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.
