Malaysia note
Tax, SST, and MyInvois
For Malaysian users, a simple PDF invoice can help with payment requests and record-keeping, but it is not the same as submitting an e-Invoice through LHDN/MyInvois.
If SST applies to your business, include the SST amount and label it clearly. For SST arithmetic, use the SST Calculator Malaysia or read how to add or remove SST. If you are unsure whether SST or e-Invoice requirements apply, check official guidance or ask a qualified professional.

A simple invoice is a document used to request payment for goods or services. For Malaysian freelancers and small businesses, it usually shows the seller, customer, invoice number, invoice date, line items, payment details, and total amount due.
What should an invoice include?
An invoice should include business details, customer details, invoice number, invoice date, due date if needed, line items, subtotal, tax or SST if applicable, payment details, payment terms, and total. Use clear descriptions so the customer understands what they are paying for.
How do you create a simple invoice?
Start by adding your business and customer details, then add an invoice number, invoice date, line items, quantities, prices, payment details, and payment terms. Check the subtotal, SST or tax if applicable, and final total before sending or downloading the invoice.
Is an invoice the same as a receipt?
No. An invoice requests payment, while a receipt confirms that payment has already been received. For record-keeping, an unpaid invoice should not be treated the same as collected cash.
Can I create an invoice without tax?
Yes, a simple invoice can have no tax if tax does not apply. If you are unsure about SST or other tax treatment, check official guidance or a qualified professional.
What payment terms can I write on an invoice?
A simple payment term can say: Payment due within 7 days by bank transfer. Please include invoice number INV-001 as the payment reference. You can adjust the due date, payment method, and reference wording for your customer.
Can I use the Invoice Generator to create a PDF invoice?
Yes. The Invoice Generator lets you enter invoice details, preview the invoice, and download a simple PDF invoice.
Can Malaysian freelancers use a simple invoice?
Yes. Malaysian freelancers, side-hustle sellers, and service providers can use a simple invoice to request payment and keep basic records. If your business has SST, e-Invoice, or other tax obligations, check official guidance or speak with a qualified professional.
Is a PDF invoice the same as an official Malaysia e-Invoice?
No. A PDF invoice can help with payment requests and simple record-keeping, but it is not the same as submitting an e-Invoice through LHDN/MyInvois. The Invoice Generator does not submit, validate, or connect invoices to MyInvois.
