Which business tool do I need?
- Adding or removing UK VAT: the VAT calculator works at 20%, 5%, 0% or a rate you choose, and shows the formula.
- Setting a price: the markup and margin calculator works from cost and markup, cost and price, or a target margin, and explains why a 50% markup is only a 33.3% margin.
- Billing a client: the invoice generator makes a clean invoice you can print or save as a PDF, with no account and no upload.
Built for checking, not for your books
These tools are quick checks for small businesses and freelancers. For VAT returns, tax and record keeping, follow the official guidance quoted on each page or your accountant. The invoice generator lists what GOV.UK says an invoice must include, but it does not replace accounting software.
Common questions
Are my invoices or prices stored anywhere?
No. Everything is worked out in your browser. The invoice generator can remember your own business details on your device if you tick that box, and never stores client details or line items.
Can I use other currencies?
The invoice generator lets you pick dollars, pounds, euros or your own symbol. The VAT calculator is for UK VAT in pounds.
