How to Use AI for Your Small Business: Claude, ChatGPT and Gemini Setup
· 9 min read
The simplest way to use AI for your small business is to stop starting from a blank chat. Write one page of facts about your business, turn each job you repeat every week (quotes, customer replies, review replies) into a saved "helper" with its own instructions, and check every draft before it goes out. Claude and ChatGPT can hold saved instructions on their free plans, Gemini's new skills are open to personal Google accounts, and the setup takes about an hour.
Below: the setup step by step for a small service business, a filled-in example, each app's menus as of late October 2026, and the privacy settings to check. If you use Gemini Gems, note that Google replaces them with "skills" in November 2026.
Why a blank chat gives you generic answers
If you open a chat and type "write a quote for a 3-bedroom house clean," the AI doesn't know your prices, your towns, your cancellation policy or how you talk to customers. So it guesses, and a guess can turn into a price or a promise you never made.
A saved helper has three parts:
A business profile: your services, prices, service area, policies and tone, written once.
Instructions for one job: what the helper does, what it must ask before drafting, and what it must never do.
A human check: you read, fix and send. The SBA's AI guidance says to "have another person review all AI products" and to make sure a person checks the messages AI generates (SBA: AI for small business).
You'd be early, not late. The Census Bureau's Business Trends and Outlook Survey found 19.8% of US businesses were using AI as of May 3, 2026, and fewer than 20% of firms with four or fewer employees (Census Bureau, May 2026).
Step 1: Pick three jobs to hand off first
Start with writing jobs you do every week, where a draft saves time and you can easily spot a mistake. For most service businesses that's:
Quotes and estimates from your own price list.
Customer replies: booking questions, reschedules, complaints.
Review replies for Google and other sites.
Later: Google Business Profile posts, payment reminders, job ads and checklists. Anything that needs a lawyer or accountant stays with them; AI can draft your questions.
Step 2: Write a one-page business profile
This is the most important file. Every helper reads it, so your facts live in one place and you only update prices once. Keep it to a page and include:
Basics: business name, owner name, phone, hours, towns or ZIP codes you serve.
Services and prices: each service with its price or price rule, add-ons, minimum charge.
Policies: deposits, cancellation and reschedule rules, payment methods, what you don't do.
Tone: three or four words ("friendly, short, no exclamation marks") and how you sign off.
Never say: promises you can't keep ("guaranteed spotless"), discounts you don't offer.
What stays out: customer names and addresses, card or bank numbers, passwords, employee details, and anything you'd be upset to see leaked. More on that below.
Worked example: a filled-in profile
Here's a short profile for a fictional solo cleaner, Brightside Home Cleaning (made up for this guide; the prices are examples, not a recommendation; to set yours, see our house cleaning pricing guide):
BUSINESS: Brightside Home Cleaning. Owner: Dana. Mon-Fri 8-5.
AREA: Maple Falls and Cedar Grove only.
STANDARD CLEAN: 1-2 bed $130, 3 bed $160, 4 bed $195.
FIRST VISIT: deep clean = 1.5 x standard price.
ADD-ONS: inside oven $35, inside fridge $30.
MINIMUM: $130. No discounts unless Dana approves.
POLICIES: 48-hour reschedule notice or $40 fee. Card or Zelle.
WE DON'T: move furniture over 50 lb, clean mold, wash outside windows.
TONE: warm, plain, short. Sign off "- Dana, Brightside".Step 3: Write the instructions for one helper
Each helper gets its own short instructions. A pattern that works: role, inputs, rules, output, check list. Here's a Quote Writer for the profile above:
You write quotes for Brightside Home Cleaning using ONLY the
business profile. Before drafting, ask for anything missing:
bedrooms, first visit or repeat, add-ons, town.
Rules: use only prices in the profile and show the math line by
line. Never invent discounts, prices, or services. If the town is
outside the service area, say so politely. Never promise results.
Output: a short message to the customer, then the price math.
End with "Check before sending:" and the 2-4 things to confirm."Ask for anything missing" stops the guessing; "show the math" lets you check the price in seconds.
Step 4: Save the helper in your app
Menus change often, so each step links the app's own help page (checked October 26, 2026).
Claude: skills
Claude skills are on the Free, Pro, Max, Team and Enterprise plans and need code execution turned on (Claude help: use skills).
On a personal plan, go to Settings > Capabilities and turn on code execution and file creation.
Put your instructions in a file named SKILL.md (it starts with a short name and description header; Claude's help page shows the format) inside a folder with the skill's name. Add your profile to the same folder and zip it.
Go to Customize > Skills, click +, then Create skill > Upload a skill, and upload the ZIP.
If that's more than you want to do today, pasting the profile and instructions at the start of a chat works too; it just isn't saved.
ChatGPT: a project
For Free and Plus accounts, a project is the way to save instructions. ChatGPT's own skills feature is currently listed for Business, Enterprise, Healthcare and Edu users (OpenAI: skills in ChatGPT).
Click New project in the sidebar and name it ("Brightside quotes").
