If you upload the certificate to the cash registers before 1.1.2027, EET 2.0 will be set up in the cash register so that the cash register automatically activates sending receipts only from 1.1.2027. If you upload the certificate after 1.1.2027, sending of sales will be active immediately. We therefore do not recommend changing the Send receipts to EET setting on the cash register. Keep the default setting, in which the actual fiscalization (sending of receipts) starts automatically from 1.1.2027. If you turn sending on now, unsent receipts will remain in the cash register and the cash register will report an error, because the production servers of the Financial Administration are not running yet.
