When this workflow helps
If you are searching for how to use ChatGPT to compare small business vendors, first decide who owns the result and where it will be used. A good draft saves preparation time only when the underlying facts are available and a person can inspect the output. This guide is for that specific deliverable; the ChatGPT Workflows for Small Business hub collects adjacent tasks.
Gather the source material
Current proposals, must-have requirements, evaluation weights, and contract terms. Use the current approved version. Remove details that the team is not permitted to place in an AI tool, or use a workspace and access controls approved for that data. Keep a link to the original material so reviewers can trace the result.
Build the first draft
Normalize each vendor against identical criteria. Quote the evidence location for each score and leave blanks where a proposal is silent. Start on one representative example, not the entire backlog. If a required fact is missing, ask for a marked gap rather than a plausible completion. Save the output as a draft with the source date and an assigned reviewer.
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.
Replace the example input with your own approved documents and specify the output format your team actually uses. Ask for a short list of uncertainties alongside the draft. Keep the source and output together during review so a polished sentence does not hide a missing fact.
Review before use
A buyer checks each score against original quotes and negotiates or requests missing terms. Do not treat polished prose as verified vendor performance. Check names, dates, figures, citations, and commitments against the originals. If a consequential decision or external communication is involved, the designated human owner makes the final call and follows the normal approval path.
Measure whether it worked
Track Time to shortlist and the number of decision criteria supported by documented evidence. Compare a small set of completed examples with the previous process. Record corrections, not only time saved; a faster draft that creates rework is not an improvement. Revise the prompt when the same error appears twice.
