# Write an AI business plan you can check and keep updating

> Use your AI app to turn customer evidence, costs and open questions into a business plan. Ask it to label assumptions and keep the figures in a separate table. Save both in 1folder, where another connected app can review and update the same files. The AI app drafts the plan; 1folder keeps it.

*Picture: Repair studio plan, a page saved by ChatGPT: Offer: small clothing repairs, collected locally; Evidence: eight customer interviews supplied; Test: two Saturday collection sessions; Unknown: how many enquiries become paid jobs; Next decision: rent space only after testing demand. Studio assumptions, a table saved by Claude (Assumption, Value, Basis): Jobs per month, 80, Untested; Price per job, £20, Proposed; Variable cost per job, £5, Estimate; Fixed monthly costs, £900, Draft budget; Remainder at 80 jobs, £300, Before tax and owner pay.* An example clothing repair studio: the plan beside the numbers it rests on, with the untested ones labelled as untested.

## What you end up with

- **Repair studio plan** (a page, saved by ChatGPT): An example plan for a clothing repair studio: the offer, the evidence so far, a small test and the decision still open.
- **Studio assumptions** (a table, saved by Claude): £1,600 in sales, less £400 of materials and £900 of fixed costs, leaves £300. Each input says how sure it is.

## An AI business plan generator needs your inputs first

Start with the customer, the problem, the offer and the evidence you have collected. Add actual quotes for equipment, proposed prices, available time and the costs you expect. Ask for questions before prose. A convincing paragraph about a large market is of little use if nobody has checked who would buy from this particular business.

ChatGPT Projects can group the chats, files and instructions for this work, and you can draft the whole plan there. A shared folder helps when you want a second AI app to challenge the numbers, or an adviser to read the current plan.

An AI generated business plan should make the guesses easier to see, not harder. Here, eight interviews are evidence, 80 jobs a month is a guess, and two Saturday collections are the test. Ask the app to keep those labels as the writing gets more polished.

## What to ask the AI app to put in the plan

- The problem and who has it, in a sentence each.
- What you sell, at what price, and why someone picks you.
- The evidence so far: interviews, pre-orders, a pilot, with dates.
- Costs: one-off and monthly, each with its quote or estimate.
- The numbers at a low, middle and high month, not one forecast.
- The risks, and the next small test that would answer the biggest one.

## Keep the financial model small enough to inspect

In the example, 80 jobs at £20 bring in £1,600. Materials at £5 a job cost £400. Take off £900 of fixed costs and £300 is left, before tax and before paying the owner. Ask the app what’s missing: hours worked, refunds, card fees, costs still being quoted.

Give each number a unit, a period and a basis. When a new quote changes a cost, update that row and ask the app to bring the plan’s text into line. A small table you understand beats a big spreadsheet you don’t.

## Keep the working plan and the copy you send

1. **Collect the evidence and connect an app.** Put your interview notes and quotes in a Repair studio folder. Add https://1folderapp.com/mcp as a custom connector in [Claude](https://1folderapp.com/integrations/claude-connectors.md), or in [ChatGPT](https://1folderapp.com/integrations/chatgpt-connectors.md) on Business, Enterprise or Edu, sign in and allow that folder.

   *Picture: 1folder’s Allow page: “Claude wants to use your 1folder”, with Only the folders I pick in Repair studio and View and edit chosen, then Allow.*
2. **Save the plan and its assumptions separately.** Ask for a page explaining the business and a table containing the figures. Check that the written claims agree with the source notes.

   *Picture: In ChatGPT, you type: “Save the repair studio plan with evidence, assumptions and open questions clearly marked.” ChatGPT saves Repair studio plan (a page saved by ChatGPT) to 1folder.*
3. **Revise from actual results.** Provide pilot results and ask the next connected app to read the existing files before changing them. Compare versions to see which assumptions moved.

4. **Send a reviewed edition.** Keep one plan current. For a bank or an adviser, save a dated copy and download it as a [PDF file](https://1folderapp.com/how-to/chatgpt-to-pdf.md) or a [Word file](https://1folderapp.com/how-to/chatgpt-to-word.md).

## Use AI for a business plan built from evidence

- In ChatGPT: “Use these eight customer interviews and my cost notes to draft a repair studio business plan. Separate evidence, assumptions and unanswered questions. Ask for missing information before adding financial claims. Save the reviewed draft to 1folder.”
- In Claude: “Read the repair studio plan in 1folder. Save a monthly assumptions table: jobs, price, variable costs and fixed costs, with units and sources. Treat 80 jobs at £20 as an untested scenario, not a forecast.”
- In Claude: “Check the repair studio arithmetic at 40, 80 and 120 jobs per month. Include £5 variable cost per job and £900 fixed costs. List omitted expenses and wait before changing the plan.”
- In ChatGPT: “Read the latest plan and these pilot results. Update the same plan and assumptions table in 1folder. Explain which assumptions changed. Create a separate reviewed copy for the adviser after I approve it.”

## Questions

### Does 1folder generate a business plan or provide a template?

No. There is no AI inside 1folder and it has no templates. Your AI app writes from what you give it; 1folder keeps the plan and every later version.

### Can I use business plan AI without customer research?

You can ask for the structure and the questions to go and answer. But a draft can’t prove anyone will buy, so mark those parts as gaps until you’ve talked to customers.

### Will the plan be good enough for a bank?

Ask the bank what it wants to see and give that list to your AI app, so the plan follows it. Have an adviser read the finished plan before you send it.

### Can another app challenge the assumptions?

Yes, once it’s connected to the folder. Ask it to read the plan, the notes and the numbers together and list what it disagrees with, then save only the changes you pick.

### Can I share only the finished plan?

Yes. Turn on the public link for that one file, or download it as PDF. Take out supplier quotes and personal details first; the source files stay private.
