Project Context
Client: a full-service beauty salon (hair, nail, spa, eyebrows) in the Mekong Delta with 6–8 staff and 30–40 daily bookings. Problem: all bookings via Zalo and phone, reception staff spending 2–3 hours daily on manual scheduling, ~20% no-show rate, no clear revenue reporting for the owner.
Project Goals
Reduce manual scheduling time. Reduce no-show rate below 10%. Provide real-time dashboard for owner. Create a simple, beautiful booking experience for customers. Launch within 10 weeks.
Architecture Solution
Deemlo Studio designed a multi-role PWA system: Customer app (mobile-first PWA) for browsing and booking. Partner dashboard for managing bookings, staff, services, and reports. Staff module for viewing daily and weekly schedules. Admin panel for system management. Stack: PHP + MySQL backend, vanilla JS frontend, FCM push notifications, PHPMailer.
Results After 8 Weeks
No-show rate dropped from 20% to 7%. Reception scheduling time reduced from 2–3 hours/day to 20–30 minutes. Owner now has weekly revenue and staff performance reports. 35% of bookings made outside business hours — previously completely missed.
Key Lessons
Discovery before code — the first 2 weeks are for asking and listening. Customer data privacy is a real practical concern. Mobile-first is not optional — 92% of customer app traffic came from phones. Automated reminders had the highest ROI of any feature in the project.
