A proforma invoice, often abbreviated as PFI, is a preliminary invoice sent to a customer before the goods or services have been delivered. It's a way for businesses to provide a detailed quote or estimate of the expected charges, helping customers understand the costs upfront. Proforma invoices are not legally binding and do not have a unique invoice number, making them ideal for planning purposes.
