Here’s a step by step breakdown of how the AI Proposal Generator functions in n8n  

1. Trigger: New Lead Entry  

• A new lead is added to CRM (HubSpot, Salesforce, Pipedrive).  
• n8n detects the trigger and starts the workflow.  

2. Data Fetching  

• Pulls client details (name, industry, past interactions).  
• Retrieves product/service pricing from a database.  

3. AI Content Generation  

• Uses OpenAI’s GPT-4 to draft a personalised proposal based on templates.  
• Ensures tone, structure, and legal compliance.  

4. Approval & Edits  

• The proposal is sent to a manager via Slack/Email for review.  
• If approved → moves to next step. If edits are needed → loops back.  

5. Final Delivery  

• Auto-converts to PDF.  
• Emails to the client or uploads to DocuSign for e-signature.  

6. CRM Update  

• Logs the proposal status back into the CRM.
