A sales invoice in NetSuite is a document generated within the system confirming the sale of goods or services by a company to a customer. The solution allows for the generation of a printout that meets the required legal standards.The system also supports the printing of corrective invoices, which are used to amend errors made in the original invoice. A prepayment invoice, issued before the final service is provided or goods are delivered, serves as confirmation of the received advance payment and forms the basis for VAT settlement.The prepayment invoice printout includes details on the paid advances, their dates, and the applicable VAT settlement.
A final (settlement) invoice, issued after the service is performed or goods delivered, includes all paid advances (which may be multiple) and provides the VAT settlement.Both sales invoices, prepayment invoices, and final invoices are subject to correction using a corrective invoice.



The legal basis for the solution is regulated by the Value Added Tax (VAT) Act. In particular:
The rules for a sales invoice are defined in Article 106e.
The rules for a corrective invoice are defined in Article 106j, paragraph 2.
The rules for a prepayment invoice are defined in Article 106f.
