Turn WhatsApp Into a 24/7 AI Sales Machine (With Code)

Your business gets WhatsApp messages at 3am. Nobody answers. Lead lost.

I built a bot that handles this automatically — qualifies leads, answers questions, and sends payment links. Here is the architecture.

The Stack

• 
  Baileys (WhatsApp Web protocol, no Meta API needed)


• 
  Claude API for intelligent responses


• 
  SQLite for CRM (contacts, lead scores, conversation history)


• Zero external dependencies. Runs on a $5 VPS.

How It Works

// Message comes in

sock.ev.on("messages.upsert", async ({ messages }) => {

  const msg = messages[0];

  const text = msg.message?.conversation || "";

  const from = msg.key.remoteJid;



  // Track in CRM

  crm.trackContact(from, text);



  // AI generates response with context

  const history = crm.getHistory(from, 20);

  const response = await claude.chat({

    system: salesPrompt,

    messages: history

  });



  // Send reply

  await sock.sendMessage(from, { text: response });



  // Auto-detect buying intent

  if (response.includes("payment")) {

    crm.updateStage(from, "closing");

  }

});

Built-in CRM

Every contact gets:

• 
  Lead score (0-100) based on buying signals


• 
  Sales stage: new → interested → qualified → closing → converted


• 
  Tags: auto-applied (lead, hot-lead, customer)


• 
  Full conversation history for AI context
  

CREATE TABLE contacts (

  phone TEXT PRIMARY KEY,

  name TEXT,

  lead_score INTEGER DEFAULT 0,

  stage TEXT DEFAULT "new",

  tags TEXT DEFAULT "",

  messages_count INTEGER DEFAULT 0,

  first_seen INTEGER,

  last_seen INTEGER

);

Sales Automation

The AI handles the full funnel:

1. 
   Greeting — warm, asks about needs


2. 
   Qualification — understands budget/timeline


3. 
   Objection handling — addresses concerns naturally


4. 
   Closing — sends payment link at the right moment


5. 
   Follow-up — checks in after 24h silence

Not pushy. Not robotic. It builds genuine trust.
