Why real-time invoice data disclosure is inevitable

Since 2018, real-time reporting has been an obligation associated with issuing invoices

From the beginning of 2021, almost all invoices subject to Hungarian regulations have to be reported to NAV

NAV may oblige electronic invoice data retrieval and transfer in a predefined data structure for tax control purposes


Efficient and customised data disclosure without replacing existing software

Our off-the-shelf solution, VATOnline, can be flexibly connected to any invoicing system, after which the data disclosure requirement is fulfilled on an ongoing basis.

VATOnline is integrated between the invoicing software and the tax authority system, meaning that there is no need to replace or upgrade the existing system.

VATOnline is a solution that can be used to fulfil the obligation to export data and generate a file with the appropriate data structure for the tax administration's audit at any time.


Data disclosure in accordance with legal requirements

Continuous communication with the ERP system

Monitoring, logging and troubleshooting capabilities

Immediate notification in case of defective data disclosure
