What This Workflow Does

This automation transforms how agencies create client proposals by combining the simplicity of Tally.so forms with the power of GPT-4o AI and Google Slides templates. The workflow captures client requirements through a structured form, processes the information using AI to generate tailored content, and assembles everything into a polished presentation-ready proposal.

Traditional proposal creation is time-consuming and repetitive, often involving copying information between documents and manually customizing templates. This solution eliminates those inefficiencies, reducing proposal creation time from hours to minutes while maintaining high quality and personalization.

How It Works

1. Client Input Collection

The workflow begins when a client or sales team member completes a Tally.so form. This form captures all necessary details about the project scope, budget, timeline, and specific requirements.

2. Data Processing

n8n receives the form submission and structures the data for AI processing. The workflow applies your business rules to categorize the opportunity and determine which proposal template to use.

3. AI Content Generation

GPT-4o analyzes the client input and generates proposal sections tailored to the opportunity. The AI incorporates your agency's value propositions, case studies, and pricing models based on on the project type.

4. Slides Assembly

The workflow populates a Google Slides presentation using your branded template. It populates all content sections, including project approach, deliverables, timeline, and investment details.

Pro tip: Create multiple Google Slides templates for different service lines to maintain brand consistency while allowing for service-specific customization.
