Invoicing basics

Invoice vs Receipt: What's the difference?

An invoice is a request for payment. A receipt is proof that payment has happened. Same transaction, two different documents — issued at different moments and serving different legal purposes.

TL;DR

An invoice is issued before payment to ask for it. A receipt is issued after payment to confirm it. The invoice goes into accounts receivable; the receipt is the record of cash actually received.

Invoice

Asks for payment — issued before money changes hands

An invoice is a commercial document a seller issues to a buyer that itemizes goods or services delivered, the agreed price, taxes, and the amount and deadline for payment. It is the legal trigger for accounts receivable on the seller's side and accounts payable on the buyer's side.

Receipt

Confirms payment — issued after money has been received

A receipt is a written acknowledgement that the buyer has paid (in full or in part) for the goods or services. It is proof of payment for the buyer, supports expense reporting, and discharges the obligation recorded by the invoice.

Frequently asked questions

Can the same document be both an invoice and a receipt?

Yes. When payment is collected at the moment of sale (Due on Receipt) the document can serve both functions, often labelled as a 'paid invoice' or a 'sales receipt'. Software like Stripe and Shopify generate paid-status invoices that double as receipts.

Is an invoice proof of payment?

No. An invoice is proof that payment is owed. Only a receipt (or a bank/Stripe payment record marked 'paid') is proof that payment has actually been received.

Do I need to send a receipt if I already sent an invoice?

Best practice is yes. Sending a receipt — or marking the invoice as 'PAID' and re-sending it — closes the loop, gives the buyer something to file for their books, and reduces follow-up emails asking 'did you receive my payment?'

Which one do I keep for taxes?

Sellers keep invoices to support output VAT/sales-tax filings; buyers keep receipts to support expense and input-tax claims. In many jurisdictions you should keep both for at least 5–7 years.
