When Post Audit is applied, the authorities are not involved in the process of exchanging invoices or other data between the trading partners; instead, they can audit the compliance of the process after the exchange.       In a Post Audit model, TrueCommerce retrieves the information, and then we ensure that the information is compliant before we forward it for a qualified signature. Finally, we submit the invoice directly to the recipient, or if a VANs provider is used, TrueCommerce will send the invoice through the VANs partner before sending the invoice to the recipient.
