AI for small business: where to start, and what it costs

Small businesses are behind on AI, and the gap is widening. In the US Census Bureau's Business Trends and Outlook Survey, published in May 2026, 19.8% of businesses said they had used AI in the past two weeks. Among firms with 250 or more employees it was 37%. Among firms with four or fewer, it was less than 20%. Between December 2025 and May 2026, use rose among firms with 20 or more employees and didn't change significantly among smaller ones.

Trying AI is a different matter. In the US Chamber of Commerce's 2025 small business report, 58% of small businesses said they use generative AI, up from 40% a year earlier. The two surveys ask different questions, so the numbers don't subtract neatly. Read together, they describe owners who have tried AI, in businesses that haven't built it into their week.

When businesses explain why they haven't started, know-how comes up far more often than doubt. In the EU, where the statistics office asks, 71% of companies that considered AI and didn't adopt it gave lack of relevant expertise as a reason. Only 21% said it wasn't useful to them (Eurostat, 2025 data).

The five steps below close that gap without a big project.

Step 1: Pick five tasks that come up every week

A good first task for AI has five things in common:

• It comes up every week, often several times.
• It's mostly reading or writing: emails, quotes, summaries, posts.
• You have examples of it done well, so the AI can copy what good looks like.
• A person can check the result in a minute or two before it goes out.
• A mistake is easy to spot and cheap to fix.

Leave for later anything that goes out without a person checking it, and anything that depends on numbers nobody trusts yet.

These are the tasks we'd usually start with:

Write down how long each task takes today. You'll need that number in step 5.

Step 2: Check the AI you already pay for

Many small businesses already pay for AI without using it.

• Google Workspace. Since January 2025, Google has included its AI in Workspace Business and Enterprise plans, with no add-on to buy. When it made the change, the Business Standard plan went from $12 to $14 a user a month.
• Microsoft 365. Microsoft includes a basic AI chat at no extra cost with eligible Microsoft 365 plans. Its fuller AI add-on for business users costs $21 a user a month on a yearly plan, currently discounted to $18, or $25.20 month to month.
• A separate AI subscription. If neither is enough, a business plan from one of the big AI chat apps costs about $20 a person a month billed yearly, or $25 billed monthly.

Whichever you use, buy business plans rather than personal ones. The major providers' business terms say they don't train their AI on business customers' data by default, and an admin can control who has access. Before adding anything new, check whether the AI in your current plan can do the five tasks from step 1, and what you could cancel.

Step 3: Write down the rules before anyone starts

Two short documents do most of the work.

A one-page AI policy for your team. It names the tools people may use for company work and lists what must never be pasted in. That list covers customers' personal details unless the tool is approved for them, passwords and card numbers, and anything a contract says must stay private. It also says who checks work before it goes out. Our guide to writing an AI policy covers each line.

A rulebook for the AI. One short document with your prices and where they're kept, your tone of voice and the words you avoid, and your policies on things like refunds and opening hours. It also says what the AI must never share and who approves what. In our experience, most wrong answers come from missing facts: nobody told the AI your prices or your refund policy. The rulebook gives it those facts every time.

Step 4: Save one assistant per task, and test it on real work

An assistant here means saved instructions for one task: what it's for, your rulebook, a few examples of the task done well, and the checks to run before a person sees the result. Business AI subscriptions let you save these in a shared project, so everyone uses the same version and a change happens in one place.

Test each assistant on three real examples before anyone relies on it, such as three customer emails it must answer correctly or three quotes that must match your price list. When it gets something wrong, fix the instructions or the rulebook as well as the draft, so the mistake doesn't come back.

Keep a person between the AI and your customers. Drafts go to someone who checks them and sends them.

Step 5: Measure the hours before and after

Pick one number per task, such as hours a week spent on quotes, the time it takes to answer an inquiry, or posts published a month. You wrote it down in step 1. Check it again after 30 days.

If a number hasn't moved, look at the assistant's instructions and examples first, then at whether people are using it. Give one person the job of looking after the assistants and the rulebook, with a monthly review in their calendar.

What it costs

Doing it yourself costs the subscription and your team's time. Outside help ranges from a few hundred dollars for a written plan to tens of thousands for custom builds. These are prices firms publish on their own websites, checked on October 23, 2026:

For comparison, our own prices are on our pricing page: an AI plan in one week for $750 for teams of up to 25 people, and an AI setup in two weeks from $3,000. In every case the AI subscription is extra, paid straight to the provider.

Whoever you talk to, ask for four things in writing: a fixed price, the tests that decide when the work is done, whose accounts everything is set up in, and what keeps working if you stop paying them.

Frequently asked questions

What's the best AI tool for a small business?

Often the one already in your office suite. Google Workspace business plans include AI, and eligible Microsoft 365 plans include a basic AI chat. Add a separate business subscription only for the tasks those can't handle.

How much does AI cost a small business?

The software usually costs between nothing and about $25 a person a month. Outside help ranges from a few hundred dollars for a written plan to tens of thousands for custom builds, as the published prices above show.

Is it safe to put customer information into AI?

Only on a business plan whose terms say your data isn't used to train the AI, and only the information your AI policy allows. Keep passwords, card numbers and anything a contract says is private out entirely.

How long does it take to get a team using AI?

With a clear list of tasks, a few weeks: about one to plan and two to set up and test five assistants. Most of that time goes into writing the rulebook and testing on real work.

Do I need an AI consultant?

Not if someone on your team has the time to work through the five steps above. Outside help is worth paying for when nobody does, when you handle sensitive client information, or when you want it done in weeks rather than months.
