In recent years, real-time invoice reporting has become an essential requirement for businesses. This mandate has brought about significant shifts in invoicing and tax practices. It necessitates companies to communicate invoice data in XML format directly to tax authorities without human intervention. Our service is tailored for businesses looking for an efficient method to meet these online invoice data submission obligations.

Our digital VAT and XML consulting service helps with the following: 

  • mapping each field of the ERP/invoicing system to the suitable XML component,
