The cheapest start costs nothing: use a free AI assistant, plus the AI features built into software you have, on one repetitive task for two weeks. Only then pay for a single individual plan, about $5 to $20 a month, for the person who uses it most. Keep personal and client details out of free tools while you learn.
What makes a cheap start expensive is rarely the subscription. It's the hours lost trying five tools at once, and the risk of pasting a customer's or member's details into a free chat that may be used for training. One task, one tool and one rule about data cost less than any plan, and they tell you far more about whether AI suits your business.
Spend nothing for the first fortnight, on one task
The first two weeks are a test of the task, not of the tool. Pick something that meets four conditions:
- It happens at least weekly, so two weeks gives you several attempts.
- It's mostly writing or reading: replies, notices, summaries, descriptions. That's where free assistants are strongest.
- A mistake is cheap and visible. A clumsy newsletter paragraph gets caught; a wrong figure in an invoice might not.
- You can check it in under a minute, because checking is part of the cost.
Good first tasks include replies to common enquiries, a weekly notice or newsletter, meeting notes turned into actions, product or event descriptions, and rewriting a policy into plain language. Poor first tasks include anything involving figures you'd have to verify line by line, and anything that needs someone's personal details to make sense.
Before you start, time the task the old way twice. Write the minutes down. Without that number, you'll finish the fortnight with an impression instead of a result.
AI features sitting unused in software you have
Many small businesses have paid for AI features without noticing. Check these before opening any new account:
| If you use | What's included | Good first use |
|---|---|---|
| Microsoft 365 business plans | Copilot Chat at no extra cost, which now works on Outlook mail and open files | Summarising a long email thread; drafting a reply from it |
| Google Workspace | Gemini built into the plans: Gemini in Gmail and the Gemini app on Business Starter; Gemini across Gmail, Docs, Sheets, Slides, Meet and Drive on Standard and above | Drafting in Gmail; tidying a document |
| Gmail | "Help me write", which can match the tone of your past emails on Business Starter, Standard and Plus | Replies that sound like you |
| Shopify | Shopify Inbox's AI agent, which answers customers on its own on the Basic plan and above for stores with new customer accounts | Order and delivery questions |
| Xero | Smart Document Capture for receipts and bills, announced as free on all plans | Getting receipts into the books |
| Canva | AI features that draw on a monthly allowance | Social posts and posters |
The Microsoft one catches people out most often, because the paid Copilot licence gets the attention. What you get free in Copilot Chat compared with Microsoft 365 Copilot sets out the difference.

A church office's first month for $0
A church office makes a good test case, because its software budget is close to nothing. In this example, with invented but realistic figures, the office runs on one part-time administrator working 16 hours a week, with the minister and a handful of volunteers. The church already uses Google Workspace through a non-profit programme, which includes the Gemini app at no extra cost. The administrator logged three weekly jobs for two weeks before trying anything:
- The weekly notice sheet: 90 minutes.
- Hall-hire enquiries: about 20 a week, at 4 minutes each, so 80 minutes.
- Rota reminders to volunteers: 45 minutes.
That's 215 minutes a week, a fifth of the administrator's paid time.
Hall-hire replies: the prompt, the result and the fix
The administrator wrote one reusable prompt containing the hire terms and pasted each enquiry under it:
You help a church office reply to hall-hire enquiries. Use only the
hire terms below. If an enquiry asks about anything the terms don't
cover, say the administrator will confirm. Under 120 words, friendly,
plain English, no promises beyond the terms.
Hire terms: main hall seats 80; kitchen included; $25 an hour on
weekdays, $35 an hour at weekends; minimum 2 hours; $50 deposit,
returned after the hall is checked; no alcohol without committee
permission; all events finish by 10pm.
Enquiry: "Hi, could we book the hall for my son's 7th birthday on
Saturday the 14th, 2-5pm, about 40 people? Can we bring a bouncy
castle? Is there parking?"The first illustrative reply:
Hi [first name], thanks for thinking of us! The main hall would suit 40 guests well. On a Saturday it's $35 an hour, so 2 to 5pm would be $105, plus a $50 deposit that's returned after the hall is checked. The kitchen is included. A bouncy castle should be fine as long as it's used on the hall floor. There's parking for around 20 cars behind the church. Just let me know and I'll pencil you in!
The price is right: three hours at $35 is $105, plus the deposit. Two sentences are wrong. The terms say nothing about inflatables, so the reply should have said the administrator would confirm; instead it granted permission. And the parking detail is invented: the church has no car park. The fix took two minutes. The administrator added "Parking: none on site; street parking nearby" and "Inflatables: only with the committee's written permission and the hirer's own insurance" to the terms, and ran the prompt again. The second reply was correct. After that, each enquiry took about two minutes including a read-through.
Rota reminders: before and after
The old reminder went to everyone at once:
Dear all, please find attached the rota for October. Please check your dates and let me know if there are any problems. Many thanks.
