# Invoice vs receipt

**An invoice is a request for payment; a receipt is proof of payment.** The invoice comes first and asks for money owed; the receipt comes after and confirms money paid.

## How it works

- An invoice lists what's owed, the terms (e.g. [Net 30](/glossary/net-30/)) and a due date — it creates an [accounts receivable](/glossary/accounts-receivable/) entry.
- A receipt is issued once payment clears, acknowledging the transaction is settled.
- Same transaction, two documents, two moments: obligation, then discharge.

One asks; the other confirms. Mixing them up muddles what's actually been collected.

## Why it matters

For bookkeeping, the distinction is the difference between "billed" and "paid" — revenue you're owed versus cash you hold. Customers need receipts for their own records and tax claims, and businesses need invoices to prove and chase what's due. Sending a receipt when you meant an invoice can quietly signal a bill as settled when it isn't.

## How Fynex does it

Fynex issues invoices with branded payment links, then auto-reconciles each payment and posts it back to your books — so the "paid" confirmation is automatic, not a second document you chase. See [Invoicing & Collections](/features/invoicing/).
