What's new?​

The Czech EET documentation now covers EET 2.0 onboarding, including registering business units in DIS+, obtaining and renewing certificates, installing them in EFR, and configuring the portal unit ID in Loc.LegalId. Guidance also documents supported identifier formats, retry and queue behavior, the configurable Fiscal_timeout minimum of 2,000 ms, required receipt fields, and network prerequisites for *.trzbyeet.gov.cz.

What this means for our users?​

EET 2.0 migration: Czech merchants and integrators can follow the updated guidance to prepare new DIS+ certificates, portal unit IDs, EFR profiles, firewall access, and receipt layouts before onboarding opens on 1 November 2026.

Sales continuity: Integrators can understand how unacknowledged sales are queued and retried, including after the 48-hour deadline, and monitor them through RetryQueued, .trac retry protocols, and journal entries.
