// Apartment and Complex Management

KATSİS

A residential management platform that brings managers, residents and staff together in one system.

We built KATSİS to bring apartment and residential complex management into a single panel: dues and debt tracking, cash management, announcements, support tickets, virtual POS and SMS modules — with a web panel plus iOS / Android and Windows apps.

// Restaurant Management

RestaurantBill

A restaurant management system that keeps waiters, kitchen and cashier in sync in real time.

We built RestaurantBill, an order and kitchen display system for multi-branch restaurants: waiter, kitchen and cashier screens share orders in real time, while branches, staff, menus, cash and financial reports are managed from a single panel.
