What happens after confirmation

The Financial Administration sends us confirmation of your provider selection. We then contact you from ePošťák and prepare your company for receiving e-invoices.

Receiving e-invoices in the web interface remains free within the Free program limits (500 received and 5 sent invoices per month).

You set up the account only after the activation email from ePošťák.

If you came from an integration or invite, we store the continuation and return you after activation.
