Voice + WhatsApp = Closed Loops

Two-channel sequences: call to qualify → WhatsApp to confirm + pay.

When someone raises a hand on your site, urgency fades by the hour. Email is slow; chat alone misses “talk now.” The highest-converting path is a closed loop: a quick AI call to qualify and agree the next step, followed by a WhatsApp card that confirms details, adds directions or a quote, and (crucially) lets the customer pay or reschedule with one tap. Below is the playbook we deploy to make that loop reliable, compliant, and measurable.

Why voice + WhatsApp beats any single channel

Speed-to-lead: An AI caller reaches out within minutes to acknowledge the request and offer helpful defaults (“Quick price range now or book a 10-min slot?”). See AI Callers.
Action in-thread: WhatsApp is where the customer finishes the job—time pickers, quote approvals, and payment links live comfortably there. Explore WhatsApp solutions.
Perfect records: Every call outcome and WhatsApp tap is logged to the contact/deal in InOne CRM for SLAs, reporting, and audits.
After-hours coverage: Your AI Receptionist catches inbound calls, books valid slots, and kicks off the same WhatsApp follow-ups.

Interesting AI fact: Small speech models detect urgency cues (“today”, “before Friday”) in under 500 ms, letting the caller bias the earliest valid slot automatically.

The core two-channel sequence (copy this)

Capture with context (web → chat).
Add a high-intent launcher to pricing and service pages via WhatsApp Website Integration so the first message carries page + UTM info.
AI call to qualify (SLA: ≤5 min).
Using AI Callers, confirm Need and Timing with friendly BANT-style prompts, then:
- If free now → book on the call against live calendars in InOne CRM.
- If busy → send a WhatsApp card with three times to choose.
WhatsApp confirm + pay.
The bot drops a card with: chosen time, map link, prep checklist, and a secure payment or deposit link when applicable. If the case is sales, include “Approve quote”.
Reminders that prevent no-shows.
Use T-24h and T-2h WhatsApp nudges with “Reschedule” and “Directions” buttons. Outside the 24-hour service window, send approved templates (kept tidy in your FAQ library).
Closed loop & audit trail.
Conversation, templates, consent timestamps, payments, and outcomes are stored automatically in InOne CRM—no spreadsheets.

Variations that win across teams

Clinics: AI call confirms symptoms + timing → WhatsApp sends what-to-bring and location. Deposit collected to reduce no-shows.
Real estate: AI receptionist books viewing → WhatsApp card with photos + docs list; “I’m outside” quick reply on the day.
Automotive: AI call proposes test-drive → WhatsApp asks for VIN/photos for trade-in and shares route + checklist.

Guardrails (South Africa-ready)

POPIA by design: Short purpose lines (“so we can confirm your booking”), minimal data, and consent timestamps written to the CRM.
Template discipline: Business-initiated WhatsApp templates after 24h with a clear opt-out (we manage this in your template library).
Action whitelist: Bots and callers may book, send quotes, request docs, and trigger payment links—nothing off-policy.
Human-in-the-loop: Low confidence or VIPs trigger a warm transfer with the last 5–10 turns attached so nobody repeats themselves.
