Questions
Before you dive in
Are these business tools free?
Yes. All 26 tools are completely free with no limits, no premium tier, and no account required.
Is my invoicing and pricing data uploaded anywhere?
No. Every tool runs entirely in your browser. Client details, prices, margins and stock figures never leave your device, which is the main reason to use these rather than a cloud service for commercially sensitive data.
Do these replace accounting software?
No. They produce documents and calculations, but they do not keep books, reconcile a bank feed or file anything. Use them alongside your bookkeeping rather than instead of it.
Can I reuse a document for the same client?
Yes. Every document generator can export its data as a small .json file that you load back later, so repeat work only needs the number and dates changing.
