Invoice vs receipt: the difference
By Diljit Ramachandran, founder of The Invoice Generator. Published Oct 26, 2026.
An invoice asks for money that is owed; a receipt confirms that money was received. The seller sends the invoice first and gives the receipt after the payment arrives. They are not the same document.

What is the difference between an invoice and a receipt?
An invoice is a request for payment. A receipt is proof of payment.
| Invoice | Receipt | |
|---|---|---|
| Purpose | Asks for payment | Confirms payment |
| When | Before payment | After payment |
| Shows | What is owed and by when | What was paid, when and how |
| Number | Its own invoice number | Its own receipt number, often quoting the invoice number |
Is an invoice a receipt?
Not by itself. An invoice marked paid can serve as a receipt in many cases, but some clients still ask for a separate one. A receipt costs nothing to give; see how to write a receipt.
When do you need each?
Send an invoice when payment comes later. Give a receipt when money is paid, especially cash. For a small sale paid on the spot, a sales receipt alone is often enough (a paper receipt book is covered in how to fill out a receipt book), though a business buyer may still want an invoice.
Questions
- Can one document be both an invoice and a receipt?
- A paid invoice with the date and method of payment written on it can, in many places. Check any local rule that asks for a separate receipt.
- Which should I keep for my records?
- Both. The invoice shows what was billed and the receipt shows it was paid.
