Business Tools
13 toolsFinance calculators for tax, loans, investments and pricing decisions.
Documents and calculations a small business needs on an ordinary day: an invoice to send, a receipt to issue, a quotation to win the work, and the tax and margin arithmetic behind all three.
The document tools share one engine, so a quotation, a purchase order, a challan, an invoice and a receipt all look like they came from the same business — which, on paper, is most of what looking established amounts to.

How these tools work
Every one of these 13 tools runs entirely in your browser. There is no account to create, no file to upload and no daily limit, because the work happens on your own device rather than on a server — which also means there is nothing for us to log, cache or leak. Most of them keep working with the network off once the page has loaded.
