Here are a few important proforma invoice facts.

Is a proforma invoice legally binding?

A proforma invoice isn’t typically considered legally binding since it’s essentially a preliminary bill of sale sent to the buyers in advance of the delivery of goods. A proforma invoice specifies the goods or services the company will provide or deliver, but it’s important to know that it’s more of an estimate or proposal, and it doesn’t really represent a final bill or demand for payment.

A proforma invoice is typically used for importation customs cases or as a prelude before issuing a commercial invoice. The non-binding nature of a proforma invoice means that the terms and conditions, including prices, can still be changed. It’s also often used as a negotiating tool between the buyer and the seller before the final sale is finished.

Proforma invoice vs commercial invoice.

The purpose of a commercial invoice vs a proforma invoice is different.

A proforma invoice is mainly used for providing an estimate or a proposal before the actual transaction takes place. It’s not legally binding since it doesn’t demand payment, and it can also be used for quoting prices, as part of negotiation, or for customs purposes in international trade.

On the other hand, a commercial invoice is used after the sale is completed, as it represents a demand for payment and it details the transaction that took place. This document is legally binding since it’s an official request for payment, and it can also be used as the final bill the seller provides to the buyer.
