More detail
Outages happen on both sides: your shop network or the KRA service itself. Either way, the fix is the same. Each sale is recorded and held, and the system retries submission until it succeeds.
What you should avoid is a setup that blocks the sale until KRA responds. That turns a short outage into a queue of frustrated customers. Offline-first billing keeps the counter moving.

Will I be penalised for an eTIMS outage?
Not for the outage itself, as long as the invoices are filed once the service returns. The risk is from not issuing compliant invoices at all, not from a short delay in transmission.
