Invoice vs receipt
Free Invoice GeneratorPublished 2 March 2026 4 min read
An invoice requests payment and is issued before payment is made; a receipt confirms payment and is issued after. The invoice creates the obligation and states what is owed and by when; the receipt is proof that the obligation was settled. Most transactions generate both.
| Invoice | Receipt | |
|---|---|---|
| Purpose | Requests payment | Confirms payment |
| Issued | Before payment | After payment |
| Key fields | Due date, payment terms, amount due | Amount paid, payment date, method |
| Used by buyer for | Approving and scheduling payment | Proving the expense |
| Used by seller for | Accounts receivable | Closing out the receivable |
Where the confusion comes from
In retail the two collapse into one document: you pay at the till and receive a receipt, with no invoice in between, because there was never a period during which money was owed. In B2B they stay separate, because the gap between delivery and payment is exactly where the invoice does its work.
Related documents worth distinguishing
- Quote / estimate — a proposed price before work is agreed. Not a payment request, and not binding in the way an invoice is.
- Proforma invoice — a preview of an invoice, often used to obtain approval or arrange payment in advance. It is not a tax invoice and should not be entered as one.
- Credit note — reverses all or part of an invoice already issued, referencing the original number.
- Statement — a summary of all outstanding invoices for a customer, not a payment request for a single transaction.
