System Prompt

You are a lead qualification specialist. Your goal is to understand the prospect's needs, qualify them, and schedule a meeting with sales if they're a good fit.

## Qualification Criteria (BANT)

### Budget
- What budget range are they working with?
- Are they decision-makers on budget?

### Authority
- What is their role?
- Who else is involved in decisions?

### Need
- What problem are they trying to solve?
- How urgent is it?

### Timeline
- When are they looking to implement?
- Is there a specific deadline?

## Qualification Questions

Ask these naturally throughout the conversation:

1. "What brings you to [Company] today?"
2. "Tell me about your current situation with [problem area]"
3. "What would solving this problem mean for your business?"
4. "Who else would be involved in evaluating solutions?"
5. "What's your timeline for making a decision?"
6. "Do you have a budget range in mind?"

## Scoring Guidelines

**Hot Lead (Score 80-100)**
- Clear budget authority
- Decision-maker or strong influencer
- Urgent need (within 30 days)
- Specific pain points that match our solution

**Warm Lead (Score 50-79)**
- Budget being discussed
- Part of buying committee
- Timeline within 90 days
- General interest, exploring options

**Cold Lead (Score 0-49)**
- No budget authority
- Just researching
- No timeline
- Needs we can't address

## Response Style
- Be conversational, not interrogative
- Listen actively and respond to what they say
- Don't rapid-fire questions
- Share relevant info about our solution when appropriate
- Be enthusiastic but not pushy

## Handling Objections

"I'm just looking":
→ "Totally understand! What sparked your interest today?"

"We don't have budget":
→ "Makes sense. When do budget discussions typically happen?"

"I need to talk to my team":
→ "Of course! What would be most helpful for me to share with them?"

## Next Steps

For qualified leads:
→ "Based on what you've shared, I think there's a great fit. Would you be open to a 15-minute call with our solutions team to dive deeper?"

For unqualified leads:
→ "Thanks for sharing! It sounds like timing isn't quite right. Can I send you some resources to review?"

Lead Scoring Logic

type LeadScore struct {

    Authority int // 0-25
    Need      int // 0-25
    Timeline  int // 0-25
}

func calculateScore(lead *Lead) int {
    var score LeadScore

    // Budget scoring
    switch lead.Budget {
    case "over_50k":
        score.Budget = 25
    case "25k_50k":
        score.Budget = 20
    case "10k_25k":
        score.Budget = 15
    case "under_10k":
        score.Budget = 10
    default:
        score.Budget = 5
    }

    // Authority scoring
    switch lead.Role {
    case "ceo", "cto", "vp":
        score.Authority = 25
    case "director":
        score.Authority = 20
    case "manager":
        score.Authority = 15
    case "individual":
        score.Authority = 10
    default:
        score.Authority = 5
    }

    // Need scoring
    if lead.Needs != "" && strings.Contains(lead.Needs, "urgent") {
        score.Need = 25
    } else if lead.Needs != "" {
        score.Need = 15
    } else {
        score.Need = 5
    }

    // Timeline scoring
    switch lead.Timeline {
    case "immediate", "this_month":
        score.Timeline = 25
    case "this_quarter":
        score.Timeline = 20
    case "this_year":
        score.Timeline = 10
    default:
        score.Timeline = 5
    }

    return score.Budget + score.Authority + score.Need + score.Timeline
}

Conversation Flow

1. Greeting & Permission
   ↓
2. Understand Situation (Need)
   ↓
3. Explore Impact (qualify need)
   ↓
4. Discuss Decision Process (Authority)
   ↓
5. Timeline Discussion
   ↓
6. Budget (if appropriate)
   ↓
7. Score & Route
   ├─ Hot (80+) → Schedule meeting
   ├─ Warm (50-79) → Send resources + follow-up
   └─ Cold (<50) → Thank + nurture

Outbound Lead Qualification

For outbound campaigns, use variables to personalize:

curl -X POST https://voice-agent.edesy.in/api/v1/calls \
  -d '{
    "agent_id": "lead_qualifier",
    "to": "+1234567890",
    "variables": {
      "leadName": "Sarah",
      "company": "Acme Corp",
      "triggerEvent": "downloaded whitepaper",
      "salesRep": "John from Sales"
    }
  }'

Outbound Greeting:

Hi {{leadName}}! This is Alex from [Company]. I noticed you {{triggerEvent}} recently and wanted to reach out. Do you have a quick minute?

Analytics

type QualificationMetrics struct {
    TotalCalls           int
    QualifiedLeads       int
    MeetingsScheduled    int
    AverageCallDuration  time.Duration
    AverageLeadScore     float64
    QualificationRate    float64
    ConversionRate       float64
}

func trackQualification(call *Call, lead *Lead) {
    metrics.Increment("leads.calls.total")
    metrics.Histogram("leads.score", float64(lead.Score))
    metrics.Histogram("leads.call_duration", call.Duration.Seconds())

    if lead.Score >= 50 {
        metrics.Increment("leads.qualified")
    }

    if call.MeetingScheduled {
        metrics.Increment("leads.meetings.scheduled")
    }
}

Best Practices

1. Natural Conversation Flow

// Don't rapid-fire questions
badFlow := []string{
    "What's your budget?",
    "What's your timeline?",
    "Who makes decisions?",
}

// Build on their responses
goodFlow := `
Lead: "We're struggling with X"
You: "I hear that a lot. Tell me more about how X is affecting your business..."
Lead: [shares more]
You: "That sounds challenging. What would solving this mean for your team?"
`

2. Handle "Not Interested"

notInterestedResponses := map[string]string{
    "timing": "Totally understand. Would it be helpful if I sent some resources for when timing is better?",
    "competitor": "Got it! Just curious - what drew you to [competitor]?",
    "budget": "Makes sense. Budgets are tight everywhere. When do planning cycles typically happen?",
}

3. Capture Information Naturally

// Extract info from conversation, don't ask directly
func extractLeadInfo(transcript string) *Lead {
    // Use LLM to extract structured data from natural conversation
    prompt := `Extract lead information from this conversation:
    - Name
    - Company
    - Role
    - Budget signals
    - Timeline
    - Pain points
    - Decision process`

    return llm.Extract(transcript, prompt)
}
