Peppol e-invoicing

Electronic invoices over the Peppol network — we are preparing for mandatory e-invoicing.

What it is

We can create invoices in the European UBL format (Peppol BIS 3.0). Between organisations that both use TR3X One, invoices arrive directly as received documents. Sending over the Peppol network, with our own access point, launches at the end of 2026; until then, and whenever delivery over Peppol fails, the invoice goes out by e-mail as a PDF (in Czechia with ISDOC as well).

What it does for you

  • You will be ready for mandatory e-invoicing in Slovakia from 2027 without changing systems.
  • An invoice never gets lost — when one channel fails, another is used.
  • The customer loads the invoice into their system without retyping.
