How to compare construction supplier quotations
Compare supplier quotations fairly: normalize terms, check exclusions first, convert to a landed figure and score the non-price factors. Includes an editable comparison grid.
To compare supplier quotations fairly, put them on the same footing first: same specification, same units and currency, same delivery terms, same validity, same scope. Only then compare price. Exclusions explain most gaps between a low and a high quote.
Step 1: check the specification matches
Read each quote against your RFQ. Note every line where the offered product differs from what you requested; those lines are alternates, not equivalents, until approved. See writing the RFQ.
Step 2: list exclusions
For each supplier, list what is not included: freight, packaging, insurance, unloading, documents, testing, taxes. For prefab and turnkey offers also read scope exclusions to check in a prefab quote.
Step 3: normalize price
Convert to one currency (state the rate and date), one unit, and a landed basis. The guide to delivered cost has a calculator.
Step 4: score non-price factors
Lead time, payment terms, warranty, documentation quality, communication and references all matter. Fill in the grid below with your own findings. It is a thinking aid; the entries are yours.
Step 5: verify the supplier
Run the due diligence checklist on the finalists. A great quote from an unverifiable entity is a risk, not a saving.
Step 6: negotiate and record
Ask the preferred suppliers to confirm in writing any changes. Record the final scope in the purchase order (checklist).
Warning signs
- Price far below the others with no explanation.
- Refusal to provide datasheets or test reports.
- Pressure to pay in full before any documents are issued.
- Quotes that change terms between versions without a stated reason.
