How to start a business with AI: a 30-day plan from idea to first customer

Starting a business used to mean doing every job yourself, or paying someone for each one. AI changes the first part. It can draft your website, question your idea, suggest names, write your first posts and turn rough notes into a plan, all in plain English. If you can write an email, you have the skill you need.

What it can't do is know your customers, set your prices or take responsibility for your tax and legal duties. It also states wrong things with confidence, especially about rules and figures. Treat it as a capable first-drafter and thinking partner. You stay the owner.

• One AI assistant. Such as Claude, Copilot, Gemini or ChatGPT. You don't need a paid plan to follow this guide. Pick one and stay with it. If you're not sure which, see which AI tool to start with.
• One document for your business. Call it your business brief. You'll add to it every week, and paste it at the start of new AI chats so you don't have to explain yourself each time.
• About an hour a day. Some days need less. Talking to customers in week one needs more.
• A privacy habit. Keep other people's personal details out of free chatbots, and switch off model training in your account settings.

The aim this week is to find out whether people want what you plan to sell, before you spend money on it. AI is very good at helping you think. It can't tell you whether people will buy. Only potential customers can do that.

1. Days 1 and 2: describe the idea. Write a few sentences on what you'll sell, who it's for and why they'd choose you. Ask AI to question it hard.
2. Day 3: map the competition. Ask AI for the kinds of businesses your customers choose today, then search for them yourself. AI's lists can include businesses that have closed or never existed.
3. Days 4 to 6: talk to five to ten potential customers. Ask AI to write interview questions about the problem, not your solution, so people don't just say what you want to hear.
4. Day 7: make sense of it. Paste your notes from the conversations, with names removed, and ask what came up again and again, and what surprised you.

Try: "I want to start a mobile bike repair service for commuters in Manchester. Act as a sceptical investor. Ask me ten hard questions about this idea, one at a time, and after my answers tell me the three biggest risks and how I could test each one cheaply this week."

1. Days 8 and 9: write the offer. What exactly does the customer get, how, by when, and what isn't included? Ask AI for three ways to package it, such as a single service, a bundle and a monthly option. Choose one to start.
2. Day 10: work out your numbers. Ask AI to list the costs you might have forgotten and the questions to answer before you set a price. Set the price yourself, based on your costs and what customers told you in week one.
3. Day 11: choose a name. Ask for 30 ideas in different styles, shortlist five and say them out loud to people. Then check the rules (below) and whether the website address and social handles are free.
4. Days 12 to 14: write a one-page plan. Ask AI to turn your brief into a simple business plan: the customer, the offer, the price, how you'll find customers and your costs for the first months. Ask it what you've missed.

GOV.UK says a sole trader's business name must not include "limited", "Ltd", "LLP" or "plc", must not be offensive and must not be too similar to an existing trade mark. A limited company name has its own rules. AI can't check trade marks for you, so search them yourself through the links on GOV.UK.

If you want a fuller plan, GOV.UK's business plan page points to free business plan templates from The King's Trust and Start Up Loans, and a free cash flow forecast template from Start Up Loans. Ask AI to help you fill one in, section by section.

1. Days 15 to 17: a simple website. You need one clear page more than a big site: what you offer, who it's for, the price or how to get a quote, and how to get in touch. Most website builders have templates. Ask AI to write the words, then ask it to read the page as a first-time visitor and say what's unclear.
2. Day 18: your profiles. Choose one or two places where your customers already spend time. Ask AI for a short bio for each, in your own tone.
3. Days 19 and 20: your first posts. Ask for ten post ideas based on the questions customers asked you in week one. Write or edit five. Use your own photos.
4. Day 21: tell the people you know. Ask AI to help you write a short, personal message to friends, former colleagues and contacts saying what you've started and who it would help. Send it yourself.

Try: "Here's my business brief. Write the text for a one-page website: a headline that says what I do and for whom, three short sections answering the questions customers asked me most, and a clear call to action to book a free 15-minute call. Plain British English, no hype, under 300 words."

AI can explain the options and make templates, but the facts below come from GOV.UK. Check them there before you act, because thresholds and fees change.

• Choose a structure. Most people start as a sole trader or a limited company. GOV.UK sets out the differences, including that sole traders are personally responsible for business debts.
• Sole trader. You can start trading straight away, but you must register for Self Assessment if you earn more than £1,000 in a tax year. The deadline to tell HMRC is 5 October after the end of the tax year. You must keep records from the day you start trading.
• Limited company. You must register with Companies House before you trade. Registering online costs £100 and is usually done within 24 hours.
• VAT. You must register if your taxable turnover for the last 12 months goes over £90,000.
• Making Tax Digital. Sole traders with qualifying income over £30,000 in the 2025 to 2026 tax year will need to use it from April 2027, and over £20,000 from April 2028. Check the current thresholds on GOV.UK.
• Data protection. If you use personal information, such as customer contact details, you may need to pay the ICO's data protection fee, unless you're exempt.

Then let AI help with the paperwork you'll use every week: a reply to enquiries, a quote template, an invoice layout and a short set of terms. Anything legal, such as your terms and conditions or a privacy notice, is a first draft until you've checked it against official guidance or with a professional.

Finally, ask for the sale. Go back to the people from week one who said they had the problem and offer them your service. Ask AI to help you prepare for the conversation, including the objections you might hear, and practise by asking it to play the customer.

• Tax and legal rules. AI may give old thresholds, rules from another country or a confident guess. Use GOV.UK and HMRC as the source, and AI only to explain them in plainer words.
• Market figures. If AI quotes a market size or statistic, ask for the source and open it yourself. If it can't give one, don't use the number.
• Agreeing with you. AI tends to be encouraging. Ask it to argue against your idea, or to play a sceptical customer, to get a more honest view.
• Sounding like everyone else. Your story, your photos and your way of talking are what make people choose you. Edit every draft until it sounds like you.

• Government business support. GOV.UK lists free business support for each part of the UK: the Business Support Service in England, Find Business Support Scotland, the Business Wales Helpline and Invest Northern Ireland.
• Start Up Loans. A government-backed loan of £500 to £25,000 for people starting or growing a business that has been trading for less than five years. GOV.UK says successful applicants get up to 12 months of free mentoring. It's a personal loan, so read the terms and the interest rate on the Start Up Loans page first.
• Business plan templates. Free templates linked from GOV.UK's business plan page.

Once customers start coming in, the next step is making AI part of your daily routine. How to use AI in your small business covers ten everyday jobs, and the Studio shows how an enquiry can become a draft reply, a booking and an invoice. If you'd like to go through this plan with support, that's what the AI Business Launchpad is for.
