Most invoice tools assume one country, one currency and one tax rule. Freelance work has not looked like that for a decade.
Each currency formats the way its own market expects. Bitcoin, Ethereum, USDT, USDC, Solana and Monero are handled at proper decimal precision instead of being squeezed into two places.
List as many wallets as you accept alongside your bank details. They print as selectable text, so a client can copy an address straight out of the PDF without retyping it.
No tax, a single rate, or a different rate on every line. Prices can be tax-exclusive or tax-inclusive, which is the difference between a correct and an incorrect VAT invoice.
Send a German client a Rechnung and a Brazilian client a Fatura from the same file. Only the printed labels change — your own wording stays exactly as you typed it.
Choose Arabic or Persian and the whole document flips: columns, totals, the paid stamp, all of it. Not a mirrored afterthought.
Classic sets the document in a serif for a formal, printed feel. Modern is clean and contemporary. Compact fits long itemised jobs on one page. Typed is monospaced and plain. Eight accent colours and your own logo.
Save a client once and fill their details in with one click next month. Duplicate last month's invoice and change two numbers — retainer billing takes under a minute.
Record a deposit already received and the document shows the balance due underneath the total, the way a client expects to read it.
A single JSON file backs up everything for a new computer. A CSV export lists every document with its total, ready for a spreadsheet or your accountant at year end.
No installer, no npm, no build step, no framework. One file you can read, edit and keep. Adding a currency or a language is a two-line change, and the README shows you exactly where.
Download it, open it, and send your first invoice in the next five minutes.
