About

Own Boss Tools is a collection of free calculators and document templates for people who run their own work: tradespeople, online sellers, freelancers and creators.

Every tool runs entirely in your browser. Nothing you type is sent to a server, and files you load into a tool never leave your computer.

The site is built and maintained by an independent developer and is supported by advertising. Fee schedules and formulas are checked against the source they are based on and the date of the last check is shown on each tool. If you find an error, tell us.

Results are estimates for planning. Confirm anything that matters with the marketplace, supplier or professional involved.
