What is NAV ITAR and is integration mandatory?

NAV is Hungary's tax authority; ITAR is the online cash register system. For e-commerce above the revenue threshold, integration with NAV is mandatory. We implement this per Hungarian tax law.

Do you work with Billingo?

Yes. Billingo is Hungary's popular e-invoicing platform. We integrate it with e-commerce for automatic invoice generation with every order.

Does Hungarian customer data stay in the EU?

Yes. We design all integrations with data storage in European infrastructure — a GDPR requirement as interpreted by NAIH.

02 / 03
Data Synchronisation in Debrecen
We set up data synchronisation between systems for Debrecen companies: ERP, CRM, warehouse systems, websites, and third-party services — without manual work or errors.
03 / 03
Data Synchronisation in Miskolc
We configure data synchronisation between systems for Miskolc companies: ERP, CRM, warehouse systems, websites, and third-party services — without manual work or errors.

Hungarian businesses use a specific stack: SimplePay for payments, Foxpost for delivery, Minimax or Billingo for accounting, Árukereső.hu for price aggregation. Without synchronisation between these systems, data is duplicated, orders are lost and accounting doesn't balance.

We design integrations for the Hungarian market: SimplePay transactions flowing into ERP, Foxpost tracking appearing in the online store, the Árukereső feed updating automatically. All data in the EU per GDPR/NAIH requirements.
