Invoicing

Invoice vs Quote: What's the Difference?

Quotes and invoices bookend every job: the quote sets the price before the work, and the invoice collects the money after. Confusing the two confuses your client — and your records.

The quote comes first

A quote is a firm offer: 'this is what I'll do, and this is exactly what it will cost.' It's sent before work begins, usually with a validity period. Once the client accepts, the price is generally binding — which is why quotes should be detailed and carefully priced.

The invoice comes after

The invoice requests payment for work done (or in progress, for staged billing). It references the same items as the accepted quote, adds payment terms and a due date, and is the document your client actually pays against.

Estimates sit between the two

An estimate is a ballpark figure — an informed guess that can change as scope becomes clearer. Unlike a quote, it's not a promise. Many clients say 'quote' when they mean 'estimate'; confirming which one you're providing prevents pricing disputes later.

Connecting them

The cleanest workflow: send a quote, get approval, then convert that quote into an invoice with the same line items. Invoala does this in one click — the items carry over and a due date is added automatically. No retyping, no transcription errors, and the numbers the client approved are exactly the numbers they're billed.

Example

A web designer quotes $3,000 for a site rebuild with 30-day validity. The client approves on day 12. The designer converts the quote to an invoice with Net 14 terms — same $3,000, now with a payment deadline.

Frequently asked questions

Is a quote legally binding?

An accepted quote is generally a binding agreement at the quoted price. Estimates are not. Label your documents clearly so there's no doubt about which one you sent.

Can I change the price after a quote?

Only if the scope changes or the quote expired. Changing the price of an accepted quote without scope change is a fast way to lose trust — and potentially a dispute.

Should quotes have payment terms?

Quotes usually show a validity period rather than payment terms. Payment terms belong on the invoice you raise after acceptance.
