Invoice vs. Receipt
An invoice is a request for payment, sent before or when the money is owed. A receipt is proof that payment already happened. If a client asks for a receipt before they’ve paid, what they actually need is an invoice.
What it means
The two get swapped constantly in conversation, but a bank, an accountant, or the tax office cares about the difference. An invoice says “you owe me $400, due by this date.” A receipt says “you paid $400 on this date” — proof of a completed transaction, not a request for one.
Most small jobs only need the invoice — once it’s paid, marking it paid is usually enough of a record. A separate receipt matters more for cash payments, where there’s no bank statement backing up that the money changed hands, or when a client specifically needs one for their own expense records.
A client pays cash for a $150 repair. You’ve already given them the invoice, but they ask for “something showing I paid.” You issue a receipt referencing that invoice number, dated the day of payment — now they have proof for their own records.
Sending an invoice and calling it a receipt in the email — harmless until a client’s accountant asks for an actual receipt and you have to explain the invoice they filed doesn’t count as one.
