Katalin Kauzli gave a presentation on building an invoice management service for banks to help small and medium enterprises. Currently, the payments ecosystem is digital but the invoicing process remains largely paper-based. Charlie-India helps banks provide a seamless digital invoicing experience by storing invoices, allowing businesses to issue and receive digital invoices, and integrating invoice data with bank transaction data and accounting systems. A case study from Hungary demonstrated an integrated invoicing and payments ecosystem where invoice and payment data are automatically matched at the bank. The presentation concluded with a demonstration of a real-life invoicing ecosystem simulation to experience the benefits of working with digitally accessible invoice data.
