Invoice vs Receipt: What's the Difference (and When to Use Each)

Both documents list items and amounts. Both often look nearly identical in template form. But they're issued at opposite ends of a transaction, and mixing them up creates real problems — for your books, and for whoever you send it to.

An invoice is a request for payment

You send an invoice before money changes hands. It says: here's what I supplied, here's what it costs, here's when payment is due. It's a legal record of a debt owed to you, and it's what your buyer uses to plan their payables.

A receipt is proof payment already happened

You send a receipt after you've been paid. It confirms the amount received, the date, and the payment method. It's what the buyer keeps as proof of purchase — for expense claims, warranty support, or their own records.

Why the mix-up matters

If you send a "receipt" for money that hasn't arrived yet, you've created a document that falsely states payment was made — which causes real reconciliation errors on both sides of the transaction, and can misstate your revenue if it gets logged as paid before it actually is.

A simple rule: if you're still waiting to be paid, it's an invoice. If the payment already landed, it's a receipt.

Quick reference

• Invoice — sent before payment, states an amount owed, includes a due date
• Receipt — sent after payment, confirms an amount received, includes a payment method
