The Problem

Conversations live in personal phones while revenue leaks

Leads message at night and wait until morning. Agents work from unverified numbers, templates get rejected, and nobody can report on response time or deal source.

  • Personal WhatsApp numbers create compliance and continuity risk.
  • No shared inbox means duplicate replies and missed follow-ups.
  • Campaigns are sent without opt-in hygiene or template approval.
  • Conversation data never reaches the CRM or revenue reporting.

Frequently Asked Questions

Service FAQs

Will our existing WhatsApp number be lost?

No. We migrate an eligible number to the official Cloud API after business verification. Message history on the old consumer app should be exported beforehand.

Is broadcast messaging allowed?

Only with documented opt-in and approved templates. We build suppression and consent tracking so campaigns stay within Meta policy.

Can agents still reply manually?

Yes. Automation handles routing, reminders, and repetitive replies while agents take over any conversation from the shared inbox.
