A commercial invoice is typically used for exporting goods internationally. This commercial invoice template includes spaces for the names of the individuals or businesses involved in the transaction, the items being shipped, where the items were manufactured, and Harmonized System (HS) codes for the items. This is essentially a customs declaration stating the value of the goods being shipped.
A pro forma invoice describes the value of a transaction prior to its completion. The term pro forma refers to a planned business transaction. Pro forma invoices are commonly used when two companies are just starting to do business together and for international trade. The invoice describes the terms of a deal and can sometimes be used to expedite the customs and shipping processes.
One option for receipts is to simply mark your billing or sales invoice as paid and send a copy to the customer. But if you need a detailed receipt for your business, this template allows you to track payment methods for your records while providing clients with their own receipt.
You may still be mailing paper invoices or you may be doing all your billing and payments over the internet, either using a website that accepts charge cards or an online payment system that uses email like PayPal. As a freelancer, this affects the part of your invoice that lists how you want to get paid. You may even offer your client a variety of payment options, and all of those should be mentioned on your invoice.
