Frequently Asked Questions

Everything You Need to Know Overview

What is KSeF and why is every Polish business talking about it?

KSeF is Poland’s government-run invoicing platform. For businesses subject to the mandate, domestic B2B invoices must be issued through KSeF to meet Poland’s e-invoicing requirements.

Once the mandate applies, domestic B2B invoices covered by KSeF must be issued through the platform instead of standard paper or PDF invoices.

No. Once your compliance date passes, paper and PDF invoices are no longer legally recognised for any domestic B2B transaction.

FA(3) is the mandatory XML structure every KSeF invoice must follow. Advintek generates it automatically — your team touches nothing.

KSeF assigns a unique ID to every cleared invoice. Without it, the invoice has no legal standing and VAT can’t be reclaimed.

I heard correction notes are gone how do I fix an invoice error now?

Correction notes were scrapped from February 2026. You now issue a corrective invoice through KSeF referencing the original KSeF ID.

ZAW-FA authorises self-billing inside KSeF. If a buyer issues invoices on your behalf, this form must be submitted first.

From August 2026, every bank transfer linked to a KSeF invoice must include the KSeF reference number in the payment title.

What happens to JPK_VAT reporting now that KSeF is mandatory?

JPK_VAT continues but now references KSeF invoice numbers. Invoices outside the system get flagged with markers — OFF, BFK, or DI.

Yes. Offline mode lets you issue invoices outside KSeF during outages, with submission required the following business day via offline24.

2026 is a grace period with no financial penalties. From January 2027, fines can reach up to 100% of the invoice’s VAT amount.

 

Yes. Polish outbound invoices to EU buyers and non-EU exports both require KSeF clearance before they’re considered valid.

Advintek connects with SAP, Oracle, Microsoft Dynamics, Comarch ERP, and Sage — pulling invoice data through and returning KSeF IDs automatically.

How does KSeF handle attachments like delivery notes or specs?

KSeF doesn’t accept unstructured attachments inside invoices. Additional documents go to recipients separately, and Advintek manages that handoff cleanly.

Advintek tracks every Ministry update and pushes schema and API changes to the platform before your next invoicing cycle runs.

You get a dedicated account manager, structured FA(3) and ZAW-FA onboarding, and support tiers ranging from 8×5 to 24×7.
