Although invoices and receipts are both important financial documents, they serve different purposes in a transaction.
What is an invoice?
An invoice is a document sent by a seller to request payment for goods or services provided. It outlines what has been supplied, how much is owed and when payment is due.
Invoices are typically issued before payment is made.
An invoice usually includes:
- Invoice number
- Description of goods or services
- Quantity and price
- Payment terms and due date
- Seller and buyer details
- Applicable taxes or VAT
Example
A marketing agency completes a project and sends a client an invoice for £5,000 payable within 30 days.
What is a receipt?
A receipt is a document that confirms payment has already been made. It acts as proof of payment for the buyer and a record of completed payment for the seller.
Receipts are issued after payment is received.
A receipt usually includes:
- Receipt number
- Amount paid
- Payment date
- Payment method
- Details of the goods or services purchased
- Seller information
Example
After paying the £5,000 invoice, the client receives a receipt confirming the payment has been processed.
Key differences between an invoice and a receipt
| Invoice | Receipt |
|---|---|
| Requests payment | Confirms payment |
| Issued before payment | Issued after payment |
| Shows amount owed | Shows the amount owed |
| Used for accounts receivable | Used as proof of purchase |
| May include payment terms | May include payment method |
Why both documents matter
- Invoices help businesses track money owed and manage cash flow
- Receipts provide proof of payment for accounting, tax and record-keeping purposes
- Together, they create a clear financial trail for both buyers and sellers
In simple terms, an invoice asks for payment, while a receipt confirms that payment has been made.
