Slovakia e-Invoice
EN 16931 / Peppol BIS 3.0 e-invoicing for Odoo — with Financial Administration DRR e-reporting, BYOK Access Point
First-mover pack for Slovakia's structured e-invoicing mandate: voluntary from May 2026, mandatory from 1 January 2027. Slovakia adopts the EU 5-corner Peppol model — the supplier issues an EN 16931 UBL 2.1 invoice, sends it through a Peppol Access Point, and reports the same data to the Financial Administration (Finančná správa) over the DRR interface.
EN 16931 / Peppol BIS 3.0 UBL
Customer invoices and credit notes are converted to compliant UBL 2.1 XML with the Slovak VAT scheme, EAS-9944 Peppol endpoints and euro currency, built on a shared, well-tested UBL engine.
DRR e-reporting
The same dataset feeds a canonical Financial Administration DRR report (per-rate VAT breakdown and totals), submitted over your own reporting token — the domestic continuous-transaction-control leg.
Peppol Access Point (BYOK)
Validate, send, status-poll and look up participants over the Peppol Access Point you already contract with. Sandbox and production endpoints are editable; requests retry with backoff and every call is logged. No vendor account is bundled — bring your own key.
Real IČ DPH & IČO validation
The Slovak VAT number (IČ DPH) is checked with the published modulo-11 rule and the company registration number (IČO) with its weighted modulo-11 check digit — on both company and partner records.
