E-invoicing mandate — Slovenia
The format is prescribed, the route is not: the invoice must be structured, but which channel carries it to the recipient is left to the parties. A format tool is sufficient here as well.

From 2028 Slovenia requires e-invoices exclusively between businesses — with no option in favour of paper, but also without central clearance: the exchange runs decentrally through approved providers. ⚠ Anyone reading "Slovenia from 2027" is confusing a partial deadline with the main one: April 2027 concerns only the accreditation of the providers, not the businesses. For micro-businesses the tax administration provides a free route.

Create and validate: Peppol
Stated limit: Invoiceflair creates, validates and reads formats. It is not a Peppol access point and not a clearing service — it does not perform transmission to an authority's platform.
