What is an invoice?
An invoice is a document issued by a seller to a buyer that formally requests payment for goods or services that have been delivered (or are about to be delivered). It is a request for payment — not confirmation that payment has been received.
Invoices are legal documents that establish a financial obligation. They contain the amount owed, payment due date, and payment instructions. Both parties — the seller and buyer — keep a copy of the invoice for their accounting records.

What is a receipt?
A receipt is a document issued by the seller to confirm that payment has been received. It is proof of a completed financial transaction. Unlike an invoice, a receipt is issued after money changes hands.
Receipts are important for buyers as proof of purchase — for expense claims, warranty purposes, or tax deductions. Sellers use them to acknowledge that a transaction is settled.

Invoice vs receipt for tax purposes
For income tax. Both invoices and receipts help you document your revenue. LHDN may request copies of invoices and receipts during a tax audit. Keep all records for at least 7 years.
For claiming expenses. When claiming business expenses on your tax return, you generally need a receipt (proof of payment) rather than just an invoice. A receipt proves the expense was actually paid, not just requested.
For SST. A tax invoice (a special type of invoice for SST-registered businesses) is required for input tax credit claims under SST. A regular receipt does not suffice for this purpose.
Do you need to issue both?
For most Malaysian SMEs and freelancers, the workflow is: issue an invoice → client pays → issue a receipt. Both documents serve different purposes and you should issue both.
Some businesses use a receipt invoice — a hybrid document that serves as both an invoice and receipt once payment is received. This is common for point-of-sale retail transactions where payment happens immediately.
