Should your business in Vietnam build a standalone mobile app or a Zalo Mini App?

In Vietnam, Zalo is the dominant daily communication platform used by over 85% of smartphone users (76+ million people).

What our clients say about us

Read real-world feedback from business owners, retail chains, and marketing directors after launching custom Zalo Mini Apps engineered by Sudo.

During peak lunch and dinner hours, our restaurants used to get overwhelmed. Waitstaff couldn't hand out paper menus fast enough, customers waited too long to add extra items, and handwritten order slips frequently led to missed dishes or wrong table deliveries.Since launching Sudo’s custom Zalo Mini App, every table has its own unique QR code. Guests simply scan the QR code with Zalo to browse our visual menu, customize toppings/ice levels, and submit orders directly to our kitchen and bar screens. When finished, guests pay via VietQR and automatically earn loyalty points tied to their Zalo phone number. Service speed improved dramatically, and we reduced floor staff workload by 30% while boosting guest satisfaction.

In the Ha Long real estate market, property availability and owner pricing change weekly. Previously, our brokerage managed listings across Zalo chat groups and shared Excel files — messages got buried instantly, new agents couldn't tell which plots were already deposited, and sharing land-title photos in group chats risked leaking seller details.Since Sudo built our custom property management Mini App right inside Zalo, our agents filter listings by district, price bracket, area, and legal status in seconds on their phones, and share clean property cards directly with buyers. Sales conversion increased significantly while keeping our proprietary listing database 100% secure.
