Estonia e-invoicing for Sap S4hana

Enterprise schema mapping for Sap S4hana teams routing Estonia invoices through a governed API with delivery evidence.

Integrate Sap S4hana without losing auditability.

VATRoute provides a canonical API layer for Sap S4hana invoice flows that need an explicit Estonia routing decision. Validate financial totals, select a maintained ruleset, transmit through an approved adapter, and retain a correlated evidence trail without embedding country logic in the ERP.

What the API controls

• Canonical invoice validation and balancing checks.
• Versioned routing-policy resolution for Estonia (EE).
• Evidence events and signed outbound status callbacks.
