Invoice vs Receipt: What's the Difference?

An invoice and a receipt both record a sale, and they often list the same items and the same total. The difference is timing and purpose: an invoice asks for payment; a receipt proves payment was made. An invoice is sent before the money moves. A receipt is issued after.

Mixing them up causes real problems - a client may pay twice, an accountant may count unpaid income as received, or a customer may not be able to claim an expense. Here is how they differ and when to use each.

What is an invoice?

An invoice is a request for payment. It lists what was supplied, the price, the total amount due, the date it must be paid by and how to pay. Businesses selling to other businesses almost always invoice, because the buyer usually pays later - often 14, 30 or 60 days after receiving the invoice. In tax systems such as VAT and GST, the invoice is also the document the buyer needs to reclaim tax. See what to include on an invoice for the full checklist.

What is a receipt?

A receipt is proof that payment has been made. It shows who paid, how much, when and by what method - cash, card, bank transfer and so on. Shops issue receipts at the till because payment happens at the same time as the sale. Service businesses issue them after an invoice has been paid, if the client asks for one or needs it for their records.

When to use each

Send an invoice when:

• You have finished a job or delivered goods and the client has not yet paid.
• You are billing a business client on payment terms.
• You need to record a sale for tax purposes before the money arrives.
• You bill in stages - a deposit invoice, a progress invoice and a final invoice.

Issue a receipt when:

• A customer pays at the time of purchase.
• A client has paid an invoice and asks for confirmation.
• You receive a deposit or cash payment and both sides need a record.
• A customer needs proof of payment for expenses, reimbursement or a warranty claim.

Can one document be both?

Yes. When payment happens at the same time as the sale - a shop, a market stall, a service paid on the spot - a single document marked "Paid" or "Receipt" can do both jobs. An invoice that has been paid can also be marked "Paid" with the date and method of payment, which some businesses send back as a receipt. What you should not do is send a document titled "Receipt" before you have been paid, or keep sending an "Invoice" for something already settled.

Related documents

• Quote or estimate: comes before an invoice and says what the work will cost. See quote vs estimate vs invoice.
• Pro forma invoice: a preliminary invoice sent before goods are shipped or work starts, often for customs or to request a prepayment. It is not a demand for payment in the same way and is not usually a tax invoice.
• Statement: a summary of all invoices and payments on a client's account over a period.
• Credit note: reduces or cancels an invoice that was issued, for example after a return or an overcharge.

How money moves: quote, invoice, receipt

For most service work the documents follow the same order: a quotation before the work, an invoice when it is done, and a receipt once payment arrives. All three are free to create on this site with the same designs, so your paperwork looks consistent from first price to final payment.

Frequently asked questions

Is an invoice proof of payment?

No. An invoice only shows that payment was requested. Proof of payment is a receipt, a bank statement entry or a payment confirmation.

Do I need to send a receipt after an invoice is paid?

Not always. Many business clients rely on their own bank records. Send one if the client asks, if they paid in cash, or if you want to confirm a large payment clearly.

Which one do I need for my tax return?

Sellers record income from invoices (and, for cash accounting, from receipts of payment). Buyers need invoices - in VAT and GST systems, a valid tax invoice - to claim input tax, and receipts or invoices to support expense claims.
