Emergency Mode vs offline24 in KSeF — Which One Saves You When

You switch on offline24 yourself, whenever you want — no internet, KSeF running slow, or simply by choice. You must submit the invoice to KSeF by the next business day at the latest. Emergency mode kicks in only when the Ministry of Finance officially announces a KSeF outage in the Public Information Bulletin (BIP) and interface software. Then you get 7 business days from the end of the outage. Both modes require a KSeF type 2 certificate and two QR codes on the invoice. What sets them apart is mainly who triggers them and how long you have to submit.

KSeF emergency mode vs offline24 — the difference and when each saves you

offline24 and emergency mode look almost identical on the invoice itself — an invoice issued outside the system, the FA(3) structure, two QR codes — but one thing separates them: whose problem it is. You use offline24 when your own internet or software fails, and you get until the next business day to send it to KSeF. Emergency mode only kicks in once the Ministry of Finance officially declares a KSeF outage — and then you get a full 7 business days from when it ends. Below I explain how not to confuse the two, and what to do when one turns into the other.
