How to run and understand a Bid Comparison

Last updated on November 4, 2025
Overview
The Bid Comparison Tool helps you systematically evaluate and compare vendor proposals against your RFP requirements. Using AI-powered analysis, it scores each vendor across multiple dimensions, identifies compliance gaps, and provides actionable recommendations to help you make informed procurement decisions.
What you'll get:
  • AI-generated executive summary with vendor rankings
  • Detailed requirement-by-requirement scoring for each vendor
  • Compliance and quality metrics for every proposal
  • Comprehensive Excel export with color-coded scores, insights, and recommendations
  • Key strengths, weaknesses, and risk factors for each vendor

Prerequisites

Before using the Bid Comparison Tool, you must first analyze your RFP to extract requirements. The system needs this foundation to compare vendor proposals effectively.

Step 0: Create an RFP Analysis (Required First Step)

  1. Navigate to Opportunities
      • Go to your dashboard and click on Opportunities in the sidebar
      • Browse or search for the RFP/opportunity you want to analyze
  1. Start RFP Analysis
      • Open the opportunity details page
      • Click the "RFP Analysis" or "Create RFP Project" button
      notion image
 
  1. Upload RFP Documents
      • The system will create an RFP project for you
      • Upload all RFP documents (solicitation, specifications, attachments, etc.)
      • Supported formats: PDF, DOC, DOCX
       
      notion image
  1. Wait for Analysis to Complete
      • The system will analyze your RFP documents (typically 3-5 minutes)
      • It extracts requirements, evaluation criteria, compliance items, scope of work, and other key sections
      • You'll see a status indicator showing "Processing" → "Completed"
      • Once completed, you should see a completed analysis/.
      notion image
  1. Review Extracted Requirements (Optional)
      • Once analysis is complete, review the extracted requirements
      • The system identifies key requirements like evaluation criteria, compliance mandates, technical specifications, etc.
      • Note: Make sure the analysis is complete before proceeding to bid comparison
Important: The Bid Comparison Tool requires a completed RFP Analysis because it compares vendor proposals against the requirements extracted from your RFP. Without this foundation, the tool cannot perform meaningful comparisons.

End-to-End Bid Comparison Workflow

Step 1: Create a New Bid Comparison

  1. Navigate to Bid Comparison Tool
      • From your dashboard, click "Bid Comparison Tool" in the left sidebar
      • You'll see a list of all your existing bid comparisons

        • Description: (Optional) Add context about this comparison
        • Select RFP Project: Choose the RFP project you analyzed in Step 0
          • This links your comparison to the extracted requirements
          • Only completed RFP analyses will appear in the dropdown
        • Click "Create Bid Comparison"
        notion image

    Step 2: Upload Vendor Proposals

    After creating your comparison, you'll be taken to the comparison detail page where you can upload proposal files.
    1. Prepare Your Proposal Files
        • Gather all vendor proposal documents
        • Supported formats: PDF, DOC, DOCX
        • Each file represents one vendor's complete proposal response
    1. Upload Proposal Files
        • In the "Upload Vendor Proposals" section:
          • Vendor Name: Enter the vendor's name (e.g., "Acme Corporation")
          • Proposal File: Click to select the vendor's proposal document
        • Click "Upload Proposal"
        • Repeat for each vendor (typically 3-10 vendors)
        notion image
    1. Verify Uploaded Files
        • Uploaded proposals appear in the "Proposal Files" section
        • Each file shows:
          • Vendor name
          • File name
          • Upload status ("pending" initially)
        notion image
    Tip: Upload all proposals before starting the comparison to get a complete analysis in one run.

    Step 3: Start the Comparison Analysis

    1. Review Your Setup
        • Ensure all vendor proposals are uploaded
        • Confirm the linked RFP project is correct
    1. Start the Analysis
        • Click the "Start Comparison" button.
        • The system will begin processing (this may take 5-30 minutes depending on the number of requirements and proposals)
        notion image
    1. Monitor Progress
        • The status will change from "Pending" to "Processing" in about 1 min. Don’t repress the “Start Comparison” button. Instead refresh the page if you don’t see the latest processing status.
        • A progress indicator appears at the top of the page
        • The page automatically refreshes every 5 seconds to show updated status
        • You can safely navigate away and return later - the analysis continues in the background.

    What happens during processing:
    • The system parses each proposal document
    • Extracts relevant sections from each vendor's response
    • Scores each vendor against each RFP requirement on 4 dimensions:
      • Compliance: Does the response meet the requirement?
      • Quality: How well is the requirement addressed?
      • Evidence: Is there proof/documentation supporting the response?
      • Clarity: How clear and complete is the response?
    • Calculates weighted scores based on requirement importance
    • Generates an AI-powered executive summary with recommendations
    • Compiles everything into a comprehensive comparison report

    Step 4: Review Results

    Once processing is complete (status changes to "Completed"), you can review the comprehensive analysis.

