Invoice One

Invoices & estimates

Send a quote, get it accepted, bill it

A job usually starts with a number, not an invoice. Invoice One writes that number as a proper estimate, tracks the answer, and turns the yes into an invoice without you typing anything twice.

Quote before you commit

An estimate is built exactly like an invoice — same items, same tax, same templates — but it asks instead of demands. Add an expiry date and it marks itself as expired when the date passes.

Accepted or declined, on the record

Mark what the client said. Accepted estimates wait to be billed, declined ones stay in the list so you can see what you quoted and what came of it.

One tap from yes to invoice

Converting copies every line, the tax lines and the client across, gives the new document the next invoice number, and leaves the estimate linked to it. Nothing is retyped, nothing drifts.
