Questions?

Does billentyű work with NAV?

Yes. billentyű is compatible with NAV Online Számla: every invoice is reported to NAV when issued, and receipts go in the daily receipt data report.

What do I need from NAV?

A technical user in NAV Online Számla. A step-by-step guide with screenshots helps you create it. The demo company does not need one.

Can I take my data with me if I leave?

Yes. You can download every document you issued at any time, and create the tax audit export.

What happens if I stop paying?

NAV reporting, cancelling and correcting the documents you already issued, downloading them and the tax audit export keep working.

Do I need a cash register for receipts?

A webshop can issue receipts this way. If you sell in person, you may need an online cash register; your accountant can tell you.

Is there a minimum contract period?
