About the company

The platform also includes a content management system (CMS) for merchants to manage transactions, menus, discounts, and settings. Kody earns revenue through transaction fees charged to merchants for each payment processed. It targets a broad range of customers from SMEs to larger enterprises in retail and hospitality. The company’s goal is to simplify accepting and handling payments while providing operational tools through one integrated platform.