    4.1 Executive Summary

    At the top of the results, you'll see an AI-generated executive summary that includes:
    • Overview: 2-3 sentence summary of the comparison
    • Top Vendor Rankings: Ranked recommendations with:

    Key Features Explained

    Intelligent Requirement Weighting

    Not all requirements are equal. The system automatically assigns weights based on:
    Content Type Weights:
    • Evaluation Criteria (2.0x) - Highest priority
    • Compliance Requirements (1.5x) - Critical for eligibility
    • Technical Requirements (1.5x) - Core capabilities
    • Scope of Work (1.2x) - Important context
    • Other Requirements (1.0x) - Standard priority
    Keyword Modifiers:
    • Words like "must," "shall," "required" → +0.3 boost
    • Words like "optional," "preferred" → 0.2 reduction
    This ensures critical requirements have more impact on the overall score.

    Multi-Dimensional Scoring

    Each requirement is evaluated on 4 dimensions:
    1. Compliance (0-10): Does it meet the requirement?
    1. Quality (0-10): How well is it addressed?
    1. Evidence (0-10): Is there supporting documentation?
    1. Clarity (0-10): How clear and complete is the response?
    The overall score for each requirement is the average of these 4 dimensions.

    AI-Powered Insights

    The system uses advanced AI models to:
    • Extract relevant proposal sections using semantic search
    • Score proposals with contextual understanding
    • Generate executive summaries and recommendations
    • Identify concerns, red flags, and strengths
    • Provide actionable decision factors

    Best Practices

    For Best Results:

    1. Complete RFP Analysis First
        • Always analyze your RFP before creating a bid comparison
        • Ensure all RFP documents are uploaded for comprehensive requirement extraction
    1. Upload Complete Proposals
        • Include the full proposal document, not just excerpts
        • If a vendor submitted multiple files, consider combining them into one PDF
    1. Use Descriptive Vendor Names
        • Use official vendor names for clarity (e.g., "Acme Corporation" not "Vendor 1")
        • Consistency helps when reviewing and exporting results
    1. Review in Context
        • Use the AI insights as a starting point, not the final decision
        • Review the detailed scores and reasoning for critical requirements
        • Consider factors outside the RFP (pricing, past performance, etc.)
    1. Export Early and Often
        • Download the Excel file after each analysis
        • Share with stakeholders for collaborative review
        • Keep records for procurement documentation

    Collaboration Tips:

    • Share the Excel Export: The file is designed for easy sharing and collaborative review
    • Focus Stakeholder Attention: Direct evaluators to specific sheets (Summary for executives, Detailed Scores for technical reviewers)
    • Document Decisions: Add notes in the Excel file to capture team discussions and decisions

    Frequently Asked Questions

    Q: How long does the analysis take?
    A: Typically 5-15 minutes depending on:
    • Number of vendors (3-10 typical)
    • Number of requirements (30-80 typical)
    • Size of proposal documents
    Q: Can I add more proposals after starting the comparison?
    A: Yes, but you'll need to click "Regenerate" to re-run the analysis with the new proposals.
    Q: What if a vendor's score seems incorrect?
    A: Review the detailed reasoning in the Excel export. The AI explains each score. Remember that scores are based solely on how well the proposal addresses the RFP requirements as written.
    Q: Can I adjust requirement weights?
    A: Currently, weights are automatically assigned based on requirement type and keywords. Custom weighting is planned for a future release.
    Q: What file formats are supported?
    A: PDF, DOC, and DOCX for both RFP documents and proposal files.
    Q: How much does each comparison cost?
    A: Processing costs are built into your subscription. Typical cost per comparison is approximately $0.50-$1.50 depending on the number of proposals and requirements.
    Q: Is my data secure?
    A: Yes. All documents are securely stored with workspace-level access controls. Only users in your workspace can view your bid comparisons.
    Q: Can I compare proposals without an RFP analysis?
    A: No. The system needs extracted requirements from your RFP to perform meaningful comparisons. Always complete the RFP analysis first (Step 0).

    Troubleshooting

    Problem: "No requirements found" error
    Solution: Ensure your linked RFP project has been analyzed and completed. Return to the RFP project page and verify the analysis status.
    Problem: Comparison stuck in "Processing" status
    Solution: Large proposal sets may take up to 15 minutes. If it's been longer, refresh the page. If the issue persists, contact support at fred@narwin.ai.
    Problem: Some scores seem low across all vendors
    Solution: This may indicate:
    • The requirement wasn't clearly addressed in any proposal
    • The RFP requirement was ambiguous or broad
    • Vendors may need to provide clarifications
    Review the reasoning in the Excel export for specific guidance.
    Problem: Can't find my RFP project in the dropdown
    Solution: Only completed RFP analyses appear in the list. Make sure your RFP project shows "Completed" status before creating a bid comparison.
    Problem: Export button doesn't work
    Solution: Ensure the comparison status shows "Completed." You can only export after the analysis finishes.
