Invoice example With GST & PST An invoice not only shows the customer or client how much money is due but provides tax information, in some countries multiple taxes may apply, for example in Canada it is required to put the Supplier's identification numbers for GST and QST taxes purposes. Whenever a taxable sale is made, the customer must be informed that GST and QST are added to the selling price. As there are no standard invoices required by law for this purpose, you must indicate the amount of the taxes on the cash register receipt; on the invoice or contract remitted to the customer. If you choose to indicate the GST and the QST, the amounts must be stated clearly.The European Union requires a VAT (value added tax) identification number on invoices between entities registered for VAT.
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.
