TL;DR — pick by use case
- WhatsApp bot: lower friction, no install, ₹15-50K. Best for booking + reminders + transactional messaging.
- Custom app: higher engagement, brand presence, ₹1-3L. Best when retention + repeat is the lever.
- Most service SMBs: start with WhatsApp bot. Add app at 1,000+ active customers.
WhatsApp bot — the lower-friction option
What you build: WhatsApp Business API integration via BSP (Interakt / Wati / Gupshup), with templates for booking, reminders, post-service follow-ups, payments via Razorpay link.
Cost: ₹15-50K build, ₹2-8K/mo running (BSP plan + Meta per-conversation).
Wins on
- Zero install friction — every Indian customer already on WhatsApp
- 5-10x message open rate vs email
- Booking confirmation → payment link → reminders all in one thread
- Works for occasional customers (book once a year)
Loses on
- No persistent brand presence on phone
- Limited UX (text + buttons + simple media)
- Can't push promotional messages outside templates without opt-in
- No loyalty program / membership card UX
Custom mobile app — when retention matters
What you build: native or React Native / Flutter app with booking, profile, history, loyalty / membership, push notifications, payment.
Cost: ₹1-3L build, ₹5-15K/mo running.
Wins on
- Repeat customers (gym, salon, clinic regulars) — app icon = brand on home screen
- Loyalty programs / membership cards
- Push notifications without opt-in friction
- Self-service rebooking, history, preferences
- Better UX for complex flows (multi-step)
Loses on
- Install friction — most customers won't bother for one-off bookings
- Higher build + maintenance cost
- Apple/Google store overhead (app review, in-app purchases tax)
The decision framework
| Your situation | Pick |
|---|---|
| Clinic with mostly first-time + annual patients | WhatsApp bot |
| Clinic with regular check-up patients (yoga, physio, dental hygiene) | WhatsApp + add app at 500+ regulars |
| Salon chain with 1,000+ membership customers | App (loyalty + booking) |
| Restaurant for occasional bookings + delivery | WhatsApp bot |
| Restaurant chain with loyalty club | App + WhatsApp |

Our usual recommendation
Start with WhatsApp bot (₹15-50K). Get to 500+ regular customers. Then build app (₹1-2L) — by then you have data on what features actually matter. WhatsApp builds · App builds
