Problem
Small and medium-sized businesses in Croatia face fragmented workflows when issuing invoices, handling fiscalization, processing payments, and managing e-commerce sales. Manually re-entering data across separate systems wastes time, increases error risk, and complicates compliance with evolving e-invoice and fiscalization regulations.
Solution
BillKO provides a unified cloud platform that connects invoicing, fiscalization, e-invoicing, POS payments, and online sales automation in a single system. Businesses can issue B2C, B2B, and B2G invoices manually, automatically, or via POS terminals and Android devices, with the platform automatically applying the correct fiscalization rules and sending e-invoices based on customer and invoice type. The system integrates with payment gateways and e-commerce platforms, so online orders or successful payments automatically generate and deliver invoices without manual copying. BillKO also offers a certified access point for sending and receiving e-invoices, along with smart reporting dashboards that track sales, collection status, payment methods, and period comparisons. The platform is designed for users across various industries, including craftsmen, companies, associations, rental providers, and accounting services.
