Basics
Invoice vs receipt: what's the difference?
People often use the words "invoice" and "receipt" interchangeably, but they do two different jobs. Getting them right makes you look professional and keeps your records clean.
An invoice is a request for payment
You send an invoice before you've been paid. It says, in effect, "here's what you owe and when it's due." An invoice lists the work or products, the amount, and the payment terms. It's the document that starts the payment clock.
A receipt is proof of payment
You send a receipt after payment has been made. It confirms, "you paid this amount on this date." A receipt usually shows the same line items as the invoice, plus the payment method and a clear PAID marker. Your client keeps it as proof for their own records or taxes.
Quick comparison
- Timing: Invoice comes first (before payment); receipt comes after.
- Purpose: Invoice requests money; receipt confirms money was received.
- Key detail: Invoice shows a due date; receipt shows the payment method and marks the total as paid.
Do you need both?
For most transactions, yes. Send an invoice to request payment, then send a receipt once the client pays. It's good practice and clients appreciate it — especially businesses that need the receipt for their bookkeeping.
