Invoice vs Receipt - What's the Difference?
One comes before payment, the other comes after.
Updated March 9, 2026 by invoice.Now.
Invoice: A Request for Payment
An invoice is a document sent by a seller to a buyer requesting payment for goods or services. It is issued before payment has been made. The invoice specifies what was provided, how much is owed, and when payment is due.
An invoice typically includes:
- Seller's and buyer's contact details
- Invoice number and date
- Itemized list of products or services
- Total amount due
- Payment terms and due date
- Accepted payment methods
Receipt: A Confirmation of Payment
A receipt is a document issued after payment has been received. It serves as proof that the transaction is complete. The buyer keeps the receipt for their records, and the seller keeps a copy for theirs.
A receipt typically includes:
- Seller's name and contact details
- Date of payment
- Description of what was purchased
- Amount paid
- Payment method used
- Reference to the original invoice number (if applicable)

When to Use Each
Send an invoice when you have completed work or delivered goods and need to collect payment. This applies to freelance projects, consulting engagements, product orders, and any business-to-business transaction.
Send a receipt when you have received payment and want to give the buyer written confirmation. This is standard in retail, but also good practice for freelancers and service providers. Some clients will request a receipt for their own bookkeeping or expense reporting.
Can One Document Serve as Both?
Not exactly. An invoice becomes a historical record once paid, but it does not replace a receipt. If a client pays immediately (such as in a point-of-sale transaction), you may issue a receipt directly without a preceding invoice. But for any transaction with a payment delay, both documents play a distinct role.
Some invoicing tools mark an invoice as "Paid" after payment is received. This annotated invoice can serve as an informal receipt, but a dedicated receipt is still preferred for formal accounting.
