Explain your business to Claude once

Start with whatever you get asked about most. For most small businesses that is what you sell, how you sound and how one recurring task is done. One page each is plenty.

1. what-we-sellPrices, packages and the ten questions customers ask most. This one file takes the most "quick questions" off your plate.
2. how-we-writeOne master voice file. Channel notes for email or LinkedIn can add detail, but they never override it.
3. how-we-workOne recurring task, step by step: when it happens, who does it, what done looks like.

# Prices
Last checked: 4 November 2026. Prices exclude VAT.
Office clean, up to 100 m²: 120 € per visit
Deep clean: from 380 €, quote after a site visit
We never discount the deep clean. Regular clients get 10% after six months.

You don't have to write the files from scratch. Paste one of these prompts into Claude and let it interview you.

Interview me to write a file called what-we-sell.md for my business, [BUSINESS NAME]. Ask one question at a time about what we offer, our prices, what is included and not included, and the ten questions customers ask us most. When you have enough, write the file in short sections with plain headings. Mark anything I was unsure about with [CHECK].

I will paste three messages I sent to customers that I was happy with. Read them and write a file called how-we-write.md: how we sound in three words, words we use and avoid, sentence length, and how we greet and sign off. Keep it under one page. Then list anything that contradicts itself across the examples.

Interview me about one task we repeat: [TASK]. Ask what triggers it, who does it, the steps, what a good result looks like and the mistakes people make. Then write how-we-work.md as numbered steps a new hire could follow on day one.

Once the three files work, the folder grows into seven. CLAUDE.md sits at the top as the map: it tells Claude what to read first and what to do when files disagree.

The template has every folder and file ready, with placeholders to fill in.

Whatever goes in, every AI chat on your team can repeat. So keep these out:

• Passwords and API keys (an API key is a password for software)
• Bank and card details
• Client personal data you do not need
• Salaries and HR notes

Finances and HR go in a separate private project that only the owner can open.

One person edits. Everyone else reads. On the Claude Team plan, give the owner "can edit" and everyone else "can view".

When something is wrong, people tell the owner instead of saving their own fixed copy. That is exactly how I ended up with four voice files.

1. Pick three questionsOne about a price, one about a reply to a customer, one about a recurring task.
2. Two people ask themEach in their own chat, inside the shared project.
3. Compare the answersSame answer? It works. Different answers? A file is unclear or missing, and now you know where to look.

Keep the files in a folder the business owns, not in someone's personal account. Then put them into one shared Claude project, set up by the business owner, so knowledge stays when people leave.

Claude Team is for 2 to 150 people. A standard seat is $25 per person per month billed monthly, or $20 billed annually. Those are Anthropic's US prices, checked on 4 November 2026; prices vary slightly in Europe and taxes come on top.

On Team and Enterprise, Anthropic does not train its models on your content by default. On Pro or Max you are on the personal plan terms, which have their own privacy setting.

• It needs an owner. Without one, it goes stale and people quietly stop trusting it.
• More is not better. Long, contradictory files make answers worse. Short and current beats complete.
• It will not settle a process nobody agrees on. It just hands you the disagreement faster.
• Claude can still get things wrong. Someone checks before anything goes to a customer.
