Frequently Asked Questions

No — this generates an ESTIMATE for the buyer to review before a sale is finalized. It's explicitly not a tax invoice and shouldn't be used for GST filing or as a formal demand for payment.

It tells the buyer how long the quoted price and terms remain valid — after that window, you'd typically issue a new proforma or the actual tax invoice.

Before a sale is confirmed — e.g. giving a prospective buyer or importer a cost estimate for approval, internal budgeting, or securing a letter of credit.

It's a solid starting draft, but have your accountant confirm the specific terms and disclaimers your business typically includes on proformas before relying on it.
