Small businesses get sold the same AI advice as enterprises, which is useless when you have no IT department, no budget for a pilot, and no time to run one.
Here is the version that assumes you are the owner, doing this yourself, this week.
Short version: one $20/month subscription, used for writing and summarising, will cover most of what a small business actually needs. Everything beyond that is optimisation.
Start here, not with a strategy
The highest-return uses for a small business, in order:
- Customer emails and quotes. Draft faster, sound more consistent, stop rewriting the same explanation.
- Marketing copy. Product descriptions, social posts, newsletters — see ChatGPT for marketing.
- Summarising the boring stuff. Supplier contracts, long threads, forms.
- Turning notes into documents. Quotes, proposals, policies, job ads.
- Bookkeeping-adjacent text, not the numbers. Chasing letters, payment reminders, categorisation notes.
Note what is not on the list: automating your customer support, building a custom model, or "AI strategy." Those are for later, or never.
Which one to buy
You need one, not three.
- Mostly writing that customers read → Claude. Its output needs the least editing, which is the only saving that matters when you are doing it yourself.
- Mostly research, or you live in Gmail and Docs → Gemini. Live search plus native Workspace access.
- You want the most tutorials and the biggest ecosystem → ChatGPT.
- You genuinely do all three → a plan that includes several models, so you are not paying twice.
Can you get away with the free tier?
Often, yes — and you should try before paying.
Free tiers cap how many messages you get with the good model, then quietly move you to a weaker one. If you use AI a few times a week, you may never notice. If you use it daily, you will hit the ceiling mid-task, which is the worst moment.
The tipping point is not a message count. It is the first time a cap interrupts something that mattered.
Running two free tiers in parallel — Gemini plus one other — stretches this further than most people realise.
The mistakes that cost small businesses money
Buying seats nobody opens. The most common waste in this category. Buy one seat, prove it works, then add more.
Publishing AI output unedited. Customers can tell, and the damage is to trust, which is your main asset when you are small.
Automating too early. Use it manually for a month before wiring it into anything.
Pasting sensitive material into a free tier. Customer lists, contracts, anything under NDA. Free tiers commonly train on what you send.
Paying for the largest model for simple tasks. Reformatting a list does not need a flagship model.
What it actually costs
About $20 per month for one person. At that price it pays for itself if it saves you roughly twenty minutes a month, which it will in the first week.
The real cost is not the subscription — it is the time spent fixing bad output, which is why picking a model that writes well matters more than the price difference between them, which is zero anyway.
A realistic first month
- Week 1: use it for every customer email you write. Nothing else.
- Week 2: add one recurring document — quotes, or your newsletter.
- Week 3: start pasting in long things you would otherwise skim.
- Week 4: decide honestly whether it saved you time. If not, stop.
No integration, no automation, no strategy deck. If it does not help in a chat window, it will not help wired into anything.
Common questions
What is the best AI tool for a small business? One general assistant. Claude if you mostly write for customers, Gemini if you mostly research or live in Google Workspace.
How much should a small business spend on AI? Start at about $20/month for one person. Do not scale until that one seat is demonstrably saving time.
Can I run my business on the free version? For light use, yes. You will hit message caps if you use it daily.
Is it safe to use AI for customer emails? Yes, as long as a person reads before sending and you avoid pasting sensitive customer data into a free tier.
Do I need someone technical to set this up? No. If you can use a chat window and a web browser, you can do everything on this list.
Should I build a custom AI for my business? Almost certainly not. Custom builds make sense with proprietary data and high volume — a much smaller set of companies than the people selling them imply.
