Frequently Asked Questions
Is e-invoicing mandatory in Slovakia right now?
For B2G (invoicing public bodies), yes — e-invoicing via the IS EFA platform has been required in phases since 2023, with EN 16931 / PEPPOL accepted. For B2B, Slovakia has approved a mandate for e-invoicing and e-reporting expected from January 1, 2027, using a PEPPOL-based model, with a voluntary transition from 2026 (timeline subject to change). Please confirm the latest requirements and your own obligations.
What network and format will Slovakia use for B2B?
Slovakia is preparing a decentralised, PEPPOL-based model for mandatory B2B e-invoicing with near real-time reporting to the Financial Administration. Cauri generates EN 16931-compliant PEPPOL BIS 3.0 invoices and connects via a certified PEPPOL Access Point, keeping you ready as the national system finalises. Please confirm the latest rules.
How does IČ DPH (VAT number) validation work?
We run IČ DPH format checks (SK followed by ten digits) and EU VIES pre-checks to flag issues before you send. Please confirm official Slovak Financial Administration records for final accuracy.
Can I invoice clients in other EU countries?
Yes! Through PEPPOL, you can send e-invoices to 32 European countries, including all EU members. Cross-border compliance is handled automatically.
