Poland’s KSeF e-invoicing system is coming — and the Ministry of Finance wants to make sure no one is left behind.

Starting March 2, 2026, the Polish Ministry of Finance is launching a month-long series of free, industry-specific online training sessions on KSeF (the National e-Invoice System). The concept is straightforward: instead of mixing everyone in one generic webinar, each industry gets its own dedicated day.

22 sectors. 22 days. One goal — e-invoicing readiness.

The schedule covers a remarkably broad range of industries, including retail traders, lawyers, customs agents, automotive businesses, construction, real estate, healthcare, farmers, NGOs, craftsmen, beauty services, restaurants, tourism, and even online sellers. Each sector has a specific date in March, with sessions held daily at 1:00 PM.

What the training covers:

• Key KSeF obligations and exemptions relevant to each industry
• How to access the system and grant permissions to employees
• What tokens and certificates are and how to use them
• Free government tools available for e-invoice management
• A practical step-by-step guide to getting your business ready

Not just online. Local tax offices and regional fiscal chambers across all Polish voivodeships are also organizing in-person or hybrid training events — with schedules varying by region.

Already missed a session? No problem. The ongoing „Wednesdays with KSeF” programme runs until April 29, 2026, covering the basics for anyone just getting started or needing a refresher.

The key takeaway: KSeF is no longer a future concern — it’s a present reality. With over 2 million users already active in the system and mandatory adoption on the horizon, the time to get familiar with e-invoicing is now.
