FakturaFlow is a Poland-focused SaaS for accounting firms (biura rachunkowe) and B2B businesses that need to comply with KSeF, Poland's mandatory national e-invoicing system rolling out in 2026.

FakturaFlow provides: - FA(3) structured invoice generator compatible with the current Ministry of Finance specification - XML validator that catches structural errors before submission to KSeF - Encrypted multi-tenant storage of client KSeF tokens - Linked correction invoices tied to original documents - Export packets ready to import into other accounting systems - Multi-client (biuro rachunkowe) mode for firms managing multiple taxpayers - Polish and English UI Two public free tools available to anyone, not just paying users: - KSeF XML Validator: fakturaflow.pl/walidator - PDF to XML Converter: fakturaflow.pl/konwerter-pdf-xml FakturaFlow is hosted in Poland with EU data residency. All KSeF integrations use the official Ministry of Finance API. JPK schema compliance is maintained continuously. Pricing starts with a single-firm plan; higher tiers add unlimited clients and priority support. Free trial available without credit card. Ideal for: Polish accounting firms (biura rachunkowe), Polish B2B companies invoicing other businesses, Polish branches of international companies preparing for KSeF mandate.
