BDO TaxConnect:

Online account management interface – automated and legally compliant NAV data reporting

An automated digital solution that makes fulfilling data reporting obligations related to the NAV Online Invoice 3.0 system simple, secure, and error-free. The solution enables real-time uploading of invoice data, receipt of feedback from the NAV, and continuous monitoring of data reporting without the need for special development or manual intervention. 

How does it work?

The online interface connects to the company's own invoicing, ERP, or accounting system and transmits invoice data to the NAV system via a secure, authenticated communication channel.

Main steps of operation:

• After the invoice is issued, the data is automatically forwarded to the NAV
• Data reporting takes place in real time, in a format that complies with legal requirements
• The system immediately receives technical and content feedback sent by the NAV
• The user is notified of any errors via multiple channels (e.g., email, pop-up notification)
• The solution can be easily integrated with both Hungarian and foreign-developed systems

Using it provides the following functional benefits:

• 100% data accuracy: the data on the issued invoice fully matches the data sent to the NAV
• Immediate data reporting to the NAV system
• Immediate confirmation of the success or failure of data reporting
• Retrievability and queryability of submitted invoices
• Accurate, direct upload of export invoice data to the NAV

• Reducing internal administrative burdens
• Ensuring continuous compliance with data reporting requirements

Important information

• The reliability of data reporting is based on the accuracy of the data recorded in the source system
