A sales invoice requests or records the amount a customer owes for a sale, while a receipt confirms that payment has been received.
Send an invoice before or at the point payment becomes due, then provide a receipt or clear paid status after the money is collected and reconciled.
Invoice vs receipt at each stage of a sale
| Question | Sales invoice | Sales receipt |
|---|---|---|
| Who creates it? | The seller requests or records payment from the buyer | The seller or payment system confirms money received |
| When? | Before payment, at the billing event, or under credit terms | At or after payment |
| What amount? | Total amount, tax, prior payment, and balance due | Amount and method actually paid, plus any balance |
| Key reference | Invoice number and due date | Receipt or payment reference linked to the invoice |
| Main evidence | Goods or services billed and payment terms | Proof of payment |
Can an invoice be used as a receipt? A paid invoice can help if it clearly records the payment date, amount, method, and remaining balance, but an unpaid invoice is not proof of payment. Invoices and receipts can sit in one workflow: use an invoice to request payment and issue a receipt or paid confirmation after the transaction reconciles.
A sales receipt may also function as proof of purchase, but customer rights, tax evidence, and warranty requirements vary. Keep the invoice, processor or bank record, and receipt connected rather than expecting one document to prove every fact.
Show the remaining balance after payment
Suppose the customer pays $400 against a $1,200 invoice. The receipt should identify the $400 payment and the invoice it settles; the invoice balance remains $800. Marking the entire invoice paid would hide the amount still owed. For a fully paid sale, a combined invoice and receipt can be useful if the document clearly distinguishes the charge from the payment received.
Example
A consultant issues a $1,200 invoice with Net 15 terms on 1 August and sends a receipt on 10 August after the bank transfer is matched.
What to watch for
A paid invoice can help prove payment only if it clearly records the payment, but an unpaid invoice is not a receipt and a receipt does not always contain tax-invoice details.
