AI for small business owners: 7 jobs, 7 prompts, $20 a month

What should a small business owner use AI for?

A general chat subscription (Claude Pro is $20 a month, or $17 billed yearly, as of September 2026) finishes the first five of the seven jobs below end to end and gives you a first read on the last two, bookkeeping and contracts. The five single-purpose tools owners buy for the same jobs list at $182 a month together, priced on 27 September 2026, and only one of them, Jasper, does a job the chat plan also does completely. The prompts are the ones I paste; the last column says when to run one in a second model.

The bracketed parts are yours, and the two lines that matter most are the negative ones. "Do not invent a price" and "do not add requirements I did not give you" stop the model filling gaps with plausible numbers, which is the failure that costs an owner money. The US Small Business Administration's own guide puts the promise plainly: "AI can help your small businesses do more with less." Its next paragraph is the caution that anything you produce must not infringe a copyright or trademark, and that sensitive data should stay out of the prompt.

Three of the seven jobs have their own pages here with the full prompt and worked examples: an AI response to a bad review, how to politely decline an email, and using AI to clean up a spreadsheet for the export you are about to send your bookkeeper. If you also make the sales calls, AI for sales reps has ten prompts from account research to CRM notes. For the decisions behind the jobs, the business prompts pack has 20 more, from a one page plan to a 13 week cash flow check.

Is AI worth paying for in a small business?

Yes, at $20 a month, once you send more than about ten customer emails, quotes or replies a week; below that, my rule is that the free tiers cover you. The gap between saying and paying is wide. The US Chamber of Commerce's Empowering Small Business report (18 August 2025) found 58% of small businesses self-identified as using generative AI, up from 40% in 2024 and 23% in 2023. The JPMorganChase Institute, reading the actual payments of 4.6 million Chase business banking customers (published 14 April 2026), found 17.7% had paid an AI vendor from the business account by December 2025.

The two numbers are not a contradiction. Most of the 58% are on free tiers or a personal card, which the Institute's method cannot see. Its other finding is the one that decides the purchase: the typical entry cost fell from about $50 a month in 2019 to $20 to $30 a month in 2025, and "The 2025 cohort reached a 10 percent adoption rate in six months, compared to over six years for the 2019 cohort." Solo owners lag employer firms by ten points, 15.3% against 26.1%, and they are the ones with nobody to hand the emails to.

Which is the best AI for small business owners: a chat subscription or a dedicated tool?

A chat subscription first, then one dedicated tool for the job that touches money. I priced the five tools that come up when owners ask this question, against their own pricing pages on 27 September 2026, US list prices, monthly billing. Only Jasper sells a job the chat plan already does end to end. Buffer and HubSpot sell a writing feature bolted to something a chat cannot do (a scheduler, a contact database). QuickBooks and Jobber sell the ledger and the invoice, and a chat plan does not post either.

One of each is $182 a month billed monthly. That is the number to hold against a $20 chat plan: it removes Jasper, does the drafting half of Buffer and HubSpot, and leaves QuickBooks and Jobber untouched. Square, the other tool on every owner's counter, is not in the table because its point of sale software is free and it charges 2.6% plus 15 cents per in-person payment (3.3% plus 30 cents online) as of September 2026; no chat plan touches that job either. Canva and Otter, which sit on most page-one lists for design and meeting notes, are not writing jobs, so they are not here. Customer-service chatbots, which the SBA guide, Salesforce and MindStudio all list, are not here either: a chatbot needs a website widget, a written knowledge base and someone reading its misses, and a one-person shop gets the same result by running the customer-email prompt on each question in its own voice. Add one when the same questions arrive faster than you can paste them.

This page is published by Whizi, which sells the chat plan side of that table: GPT, Claude, Gemini and 280+ other models on one login, from $15.99 a month, and a two-column compare on its Pro and Powerhouse plans for the quote, bookkeeping and contract rows. Where it loses is the right-hand column. Whizi has no bookkeeping integration, no point of sale and no CRM, so QuickBooks, Square and HubSpot stay on the bill whatever you do about the writing.

How do you make the AI sound like your business instead of a template?

Give it a one-page business brief once, and paste it ahead of every prompt or save it where the tool re-reads it. The brief is 150 to 250 words: what you sell, to whom, your prices or a link to the list, your tone in three adjectives and two banned phrases, your hours, your policies on deposits, refunds and rescheduling, and one real email you wrote that you liked. Every prompt in the first table gets shorter once the brief exists, because "keep my tone" now means something.

The brief prompt I use: "Here is a description of my business and a sample of my writing. Keep both in mind for everything I ask in this chat. If a question needs a fact that is not here, ask me instead of guessing. Business: [paste]. Sample: [paste]." Then send the job.

Where the brief lives depends on the tool. ChatGPT and Claude both offer a project or custom instruction slot for it. On Whizi it goes in a Project: per-project instructions up to 32,000 characters plus up to 10 pinned files (PDF, Word, Excel or CSV, 10 MB each), so the price list and the sample email ride along on every message in that project without pasting. That is the single product mention this page needs; the brief works anywhere.

The two-model step is for the rows marked yes in the first table. Send the quote, the bookkeeping question or the contract read to two model families, GPT and Claude say, with the same brief, and read only the points where they differ: a subtotal, a clause one calls standard and the other flags, a rule one says applies in your state. The disagreement is the list of things to check or to bring to your accountant or lawyer. On a social post or a customer email, two answers teach you nothing you would not learn by editing one.

What should a small business owner never paste into an AI chat?

Customer card numbers, employee Social Security or Social Insurance numbers, bank logins, and any customer's medical or financial detail. Replace them with placeholders ([customer], [account ending 4412]) before you paste; the model does not need the real value to draft the email. The SBA guide gives the same instruction in its own words: avoid feeding sensitive or proprietary information to AI systems. What never to paste into an AI chat is the full list with the reasons. If you run an insurance agency, AI for insurance agents quotes the NAIC data security model law that defines the client data to keep out of a chat.

The contract and bookkeeping rows carry a second limit. A model reading your lease or your supplier agreement can list and rate the clauses, and that is what the contract prompt asks for, but it does not know your state's or province's law, and it will state a rule confidently when it is wrong. Take the ask-a-lawyer clauses to a lawyer, and the bookkeeping disagreements to your accountant, as questions rather than as answers. That keeps the model doing what it is good at, reading and drafting, and keeps the decisions with the person who is liable for them.

Disclosure is the last question owners ask, and the SBA's guide suggests considering a public statement about how you use AI. My rule: a review reply or a customer email goes out under your name, edited by you, and needs no label; a job ad or a policy page a customer relies on gets a human read before it publishes, and if a customer asks, you say yes, and that you checked it.
