Invoice vs estimate: when to use each
An estimate (also called a quote) and an invoice sit at opposite ends of a job. One sets expectations before you start; the other collects payment once the work is done. Using the right one at the right time avoids awkward conversations about money.

An estimate is a proposed price you send before work begins, so the client can decide whether to go ahead. An invoice is a request for payment you send after the work is agreed or delivered. An estimate is not a demand for money; an invoice is.
How an estimate becomes an invoice
When a client accepts your estimate, the numbers usually carry straight over to the invoice. Rather than retyping everything, SafeKit lets you convert an accepted estimate into an invoice — the same items, prices and customer, with a fresh invoice number and dates.
What to include on an estimate
- A clear label — “Estimate” or “Quote” — and a reference number
- An expiry or “valid until” date, since prices can change
- The same line-item detail an invoice would have
- Any assumptions or exclusions, so the scope is clear
