KSeF – What is it and how does it work? Everything you need to know about e-invoices in the PasCom system

 

From 2026, every entrepreneur will be required to issue invoices through the National e-Invoice System (KSeF). The change introduced by the Ministry of Finance aims to simplify settlements, increase transaction transparency, and reduce tax abuses. At the same time, it requires technical adaptation of financial-accounting systems (and more) to the new operating model.

TSL sector companies (transport, forwarding, logistics), where hundreds of invoices related to shipments, fuel purchases, or operating costs are issued daily, need efficient and automated solutions. That’s why the KSeF Automation Module in PasCom was created – a tool enabling a secure transition to e-invoicing without the need for external platforms.

What is the National e-Invoice System

KSeF is the Ministry of Finance’s central system for issuing, receiving, and archiving structured invoices. Each document must be sent to KSeF in XML format, compliant with a strictly defined logical structure. The invoice gains legal force only after proper acceptance by the system. This means that simply sending a PDF invoice via email will no longer suffice. The new solution centralizes document circulation and sends data directly to the tax authorities. It reduces fraud risk, speeds up controls, and facilitates invoice archiving for companies. For TSL sector enterprises, this means the need to adapt systems to the new settlement model.

KSeF Mandatory Implementation Dates

  • February 1, 2026 – mandatory for companies with turnover above PLN 200 million in 2024
  • April 1, 2026 – mandatory for remaining VAT taxpayers
  • January 1, 2027 – mandatory for smallest entrepreneurs (up to PLN 10,000 monthly)

Transport and logistics companies should now analyze their 2024 revenues. If they exceed the required threshold, it’s worth starting e-invoice implementation in the PasCom system as soon as possible to smoothly transition to the new settlement model.

e-Invoice Handling in PasCom System – TSL Solutions

PasCom is a system supporting operational and financial processes of transport, fleet, and forwarding companies. It enables comprehensive cost recording, order control, vehicle management, and settlement documentation. The latest version includes a KSeF-compliant module enabling automatic and secure e-invoice handling according to Ministry of Finance requirements.

Two Ways to Handle e-Invoices in PasCom

Users can choose the option suited to their company’s needs:

  • XML invoice export – after document approval, it can be saved locally and sent to the Ministry’s system manually
  • KSeF Automation Module – after document approval, it is automatically sent to KSeF. The module also handles UPO confirmations and KSeF number registration

For companies generating a large number of invoices, daily automation brings real time savings and reduces errors related to manual XML file handling.

How to Implement KSeF Integration in PasCom

The process involves four steps:

  • Step 1 – extend license with KSeF Automation Module
  • Step 2 – generate authentication token or certificate in KSeF system
  • Step 3 – enter configuration data in PasCom
  • Step 4 – install integration service and set its work schedule

The system enables real-time tracking of document statuses, KSeF numbers, and error analysis. Users can quickly correct e.g. missing NIP or incorrect customer address and resend the corrected document to KSeF.

KSeF and Process Compliance in TSL Companies

In transport, forwarding, and logistics companies, the invoice is part of a broader business process. E-invoicing requires consistent data and precise mapping of cost and revenue documents in the e-invoice structure. The PasCom KSeF module helps maintain consistency between operational and accounting data, increasing settlement transparency and efficiency.