Half the volunteers never opened the attachment. The administrator pasted the rota table into the assistant (first names and dates only) and asked for one short message per volunteer. A typical result:
Hi [first name], you're on the rota for Sunday 5 October (welcome desk, 9:45am) and Sunday 19 October (coffee after the 10:30 service). If you can't make a date, reply by Wednesday 1 October and I'll find a swap. Thank you!
The administrator checked each message against the rota, which took a few seconds apiece, and sent them from the office account. Missed slots dropped, and the job fell from 45 minutes to about 20.
The month's numbers
| Task | Before (minutes a week) | After, including checking |
|---|---|---|
| Notice sheet | 90 | 45 |
| Hall-hire replies | 80 | 40 |
| Rota reminders | 45 | 20 |
| Total | 215 | 105 |
That frees 110 minutes a week, roughly eight hours a month, for $0. The administrator's hours didn't change; the freed time went on the backlog of hall invoices and the out-of-date events page. The minister's only new rule was that nothing pastoral or personal goes into the assistant: no names from the prayer list, no notes from visits.
The cheapest route for three other kinds of organisation
The same principle, one task with tools you have, lands differently depending on the software an organisation runs on. Three quick sketches:
A toy shop selling through Shopify. The free starting point is inside the admin. Shopify Inbox's AI agent can take the "where's my parcel?" and "is this suitable for a three-year-old?" questions, provided the delivery, returns and age-guidance pages are clear enough for it to answer from. Sidekick, Shopify's built-in assistant, is included with Shopify plans (its features and limits vary by plan) and can draft product descriptions. The owner's first fortnight costs nothing, and the only spend worth considering later is an individual assistant plan for the pre-Christmas rush of new stock.
A charity shop with no office software. Many shops run on a till, a phone and a volunteer rota on paper. The cheapest route is a free assistant on the manager's phone, used for two jobs: turning a volunteer's notes and photos into an online listing with a title inside eBay's 80-character limit, and writing the weekly volunteer notice. If the parent charity qualifies for Google Workspace for Nonprofits, the Gemini app comes with it at no extra cost. The one rule to set on day one: no donor names, addresses or phone numbers in prompts.
A members' club on Microsoft 365. The club already has Copilot Chat through its business plan. The committee secretary's best first task is turning a long email thread about a fixtures dispute into a one-paragraph summary with the decisions still open, then drafting the reply. The paid Microsoft 365 Copilot licence, at $21 a user a month on annual billing, only earns its place if someone needs it to reason across mail, meetings and files together, and a club secretary rarely does in the first month.
Three free-tier habits that end up costly
A free start stays free only if you avoid these.
1. Pasting personal details into consumer chats. Free and individual plans can use your chats to improve their models unless you switch that off in the privacy or data settings, and switching it off doesn't make a consumer account suitable for other people's personal information. Business plans don't train on business content by default. Until you're on one, write prompts with placeholders like [first name] and fill the details in afterwards. If staff are already doing otherwise, whether free ChatGPT is good enough to run a business on explains where the free plan's limits sit.
2. Automating before the task is stable. Free automation tiers look generous and burn out quietly. Zapier's Free plan gives 100 tasks a month on two-step Zaps that check for new data every 15 minutes. Make's free plan gives 1,000 credits a month, but each scheduled check uses a credit even when nothing has arrived, so a scenario polling every 15 minutes uses about 2,880 credits a month on its own and runs out long before the month ends. Automate a task only after you've done it by hand with AI enough times to know the steps.
3. Tool-hopping. Trying ChatGPT on Monday, Claude on Tuesday and Gemini on Wednesday feels like research, but it means rewriting your instructions three times and never learning one tool's habits. They're all capable at everyday writing. Pick one for the fortnight; switch only if it clearly fails your task.
One smaller point on free plans: OpenAI says ads may appear on ChatGPT's Free and Go plans, while Plus and above have none. That doesn't change what the assistant can do, but it's worth knowing if you're choosing a plan staff will use all day.
The first $20: when to pay, and for whom
Pay when one person hits the free plan's limits in the course of real work, more than once a week, on the task you've already proved. That's the signal: not a feature list, but a limit getting in the way. The free limits themselves change often, so judge by what you run into rather than by published caps.
Pay for one person first, the heaviest user, on an individual plan. As of September 2026 the options are roughly:
- Google AI Plus at $4.99 a month, or Google AI Pro at $19.99.
- ChatGPT Go at $8 a month, or ChatGPT Plus at $20.
- Claude Pro at $20 a month, or $17 a month billed annually.
- Microsoft 365 Premium at $19.99 a month for someone on a personal Microsoft account; it replaced Copilot Pro, which is no longer sold, and includes the Office apps plus Copilot for the subscription owner.
The sum is quick. A $20 plan pays for itself if it saves about an hour and a half a month for someone whose time is worth $15 an hour. Take a toy shop owner who writes product descriptions with the free plan and keeps hitting the limit in November: if the paid plan saves three hours in that month alone, it has covered two months' fees. Bill monthly while you're proving it, so you can cancel in a quiet season.
