Proof that
money changed hands.

A receipt confirms payment has been made, where an invoice requests it. It should show who was paid, by whom, how much, when, what for, and the method of payment. For cash jobs it is often the only evidence the transaction happened at all.

What has to be on it?

FieldRequiredWhy
The word 'Receipt'YesSo it is not mistaken for a request for payment. A document that reads like an invoice can be paid twice.
Your business name and addressYesWho received the money.
The customer's nameYesWho paid it. Useful even for small cash jobs, because it links the payment to a job in your records.
A receipt number and dateYesThe date the payment was made, not the date the work happened, if those differ.
What it was forYesReference the invoice number where there is one, and describe the work where there is not.
The amount paidYesAnd whether it settles the invoice in full or in part — a part payment recorded as full is a problem you find months later.
The payment methodYesCash, card, bank transfer. This is what makes reconciliation possible when the bank line does not obviously match.
VAT breakdownRecommendedIf you are VAT registered, show it, and include your VAT number so the customer can reclaim.

Why receipts matter more for cash work

Card and transfer payments leave a trail whether or not you write anything down. Cash does not. A cash job with no receipt and no record exists only in memory, and memory is not evidence.

Unexplained cash deposits that do not match declared turnover are one of the more common triggers for an HMRC enquiry, and the honest answer — poor record keeping — takes far longer to demonstrate than a receipt would have taken to write.

Do you have to issue one?

You must provide a VAT receipt on request if you are VAT registered. Beyond that there is no general obligation to issue a receipt for every transaction, though customers who need it for their own books will ask.

Issue one anyway for cash. It protects both sides, and it is the only practical way to keep cash takings reconcilable.

COMMON QUESTIONS

Questions people ask.

Is an invoice marked 'paid' enough?

Usually, for business customers. A clearly marked paid invoice with the date and method recorded serves the same purpose, provided the customer can produce it.

What about card machine slips?

They evidence the payment but rarely describe what was bought. Keep them, and pair them with your own record of the job.

How long do I keep copies?

The same retention as the rest of your records — at least five years after the 31 January deadline for the relevant tax year for a sole trader, six years from the period end for a company.

Do I have to give a receipt for a cash deposit?

Not legally, unless you are VAT registered and asked for one. Do it anyway. A deposit is the payment most likely to be disputed later — 'I paid you cash in March' — and a receipt stating it is a part payment against a quoted job settles that in a sentence.
