What will the webinar cover?
KSeF is coming — and this is your chance to prepare for it without panic.
From February 2026, large companies in Poland will be required to use the National e-Invoicing System. From April 2026, the obligation will apply to all other businesses.
This is not just another compliance box to tick. It is a completely new way of handling invoices inside the company.
That is why we are inviting you to a joint webinar with experts from ALTO and Altera, who will show you how to move from theory to practice.
What exactly will you gain? A 60-minute action plan
Legal part
(without the jargon)
An ALTO expert will explain what you actually need to know about the regulations, deadlines, and legal obligations.
Practical part
(step by step)
We will show you what the implementation process looks like from an organisational perspective — from analysis and planning to team training.
Technology part
(live demo)
You will see a live demo inside the Altera system showing how easy it can be to send and receive invoices through KSeF, automatically extract invoice data, and manage payments in one place.
No more manual data entry. No more copy-paste finance.
Live Q&A session
Ask our experts anything you want about the legal or technical side of KSeF. We are here to give you real answers, not more confusion.
Who is this webinar for?
This webinar is for you if you are a business owner, finance director, or accountant and you want to:
– prepare your company for KSeF calmly and on time
– avoid costly mistakes and potential penalties
– use this change as an opportunity to automate invoice workflows and save time
Why now?
From 1 February 2026, KSeF will become mandatory for large companies, and two months later for all other businesses.
This is the last good moment to prepare properly and avoid unnecessary chaos.
KSeF implementation is not just about legal compliance. It is also a real opportunity to automate internal processes and make invoice handling faster, cleaner, and less painful.
Why is it worth joining?
✅ You will understand the rules without legal jargon — and see what KSeF actually changes
✅ You will see what implementation looks like in practice — step by step
✅ You will get a clear action plan — from analysis to integration
✅ You will learn how to avoid mistakes and penalties
✅ You will see a live demo of the Altera system — with real examples from day-to-day business operations
✅ You will get access to experts from ALTO and Altera — legal and technology perspectives in one place

CEO & Founder, Altera
