A vendor comparison matrix scores each vendor on 6-10 criteria, applies weights based on how important each criterion is to your business, and produces a total weighted score that makes the best choice clear and defensible. Without it, vendor decisions rely on whoever spoke last in the meeting or whoever has the strongest opinion. At aidowith.me, the Tables, Plans, and Checklists route covers this in 10 steps over about 45 minutes. You'll define your evaluation criteria, assign weights, collect vendor data, use AI-generated formulas to calculate weighted scores, and build a summary recommendation that explains the top choice. The matrix works in Google Sheets or Excel. AI writes all the SUMPRODUCT formulas and the conditional formatting rules that color-code scores above and below threshold. A stakeholder weight-averaging exercise at the start aligns everyone on priorities before the evaluation begins.

The Problem and the Fix
Without a route
- Your last vendor selection was contested by 2 stakeholders because there were no documented criteria: just opinions
- You've compared 5 vendors but can't present the recommendation without a 20-minute explanation of the reasoning
- Different team members weight price vs. features differently and the discussion goes in circles without a shared scoring framework
With aidowith.me
- Build a weighted scoring matrix in one 45-minute session that produces a clear vendor recommendation with a numerical score
- Align stakeholders on criteria and weights before evaluation so the scoring result is defensible without a long debate
- Show the final comparison in one spreadsheet view that a decision-maker can understand in under 5 minutes

How It Works
Define criteria and assign weights
List 6-10 evaluation criteria (price, integration, support quality, compliance, scalability, user experience) and assign a weight percentage to each. Weights must total 100%. AI helps you pick weights based on your stated business priorities.
Collect vendor scores and build the formula
Score each vendor 1-5 on each criterion based on demos, reviews, and documentation. AI writes the SUMPRODUCT formula that calculates the weighted total for each vendor and applies conditional formatting.
Generate the recommendation summary
AI writes a 200-word recommendation that explains the top scorer, notes the second-place option and why it lost, and highlights the 2-3 criteria that drove the decision.

Questions
Define 6-10 evaluation criteria, assign weights totaling 100%, score each vendor 1-5 on each criterion based on demos and documentation, and use a SUMPRODUCT formula to calculate weighted totals. AI writes the formula and conditional formatting. The aidowith.me Tables, Plans, and Checklists route covers all 10 steps in about 45 minutes, including a stakeholder weight-alignment exercise.
Six to ten criteria. Fewer than 6 makes the evaluation feel thin and easy to challenge. More than 10 makes it hard to get stakeholder agreement on weights before you start. The route helps you consolidate related criteria so the matrix stays manageable while still covering all the dimensions that matter for your specific vendor type.
Share the draft criteria list and ask each stakeholder to distribute 100 points across them according to their priorities. Average the distributions to set the weights. This process reveals disagreements about priorities before the vendor evaluation starts, not during the final recommendation meeting where stakes are higher and positions are more entrenched.
