If a business gives correct receipts to customers, what purpose does this help serve?

Correct answer: Record keeping and tax compliance

The governing concept is documentary evidence and tax compliance in the legal environment. A correct receipt records the date, seller, buyer or transaction details, goods or services, amount and applicable taxes, as required by the relevant system. It gives the customer proof of purchase and gives the business an auditable record of revenue. Such records help reconcile accounts, calculate and report taxes, handle returns or disputes and demonstrate compliance during inspection. Option A is correct because it captures both record keeping and the tax purpose. Weather improvement, changing a machine's colour and determining a customer's income are not functions of a sales receipt. The exact receipt format can vary, but accuracy and preservation are essential.
