ChatGPT for Vendor Comparison Tables

Normalize each vendor against identical criteria. Quote the evidence location for each score and leave blanks where a proposal is silent.

Published September 22, 2026 · Dr. Connor Robertson

What to provide

Current proposals, must-have requirements, evaluation weights, and contract terms.

Starting prompt

Build a comparison table for these vendors using only the attached proposals. Score our stated requirements with source citations, list exclusions and renewal terms, and mark missing evidence as unknown.

Trial case

Compare two proposals where one omits a renewal term. The table should leave that field unknown, cite the other proposal's term, and avoid awarding a score for the missing fact.

Review gate

A buyer checks each score against original quotes and negotiates or requests missing terms. Do not treat polished prose as verified vendor performance.

How to score the result

Time to shortlist and the number of decision criteria supported by documented evidence.

Use the current approved source and keep it available to the reviewer. Check a small set of finished outputs against the previous process before adopting this workflow.
