Frequently Asked Questions
Is Cauri ready for Poland's KSeF e-invoicing mandate?
We keep your invoices structured and compliant, ready for the KSeF mandate. The rollout is phased — large taxpayers from February 1, 2026 and other businesses from April 1, 2026 (timeline subject to change). Please confirm the latest KSeF requirements and your own filing obligations.
What is KSeF and the FA(2) format?
KSeF (Krajowy System e-Faktur) is Poland's national e-invoicing system. Invoices are submitted as a structured XML document (the FA(2) schema) and validated by KSeF, which assigns a unique KSeF ID. This national system is separate from PEPPOL, which we use for cross-border invoicing.
How does NIP validation work?
We run NIP format checks and EU VIES pre-checks on Polish VAT numbers, flagging issues before you send. Please confirm official tax-authority records for 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.
