AI-Powered Roofing Quote Automation System

A Belgium-based roofing and renovation company receives frequent quote requests through its website. Each request previously required a manually written estimate — slow, error-prone, and hard to scale.

Delays in responses, inconsistent pricing language, and dependency on team availability were slowing down sales and reducing conversion rates.

The goal was to build a fully automated, AI-driven quoting system that delivers accurate, professional roofing estimates instantly — without increasing manual workload.

Manual quote writing for every incoming request

Response times of 2–3 hours per lead

Inconsistent pricing logic and tone between quotes

High dependency on staff availability

No centralized system for tracking generated quotes

Limited scalability during high demand periods

I built a complete AI-powered quote automation system using Zapier, OpenAI (GPT-4o), Google Sheets, Elementor Forms, and Gmail.

The system automatically generates structured, client-ready roofing quotes in French — based on real pricing logic, materials, urgency, and surface area.

1. Lead Form Submission Clients submit roofing project details via Elementor Forms on the website.

2. Webhook Trigger Form data is instantly sent into Zapier via Webhook.

3. Data Logging All lead information is stored in Google Sheets for tracking, auditing, and backup.

4. Context Injection A predefined technical block is pulled from Google Sheets, including:

Roofing materials and pricing references

Payment terms and guarantees

Standard professional phrasing from real quotes

5. AI Quote Generation (GPT-4o) OpenAI generates a full roofing quote in French, including:

Dynamic price calculations (materials, surface size, scaffolding)

Urgency-based cost adjustments

Professional structure (sections, disclaimers, payment plans)

6. Spreadsheet Update Generated quote and timestamp are written back into the lead record.

7. Automated Email Delivery The finalized quote is instantly sent via Gmail to the sales inbox for client follow-up.

⚡ Quote generation reduced from 2–3 hours to under 30 seconds

📄 100% consistency in tone, structure, and pricing logic

🤖 Fully automated process — no manual input after form submission

📈 Higher response speed and improved conversion potential

🧱 Scalable system handling more requests with the same team size
