Invoice vs Receipt
An invoice is a request for payment issued before or while money is owed. A receipt is proof that a payment was received. One transaction may need both: the invoice establishes the amount due, and the receipt records the later payment.

When to send an invoice
Send an invoice when a customer owes money for goods or services. Identify the transaction, seller, customer, issue date, line items, taxes where applicable, payment terms and balance due. The exact required fields depend on the business and jurisdiction.
Do not mark an invoice paid merely because it was sent. Update the balance only when payment clears or is otherwise confirmed.
When to issue a receipt
Issue a receipt after receiving money. State the date, amount, payment method, payer, seller and what the payment covered. For a partial payment, identify the related invoice and show the remaining balance.
A receipt is useful evidence, but it is not a substitute for the original itemization, contract or invoice. Retain documents together using a stable reference number.
Example lifecycle
A designer sends invoice INV-1042 for $1,200 due August 15. The client pays $600 on August 5, so the designer records the partial payment and issues a $600 receipt referencing INV-1042. After the remaining $600 clears, a final receipt confirms that the invoice balance is zero.
