Poland's National e-Invoice System (KSeF) becomes mandatory for all B2B invoices on July 1, 2026. Inratio gives your foreign-owned Polish entity full KSeF compliance plus an English-language workflow layer.
Incoming KSeF invoices are categorized by cost type, project, responsibility center — based on history. Manual categorization only for new patterns.
Multi-level approval matrix — by amount, by category, by manager. You set thresholds once, Inratio routes invoices automatically. Audit trail for every decision.
Every invoice action (received, categorized, approved, paid) is timestamped and attributed. Ready for Polish tax authority audits.
Unusual amounts, suspicious vendors, duplicate invoices — Inratio flags before approval. Catch fraud and errors before payment.
KSeF (Krajowy System e-Faktur) is Poland's National e-Invoice System. From July 1, 2026, all B2B invoices in Poland MUST be issued through KSeF. There are no exceptions for foreign-owned companies — if you operate a Polish entity, you must comply.
Yes. KSeF applies to invoicing within Poland, regardless of where the parent company is located. Your Polish entity (Sp. z o.o., S.A., branch office) must issue and receive B2B invoices through KSeF from July 1, 2026.
Inratio connects directly to KSeF for you. You don't need to log into KSeF separately — invoices flow into Inratio automatically, get auto-categorized, routed for approval, and synced back. We can run your accounting or adapt to your existing one — either way, Inratio handles the document workflow layer.
B2B invoices to non-EU and non-Polish customers may have different rules. Inratio handles both KSeF (domestic Polish) and traditional invoicing for international clients in one workflow.
KSeF itself is Polish-only. Inratio adds an English layer on top — invoice categorization, approval workflows, and reports are available in English. The underlying KSeF document remains compliant Polish.
