Your sales team is spending 60% of their time talking to leads who will never buy. According to HubSpot, sales reps waste 2-3 hours every day on leads that aren't ready, willing, or able to purchase - time that could be spent closing deals with qualified prospects. Traditional CRM tools like Salesforce or HubSpot Sales start at ₹2,000-8,000 per user per month. For startups and growing businesses, that's a significant overhead before you've closed a single deal. There's a better way. By combining n8n's workflow automation with WhatsApp Business API and Google Sheets, you can build a fully automated lead qualification bot that works 24/7, scores leads based on your criteria, and delivers only the hottest prospects to your sales team - at a fraction of the cost of enterprise CRM. This guide walks you through the complete architecture: from capturing leads via WhatsApp, through the qualification conversation, to lead scoring and Google Sheets storage, plus automated follow-up sequences and sales team notifications.
The Lead Qualification Problem: Why Manual Processes Fail at Scale
Most businesses face the same challenge: lead volume grows faster than the team's capacity to qualify them. What starts as a manageable inbox of WhatsApp or form leads quickly becomes overwhelming. Sales reps start cherry-picking leads based on gut feel rather than data, promising prospects get lost in the noise, and conversion rates plateau. The cost of poor lead qualification compounds over time.
Architecture Overview: How the n8n Lead Qualification Bot Works
Before diving into the setup, let's map out the complete workflow so you understand how the pieces fit together. The bot handles the entire qualification journey from first contact to sales team notification.
Step 1: Lead Capture
Leads enter the workflow through a WhatsApp message to your business number
Step 2: Qualification Conversation
The bot asks targeted qualification questions and collects answers
Step 3: Lead Scoring
Answers are evaluated against your scoring criteria to generate a qualification score
Step 4: Google Sheets Storage
All lead data, conversation answers, and scores are stored in Google Sheets
Step 5: Routing and Notifications
Hot leads trigger immediate sales team alerts; warm leads enter a nurturing sequence
The 5 BANT Qualification Questions to Ask in Your Bot
The qualification questions you ask determine the quality of your lead scoring. Use the BANT framework (Budget, Authority, Need, Timeline) as the foundation, adding one question specific to your service. Here are the five questions that work best for B2B automation consulting.
Question 1: Budget (What's your monthly investment capacity?)
Opens the conversation professionally while immediately flagging budget mismatches before investing sales time.
- •Frame as 'investment' not 'spend' - positions your service as a value-creator
- •Use button options to avoid ambiguous free-text answers that are hard to score
- •Include a 'Not sure yet' option to capture leads still in evaluation phase
- •This is the most important qualifier - a lead without budget cannot buy, regardless of need
Question 2: Authority (What's your role in this decision?)
Identifies whether you're talking to the decision-maker or someone who needs internal approval - this affects your follow-up strategy.
- •Decision-maker: Go for a direct close in the next interaction
- •Influencer/Recommender: Send a proposal template they can forward internally
- •Researcher: Send a detailed capability document and stay warm
- •Never disqualify based on authority alone - influencers who become champions are valuable
Question 3: Need (What's your biggest automation challenge?)
Identifies the specific pain point and whether your service actually solves it.
- •Match options to your actual service offerings - not generic 'automation'
- •Multiple-selection (list message) works better here than buttons
- •Use the answer to personalise the follow-up message with a relevant case study
- •If their need doesn't match your services, say so - it saves everyone time
Question 4: Timeline (When are you looking to get started?)
Determines urgency and helps prioritise which leads the sales team calls first.
- •'Immediately' leads should be called within 1 hour - put them in the urgent queue
- •'Within a month' leads are ideal prospects - book a call in their calendar via Calendly link
- •'Exploring' leads get added to a monthly newsletter and re-qualified in 90 days
- •Never drop 'exploring' leads - they often convert 3-6 months later when budget is confirmed
Question 5: Company Size (How large is your team?)
Helps segment leads by complexity of implementation and appropriate package tier.
- •Solo/Freelancer: Point to self-serve resources or entry-level packages
- •Small team (2-20): Mid-tier packages, implementation + training
- •Growing company (20-100): Full implementation + ongoing support retainer
- •Enterprise (100+): Custom engagement, route to senior consultant
Google Sheets CRM Setup: The Complete Column Structure
Google Sheets becomes a surprisingly capable lightweight CRM when structured correctly. Here's the exact sheet structure used in our lead qualification bot implementations. This handles up to 500 qualified leads per month with full pipeline visibility for the sales team.
