Business challenge
The organiser ran a proven offline event — strong speaker lineup, solid sponsor roster. Digital registration was the bottleneck.
- 12% ad → registration conversion — email confirmation flow lost users between landing page and inbox
- 180+ support calls on event day — venue, parking, session timing, badge collection
- 8% arrived without tickets — PDF lost in email, spam folder, or wrong device
- 34% email open on speaker swap — last-minute agenda change missed two-thirds of attendees
- Sponsor lead follow-up at 40% within 24h — manual business card collection delayed revenue for exhibitors
Email and web forms work for B2B — but Indian professionals live on WhatsApp. The organiser needed registration where attendees already are.
Solution architecture
Deployment followed an 8-week rollout mapped to event milestones:
- 8 weeks out: Click-to-WhatsApp ads → registration bot collecting name, company, ticket tier
- 6 weeks out: Razorpay payment link in-bot → on capture: QR ticket + venue map + calendar invite
- 2 weeks out: FAQ bot trained on venue, parking, hotels, dress code, WiFi
- Event week: Segment broadcasts by ticket type (VIP, standard, exhibitor)
- Post-event: WhatsApp feedback form + sponsor lead routing within 24h
Payment integration: Razorpay + WhatsApp guide. Onboarding: API checklist.
WhatsApp registration flow
Ad click to paid ticket
Meta Click-to-WhatsApp ad → bot greets with event name and date → collects name, company, email → presents ticket tiers (Early Bird / Standard / VIP) → sends Razorpay payment link → on payment.captured: QR ticket image + Google Maps pin + .ics calendar file.
Median time from ad click to paid registration: 4.2 minutes vs 11 minutes on the legacy landing page flow.
Day-of operations
Session running 20 minutes late in Hall B → broadcast to Hall B segment only → updated agenda link. Emergency venue change reached 94% of attendees in 8 minutes vs 34% email open rate on the prior edition's equivalent alert.
FAQ bot handled 78% of "where is registration desk?" and "parking?" queries without human agents.
Exhibitor lead capture
Booth QR scan → instant brochure PDF + "Book a meeting" button → routed to sponsor sales rep inbox in Ominiflow. 92% of sponsor leads followed up within 24h vs 40% with manual card collection.
