About proforma invoice _ A Proforma invoice is an invoice provided by a supplier in advance of providing the goods or service. A quotation in the form of an invoice prepared by the seller that details items which would appear on a commercial invoice if an order results. It is more of a customs declaration form used in international trade that describes the parties involved in the shipping transaction, the goods being transported, and the value of the goods. It is the primary document to declare value for customs. It is not a true invoice, because the seller does not record a pro forma invoice as an accounts receivable and the buyer does not record a pro forma invoice as an accounts payable.
Their Details and Yours _ must be complete This is basic stuff, but you can't afford to forget it. In addition to the client's address, make sure to include the name of the client's contact person who handles your account! A company with three employees can figure out what you're doing; but in big companies, invoices get misplaced, especially if there's confusion over who belongs to which project. You'll also need your company name, your name, address, telephone number and email address. If they have any questions about the charges, contacting you should be as easy as possible.
