New function in the Online Invoice system

Tax & Legal Alert | PwC Hungary | 13 October 2021

The integration of the Online Cash Register (OPG) and the Online Invoice system has been implemented live since the 1st of October 2021, the National Tax and Customs Administration of Hungary (NAV) announced.  

What does this mean, in detail?

Thanks to this implementation, the Online Invoice system is now able to retrieve data from the simplified invoices generated by the Online Cash Register, i.e. simplified invoices, and cancellation and return receipts are automatically downloaded daily, usually in the early morning hours, into the Online Invoice system.

What does this change mean for companies?

The biggest advantage this innovation brings is that the company's accountants are informed sooner about the purchases (costs) for which the company's employees receive a simplified invoice issued with OPG. This invoice information can be received by the accountants no later than the next morning, and thus the posting of incoming invoices can be efficiently supported if the data of the invoices issued with the OPG are downloaded from the Online Invoice system. Importantly, this feature does not require special development on the company’s side, as simplified invoices are now also available in the Online Invoice 3.0 schema.

It is important to emphasize that in order to reclaim VAT, it will still be necessary to keep the original (paper based) invoice and archive it in accordance with legal regulations.

Due to the fact that all incoming domestic invoices can now be fully downloaded from the Online Invoice system, it is recommended for both companies and accounting service providers to implement a solution that not only downloads data from the Online Invoice system, but also submits it in the appropriate form and import these into the accounting or ERP system, thus reducing the manual work, time, cost and risks related to the accounting of the incoming invoices, as the data in the Online Invoice system is always validated by NAV.

The PwC ByX solution provides the above-mentioned functions, as well as many others that facilitate accounting (e.g. reconciliation of paper-based invoices and NAV XMLs, automated invoice posting, itemized verification of PO data, etc.), even on a fully automated level.
