About the Invoice Generator
Build a proper invoice — line items, quantities, tax, totals — and send it as a PDF. The difference between this and a free invoice builder is memory: your clients, your invoice numbering and what is still unpaid are all kept, so the next invoice takes a minute instead of starting from a blank page.
Money handling
Amounts are stored as integers in the currency's minor unit rather than as floating-point
numbers. That is deliberate: 0.1 + 0.2 is famously not 0.3 in
binary floating point, and an invoice that is a penny out is a document nobody trusts.
The free plan keeps five invoices; Pro is effectively unlimited.
Can I send the invoice to a client?
Yes — invoices render to PDF, which is the format every client and accountant expects.
Does it track what has been paid?
Unpaid totals are kept alongside each client, so the dashboard answers “who owes me what” without you rebuilding a spreadsheet.
Are invoice numbers sequential?
Numbering is remembered between invoices, so you are not left guessing which number you used last.
Can I add tax?
Yes, tax is applied to the invoice and included in the totals on the PDF.
Frequently asked questions
What does Invoice Generator do?
Professional invoices with saved clients, sequential numbering and PDF export. It runs on ToolMunch's own API, so the result comes back to the page with nothing to install.
Is Invoice Generator free to use?
Yes. Invoice Generator is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
Do I need to create an account or sign up?
No. There is no account, no email address, and no login. Open Invoice Generator, do the job, and take the result — nothing is gated behind a signup form.
Where is the work done?
Invoice Generator sends what you give it to ToolMunch's own API, does the work there, and returns the result to your browser. It is used to answer that one request — it is not sold, shared, or added to an advertising profile.
Does Invoice Generator work on Mac, Windows, and phones?
Yes. Invoice Generator runs in any modern web browser on Windows, macOS, Linux, Chromebook, Android, and iOS. There is nothing to download or install.
Will the result have a watermark?
No. ToolMunch never adds a watermark, a badge, or a trailing page to anything you make here. What you get back is what you made.
