How this tool works
A company name, a client name and a row per line item — description, quantity and rate — are laid out as an invoice and written directly into a real, downloadable PDF. It is a clean statement of charges rather than an accounting system, and knowing what it does not do is what stops an invoice going out wrong.
Each row's amount is quantity multiplied by rate, calculated as you type rather than entered by hand, and the invoice total follows automatically. Rows can be added, removed and reordered; today's date is stamped as the invoice date and the invoice number is generated for you rather than typed. Paper size ranges from A4 down to a 48 mm thermal receipt roll, which switches the whole layout to a centred receipt rather than shrinking the sheet.
Getting the total right
- Quantity defaults to one: leave it as it is for a flat-rate line, or set it for anything billed per hour, per unit or per item — the amount updates as soon as either number changes.
- Pasting several lines still works: paste a multi-line list into any description field and each line becomes its own row — "description, rate" or "description, quantity, rate", one item per line.
- Add tax as its own row: the total is the sum of every row's amount. Where you charge VAT or a sales tax, add it as a visible line or state clearly that your amounts include it.
- Say which currency it is: the symbol you pick is used throughout, but it is not spelled out in words anywhere on the page — add a line stating the currency if there is any chance of doubt.
