Key takeaways
- An invoice is issued before payment and asks for it. A receipt is issued after payment and confirms it.
- The invoice is the document for tax records and for matching to a purchase order. The receipt is proof the debt is settled.
- For expense claims and audits, keep both, linked by invoice number.
- A paid invoice marked as paid is sometimes used as a receipt, but a separate receipt is safer.

The difference in one sentence
An invoice is a request for payment issued by a seller. A receipt is the seller's confirmation that payment has been received.
The order matters. The invoice comes first, before the money moves. The receipt comes second, after the money has arrived. If you have only a receipt, you can prove you paid. If you have only the invoice, you can prove what you owed, but not that you paid.
A buyer pays a supplier's invoice for 6,400 by bank transfer on the 12th. The supplier's system applies the cash on the 13th and sends a receipt that cites the invoice number, the payment date and the amount.
Six months later an auditor asks the buyer to show that invoice 3017 was paid. Finance pulls up the invoice, the bank line and the receipt together. The check takes two minutes.

Which one do you need
- To claim tax credit on a purchase: the tax invoice, where tax rules require one.
- To prove a bill was paid: the receipt, a bank statement line or proof of payment.
- To tell the seller what you paid: a remittance advice.
- To file an employee expense claim: the receipt, often with the invoice.
- To book a purchase: the invoice, matched to the purchase order and goods receipt.
The seller's version of the receipt is covered on payment receipt. For a seller's quoting stage see quote versus invoice.
Mistakes
- Paying twice because a duplicate invoice looked like a new request.
- Filing a receipt as the tax record when only the invoice carries the tax details.
- Accepting a screenshot as a receipt without the invoice reference.
- Marking an invoice paid before the cash is applied.
- Losing the link between the two documents.
- Invoice with its number and date.
- Receipt or payment confirmation with the invoice reference.
- Bank line with the same amount.
- Purchase order and goods receipt if goods.
- Credit notes that adjusted the amount.

Frequently asked questions
Is a receipt the same as an invoice?
No. An invoice requests payment. A receipt confirms it was paid.
Can an invoice serve as a receipt?
An invoice stamped paid, with the payment date and method, is sometimes accepted as a receipt. A separate receipt is safer.
Which document do I need for tax?
Usually the tax invoice supports a tax credit, while the receipt supports proof of payment. Check local rules.
Who issues a receipt?
The seller, or the payment system or bank when the payment is made online.
Do I need both for an audit?
Yes, as a pair, along with the bank line. Link them by invoice number.
