1.1 Workflow description

Title
Generate AI sales proposals with Gemini and Google Docs
Workflow name
Generate AI sales proposals with Gemini and Google Docs

Generate professional sales proposals from a simple form—AI writes the content, you deliver the document.

Fill out client details, pain points, and pricing, and this workflow creates a polished proposal with calculated ROI metrics, executive summary, solution strategy, and team bios.

How It Works

  1. Sales rep submits a form with client name, industry, pain points, and pricing
  2. Code node calculates ROI, net savings, and break-even period
  3. Gemini AI generates proposal content: executive summary, key challenges, solution strategy, team bios, and call to action
  4. Copies your Google Doc template and replaces all placeholders with generated content
  5. Final proposal is ready in Google Drive

Setup

  1. Import the workflow JSON
  2. Create a Google Doc template with placeholders:
  • {{client_name}}, {{executive_summary}}, {{key_challenges}}
  • {{solution_strategy}}, {{team_bios}}, {{next_steps}}
  • {{formatted_roi}}, {{formatted_net_savings}}, {{formatted_break_even}}
  • {{formatted_solution_cost}}, {{date}}
  1. Add credentials:
  • Google Drive → OAuth2
  • Google Docs → OAuth2
  • Google Gemini → API key from aistudio.google.com
  1. Configure "Copy proposal template" node → Point to your template document
  2. Customize the AI → Edit system message in "Generate proposal content" to match your tone
  3. Test → Submit the form and check the generated proposal
  4. Activate

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/12715/12715.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
