A one-off invoice, any trade or profession
Fill in a form, watch the invoice build up as a live preview, then download it as a PDF - business and client details, line items, tax, and a running total. Not tied to construction - built for any trade, freelancer or small business.
A live invoice preview sits next to the form - business details, client details, line items and totals all update as you fill them in, not a separate "preview" step.
GBP, USD, EUR, AUD, CAD or NZD, with a custom tax/VAT rate - generic by design, not tied to construction pricing or a specific trade.
Download a clean, ready-to-send PDF invoice - generated entirely on your device, with nothing about your business or client data uploaded anywhere.
Add or remove line items freely - description, quantity and unit price - with the subtotal, tax and total recalculating as you go.
A free-text notes field for payment terms, bank details or anything else that needs to appear on the invoice itself.
A light/dark toggle that remembers your choice, and a rotating set of realistic sample invoices across different trades and currencies to load and explore.
