Invoice vs. receipt: what's the difference?

Updated 2026-06-18

People often use “invoice” and “receipt” interchangeably, but they play completely different roles in a transaction: one asks for money, the other confirms money was received. Mixing them up leads to messy books and, worse, problems with tax and reimbursement.

The difference in one line

  • Invoice: issued by the seller before payment, telling the buyer how much to pay and when. It’s a request for payment.
  • Receipt: issued by the seller after payment is received, confirming the money arrived. It’s proof of payment.

The timeline is simple: invoice first → buyer pays → receipt afterwards.

What each should include

An invoice emphasises what’s owed:

  • Invoice number, issue date and due date
  • Seller and buyer details
  • Line items, quantities, unit prices and amounts
  • Subtotal, tax and total due
  • Payment method and terms

(See the full checklist in what to include on an invoice.)

A receipt emphasises that payment was made:

  • Receipt number and payment date
  • Seller and buyer details
  • A summary of what was bought
  • Amount paid and payment method
  • Usually marked “PAID”

When to use which

  • Delivering goods or services and asking to be paid → issue an invoice.
  • After the buyer pays and needs proof (for their records or expenses) → issue a receipt.
  • In some instant-sale situations, a receipt alone is enough — no separate invoice needed.

What about a pro forma invoice?

A pro forma invoice is a quote-like document sent before the real invoice — used to confirm an order or arrange prepayment. It isn’t a formal receivable; you issue the actual invoice once the deal is confirmed.
