The regulations of IAPR stimulate that the values of invoices must be transmitted in euro. In cases where the currency is not in euro, it is suggested to include the AC fields (alternative currency) in the JSON file document. The implementation should be developed in the customer's systems to avoid the risk of significant discrepancies during the transformation from foreign currency to euros. By following this procedure, the amounts of the documents transmitted to IAPR correspond to those in the customer's systems.
