What is an invoice?
An invoice is a commercial document that tells a customer what they are being charged for and how much they need to pay. It often includes an invoice number, customer details, supply/service descriptions, amounts, tax and payment terms.
In the UK, GOV.UK explicitly says an invoice is not the same as a receipt, which is an acknowledgement of payment. VAT-registered business-to-business transactions can also have specific invoice requirements.
What is a receipt?
A receipt is created after the seller or service provider receives payment. It records the amount paid, date, what the payment related to and usually the payment method.
A payment receipt can reference the original invoice so the business can connect the charge and the payment.
Example workflow
- 1Freelancer completes a project milestone.
- 2Freelancer sends invoice
INV-1042for $1,000. - 3Client pays by bank transfer.
- 4Freelancer records the invoice as paid.
- 5Freelancer sends receipt
REC-0884referencingINV-1042and the $1,000 payment.
The invoice and receipt do different jobs, but together they create a cleaner transaction history.
What about “paid invoices”?
Some businesses simply mark an invoice as paid and use that as the customer’s payment record. Others issue a separate receipt. Your product can eventually support both:
Invoice → mark paid → generate receipt
This is a strong long-term product expansion because the same business/customer/item data can be reused.
Receipt vs proof of payment
A receipt is one form of evidence acknowledging payment. A bank statement, canceled check, card statement or payment-processor record can also provide evidence of payment. For some purposes, multiple records may be needed.
Read /guides/proof-of-payment/.
Tax invoices are a separate issue
Do not assume that because a document shows VAT or GST it automatically meets the requirements for a VAT invoice or Australian tax invoice.
- UK: VAT invoices have additional information requirements.
- Australia: tax invoices for GST-registered businesses have specific information rules.
Those should use dedicated product workflows.
FAQ
Should I send an invoice or receipt first?
Usually the invoice comes before payment and the receipt comes after payment.
Can a receipt include an invoice number?
Yes. Referencing the invoice number is useful when the receipt confirms payment against that invoice.
Can I use an invoice as a receipt after it is paid?
Some businesses mark invoices as paid and use them as a payment record. Whether that is suitable depends on the business, customer and local requirements. A separate receipt can make the payment acknowledgement clearer.
Is a receipt the same as a VAT invoice?
No. A receipt acknowledges payment; VAT invoice requirements are a separate matter under UK VAT rules.
