Quote vs. Invoice vs. Receipt: What's the Difference?

These three documents show up at three different moments in the same job, and mixing them up (sending a "quote" that reads like a bill, or an "invoice" a client mistakes for a receipt) causes real confusion. Here's the difference between a quote, an invoice, and a receipt — and when to use each one.

What is a quote?

A quote (or estimate) comes before the work starts. It's your proposed price for a job the client hasn't agreed to yet — a way of saying "here's what I'd charge to do this," so the client can decide whether to move forward. A quote is not a request for payment; nothing is owed yet.

Some businesses distinguish "quote" (a firm, fixed price) from "estimate" (a rough, non-binding figure that might shift once the full scope is known) — worth clarifying which one you're sending if the job has any uncertainty in scope.

What is an invoice?

An invoice comes after the work is done (or partway through, for larger jobs billed in stages). It's a formal request for payment — this is what you actually did, this is what it costs, this is when payment is due. Unlike a quote, an invoice represents money the client now owes.

What is a receipt?

A receipt comes after payment is received. It confirms the money changed hands — proof of purchase for the client's own records (expense tracking, taxes, warranty claims), and proof for you that the invoice is settled.

The order these happen in

For a typical job, the sequence is:

1. Quote — "here's what I'd charge" (before work starts, no payment involved)
2. Invoice — "here's what you owe" (after work is done, payment requested)
3. Receipt — "here's confirmation you paid" (after payment is received)

Skipping steps causes the confusion mentioned above — sending an "invoice" before any work has happened reads as presumptuous (you're billing for something not yet done), and never sending a receipt leaves a client without a paper trail for their own records.

Do you always need all three?

For small, simple jobs, quote and invoice sometimes collapse into one document (you agree on price verbally, then the "invoice" is really the first formal paperwork). But for anything with real scope — remodels, ongoing service contracts, larger creative projects — keeping all three distinct protects both sides: the client has a clear record of what was agreed to versus what was actually billed, and you have a paper trail if a dispute ever comes up.

One tool, all three: Featherwork turns a quote into an invoice with two clicks once a job's approved, and every paid invoice doubles as a receipt automatically.
