Custom Ecommerce Platform for Healthcare
See how InApps rebuilt Trung Son's pharmacy ecommerce as one connected web, mobile and admin platform, with real-time ERP sync.
Custom Pharmacy E-Commerce Platform
Trung Son Pharmacy operates a nationwide pharmacy retail chain in Vietnam and needed to modernize its ecommerce stack, spanning web, mobile, and admin, while migrating years of store and inventory data from its legacy system without disrupting daily store operations.
InApps designed and built a full mobile-first ecommerce platform - customer mobile app, web app, and web admin console, with real-time ERP synchronization keeping every store's inventory and pricing accurate.
Project goals
- Design and build a full ecommerce stack: web app, mobile app, web admin
- Migrate legacy store and inventory data into the new platform
- Synchronize ecommerce data with Trung Son's ERP system in real time
- Maintain on-time delivery operations across all stores during the transition
- Operate as a dedicated ODC team for ongoing platform evolution
Client requirements
Across each key area, these requirements shaped every architectural and product decision we made.
Multi-Channel Ecommerce
Trung Son needed customers to browse and buy seamlessly whether they were on the website, the app, or being helped by in-store staff — with every channel reflecting the same stock and price.
- Customer-facing web app
- Native mobile app for everyday shopping
- Web admin console for store and catalog management
- Consistent pricing and inventory across all channels
Data Migration
Years of product, pricing, and customer history lived in a legacy system that couldn't simply be switched off, the migration had to be safe, validated, and reversible if anything went wrong.
- Full migration of legacy product, pricing, and customer data
- Zero data loss during the cutover
- Validation process to confirm migrated data accuracy
- Rollback plan in case of migration issues
Real-Time ERP Synchronization
With dozens of physical stores selling the same inventory, even a few minutes of stale data could mean overselling a product that was already out of stock.
- Real-time sync between the ecommerce platform and Trung Son's ERP
- Consistent stock and pricing data across all physical stores
- On-time delivery operations maintained throughout the rollout
- Reliable sync architecture built for retail-scale transaction volume
Mobile App Delivery
As a mobile-first engagement, Trung Son needed the app itself, not just the backend, to carry the experience, with a focused team accountable for it end to end.
- Native mobile app experience for everyday pharmacy shopping
- Direct communication with Trung Son's internal stakeholders
- Continued app support and iteration post-launch
- Scalable mobile team structure as the platform's needs grew
Business challenges
The core obstacles that shaped every decision we made in rebuilding this platform.
Legacy Data Risk
Years of product, pricing, and customer data lived in a legacy system, with no safe way to migrate it without risking data loss.
ERP Sync Complexity
Keeping ecommerce inventory and pricing consistent with the ERP system, in real time, across every store, required a reliable sync architecture from day one.
Multi-Channel Fragmentation
Web, mobile, and admin experiences needed to function as one connected system, not three disconnected builds.
Zero-Disruption Cutover
Store operations couldn't pause for the migration, the transition had to happen without disrupting on-time deliveries
