Why does building a traditional Mobile App leave businesses out of breath?
Costs of hundreds of millions, expensive app-install ads and customers who won't download apps are the biggest barriers. That is why Zalo Mini App has become a breakthrough solution for business growth.
Challenges
Traditional Mobile App development is too expensive
App-install ads are too expensive and customers won't download
Customers won't fill in sign-up forms, 75% abandonment rate
SMS Brandname is too expensive and lacks engagement
Solutions
Save up to 70% of investment costs, launch in just 2-3 weeks
Unlike traditional Mobile Apps that require two separate development teams for iOS (Swift) and Android (Kotlin), Zalo Mini App runs on modern web technology (ZaUI, React, Vite) embedded directly in the Zalo app. This saves businesses 60% to 70% of the initial investment budget.
Delivery time is cut from 4-6 months to just 14 to 21 working days. There is no bulky server infrastructure to maintain and no complex App Store/Google Play review to wait for, so businesses can seize opportunities right away.
No download needed, opens instantly in Zalo (tap and use right away)
Zalo is Vietnam's national messaging app with more than 76 million regular active users. With a Zalo Mini App, your business appears right on your customers' phones without having to convince them to download another heavy app.
Customers simply scan a QR code on the table, at the counter or on product packaging, or tap a link in Zalo chat / social media, and the app opens in under 1 second. Removing the installation barrier increases reach to new customers 4 to 5 times compared with a regular app.
1-Click Login with automatic Zalo phone number capture
One of the reasons 75% of customers give up is a cumbersome sign-up process. With Zalo Mini App, Sudo integrates 1-Click Login: when customers open the app, Zalo automatically shows a popup asking for permission to share their phone number and profile.
With a single tap, the system captures the verified phone number from Zalo and creates a member account instantly. Businesses collect high-quality customer data (Clean Data) without interrupting the shopping experience.
ZNS messages 50-70% cheaper than SMS, with over 90% open rate
Instead of paying millions for short, dry SMS Brandname messages, Zalo Mini App integrates ZNS (Zalo Notification Service), sending messages straight to the customer's Zalo inbox. ZNS messages display the verified brand logo, rich content with images and call-to-action (CTA) buttons.
The system automatically sends notifications when customers earn points, receive birthday vouchers, have an order confirmed or need an appointment reminder. Each ZNS message costs only 30% - 50% of an SMS Brandname, while the open and read rate exceeds 90%.
