When the taxpayer has created his electronic invoice, the taxpayer sends the invoice in XML format to the Ministry of Finance for validation. The tax administration has three hours after receiving the invoice to validate it and to send a confirmation message, which the recipient then receives including the invoice. This process takes place at the structural level and also includes semantic validations (amounts, addresses, etc.).
The invoice recipient must then, upon receipt of the invoice, send a confirmation message to the Treasury. This message contains the rejection or acceptance of the invoice.
