Have you got questions?

We have collected what we think are the most important ones.

Who is NAV XML-based electronic invoicing available to?

NAV’s service is available free of charge to all invoice issuers with a Hungarian tax number. There are both legal and technological requirements for using the service, and you may need[ZS1] InvoiceProxy to meet them.

How long does it take to integrate with an ERP system?

If the invoicing system already has a NAV Online Invoice data link, integration can be completed within a few days as InvoiceProxy is integrated into the existing data feed.

Are NAV XML electronic invoice and NAV Online Invoice the same?

No, they are two different systems. With NAV Online Invoicing, only traditional, digitally signed PDF-based electronic invoices can be issued. However, the data reporting provided by NAV XML electronic invoice and NAV Online Invoice can be considered as the same, as the same XML document is generated to issue the invoice and to report the invoice data.

How is it possible that NAV XML invoices do not require a digital signature?

These invoices do not include a digital signature, nor is it necessary to obtain a separate digital signature for them. This is because the checking of the invoice content and the authenticity and integrity of the content is ensured by NAV using a different technology when the invoices are submitted for mandatory reporting. InvoiceProxy automatically generates and stores for you the so-called hash traces created during the verification process and associated with the invoices. This technology is also free of charge and hassle.
