The Client: Zen Cafe Vietnam
Zen Cafe is a modern specialty coffee chain in Da Nang, Vietnam, operating 3 main branches and 2 franchise locations. Led by CEO Trang Ha, the company aims to enhance customer experience, unify its POS infrastructure, and automate accounting workflows to support scalable and data-driven growth.

Customer Review
Applying this new system has really simplified our back-office work. Many of the tasks that our accounting team used to handle manually are now automated, so the team saves a lot of time and avoids unnecessary errors. What I appreciate the most is the real-time visibility. As a CEO, being able to see what’s happening across all stores - sales, inventory, shifts - helps me make decisions faster and with much more confidence. This transformation has made our operations cleaner, more predictable, and much easier to scale.
