The Best Way to Set Up an AI Assistant for Small Business

The best way to set up an AI assistant for a small business is to pick ONE paid assistant, spend an hour teaching it about your business, and point it at three jobs that already eat your week: winning customers, getting found, and admin. You do not need thirty tools. You need one, set up well, doing real work.

Here is the exact setup, in order, with what 'done' looks like at each step and roughly how long it takes. Block out a couple of hours across the week and you will have a working AI assistant for your small business by Friday.

Step 1: Pick one assistant and pay for it (10 minutes)

The two safe choices are ChatGPT and Claude. Both cost the same at the entry paid tier. ChatGPT Plus is a subscription plan that provides enhanced access to the ChatGPT web app for $20/month. Claude Pro costs $20 per month billed monthly, or $17 per month on an annual plan. In the UK that lands around 17 to 20 pounds a month depending on the plan and exchange rate.

Which one? If you mostly want to write posts, emails and replies, either is fine. If you want the assistant to read your documents and answer as if it already knows your business, both handle that too. My rule: open the free version of each, ask it the same real question about your trade, and pay for whichever answer you would have sent. Do not agonise. You can switch later.

One thing worth knowing before you rely on it: these tools quietly route your question to different underlying models. The Auto selector may route a query to a flagship or a lighter model based on logic OpenAI has not fully documented. On a hard prompt, you get the flagship. On a routine one, you may not. In practice, for a small business that just means: check the important stuff before you send it.

Done looks like: you are logged in to one paid assistant on your laptop and phone.

Step 2: Write a one-page brand brief (20 minutes)

This is the step everyone skips, and it is the difference between generic waffle and copy that sounds like you. Open a blank note and write down: what you do, who you help, your town or service area, your three most-booked jobs, your rough prices or pricing rule, your tone (plain and friendly, no jargon), and three things you never say.

Now paste that into your assistant and tell it to remember it. In ChatGPT this goes in Settings under custom instructions or a saved memory. ChatGPT custom instructions are persistent user preferences that guide how ChatGPT responds across conversations. In business use, they help the model understand your company context, tone, and output format so recurring tasks need less repeated prompting.

Done looks like: you can start a fresh chat, ask for a Facebook post, and it comes back sounding like your business without you re-explaining who you are.

Step 3: Build a reusable 'business brain' the assistant can read (30 minutes)

Both ChatGPT and Claude let you save a custom assistant loaded with your own files, so it answers from your actual policies instead of guessing. A custom GPT is a version of ChatGPT that you configure once with your own instructions, documents and tool connections, so it answers as someone who already knows your business. Creating one takes about twenty minutes, requires no code, and needs a paid ChatGPT plan.

Gather your real documents: price list, service list, FAQs, warranty or returns policy, opening hours. A few tips that genuinely matter for how well it reads them. Markdown or plain text beats PDF. Use descriptive filenames, refund_policy_2026 not doc3. Fewer, better files: ten well-organised documents beat forty overlapping ones.

In ChatGPT, go to Explore GPTs, click Create, and fill in the Configure tab. Fill the Configure tab with Name, Description, Instructions, attach Knowledge files, tick Capabilities, then choose visibility: Only me, Anyone with the link, or GPT Store. Keep it as 'Only me' for now.

Done looks like: you ask 'what's our call-out charge for a Saturday?' and it answers correctly from your own file.

Step 4: Point it at winning customers (30 minutes)

This is where the money is. Use your assistant plus your brand brief to batch a month of social posts and emails in one sitting. A prompt that works: 'Using my brand brief, write me 12 short social posts for the next 4 weeks. Mix of a job we did, a common question, a seasonal tip, and one offer. Plain English, no hashphrases, under 60 words each.' Edit, schedule, done.

Worked example, a plumber. On Monday you finish a boiler swap. You ask your assistant: draft a text asking that customer for a Google review, draft a friendly reply for when it lands, and write two posts about 'signs your boiler is on its way out.' Ten minutes, and you have filled your review pipeline and your feed at once. Reviews are worth the effort here. If there is one factor that influences both rankings and customer decisions simultaneously, it is Google reviews. In 2026, reviews are not just social proof, they are algorithmic signals Google uses to determine your prominence, trustworthiness and relevance.

The review system that works: ask at the peak moment. Identify the trigger moment, usually right after completing a job successfully, create a direct Google review link, and automate the ask by sending an SMS or email with the review link within 2 hours of service completion. Your assistant drafts every message and every reply.

Done looks like: a month of posts scheduled and a saved review-request text you send after every job.

Step 5: Get found by AI and Google (40 minutes)

More people now ask an assistant 'best plumber near me' instead of scrolling links. The foundation for being found is still your Google Business Profile, and it is free. Your Google Business Profile is the single highest-leverage free marketing asset a small business owns in 2026. It is what Google shows in the map pack, in Maps, in mobile searches with local intent, and increasingly in AI-generated answers.

Do these in order. First, the biggest lever: switching a category to the narrowest accurate one can change Maps visibility more than any other on-profile edit. Choose the narrowest accurate category. Then complete every field, because complete, optimized profiles receive 70% more location visits than incomplete ones. Then post weekly and keep an eye on questions. Unlike your business information, anyone can post a question or answer in your Q&A section, including competitors. Set a Google Alert for your business name and check your Q&A section weekly.

Here is the part that ties back to your assistant. Google now builds its own answers from everything you publish. Google's AI actively combs your entire digital footprint including your business description, services catalog, website content, and past reviews to formulate a context-aware answer. Managing your Q&A in 2026 is about feeding Google's AI engine the right data. So the more clear, plain answers to real customer questions you have on your profile and site, the more you get quoted. Use your assistant to draft answers to the five questions customers actually ask: what it costs, what goes wrong, how you compare, who you are best for, and what people say.

Done looks like: profile 100% complete, narrowest category picked, and your top five customer questions answered in plain text.

Step 6: Automate one admin job that eats hours (45 minutes)

Do not automate everything at once. Pick the ONE task that annoys you most, usually chasing quotes or invoices, and wire up a single automation. The tool for a non-technical owner is Zapier or Make.com. Both have free tiers. Make offers a free plan with 1,000 credits per month, enough to try the product and run a few light automations.

On value, Make is the cheaper starting point. Make.com Core at $10.59/month is roughly 47% cheaper than Zapier Starter at $19.99/month, while delivering 10,000 operations versus Zapier's 2,000 tasks. But if you want the simplest possible builder, start with Zapier. Non-technical teams default to Zapier. Teams needing complex logic and moderate technical skill get the most from Make.

Worked example, a salon: a new booking form entry triggers a confirmation text, adds the client to your list, and 24 hours before the slot sends a reminder. One automation, no more no-shows eating your day.

Done looks like: one automation running by itself that you used to do by hand.

What to do next

1. Today: pay for one assistant (ChatGPT Plus or Claude Pro, about 17 to 20 pounds a month) and write your one-page brand brief into its settings. 2. This week: complete your Google Business Profile, pick the narrowest accurate category, and use your assistant to draft answers to your five most common customer questions. 3. By Friday: batch a month of posts, save a review-request text to send after every job, and set up one automation for the admin task you hate most.

That is a full AI assistant setup for a small business, done in under three hours across a week. If you would rather work through it alongside other owners doing exactly the same thing, that is what the AIBL Club is for. Start with step one though, because a paid assistant with your brand brief in it is already earning its 20 quid before you finish reading this.
