ClientOS
Lead capture and client follow-up, track every lead from first touch to closed.
The challenge
Leads arrive from ads, WhatsApp, forms and phone calls. Without one system, many are never followed up and nobody knows which campaign actually brought the sale.
What we built
ClientOS captures every lead in one pipeline and keeps the sales team on the follow-up: a WhatsApp inbox, a live sales board, goals, a calendar and reports, on the web and on iPhone.

- Lead pipeline from first touch to closed deal
- WhatsApp inbox through the Meta WhatsApp Cloud API and Twilio
- Meta Conversions API, so ad platforms learn which leads became sales
