Invoice vs Receipt: What's the Difference (and When to Send Each)?

Invoice vs receipt confuses a surprising number of new business owners, and the mix-up creates real accounting headaches later. This guide untangles the two documents.

Short answer

An invoice requests payment. A receipt confirms payment received. Both can describe the same transaction — the invoice comes first, the receipt comes after money has moved.

What an invoice does

An invoice is a legal request for payment. It creates an account-receivable on your books and an account-payable on your client's. It must show what was sold, at what price, to whom, and by when payment is due.

What a receipt does

A receipt acknowledges that payment has been received. It closes the account-receivable and is the document a client keeps for expense reporting, tax deduction, or warranty claims.

When to send each

• Send an invoice when work is delivered or goods are shipped, and before payment.
• Issue a receipt immediately after payment clears, even if the client did not ask.
• For in-person cash sales, the receipt often replaces the invoice entirely.

The same tool creates both

In our invoice generator you create the invoice, share it, and once the client pays you flip the status to Paid. The same document becomes the receipt: it now shows Paid and the payment timestamp, and you can download that as PDF for the client.
