From certificate to POK
01
Declare a recording unit and collect your certificate
In the tax information mailbox (DIS+), from 1 November 2026 at the earliest. A recording unit is not only premises: the act also counts a website, an application or a vehicle. The certificate is yours; you must collect it yourself, or your accountant can, with your authorisation.
02
Load the certificate into the app
It goes into the phone’s secure storage, and Eetuj uses it from there to sign sales. If you like, you can also save it encrypted to your account (on the web or in the app), or your accountant can upload it there. Another phone or till of yours then downloads it by itself after signing in: within 10 minutes of signing in with no further check, later once you confirm with a six-digit code from an e-mail. You get an e-mail about every download.
03
Tap Record on every sale
Seven fields under § 17 go out and a POK comes back moments later. How long the app waits for the reply is set by the so-called response timeout, for which the act requires at least two seconds. Eetuj waits 15 seconds and only then puts the sale in the queue; there is nothing for you to set.
04
When there is no signal, the sale waits
It goes into a queue and sends itself. The act allows 48 hours from the moment of the sale; Eetuj tries to send it far sooner and makes sure the deadline does not pass.
05
You do not need a certified till
The system is open and no hardware or software certification is required. Any device that can send a signed message will do — and your phone can.
06
A till from 2016 will not be enough
The EET 2.0 interface is incompatible with the old EET: a different namespace, a different schema, a different signing model and different fields. The BKP, PKP and FIK codes do not exist in the new system; the confirmation is the POK. An old till cannot simply be switched over.