Before a second person gets a paid seat, write down what the first person does with it: the prompts that work, the checks they make. A shared page of working prompts costs nothing and makes the second seat productive from its first day; how to build a shared prompt library shows a simple format.
Team plans, two-seat minimums and non-profit prices
Team plans add shared Projects, admin controls and business data terms, and they come with minimums that matter to small organisations:
| Plan | Standard price | Minimum | Non-profit route |
|---|---|---|---|
| ChatGPT Business | $25 a seat monthly, $20 annually | 2 seats | OpenAI for Nonprofits: $8 a seat annually, $10 monthly |
| Claude Team | $25 a seat monthly, $20 annually | 2 seats | Claude for Nonprofits: Team at $8 a seat |
| Google Workspace | About $7 a user a month on Business Starter, annual plan | Priced per user | Workspace for Nonprofits includes the Gemini app and Gemini Notebook at no extra cost |
| Microsoft 365 Copilot Business | $21 a user a month, annual | Annual commitment only; up to 300 seats | Microsoft's non-profit Copilot add-on is $25.50, more than the commercial price |
Two points stand out. A one-person business pays for two seats on ChatGPT Business or Claude Team, about $40 to $50 a month, so an individual plan is usually the cheaper start. And non-profit pricing isn't always lower: Microsoft's non-profit Copilot add-on costs more than the commercial Copilot Business licence, so compare before assuming the charity route wins. Eligibility for every programme varies; check the criteria for your organisation before planning around a price.
A members' club committee of three shows the choice. If only the secretary drafts anything, one $20 individual plan does the job. If all three need to work from the same instructions and files, a two-seat team plan plus sharing costs about the same as three individual plans and keeps club documents under business terms.
Automation comes last, not first
Automation connects tools so work moves without anyone copying and pasting. It's where AI saves the most time and where cheap starts go wrong most often, because an automated mistake repeats itself until someone notices.
The order that keeps costs down: do the task by hand with AI until the steps stop changing, write the steps down, then automate the dullest step first. In the church office, that might eventually mean a two-step Zap that copies each hall-hire enquiry email into a sheet, so the administrator can paste the day's batch into the assistant in one go. On Zapier's Free plan, at 20 enquiries a week, that's around 87 tasks a month, which fits inside the 100-task allowance. At 30 a week it doesn't. Having the reply drafted automatically is a further step again: Zapier's AI steps are only on Professional and above. Either change is the moment to decide whether the time saved justifies a paid plan.
If you're unsure which of your tasks would stand up to automation, free AI tools against paid plans helps you decide where money should go first.
Tracking whether the free month worked
At the end of the fortnight, or the month, fill in four numbers for your task: minutes before, minutes after including checking, number of times the AI output needed a real correction, and any mistake that reached a customer or member. Then apply a simple rule:
- Time fell by a third or more, and nothing wrong reached anyone: keep going, and add a second task.
- Time fell, but corrections are frequent: improve the prompt (add the missing facts, as the church office did with parking) and run another fortnight.
- Time barely moved: the task may not suit AI, or the prompt is doing too little. Try a different task before spending anything.
- You hit the free limits on a task that works: that's the moment to buy the first individual plan.
The church office's month met the first rule on all three tasks. Its next step wasn't a subscription at all; it was adding the monthly magazine as a fourth task, still for $0.
Questions about starting with AI on no budget
Is a free AI chat account safe for business use?
For drafting that contains no personal or confidential details, generally yes, once you switch off the setting that lets your chats be used for model training. Consumer plans let you do that in their privacy or data settings. For anything involving customers, members or staff by name, use a business plan, which does not train on business content by default, or leave those details out of the prompt.
Do I need a paid Copilot licence to use AI in Outlook?
Not to start. Microsoft 365 business plans include Copilot Chat at no extra cost, and it now works on Outlook mail and open files. The paid licence, Microsoft 365 Copilot Business at $21 a user a month on annual billing, adds reasoning across your emails, meetings and files together. Try the free Copilot Chat on your real tasks before paying for the upgrade.
What is the cheapest paid AI option for a one-person business?
An individual plan. Google AI Plus is $4.99 a month, ChatGPT Go $8 (ads may appear on Go), and ChatGPT Plus or Claude Pro $20. Team plans such as ChatGPT Business and Claude Team need at least two seats, so a sole trader would pay about $40 to $50 a month for features built for sharing with colleagues.
Can a church or charity get AI tools free or discounted?
Often, if it qualifies. Google Workspace for Nonprofits includes the Gemini app and Gemini Notebook at no extra cost. OpenAI for Nonprofits prices ChatGPT Business seats at $8 a user a month on annual billing, and Claude for Nonprofits offers Team at $8 a user a month with a two-seat minimum. Eligibility rules vary, so check each programme's criteria before planning around the price.
