Quick answer
An invoice requests payment for goods or services, while a receipt confirms that payment has been received. Nigerian businesses should issue invoices before or at payment request and receipts after payment confirmation.

How they differ
An invoice tells the customer what is owed, when it is due and how to pay. A receipt proves that the customer paid.
For part payments, the invoice can remain open while receipts show each payment received.
- Invoice number
- Due date
- Amount owed
- Payment terms
- Receipt number
- Amount paid
- Payment date
Why records matter
Good records help with refunds, disputes, business loans, tax preparation and customer trust. If a customer says they paid, a receipt and bank confirmation help settle the issue quickly.
For bank transfer payments, save transaction references alongside the receipt.
Common mistakes
Do not mark an invoice as paid until payment is confirmed. Do not issue vague receipts that omit customer name, amount or date.
If VAT or tax applies to your business, handle it clearly and consistently.
