Free business tools, built for the people running their own show.
FreeAdminTools.com is a collection of free, no-nonsense business tools built for freelancers, contractors, and small business owners. Every tool on this site is completely free to use — no account required, no email address, no subscription.
We focus on the everyday administrative tasks that take up time but don't need to: writing invoices, calculating overtime pay, figuring out what to charge, understanding your margins. These are problems every self-employed person runs into, and they shouldn't require expensive software to solve.

More tools are in the works. If there's something you'd like to see, we'd love to hear about it.
Every tool on this site is completely free with no hidden limits. We don't cap the number of invoices you can create, require you to upgrade to download a PDF, or put key features behind a paywall. The site is supported by advertising, which keeps the tools free for everyone.
We don't ask for your name, email address, or any personal information to use these tools. Everything runs in your browser — your data never leaves your device. We can't see your invoices, your rates, or your business information because it's never sent to our servers.
These tools are designed for people who are great at their craft but didn't necessarily sign up to be accountants or HR managers. We aim to make each tool self-explanatory — if you need to read a manual to use an invoice generator, something has gone wrong.
Have a question, a suggestion for a new tool, or found a bug? We'd love to hear from you.
