ChatGPT for small business: what to use it for, and what not to

By · - Which plan to pay for, the one setting to change on day one, the jobs it does well for a service business, and three real cases that show where the line is.

The short answer

Use ChatGPT to write first drafts, rewrite things in plainer words, summarize long documents and think a decision through. Don't use it as the final word on anything a customer will rely on: prices, policies, legal or medical answers, or facts about a real person. For one owner, the $20 Plus plan with model training turned off is enough. Once two or more people share customer details in it, the Business plan is the safer choice.

What people actually use it for

The best data on this comes from OpenAI's own economists, working with Harvard's David Deming, who classified a large sample of real ChatGPT conversations for a National Bureau of Economic Research paper in September 2025. Three topics, practical guidance, seeking information and writing, made up nearly 80 percent of all conversations. Writing was the most common work task. Non-work use grew faster, rising from 53 percent of messages to more than 70.

That matches what we see running client work every day. ChatGPT is a writing and thinking tool first. It's very good at turning a messy idea into a clean paragraph, and much less reliable as a source of facts it hasn't been given. Plan around that and most of the risk goes away.

Which plan to pay for

OpenAI's plans, as listed on its pricing page in US dollars:

PriceUsed to train models by default?Who it suits
Free$0Yes, unless you turn it offTrying it out
Go$8/mo in the USYes, unless you turn it offLight use, more room than Free
Plus$20/moYes, unless you turn it offAn owner working alone
Business$25 per user/mo, or $20 billed annually; two-seat minimumNoTwo or more people sharing customer or staff details

The training column is the one that matters. On the personal plans, OpenAI's help centre says data sharing is on by default; you turn it off under Settings, Data controls, "Improve the model for everyone." On ChatGPT Business, business data is excluded from training by default. Business has a two-seat minimum, so the smallest annual workspace is $40 a month. For a clinic or a salon with a front desk, that's a small price for not having to explain later where a client's notes went.

Jobs it does well

These are the jobs where a wrong first draft costs you a minute of editing, not a customer.

  • First drafts of emails you put off. The polite no to a supplier, the reminder about an unpaid invoice, the note to a client whose appointment you had to move
  • Review replies. Paste the review, say what actually happened, ask for three short versions. Pick one and fix the details. Our review reply templates are a good starting brief
  • Rewriting your own pages. Your service descriptions, written the way you'd say them to a customer at the counter
  • Summarizing long documents. A supplier contract, a lease, a 40-page government guide. Ask what it says about the three things you care about, then read those clauses yourself
  • Staff checklists. Talk through how you open the shop; it turns that into a numbered list someone else can follow
  • Spreadsheet formulas. Describe the column you want, get the formula, test it on five rows
  • A second opinion before a decision. Lay out the options and ask it to argue against the one you're leaning toward

Each of these starts with something you know and asks ChatGPT to shape it. That's where it's strongest. The longer version of this, for marketing specifically, is in our guide to using AI for small business marketing.

Three cases that show where the line is

One from a Canadian tribunal, one from a US court and one from Canada's privacy regulators.

The chatbot that set a refund policy. Air Canada's website chatbot told a grieving customer, Jake Moffatt, he could buy a full-fare ticket and claim the bereavement discount afterwards. The airline's actual policy said otherwise. Air Canada argued the chatbot was responsible for its own words. In February 2024, British Columbia's Civil Resolution Tribunal disagreed and ordered the airline to pay $812.02 in damages, interest and fees. It wasn't ChatGPT, and the amount was small. The principle is the expensive part: if AI writes it on your website, you said it.

The cases that didn't exist. In 2023 two New York lawyers filed a brief citing six court decisions ChatGPT had invented. The judge in Mata v. Avianca fined them and their firm $5,000 and made them write to every judge falsely named as an author. Web search, which OpenAI has since added, helps. ChatGPT still produces confident, specific answers that are wrong, and it doesn't flag which ones.

The privacy finding. In May 2026, the federal privacy commissioner and its counterparts in Quebec, British Columbia and Alberta found that OpenAI's early training of ChatGPT didn't comply with federal and provincial privacy laws, and that users weren't told clearly enough that answers could be inaccurate. OpenAI has since made changes. The point for you is narrower. The regulators' principles for generative AI put the obligation on any organization using these tools, not only on the companies building them. A client's health notes pasted into a personal account with training switched on is your responsibility, not only OpenAI's.

What to keep out of it

  • Anything you'd need a client's permission to share: health details, card numbers, home addresses, staff files
  • Final answers to customers on prices, refunds, warranties or policies. Draft with it, then check every number against your own price list
  • Legal, tax or medical answers you'll pass on to a client as yours
  • Facts about a named person, including reviewers and competitors
  • Anything that publishes without a person reading it first

The last one matters most. A wrong draft that you read costs nothing. The same draft sent automatically is where all three cases above started.

Twenty minutes of setup that pays back

Do this once and every answer gets better.

  • Turn off model training under Data controls if you're on Free, Go or Plus
  • Fill in the custom instructions with the facts it keeps getting wrong: your services, your prices, your hours, your city, and the words you'd never use
  • Make a separate project for each recurring job, such as review replies, the monthly newsletter and staff documents, so the context stays with the job
  • Keep a short checklist beside the keyboard: names, numbers, dates and promises get checked before anything leaves

Where we fit, and when you don't need us

We use ChatGPT and Claude every working day. AI drafts, our people edit and decide, and nothing reaches your customers until you approve it from your phone. Social is $1,000 a month for nine pieces of content, and the rest of our lines and prices are on the pricing page. The content and social page shows what a month of it looks like.

Here's the honest limit. If you like writing, have four spare hours a week and mostly need help getting started, the $20 plan and the setup above will cover much of the writing you'd otherwise pay for. That's a real answer. What ChatGPT won't do is notice that you haven't posted in three weeks, or film the reel. If the hours are what you're short of, that's the part to hand off.

A different question entirely is whether ChatGPT mentions your business when customers ask it for a recommendation. That's covered in how to get ChatGPT to recommend your business.
