KSeF: rules for issuing invoices at ELETOR

(effective from 1 March 2026)

Dear Customers,

We would like to inform you that, in connection with the introduction of the mandatory National e-Invoicing System (KSeF), we are beginning an organisational transition period for the new invoicing rules from 1 March 2026.

🔹 From 1 March 2026, invoices will be issued in the KSeF system,

🔹 You will also receive a visual version of each invoice as a PDF or paper printout.

From 1 April 2026, all invoices issued by ELETOR Sp. z o.o. will be issued exclusively in structured form in KSeF, in accordance with the applicable regulations.

What does this mean in practice?

✔ The official invoice will be issued in the KSeF system and assigned an individual identification number.

✔ You will receive a readable version (PDF or printout), reflecting the data in the KSeF system.

✔ This document may be used as proof of purchase when exercising your rights under the statutory warranty for defects and the commercial guarantee.

The changes are intended to ensure full compliance with the regulations and to organise document circulation.

If you have any questions, we remain at your disposal.

The Management Board of ELETOR Sp. z o.o.
