Country-specific, one platform
What Dynafis connects in this market: Poland
For Poland, KSeF is the primary national rail: Dynafis connects intake, validation, correction, controlled submission, KSeF number, UPO and audit. NBP-based FX logic and Peppol for suitable cross-border cases complement the workflow.
Document → reviewed data
Uploads, inbox and structured e-invoices enter the same recognition, validation and review process.
Accountant & multi-client operations
Client assignment, roles, four-eyes controls, central review queues and status views scale across legal entities.
AI + rules + human review
AI accelerates extraction and classification; deterministic country rules and human approvals constrain risky automation.
Audit trail & DMS
Original, structured data, review decisions, delivery status and evidence stay linked.
European coverage
E-invoicing already usable across many European markets
Dynafis combines one invoice/document platform with Peppol/provider, KSeF and country-specific rails. The exact production route depends on country, use case and account onboarding.