Sheet 1: Active Lead Pipeline
The main working sheet where sales reps track leads from first contact to closed-won
- •Column A: Lead ID (auto-generated: =ROW()-1)
- •Column B: Phone Number (WhatsApp contact)
- •Column C: Name
- •Column D: Lead Score (0-100, colour-coded via conditional formatting)
- •Column E: Category (HOT/WARM/COLD, auto-populated by n8n)
- •Column F: Budget Range
- •Column G: Authority Level
- •Column H: Timeline
- •Column I: Primary Need
- •Column J: Initial Message
- •Column K: Qualified At (timestamp from n8n)
- •Column L: Status (New/Contacted/Proposal Sent/Closed Won/Closed Lost)
- •Column M: Assigned To (sales rep name)
- •Column N: Next Action
- •Column O: Notes
Sheet 2: Conversation Log
Stores the full WhatsApp conversation for each lead - useful for sales context before calling
- •Column A: Lead Phone (foreign key to Pipeline sheet)
- •Column B: Message Direction (Inbound/Outbound)
- •Column C: Message Content
- •Column D: Message Timestamp
- •Column E: Message Type (text/button_reply/list_reply)
Sheet 3: Analytics Dashboard
Auto-calculated metrics to track bot performance and lead quality over time
- •Total leads this month: =COUNTIFS(Pipeline!K:K,">="&DATE(YEAR(NOW()),MONTH(NOW()),1))
- •Hot leads %: =COUNTIF(Pipeline!E:E,"HOT")/COUNTA(Pipeline!B:B)-1
- •Average lead score: =AVERAGE(Pipeline!D2:D1000)
- •Conversion rate (Closed Won): =COUNTIF(Pipeline!L:L,"Closed Won")/COUNTA(Pipeline!B:B)
Automated Follow-Up Sequences by Lead Category
The qualification bot doesn't just capture and score leads - it continues engaging them with relevant content based on their category. Here are the three follow-up sequences you should build in n8n.
Hot Lead Sequence: Same-Day Sales Outreach
Hot leads (score 70+) get immediate human attention. The bot's role is to prepare the sales rep and warm the lead before the call.
- •Immediately after scoring: Bot sends confirmation message to lead with estimated callback time
- •Simultaneously: Alert sent to sales rep on Slack/Telegram with full lead profile
- •If no sales contact within 2 hours: Automated re-alert to sales manager
- •Bot sends Calendly booking link if sales rep does not respond within 4 hours
Warm Lead Sequence: 7-Day Nurture Campaign
Warm leads (score 40-69) need more information before committing. Send a 3-touchpoint nurture sequence over 7 days.
- •Day 0 (immediately): Send relevant case study matching their primary need via WhatsApp
- •Day 3: Send a short explainer video or blog link (e.g., 'How we saved X hours for a company like yours')
- •Day 7: Send a soft CTA - 'Would a 20-minute call be useful to see if we're a fit?'
- •If they engage with any touchpoint, escalate to Hot and trigger immediate sales alert
Cold Lead Sequence: 30-Day Re-Qualification
Cold leads are not dead - they're just not ready. A single educational resource today can become a sale in 30 days.
- •Day 0: Send a useful free resource (guide, checklist) relevant to their stated need
- •Day 30: Re-trigger the qualification bot with a simple message: 'Have your automation plans progressed?'
- •If they re-engage and score higher: Move to Warm sequence
- •After 3 months of no engagement: Archive in Google Sheets (Status: Dormant)
WhatsApp Template Messages for Each Lead Stage
All business-initiated WhatsApp messages must use Meta-approved templates. Here are the exact templates to create in your WhatsApp BSP dashboard for the lead qualification bot. Submit these under the UTILITY category for faster approval and lower per-conversation cost.
Template 1: Welcome & First Qualification Question
Sent immediately when a new lead messages your WhatsApp number. Sets the professional tone and initiates qualification.
- •Template Name: lead_qual_welcome
- •Category: UTILITY
- •Variables: {{1}} = lead name
- •Follow with interactive button message (outside template - user-initiated conversation)
Template 2: Hot Lead Confirmation
Sent to hot leads immediately after qualification. Sets expectations for sales follow-up.
