Cleanbill started from a simple frustration: every free invoice tool either plastered a watermark on your PDF, locked the useful features behind a subscription, or crashed when you tried to add a logo. We wanted something that just worked — clean, fast, and free without the asterisk.
We're a small team of builders and freelancers who invoice clients ourselves. That means we've personally run into every invoicing headache the tool is designed to solve: manually recalculating totals, reformatting a Word template that shifted when opened on a different machine, chasing clients who couldn't figure out how to pay from a PDF with no payment instructions.
Cleanbill is our answer to that. It handles the formatting, the math, the currency symbols, and the PDF generation — so you can focus on the work, not the paperwork. It's free forever, with no watermarks and no sign-up required to get started.
The tool supports 8 invoice templates, 25+ currencies, custom branding (logo, colour, font), automatic tax and discount calculations, and webhook automation for connecting to tools like Make.com and Zapier. Everything runs in your browser — no data is sent to any server unless you explicitly use the webhook feature, and your draft is saved locally so you pick up exactly where you left off.
We also publish practical, no-fluff guides on invoicing — how to write payment terms, how to invoice as a freelancer, what the difference between an invoice and a receipt actually is. If you're new to billing clients, the blog is a good place to start.
Questions, feedback, or a bug to report — we read everything. Reach us at contact@cleanbill.llc. If something isn't working the way it should, tell us exactly what you were trying to do and we'll look into it.
Free, no sign-up required to get started.
