Invoice vs Receipt: Differences & Payment Examples

An invoice sets out a sale or charge and what is payable. A receipt acknowledges money received. The distinction is purpose, rather than a strict before-and-after rule: an invoice can be issued for advance payment, paid immediately, or retained as a paid invoice after settlement.

If you need to ask the customer to pay, prepare an invoice. If you need to confirm a payment, prepare a receipt or a paid invoice that accurately identifies that payment. Neither document alone proves every aspect of delivery or tax compliance.

Invoice and receipt compared

Detail	Invoice	Receipt
Main question answered	What is being charged and what remains payable?	What payment was received?
Amounts	Charges, tax, total and any balance due	Amount received and, if useful, remaining balance
Dates	Issue date, supply period and applicable due date	Payment date and receipt issue date if different
Payment information	Instructions and reference for payment	Method and transaction reference for the payment received
Link to other records	Quote, order or contract reference	Invoice or order the payment relates to
Evidence	Details of the billed transaction	Seller’s acknowledgement of a payment

Accounting treatment depends on your accounting method and tax rules. Do not treat a new receipt as an additional sale if it simply confirms payment of an existing invoice.

When to issue an invoice

Use an invoice for a customer buying on credit, an agreed project milestone or another billable event under your agreement. It should identify the seller, buyer, charges and currency, with tax particulars where applicable. Add a due date and payment reference so it can move through the customer’s approval system.

An invoice can also request a deposit before work begins. Check the applicable tax timing for advance payments rather than assuming that no tax obligations exist until delivery. Our invoice creation guide covers the practical fields and checks.

When to issue a receipt

A receipt is useful for a cash sale, an immediate card payment, an advance or a payment against a previous invoice. Issue it for the amount actually received. If a customer sends a screenshot of a pending transfer, check your own payment records before acknowledging receipt.

Customers may use receipts for internal expense claims or returns, but acceptance depends on the recipient’s requirements. A general payment receipt does not automatically qualify as a tax invoice for recovering VAT or GST. Ask which evidence the customer needs.

Worked example: two payments against one invoice

This fictional transaction uses USD and assumes no tax or discounts. An invoice for $1,200 is issued on 4 October. The customer pays $400 on 6 October and $800 on 19 October.

Record	Amount recorded	Balance after payment
INV-0042: project invoice	$1,200 billed	$1,200
RCT-0018: bank transfer on 6 October, applied to INV-0042	$400 received	$800
RCT-0019: bank transfer on 19 October, applied to INV-0042	$800 received	$0

The first receipt should say “Part payment against INV-0042,” not “Invoice paid in full.” The second may confirm that the invoice is settled. The two receipts together acknowledge $1,200, matching the original invoice.

If you maintain a sales ledger, link both payments to the same invoice. Recording an invoice and two receipts as three separate sales would overstate the transaction.

What to include on a payment receipt

Use these practical fields, then check any local mandatory particulars:

1. Receipt identifier and seller details.
2. Customer or payer name where needed.
3. Amount actually received, with currency.
4. Payment date, method and reference.
5. Invoice or order reference and a short description.
6. Whether the payment is a deposit, part payment or final settlement.

Do not include full payment-card numbers or unnecessary bank details. Keep the record specific enough to reconcile without exposing sensitive information.

Can a paid invoice replace a separate receipt?

For an ordinary confirmation, a paid invoice may be sufficient if it shows the payment and zero balance, and the customer accepts it. Where a separate receipt is required, issue one that references the invoice. Keep the billed amount and amount received distinct in both records.

In this app, add the actual payment under Payments on the invoice. Mark as fully paid records the outstanding balance; use it only after confirming receipt. The paid stamp reflects your entries, not verification by a bank or payment processor.

To prepare a separate document, use the receipt generator and check its items, payment record and references. Changing document type resets payment records, so conversion itself does not carry proof of payment into the new document.

Refunds, missing receipts and record keeping

If you refund money, retain the original payment receipt and record the refund with its date and reference. Where the billed amount is reduced, a credit note may also be appropriate. A credit note adjusts a charge; it does not by itself prove a refund reached the customer.

For a lost receipt, provide a copy of the existing record with the original receipt identifier instead of recording a second payment. Keep invoices, receipts and supporting payment evidence together. Export your documents and browser backup; clearing local browser storage can remove the app’s saved records.

Official guidance and scope

GOV.UK distinguishes an invoice from an acknowledgement of payment. HMRC’s VAT record-keeping guidance explains VAT invoice and supporting-record requirements in the UK. Other countries and customer expense policies may require different evidence; this guide explains the document workflow rather than deciding tax deductibility.
