GTG CRM will use the Spa industry as an example for this case study. The spa industry in Vietnam has a low customer retention rate, with an average of only 30-40% of customers returning after their first visit. The reason? Not poor service, but rather the lack of a post-service care system: forgotten reminders, no birthday promotions, no follow-up with new customers.
Spa Problems
- Managing customers with notebooks/Excel: Cannot quickly find customer service history
- Manual appointment reminders: Staff forget to call → customers forget appointments → wasted empty slots
- Don't know who VIP customers are: Don't know who spends the most, who hasn't visited in a long time
- Missing special occasions: Birthdays, anniversaries, upsell opportunities are missed
- No data: Which services sell well? Which staff have the most returning customers? Don't know.
GTG CRM - Comprehensive CRM Solution for Spas
1. 360° Customer Profile
Each customer has a complete profile:
- Personal information: Name, Phone, email, date of birth, oily/dry/combination skin
- Service history: All spa visits, services used, serving staff
- Spending history: Total spending, average value per visit
- Professional notes: Allergies, preferences, special requests
- Last interaction: Last message, email, call

2. Automatic Appointment Reminders
Set up automation:
- 24 hours prior: Send Zalo/SMS message to remind of appointment
- 2 hours prior: Send final confirmation message
- After service: Send thank you message + review link
- No-show customers: Automatically send message inviting to rebook
Automation Workflow:
Booking created → 24h reminder → 2h confirmation → Completed → Thank you + Review
↓ (after 7 days)
Suggest next service
3. Smart Customer Segmentation
Automatically segment customers:
| Segment | Criteria | Action |
|---|---|---|
| VIP | Spending > 5 million/month | Special offers, personalized care |
| Loyal | Visits > 3 times/month | Membership cards, points accumulation |
| New | Visited only 1 time | Follow-up invite to return + voucher |
| Dormant | Has not visited > 60 days | Automated "win-back" campaigns |
4. Online Booking (via Website/Zalo)
- Customers book via website (GTG CRM's landing page builder)
- Or book via Zalo with AI chatbot support
- System automatically checks for available slots → confirms → creates booking
5. Email & SMS Marketing
Send automated marketing campaigns:
- Birthday: Send discount voucher 3 days before birthday
- Service suggestions: Based on history → suggest suitable services
- Promotions: Send to the right customer segments (VIP, new, dormant)
- Newsletter: Share skincare tips, new products

- 200 customers/month, retention rate: 35%
- Manual appointment reminders: staff forgot 20% of appointments
- Didn't know who VIP customers were

After 3 months using GTG CRM:
- Retention rate: 55% (+57%)
- No-shows reduced from 20% to 5% (thanks to auto reminders)
- Revenue increased by 25% through targeted upsells
- Saved 2 hours/day thanks to automation
