Frequently asked questions

When does e-invoicing become mandatory in Slovakia?

The announced start of the B2B mandate is 1 January 2027, using a Peppol-based 5-corner model with reporting to the Financial Administration.

Can Slovak companies use Peppol before the mandate?

Yes — the network is live in Slovakia today. Connecting early means invoices to Belgian, German or Romanian customers already flow compliantly and 2027 becomes a non-event.

What does a connection cost?

Receiving is free forever with Verteco; sending starts at €2/month on the Slovak price book with a public lowest-price guarantee.
