In order to create invoices that can be turned into XML files, VAT Expert can be used as a connecting bridge between the invoice and the VAT determinations that VAT Engine will produce. This is a manual process where every invoice will be created one at a time following these steps:
- A customer completes an invoice in VAT Expert, providing the transaction’s required information that VAT Engine needs.
- This information is sent to VAT Engine via VAT Expert.
- VAT Engine will transform these parameters into an official invoice that includes the customer’s and supplier’s fiscal obligations for a transaction.
- Every time a new needed fact is added to VAT Engine, it will also be available in the next version of VAT Expert.
