Shared WhatsApp inbox
One business number on the official WhatsApp Cloud API, answered by the whole team from a browser, with each chat assigned to a person and nothing living on a personal phone.
WhatsApp CRM
Most Indian businesses already sell on WhatsApp. The trouble starts when three salespeople answer from their own phones, nobody knows which lead was followed up, and the chat history leaves with the person who quits. A WhatsApp CRM puts every chat on one business number, ties it to a lead with a stage and a follow-up date, and shows the owner what is happening. You can rent one (WATI, Interakt, AiSensy, Gallabox) or have one built around how you sell. This page explains both, and what I build when renting doesn't fit.
01
What I build
Every chat linked to a lead
A new WhatsApp conversation creates or updates a lead, matched by phone number, with source, stage, deal value and the full message history on one page.
Follow-ups and approved templates
A follow-up date on every lead, today's list for each salesperson, and Meta-approved templates for reminders, quotes and payment links once the 24-hour window closes.
Bots, routing and reports
An optional AI or menu bot for the first reply, round-robin assignment, and reports on response time, leads by source and won value.

What I design for
These are the problems that came up on real projects, and the ones I plan for before writing code.
Staying within WhatsApp's rules
Built on the official API with opt-in and approved templates, so your number isn't flagged or banned the way bulk-sender tools get banned.
No per-agent fee
Rented WhatsApp CRMs charge per month and often per agent. A custom one costs hosting and Meta's message fees, whether you have 2 salespeople or 20.
Your sales process, not a template
Stages, fields and rules match how you actually sell: site visits, demos, trial classes, deposits or installations.
Your data stays yours
Chats and leads sit in your own database, exportable any time, and connect to your website, Sheets, payments or an existing CRM.
05
Tools I use
- WhatsApp Cloud API
- TypeScript
- n8n
- PostgreSQL / SQLite
- Cloudflare
- OpenAI / Claude
- Google Sheets
- Docker
06
Is it a fit?
A good fit for teams of 2–20 who sell mainly on WhatsApp, have outgrown personal phones and spreadsheets, and have a process the rented tools only half fit.
Not a fit if WATI, Interakt, AiSensy or Gallabox already works for you. At ₹1,500–3,000 a month they are cheaper than any custom build for a simple inbox and broadcasts. I'd rather connect automation to them than replace them.

Questions people ask
What is a WhatsApp CRM?
Software that connects your WhatsApp Business number to a customer database: every chat is tied to a lead or customer, the team shares one inbox, and follow-ups, stages and reports live in one place instead of on personal phones.
Custom WhatsApp CRM or WATI / Interakt / AiSensy?
Rent one if you mainly need a shared inbox, broadcasts and a simple bot. Those tools cost ₹1,500–3,000 a month plus message fees and are quick to start. Build a custom one when you need your own pipeline stages, deeper reports, integrations with your systems, or when per-agent fees start adding up.
Does it use the official WhatsApp Business API?
Yes. Business numbers in a CRM run on Meta's official Cloud API with approved templates. Unofficial libraries are fine for personal experiments but risk bans for a business number.
How much do WhatsApp messages cost?
Replies within 24 hours of a customer messaging you are free. Template messages you start cost ₹0.115 (utility) or about ₹0.86 (marketing) each, plus GST, paid directly to Meta.
Can it connect to my existing CRM instead?
Yes. If you already use Zoho, HubSpot or LeadSquared, WhatsApp chats and leads can sync into it, which is usually cheaper than a new CRM. See WhatsApp automation for that kind of setup.
