About the Client
ChainStore Group operates 120 retail stores across the Midwest, serving 2M+ customers annually with a focus on home goods and electronics.
The Challenge
Their legacy POS was slow, crashed during peak hours, and lacked integration with their e-commerce channel. Staff training on the old system took 3 weeks per new hire.
The Solution
We designed and built a modern, touch-first POS interface with real-time inventory sync, customer loyalty integration, and an intuitive UI that cut training time to 2 days.