Open the project's ••• menu > Project settings and paste the instructions. Project instructions override your general custom instructions.
Upload your profile as a file. A project holds 5 files on Free, 25 on Go and Plus, and 40 on Pro, Business, Edu and Enterprise (OpenAI: projects).
Tip: choose project-only memory so the project doesn't pull in your personal chats.
Gemini: skills (Gems are going away)
Google announced on September 30, 2026 that skills replace Gems (Google blog). For personal accounts, Gems become read-only on November 17, 2026 and are removed on December 17, 2026; Google says it migrates Gems to skills automatically, but download any files you need before December 17 (Gemini help: Gems to skills). Workspace business accounts follow in March 2027.
To set up a new helper now, use a skill:
Go to gemini.google.com > Customize > Skills.
Click Create > Create manually, then paste the name, a one-line description and your instructions.
Use it in any chat by typing "/" and the skill's name.
Skills are currently for people 18 and over on personal Google accounts, and you can have up to 100 active at once. Google's help page doesn't name a paid plan as a requirement, and TechRepublic reports that Google confirmed skills don't need a paid Google AI subscription.
Step 5: Test it before you trust it
Run one sample request and check the answer against your profile. Using the Brightside example:
Request: "New customer in Cedar Grove, 3-bedroom house, first visit, wants inside oven and fridge."
What a good answer contains:
First-visit deep clean: 1.5 × $160 = $240
Inside oven: $35
Inside fridge: $30
Total: $240 + $35 + $30 = $305
A note that repeat cleans would be the standard $160, plus any add-ons they want that visit
The 48-hour reschedule policy, signed "- Dana, Brightside"
A check list such as "Confirm bedrooms; confirm the add-ons are wanted on every visit or only the first"
Red flags: a "10% new customer discount" (not in the profile), an oven price that isn't $35, or a promise like "spotless guaranteed." If you see one, tighten the instructions and test again. Keep this request and answer as your test for every future change.
Then build helpers two and three the same way. For review replies, add one hard rule: reply to reviews, never write them.
Privacy settings and what never to paste
AI apps keep your chats for a time, and some use them to improve their models. Check these settings before you add business information:
Claude: Settings > Privacy > "Help improve our AI models" controls whether your chats are used for training (Claude privacy help).
ChatGPT: Settings > Data Controls > "Improve the model for everyone." Temporary Chats aren't used for training and are deleted within 30 days (OpenAI data controls FAQ).
Gemini: the Keep Activity setting. Google says human reviewers see some chats and asks you not to enter confidential information you wouldn't want a reviewer to see; with Keep Activity off, chats are still kept for 72 hours (Gemini Apps Privacy Hub).
Whatever the settings, never paste: card or bank numbers, Social Security numbers, passwords or door codes, customers' full names with addresses, employee records, or anything covered by a confidentiality agreement. Write "the customer" or a first name instead. The SBA gives the same advice: try not to feed AI tools sensitive data or proprietary information.
Rules AI can't bend for you
Reviews: the FTC's rule on fake reviews, in effect since October 21, 2024, bans fake reviews, including reviews by "someone who does not exist, such as AI-generated fake reviews," and lets courts impose civil penalties for knowing violations (FTC rule announcement; FTC Q&A). Use AI to reply to real reviews, never to write them. For getting real reviews, see how to get cleaning clients without paying for leads.
Facts and promises: you're responsible for what you send. Check any price, law or guarantee.
Legal, tax and hiring questions: rules vary by state and city. Use AI to make a list of questions, then check official sources or a professional. This guide isn't legal or tax advice.
Common mistakes
Skipping the profile and pasting prices into every chat, so they drift out of date.
One giant helper for everything. One job per helper gives steadier answers.
Sending without reading. Every draft gets a human check, every time.
Pasting customer data to "give it context." First names and job details are enough.
Never retesting. Apps change models and menus; rerun your test monthly.
If you'd rather not write the instructions yourself, our AI Skills Pack for Small Business Owners has 12 ready-made helpers (quotes, replies, reviews, payment reminders and more) built around one business profile, as Claude skill ZIPs plus plain text for ChatGPT and Gemini, with a test sheet for each.
FAQ
Do I need a paid AI plan?
No. Claude skills are on the free plan, ChatGPT Free projects hold 5 files (your profile plus room for reference files), and Gemini skills are open to personal Google accounts without a stated paid-plan requirement. Paid plans add higher limits and more files.
Which AI is best for a small business?
The one you'll use. All three follow saved instructions well enough for drafts. Start with the app tied to tools you already use, then run your test in another app if you're curious.
Do I have to tell customers I use AI?
The SBA notes that no federal or state law currently requires businesses to disclose AI use, but calls disclosure an emerging best practice. Laws change and can differ by state, so check before you rely on that, especially for chatbots that talk to customers directly.
What happens to my Gemini Gems?
On personal accounts, Google converts them to skills: they turn read-only on November 17, 2026 and disappear on December 17, 2026. Open each Gem, check it works as a skill, and download any files you uploaded before December 17.
