Invoice vs receipt
An invoice asks for money. A receipt confirms money arrived. They sit on opposite sides of the same transaction, and issuing one when the other is required is a common and avoidable error.
The distinction matters because they play different roles in tax records — for you and for your customer.
The core difference
Invoice — a request for payment. Issued when goods are delivered or work is completed, before money changes hands. It creates a receivable for you and a payable for the customer.
Receipt — proof of payment. Issued after money is received. It closes the transaction and is the customer's evidence that they paid.
The sequence is almost always invoice first, receipt second. The exception is immediate-payment retail, where a receipt alone is sufficient because there was never a credit period.
Side by side
| Invoice | Receipt | |
|---|---|---|
| Issued | Before payment | After payment |
| Purpose | Request payment | Confirm payment |
| Creates a debt | Yes | No — it clears one |
| Shows due date | Yes | No |
| Shows payment method | No | Yes |
| Shows balance remaining | Full amount owed | Yes, if part-paid |
| Customer uses it to | Approve and schedule payment | Prove payment, claim expenses |
What each must contain
An invoice needs: the word Invoice, a unique number, issue and due dates, both parties' details, itemised lines, tax shown separately if registered, total due, and payment instructions.
A receipt needs: the word Receipt, a receipt number, the payment date, the payer's name, the amount received, the payment method, what it was for — ideally referencing the invoice number — and any balance still outstanding.
The two fields unique to a receipt are the payment method and the remaining balance. Both matter in disputes about what was actually settled.
Part payments
This is where the distinction becomes practical. A customer pays half of a 500,000 invoice. You issue a receipt for 250,000 that references the invoice and states a 250,000 balance outstanding.
What you do not do is issue a second invoice for the remainder — that duplicates the debt in your records and in theirs. The original invoice stands; receipts record progress against it.
Why sending the wrong one causes problems
- Receipt instead of invoice — you have acknowledged payment you did not receive, and nothing in your records requests it.
- Invoice instead of receipt — the customer has no proof of payment and may be chased for an amount already settled.
- Neither — cash sales with no receipt leave both sides without a record, which is where disputes and unclaimable expenses come from.
Frequently asked questions
What is the difference between an invoice and a receipt?
An invoice requests payment and is issued before money changes hands. A receipt confirms payment was received and is issued afterwards.
Do I need to issue both?
For credit sales, yes — the invoice requests payment, the receipt confirms it. For immediate-payment retail, a receipt alone is enough because no credit period existed.
Can a receipt replace an invoice for tax purposes?
They serve different purposes. The invoice evidences the sale and the tax point; the receipt evidences settlement. Businesses claiming expenses usually need both.
What do I issue for a part payment?
A receipt for the amount received that references the original invoice and states the balance outstanding. Do not raise a second invoice for the remainder — that duplicates the debt.
Which document shows the payment method?
The receipt. Payment method and any remaining balance are the two fields unique to a receipt, and both matter if what was settled is ever disputed.
