Invoice vs. receipt: what's the difference?
In short: an invoice asks your customer to pay; a receipt confirms that they have paid.
| Invoice | Receipt | |
|---|---|---|
| Purpose | Request payment | Proof of payment |
| When it's sent | Before payment (after the work or sale) | After payment |
| Key dates | Invoice date and due date | Payment date |
| Shows | Amount due, payment terms and how to pay | Amount paid and how it was paid |
| Typical number format | INV-0001 | RCPT-0001 |
When to use which
- You did the work and haven't been paid yet → send an invoice.
- The customer paid on the spot, or paid an invoice and wants confirmation → give a receipt.
- A client asks “how much will this cost?” before you start → send an estimate or quote.
Can a paid invoice work as a receipt?
Many businesses mark an invoice “Paid” and send it again as confirmation, and many customers accept that. A separate receipt with the payment date and method is clearer, especially for customers who need it for their own records or expense claims.
In Slipfold you can do either: mark an invoice as paid (it shows a PAID label and the payment date), or create a receipt.
Or start with an invoice — you can switch the document type at the top of the editor.
