Claude Code for Non-Developers Internal tool from a spreadsheet

A quote tool your team opens from a private link, proven to give your spreadsheet's answers on past quotes before its mistakes are fixed.

• The guide: 24 pages, worked through a quote calculator for a kitchen fitter
• Copy-paste prompt library: 12 prompts (PDF and plain text)
• Checklist PDF: the weekend plan, worksheets for your spreadsheet map, known answers and brief, a check to run before every publish, and the whole guide on one page

You'll need Any paid Claude plan (Pro or higher) and a Mac or Windows computer where you can install apps. For the private link: a free Cloudflare account; its Zero Trust Free plan asks for a payment card, but nothing is charged on the Free plan.

Questions

Do I need to be a developer?

No. Claude Code writes and runs the code. You describe what the tool must do, answer its questions about your business and check its results against answers you know are right.

What do I need?

Any paid Claude plan (Pro or higher) and a Mac or Windows computer where you can install apps. For the private link you also need a free Cloudflare account.

Is it safe to let Claude Code read my spreadsheet?

Work on a copy with customer names, addresses and notes removed, in a folder that holds nothing else. The setup chapter walks through the privacy settings to check first.

Which spreadsheets is it for?

Spreadsheets that calculate from your own rules but store nothing, such as quotes, estimates, planning and commission sums. A tool that will hold customer or patient data needs a stricter build than this edition covers.

How do I get the guide after paying?

The download buttons appear on the next page as soon as payment completes. We also email you a link to your library, so you can download again later from any device.

Do I need an account or a password?

No. Your library link arrives by email. If you lose it, enter your email on the library page and we send a fresh one.

What's the licence?

One person. Each PDF is stamped with the buyer's email address and order number. Buying for a team? Email us and we'll sort out a team licence.

Can I get a refund?

Because you get the download straight away, the 14-day right of withdrawal for online purchases ends once the files are available to you. You agree to that at checkout. If a file is faulty or doesn't match its description, email us and we'll fix it or refund you. The full rules are in our terms of sale.

Is VAT included?

Yes, prices include VAT for consumers. Businesses elsewhere in the EU that enter a valid VAT number at checkout pay no Dutch VAT and get an invoice with reverse charge. Every order gets a receipt and an invoice PDF.

Are the examples real businesses?

No. Each guide works through a clearly labelled fictional business, built for real while we wrote it, so every step has been tested. Real companies appear only as cited public case studies.

What if a tool changes after I buy?

Each guide names the tools but teaches the method, and carries a last-tested date. We re-test every quarter, and updated versions appear in your library for free.
