What is an invoice?
An invoice is a payment request. It usually includes invoice number, date, due date, seller details, customer details, item rows, taxes, total amount, and payment terms.
Small businesses use invoices when they want a customer to pay later, pay by a due date, or keep a formal billing record.
What is a receipt?
A receipt is proof that payment was received. It usually includes receipt number, payment date, customer details, paid items, total amount, and a paid status.
A billing receipt is useful after a customer pays an invoice, bill, advance booking, or service charge.
What is a bill?
A bill shows the amount the customer should pay. In casual business use, a bill and invoice can overlap, but an invoice is usually more formal and easier to track.
If the customer has already paid, use a receipt instead of calling the document a bill.
Which one should you send?
- Send an invoice when the customer still needs to pay.
- Send a bill for a simpler amount-due document or checkout-style payment request.
- Send a receipt after payment is complete.
- Send a quotation or estimate before the customer approves the order.
