Custom system · WhatsApp & AI
A WhatsApp CRM that knows your store, and answers like your best staff.
A shared team inbox on the official WhatsApp Cloud API, with an AI assistant that checks live stock, tracks orders and hands over to a human when it should.
Built for Darussalam · 4 Shopify stores, one shared WhatsApp inbox
One-time build from $100. No app subscription. You own the code.
Why they came to us
In the client's own words.
Our team answers hundreds of WhatsApp messages a day, mostly the same questions: is this in stock, where is my order.
The WhatsApp tools I found charge monthly, cap how many of my team can log in, and charge extra just to connect Shopify.
None of them could look at a photo of a book cover and tell the customer if we have it.
I wanted something that works for all four stores, speaks like us, and doesn't charge more every time the team grows.

How the WhatsApp CRM works, day to day.
- 1
Step 1
See the day at a glance
The overview opens on today: new contacts, delivery rate, how many chats the bot answered, carts waiting at checkout and messages sent.

Step 2
A customer messages the store
"Do you have this book in stock?" The chat lands in the shared inbox for the right store, with the 24-hour reply window counting down and quick replies one tap away.

Step 3
The AI assistant answers
It searches the live catalogue, replies with stock, price and rating, and sends a checkout link. The team can pause it, test it on chosen numbers and get alerts, without a developer.

Step 4
The catalogue, inside the CRM
Every book synced from Shopify with stock and sale prices, so the team can send the right product without leaving the chat.

Step 5
Win back abandoned carts
Checkouts left behind show up with their value and the customer's WhatsApp number. One click sends a reminder with their own cart link.

Prices from each app's Shopify App Store listing or the vendor's pricing page, checked 26 October 2026, monthly billing unless noted. Tap an app to check it yourself.

Under the hood
Built properly, and kept secure.
Architecture
- Official Meta WhatsApp Cloud API in coexistence mode, so the number still works in the phone app.
- Webhooks land in a Supabase edge function, stored in Postgres, pushed live to the web app.
- AI replies run server-side with Claude, using tools for stock, orders and checkout links.
Security
- Every Meta webhook signature verified, unsigned requests rejected.
- Tokens and keys server-side only, never in the browser.
- Row-level security on conversations and customers.
Tech stack
- TanStack Start
- React 19
- Supabase
- Edge Functions
- Meta WhatsApp Cloud API
