Automated Invoice Management

With over 20 years of experience, Infinite helps companies move away from paper-based invoicing through secure and fully automated e-invoicing integration.

More than 100 businesses in Hungary already use our system to eliminate paper from their outgoing invoice processes. Even invoices sent to partners who still prefer paper can be managed electronically in-house—no paper required unless you choose to use it!

While accepting e-invoices isn't mandatory yet, since July 2025, energy providers like MVM and E.ON have been sending electronic invoices only to their business customers.

The era of avoiding e-invoicing is over.

Mandatory E-Invoicing in Hungary

Since July 1, 2021, real-time invoice reporting to the NAV Online Invoice System has been mandatory for all VAT-registered businesses in Hungary. Every invoice — including B2B, B2C, and cross-border — must be submitted in NAV 3.2 XML format via the official API. Companies are expected to implement automated, secure integrations to meet technical and legal requirements. Manual processes and non-digital formats are no longer accepted, and non-compliance may lead to penalties or audit exposure. Infinite provides a fully compliant and seamless solution to simplify your NAV. reporting obligations.
