WhatsApp CRM
Custom WhatsApp CRM Developer
A shared WhatsApp inbox and CRM for your team, so every customer conversation, lead and follow-up lives in one system you own.
In short
Fasil M builds custom WhatsApp CRMs on the official WhatsApp Business Platform: a shared inbox where the whole team works one number, with contact profiles, tags, sales pipelines, chat assignment, approved broadcasts, AI-suggested replies and reports.

How I can help
When sales and support happen on WhatsApp, customer history often lives on staff phones. When someone leaves, their chats and leads go with them, and managers have no view of response times or lost deals.
I build WhatsApp CRMs that move every conversation onto your official business number and into one shared inbox: chats are assigned to the right person, each contact has a full profile and history, leads move through a pipeline, and reminders make sure nobody is forgotten.
Tools like WATI or Interakt work well for many teams. I build custom when you need your own workflow, deep integration with your ERP or store, data on your own servers, or when per-agent fees no longer make sense.
A great fit for
- Sales and support teams selling or serving customers on WhatsApp
- Businesses whose staff use personal phones for customer chats
- Companies outgrowing per-seat WhatsApp inbox tools

Frequently asked questions

What is a WhatsApp CRM?
A WhatsApp CRM keeps all customer conversations from your business WhatsApp number in one system, alongside contact details, deals and follow-ups, so the whole team can work together and nothing is lost.
How many agents can use one WhatsApp number?
With the WhatsApp Business Platform, there is no practical limit: every agent works from the same number through the shared inbox.
Can you migrate our existing chats and contacts?
Contacts can be imported from spreadsheets or your current CRM. Old chats on personal phones cannot be moved automatically, so new conversations start in the CRM from go-live.
