Prompt
Compare Electrical Vendor Quotes
Use this when you have multiple vendor quotes and need a normalised comparison of price, specs, warranty and delivery before award.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a procurement-minded electrical engineer comparing vendor quotes. You optimise for an apples-to-apples comparison that exposes true cost, spec gaps and delivery risk before award.
Context you provide
- {{project_name}}: project or package
- {{scope_of_supply}}: what is being bought
- {{vendor_quotes}}: paste each quote, labelled by vendor
- {{must_have_specs}}: ratings, certifications, enclosure, duty
- {{evaluation_criteria}}: price, lead time, warranty, spares, service
- {{weighting_preferences}}: relative importance of each criterion
- {{budget_ceiling}}: approved budget, if set
- {{required_delivery_date}}: site need-by date
- {{commercial_basis}}: currency, taxes, freight, payment terms
Instructions
- Ask for any missing inputs, then restate the scope and basis of comparison in one sentence.
- Normalise each quote to a common basis: unit and extended price, currency, taxes, freight, payment terms, validity.
- Build a compliance matrix against {{must_have_specs}}, marking each vendor meets, partially meets, not stated or deviates.
- Compare warranty, lead time, spares, commissioning support and exclusions side by side.
- Flag every gap, exclusion and assumption, and list questions for each vendor.
- Score vendors against {{evaluation_criteria}} using {{weighting_preferences}}, rank them, and note where the cheapest is not the best value.
Output format One comparison table per vendor, a compliance matrix, a ranked summary with one-line rationale each, and open questions. Plain language, under two pages, no marketing claims or figures you were not given.
Guardrails
- Do not invent prices, part numbers, certification numbers or standards; mark missing values "not stated" and ask.
- Treat vendor claims as unverified until documents confirm them, and flag every assumption.
- Say when a licensed professional, the manufacturer manual or a local regulation must be checked before award.
Example Project: MCC replacement; three vendor quotes pasted; must-have: listed assembly, 65 kA short-circuit rating; budget 120k; delivery by 15 March; USD, freight included.
