Estimate vs. Invoice: What's the Difference?

An estimate (or quote) is what you send before the work to win the job. An invoice is what you send to get paid — either after the work is done, or for a deposit up front.

When to send an estimate

Send an estimate when a customer is shopping or you haven't agreed on price yet. It should show the scope of work, a price breakdown, how long it's valid, and any deposit required to schedule.

When to send an invoice

Send an invoice once work is agreed or completed. It includes a due date, payment terms, and a balance due. If you collected a deposit, the invoice should show it as already paid.
