Business ecosystem, integrated with AI technologies
Polish SMBs, accounting firms and agencies need one coherent platform — not a patchwork of single-purpose tools that don't talk to each other. Every extra login, every separate license and every manual integration is hours lost to operations that shouldn't be here.
Our ecosystem unifies KSeF e-invoicing, online accounting, B2B and B2C CRM, ERP, HR, project management with time tracking, online appointment booking, SMS and WhatsApp notifications and full marketing automation in one platform with built-in AI. One login, one contract, one invoice in PLN.
Built-in NIP, REGON and KRS lookup against the GUS registry, counterparty verification against the VAT white list, EU VAT validation via VIES, one-click JPK_FA exports and full alignment with the Ministry of Finance FA(2) schema — ready for mandatory KSeF e-invoicing before it goes live.
EU data centers, encryption at-rest and in-transit, GDPR-grade data protection aligned with Polish data-protection law, Polish-language support via chat, email and phone, contracts in Polish and transparent PLN pricing — all in one subscription you can reconcile like any other KSeF invoice.
