee. Fully custom builds from agencies often start around €10,000.
The rest of this post explains where those numbers come from, what you pay for every month, and how to check whether it makes sense for you. If you first want to know whether a chatbot is useful for your business at all, I wrote about that in where AI chatbots help and where they don't.
Three ways to get a chatbot
1. Do it yourself with a ready-made tool. You sign up, upload your FAQ or point the tool at your website, and paste a code snippet onto your site. Some examples of published prices, as of September 2026:
- Replai, a Slovak tool: from €30 a month, with a €100 one-time setup fee and a free basic version.
- Chatbase: from $40 a month (Hobby plan), $150 a month for Standard.
- Tidio's AI agent Lyro: from about $32.50 to $39 a month for 50 AI conversations, on top of a Tidio base plan.
- ManyChat, popular for Instagram and WhatsApp: Pro from $39 a month for up to 2,500 contacts.
- Intercom Fin: $0.99 per resolved conversation, with a minimum of 50 a month, on top of Intercom seats.
These are cheap to start. The hidden cost is your time: writing the answers, testing, fixing what the bot gets wrong.
2. Done-for-you setup. Someone like me sets up the bot on a proven platform, writes and tests the knowledge base with you, connects it to your booking or contact form, and keeps it working. On the Slovak market, simpler bots that answer from your documents start at about €400, and bots connected to a CRM or booking system run from the high hundreds into the thousands.
3. Fully custom. A bot built from scratch around your own systems. German agency guides from 2026 put custom development at roughly €10,000 to €30,000 for a first version, and more for large companies. For most small businesses this is more than they need.
| Option | Setup cost | Monthly cost | Good for |
|---|---|---|---|
| DIY tool | €0 to €100 plus your time | About €30 to €150, grows with volume | Simple FAQ, testing the idea |
| Done-for-you setup | About €400 to a few thousand | Platform, AI usage and care, tens to low hundreds of euros | Small businesses that want it set up properly, with booking or CRM |
| Fully custom | Often €10,000 and up | Hundreds of euros and up | Complex systems, large volumes |
What the monthly costs are made of
Whichever way you go, the monthly bill usually has three parts.
The platform. The subscription for the chatbot tool, the chat window, the inbox where you read conversations.
AI usage. The AI model is paid per amount of text it reads and writes. This is counted in tokens, small pieces of words. Small models are cheap: as of August 2026, OpenAI lists gpt-5-mini at $0.25 per million tokens read and $2 per million tokens written. For a typical small business bot, my rough math puts this at a few euros up to a few tens of euros a month. It grows with the number of conversations and with how much text the bot has to read each time.
Messaging channels. A chat window on your website costs nothing extra. WhatsApp is different. From 1 October 2026, Meta charges for replies to customers too, not only for marketing messages. Each business number gets 1,000 free service messages a month, and after that the price depends on the customer's country. In Meta partner 360dialog's published table, that is about $0.02 per message for Central and Eastern Europe, $0.03 for Italy and $0.055 for Germany. Most WhatsApp providers also add their own monthly fee.
What drives the price up or down
- Languages. Modern AI handles Slovak, German, English, Russian, Ukrainian or Italian well. Each language still needs testing, and your key answers should be checked by someone who speaks it.
- Integrations. Answering questions is the easy part. Booking an appointment, creating a contact in your CRM or checking an order means connecting systems, and that is where most of the setup time goes.
- WhatsApp and Instagram. Each extra channel adds setup work and, for WhatsApp, per-message costs.
- Size of your knowledge base. Ten pages of FAQ is quick. Five hundred products with prices that change every week needs a proper sync.
- Volume. More conversations mean more AI usage and often a higher platform plan.
GDPR and AI transparency basics
Two sets of rules matter here.
The EU AI Act. From 2 August 2026, people must be told when they are talking to an AI system, unless it is already obvious. In practice: the bot says it is a bot in its first message, and it never pretends to be a person.
GDPR. A chatbot collects personal data: names, phone numbers, whatever people type. So you need a line about it in your privacy notice, a data processing agreement with the chatbot provider, and a sensible rule for how long conversations are kept. The bot should not ask for sensitive data it doesn't need, like health details or ID numbers.
None of this is expensive. It just has to be done at the start, not after someone complains.
How to tell if it pays off
I won't give you a magic percentage, because it depends on your business. Here is a simple way to calculate it with your own numbers.
- Time saved. For one week, count the hours you or your staff spend answering questions that are already on your website. Multiply by four, then by what an hour of that time is worth to you.
- Enquiries you lose now. Count the messages that arrive in the evening or at the weekend and wait until the next working day. Estimate honestly how many of those people went elsewhere.
- Compare. Add the value of the saved time to the value of even a small share of those lost enquiries. Then compare it with the monthly cost, plus the setup cost spread over a year.
If the result is clearly positive, a chatbot has a real job to do. If it is close to zero, start with something smaller, like an automatic reply or a better contact form.
Where my offer sits

- A chatbot trained on your approved content: services, prices, process, FAQ.
- Answers in the languages your customers speak.
- Contact details saved and sent to you, or connected to your booking system or CRM.
- A clear handover to a real person, and a first message that says it is a bot.
- The accounts and data stay yours.
AI providers charge for usage. I show you those costs separately and upfront. You can read more about my AI and automation work, or tell me about your business and I'll give you an honest estimate.
FAQ
Does the chatbot speak Slovak, German or other languages?
Yes. It can answer in the languages your customers use, for example Slovak, English, German, Russian, Ukrainian or Italian. It usually replies in the language the customer writes in.
Can it book appointments?
Yes, if it is connected to your booking system or calendar. The customer picks a free time in the chat and gets a confirmation. This connection is part of the setup work.
What happens if it doesn't know the answer?
A well-set-up bot says it isn't sure, takes the customer's contact details and passes the question to you. It should not guess.
What does a chatbot cost per month?
For a small business, usually somewhere between €30 and €150 a month for the tool itself, plus AI usage and any WhatsApp message fees. With a done-for-you setup you also pay for care and updates.
Is WhatsApp more expensive than a website chat?
Usually yes. From 1 October 2026 Meta charges per message after the first 1,000 service messages each month, and the provider adds a fee. A website chat has no per-message charge from Meta.
