Can a receipt be used to claim a tax deduction?

Often yes — a receipt proves you paid for something, which is the evidence tax authorities want for a business expense. For larger or VAT-reclaim purchases, you may also need a proper tax invoice. Keep both where you have them.

Is a paid invoice the same as a receipt?

An invoice marked 'paid' can serve a similar purpose, but a receipt is the cleaner record of payment. The safest practice is to issue a separate receipt or payment confirmation once an invoice is settled.

Do I need to send a receipt after every invoice?

It's good practice but not always legally required. Many businesses simply confirm payment by email. If a client specifically asks for a receipt for their records or expenses, you should provide one.

Invoice vs Receipt: What's the Difference?

What an invoice is for

An invoice is a formal request for payment. It sets out what was supplied, how much is owed, and by when. Because it's issued before money changes hands, it acts as the legal basis of the debt the client owes you. Invoices are central to credit terms, where you supply first and get paid later.

What a receipt is for

A receipt is proof that a payment has been made. It's issued after the customer has paid and records the amount, the date and the method of payment. Customers use receipts for their own bookkeeping and for tax or expense claims, while you keep one as evidence the debt was cleared.

When to use each

Use an invoice whenever you're billing for work or goods that will be paid later — the typical freelance or B2B arrangement. Use a receipt to confirm payment, especially where the customer needs evidence for their records. A retail card payment may produce only a receipt; a 30-day supplier arrangement produces both.

Put simply: an invoice is issued before payment and requests the money owed, while a receipt is issued after payment and confirms the money was received. The invoice establishes the debt and the due date; the receipt proves the debt was settled.