- •Template Name: lead_qual_hot_confirmation
- •Category: UTILITY
- •Variables: {{1}} = lead name, {{2}} = callback timeframe
Template 3: Warm Lead Case Study Follow-Up
Sent to warm leads 24 hours after qualification with relevant social proof.
- •Template Name: lead_qual_warm_followup
- •Category: UTILITY
- •Variables: {{1}} = lead name, {{2}} = case study URL
Template 4: Cold Lead Resource Delivery
Sent to cold leads as an educational touchpoint. Adds value without a hard sell.
- •Template Name: lead_qual_cold_resource
- •Category: UTILITY
- •Variables: {{1}} = lead name, {{2}} = resource URL
Complete n8n Workflow Setup: Nodes and Configuration
Here's the complete node-by-node setup for your lead qualification bot in n8n. This assumes you have n8n Cloud or self-hosted n8n, a WhatsApp Business API account via a BSP (WATI, Interakt, or Meta directly), and a Google account for Sheets.
Node 1: WhatsApp Webhook Trigger
Receives incoming messages from WhatsApp Business Cloud API
Node 2: Extract Message Data
Parse the WhatsApp webhook payload to get phone number, message content, and type
Node 3: Session State Management
Look up the lead's current conversation state in Google Sheets to know which question to ask next
Node 4: Answer Processor & Next Question Router
Records the answer to the previous question and sends the next question based on conversation state
Node 5: Lead Scoring + Pipeline Storage
Calculate final score, categorise lead, and store complete data in the main pipeline sheet
Node 6: Notification Routing
Route completed qualification to sales team (Hot) or nurture sequence (Warm/Cold)
Cost Comparison: n8n Bot vs Traditional CRM
One of the strongest arguments for this architecture is cost. Here's how the n8n + WhatsApp + Google Sheets stack compares to traditional CRM tools for a business qualifying 200 leads per month.
| Component | n8n Stack | HubSpot Starter | Salesforce Essentials |
|---|---|---|---|
| CRM/Pipeline Tool | Google Sheets (Free) | ₹3,500/mo/user | ₹5,500/mo/user |
| Automation Platform | n8n Cloud: ₹1,200/mo | Included | Included |
| WhatsApp Integration | BSP: ₹999-2,499/mo | ₹2,500/mo add-on | ₹3,500/mo add-on |
| Lead Qualification | Included in n8n | ₹1,500/mo (Forms) | ₹2,000/mo |
| Total (1 user) | ₹2,200 - ₹3,700/mo | ₹7,500+/mo | ₹11,000+/mo |
| Total (5 users) | ₹2,200 - ₹3,700/mo (flat) | ₹37,500+/mo | ₹55,000+/mo |
| Setup Complexity | Medium (1-2 weeks) | Low (days) | High (months) |
| Customisability | Fully custom | Limited by platform | Requires developers |
Case Study
How a Mumbai EdTech Startup Cut Sales Costs by 60% with n8n Lead Qualification
Client
EduPath India - Mumbai-based online learning platform selling B2B corporate training packages (₹50K-5L/client)
Challenge
EduPath's inside sales team of 4 was fielding 150-200 WhatsApp and website form leads per month. 70% of these leads were either students seeking individual courses (wrong audience), companies with training budgets under ₹25,000 (below minimum engagement), or contacts with no decision-making authority. The sales team was spending 80% of their time on the 70% that would never buy, causing burnout and missing follow-ups on the 30% that could close. They had evaluated HubSpot but ₹14,000/month for 4 seats was difficult to justify before improving pipeline quality. They needed a qualification layer before leads reached the sales team.
Solution
Tech Arion built a 5-question WhatsApp qualification bot using n8n and WhatsApp Business API in 10 days:
Qualification Questions Customised for EdTech: • Budget: Under ₹25K / ₹25K-1L / ₹1L+ per training programme • Role: HR/L&D Manager / C-Suite / Department Head / Other • Team Size: Under 50 / 50-200 / 200-1,000 / 1,000+ • Training Urgency: Within a month / Quarter / Exploring • Training Type: Compliance / Upskilling / Leadership / Custom
Scoring logic weighted company size and budget most heavily, since these were the primary determinants of deal viability. Google Sheets pipeline was set up with a Kanban-style view using grouped conditional formatting. Hot leads (score 70+) triggered an immediate Slack alert to the senior consultant plus a personalised case study via WhatsApp. The bot handled all initial interactions 24/7 - including leads arriving at 11 PM from HR managers working late.
