Why now
Where does logistics lose the most time?
Margins in transport are low and paperwork is heavy. Every order means several documents, several messages and several systems: TMS, telematics, email, accounting software and, since 2026, KSeF.
Freight invoices and subcontractor invoices now arrive in KSeF as structured data. It is a good moment to link them with orders and delivery documents instead of retyping the same numbers in three places.
1 February 2026
All companies receive invoices in KSeF, including invoices from carriers and fuel suppliers. The new JPK_V7 structure with KSeF numbers takes effect.
1 April 2026
The obligation to issue invoices in KSeF covers most businesses, including transport and forwarding companies.
1 January 2027
Transition periods end. KSeF will also cover the smallest carriers who still invoice outside the system.
31 December 2027
announced
Planned end of the period without penalties for KSeF errors. The Ministry of Finance announced the change on 16 September 2026; it still requires an amendment to the act.
