Invoice vs Receipt vs Quote: Differences

Facts last checked October 24, 2026

Quotes, invoices and receipts are easy to mix up, and sending the wrong one causes real confusion. They are three different documents that usually appear in a fixed order during a single job. This guide explains each, and how they fit together.

The short version

Document What it says When you send it Who it helps
Quote “This is what the work will cost.” Before the work starts The client, to decide
Invoice “You owe this amount for work done.” After the work or goods You, to get paid
Receipt “Payment received, thank you.” After you have been paid The client, as proof of paying

Quote

A quote is an offer. You say what you will do and what it will cost, so the client can decide whether to go ahead. A good quote lists what is included, the price, how long the offer is valid, and any conditions, such as a deposit or a limit on revisions.

People sometimes use “quote” and “estimate” to mean the same thing, and sometimes not. In general, a quote is meant to be a firm price, while an estimate is a best guess that can change. Whichever word you use, say clearly whether the figure is fixed. Whether a quote is legally binding depends on your country and on what was agreed, so ask for advice if it matters.

Invoice

An invoice asks for payment. It lists what was delivered, the amounts, any tax, the total and when payment is due. It is the document you use to get paid, and it is the record your accounts and your client’s accounts rely on. If you are registered for a sales tax, an invoice may also have to meet your tax authority’s rules; see what to include on an invoice.

You can send one invoice for the whole job or several: for example, a deposit invoice at the start and a final invoice at the end.

Receipt

A receipt confirms that payment has been made. It says who paid, how much, when and for what, and often refers to the invoice it settles. A receipt is proof for the client that they paid, which they may need for their own accounts or a refund.

Not every sale needs a separate receipt. Some businesses mark the original invoice as “Paid” and send it back, which serves as both. Whether you must give a receipt, and what it must contain, depends on your country and the type of sale.

How they fit together

Imagine a photographer booked for a wedding.

  1. Quote: the photographer sends a quote for $1,800 covering eight hours and an album, valid for 30 days.
  2. Invoice 1: after the client accepts, an invoice for a $500 deposit.
  3. Receipt: when the deposit arrives, a receipt for $500.
  4. Invoice 2: after the event, an invoice for the $1,300 balance, referring to the deposit already paid.
  5. Receipt: when the balance arrives, a final receipt.

The same flow works for most freelance and small-business jobs.

Other documents you may meet

  • Proforma invoice: a preliminary invoice sent before the goods or services are delivered. It is not a final bill. It is often used in international trade for customs or so the buyer can arrange payment in advance.
  • Credit note: a document that reduces or cancels an invoice you have already issued, for example because of a return or a mistake. It refers to the original invoice number.
  • Statement: a summary of all invoices and payments with one client over a period, showing what is still owed.
  • Purchase order: a document the client sends you, asking you to supply something at an agreed price. You then invoice against it.

Which should you send?

  • Need the client to say yes? Send a quote.
  • Need to be paid? Send an invoice.
  • Client paid and wants proof? Send a receipt, or mark the invoice as paid.
  • Made a mistake on an invoice you have already sent? Send a credit note, then a new invoice.

What not to do

  • Do not call a quote an invoice. A client may pay too early, or reasonably refuse to.
  • Do not send an invoice without a number or due date. See how to write an invoice.
  • Do not create documents that misstate what happened. A receipt must reflect a payment that was really made. Making false records is illegal in most places.
