Invoice generator for small business.

Not every business needs invoicing software. If you send a handful of invoices a month, Mono Invoice. does the job without subscriptions, onboarding, or another login to manage.

Professional output, zero overhead

Add your logo, set your brand color, and choose one of three clean templates. Line items, quantities and rates total automatically, with tax and discount applied correctly — so every invoice goes out accurate and consistent.

Works for international billing

More than 35 currencies with correct local formatting, including USD, EUR, GBP, CHF and the Nordic currencies. Issue and due dates, payment details, and notes are all built in.

Your numbers stay yours

Mono Invoice. runs entirely in the browser. Client names, amounts, and payment details are never uploaded to a server — useful when you'd rather not hand your billing data to another vendor.
