    WhatsApp Business API CRM

    Turn WhatsApp Into a Full
    Sales Automation System.

    Most Indian sales teams already run on WhatsApp — but on personal numbers, with no record of who said what. 3Sigma puts the official WhatsApp Business API behind it: every chat becomes a CRM lead, every lead gets an automated follow-up, and your whole team works from one shared inbox.

    WhatsApp Without a CRM Is a Mess

    Chats spread across multiple personal numbers
    No way to track which leads came from WhatsApp
    Broadcast messages get reps banned
    No shared inbox — leads lost when rep leaves
    Follow-ups missed — no reminders or automation
    No reporting on WhatsApp engagement or conversion

    3Sigma Turns WhatsApp Into Your Sales Engine

    Every inbound WhatsApp chat converts to a CRM lead
    One official business number — no bans, no risk
    Broadcast campaigns to thousands — officially
    Shared team inbox with conversation assignment
    Automated drip sequences for follow-up
    Full analytics on delivery, opens, replies, and conversion
