How small businesses use AI: a practical starter guide

By Infinithink Studio · October 19, 2026

How small businesses use AI looks very different from the headlines. It's rarely robots or big projects. It's a shop owner drafting review replies in minutes, an accountant drafting client emails from bullet points, a small agency writing first drafts of every post.

Adoption is still early. In 2025, 20% of EU businesses with ten or more employees used at least one AI technology, and 17% of small ones, according to Eurostat. Among those that use it, marketing and sales is the most common purpose. If you haven't started, you're not late. You're in the majority, and you can learn from the mistakes others have already made.

This guide covers where to start, the first five tasks to hand over, what it really costs, how to measure the time you save, the mistakes to avoid and when to get help.

Where to start

Block one hour. Write down the tasks that ate your time last week. Then mark the ones that tick four boxes:

• Repetitive. You do it every week, in a similar way.
• Mostly text. Emails, posts, descriptions, summaries, documents.
• Low risk. A mistake is easy to spot and cheap to fix.
• Measurable. You can time it before and after.

Start with two or three of those. Leave anything involving money, contracts, health or legal advice for later, and keep a person in charge of it when you get there.

How small businesses use AI: the first five tasks

1. Emails and replies

Paste the customer's message, say what you want to answer in three bullet points, and ask for a reply in your tone. You check and send. An email reply generator is built for exactly this.

Reply to this customer email [paste]. Points to make: the order ships Thursday, we've added a 10% discount code for the delay, they can call us on the number in our signature. Friendly, under 100 words.

2. Content

Social posts, newsletters, blog drafts, product descriptions. Give the facts, the audience and the length. Save your tone once so every draft starts closer to your style. Tools such as the business post for social media and the product description generator ask for exactly those inputs.

3. Review replies

Answer every Google review, good and bad, within a day. AI drafts, you personalize one line and publish. For negative reviews, apologize for the experience without admitting fault, and invite the customer to contact you directly. Try it with the review response generator.

4. Summaries

Meeting notes, long email threads, supplier contracts, recorded calls. Ask for a summary with the decisions, the open questions and who does what. For audio, transcribe first, then summarize. The text summarizer handles the written part, and AI voice and transcription turns a recorded call into text.

5. Internal documents

Job ads, onboarding checklists, procedures, price-list updates. These are the documents nobody has time to write, and AI gets you to a usable first draft quickly. A job description generator is a good place to start.

Each task follows the same rhythm. You give context, AI drafts, you check. The checking is not optional.

What it really costs

The subscription is the smallest part of the bill. Plan for four costs.

• Software. Free plans exist and are fine for testing. For daily work, expect a monthly fee per person for a single assistant, so check the current price before you commit. On Infinithink, the Free plan gives you 150 credits a month. From there the full suite grows with you, Lite €12, Starter €39, Pro €89, Business €199 and Agency €399 a month, all final prices with nothing added at checkout. Business comes with 10 team seats and Agency with 25, each on one shared credit pool, and yearly plans give you 2 months free (€120, €390, €890, €1,990 and €3,990 a year).
• Setup time. A few hours to write your best prompts, save your tone and agree on rules.
• Review time. Every draft needs a read. Count it, or your savings will look better on paper than in real life.
• Training. One session for the team. Under Article 4 of the EU AI Act (Regulation (EU) 2024/1689), organisations that use AI systems take measures to ensure sufficient AI literacy among their staff, and a short training is a step in that direction.

Compare per person and per team. A per-seat assistant for three people can cost more than a team plan, or less, depending on what's included. You can see what each Infinithink plan includes on the pricing page.

How to measure the time saved

Skip the vague promises and measure it yourself. It takes two weeks.

1. Pick three tasks from your list.
2. Time them without AI, for one week or from last week's memory. Note how often each one happens.
3. Time them with AI for two weeks, including the time to check and fix the draft.
4. Calculate. Minutes saved per task, times how often it happens, gives minutes saved per week.
5. Check quality too. How many drafts needed big changes? Any errors that reached a customer?

A simple table is enough. Copy it into a spreadsheet and fill it in as you go:

If a task doesn't save time after two weeks, drop it and try another. Not every task is worth handing over.

A one-week plan to get started

• Day 1. Make the task list and pick three tasks. Time them as you do them.
• Day 2. Open a Free account on one or two tools. Write one prompt for each task and save it.
• Day 3. Write down your tone of voice in five lines: who you write to, formal or informal, words you use, words you never use, one example you like. Save it in the tool.
• Day 4. Do the three tasks with AI. Time them again, review included.
• Day 5. Write one page of rules for the team: what AI is for, what never goes in, who checks before anything is sent.
• Day 6. Show one colleague how you do it, using your saved prompts.
• Day 7. Look at the times. Keep what saved time, fix what didn't, pick the next task.

Run this plan for one week, then keep timing the tasks for two more. By the end of week three you'll know what AI is worth to your business, in minutes and in quality, before you pay for a bigger plan.

Mistakes to avoid

• Pasting sensitive data into personal accounts. Use a business plan with clear data terms, and agree on what never goes in, such as health data or passwords.
• Publishing without a read. AI makes confident mistakes. A person signs off.
• Too many tools. One workspace the team actually uses beats five that nobody remembers.
• No shared rules. Write one page: what it's for, what's off limits, who checks.
• Expecting AI to know your business. Give it your facts, your prices, your tone. It only knows what you tell it.
• Measuring nothing. Without numbers you can't tell what to keep.
• Forgetting the legal basics. Under Article 50 of the EU AI Act, people who chat with an AI system should be told so, unless it's obvious. The GDPR applies to the customer personal data you paste in. Check your own case with a professional.

When to get help

Do it yourself if one or two people will use AI for writing and replies. Get help when you want several people working the same way or a chatbot on your site, and nobody on the team has the time. A few hours with someone who has done it before, to write the shared prompts, set the rules and train the team, can spare you months of trial and error.

Frequently asked questions

How can a small business use AI?

Start with repetitive text tasks, such as customer emails, review replies, social posts, product descriptions and summaries. AI drafts, a person checks and sends.

What is the best AI for a small business?

One the whole team will use, with a business plan, clear data terms and the models that suit your tasks. Test two options on three real tasks before deciding.

How much does AI cost for a small business?

From free for testing to a monthly fee per person for a single assistant. Multi-model platforms like Infinithink have a Free plan with 150 credits a month, then start at €12 a month for one user (Lite). Team seats come with Business, at €199 a month for up to 10 people, and Agency, at €399 a month for up to 25. Prices are final, nothing is added at checkout. Add setup and review time to the bill.

Is it safe to use AI with customer data?

It depends on the provider and its terms. Check in the official documentation whether data is used for training and whether a data processing agreement is available. Set rules on what can be pasted in and never include data you don't need.

Do I need technical skills to use AI?

No, not for writing, replies and summaries. Connecting AI to other software, or putting a chatbot on your site, usually needs some setup help.

How soon will I see results?

Measure after two weeks of daily use. That's enough to see which tasks save time and which don't.

Which tasks should a small business not hand to AI?

Anything where a mistake is costly or personal: final prices and contracts, legal or medical advice, decisions about hiring or firing, and replies to a customer who's angry or upset. AI can help you prepare, by summarizing the facts or drafting options, but a person decides and signs.
