The lowest number on a quotation is rarely the same as the lowest project cost. A defensible comparison exposes scope gaps, converts commercial terms to a common basis and records the trade-offs that matter after the purchase order is signed.
Normalize the scope first
Build a line-by-line compliance matrix from the original brief. Mark each requirement compliant, conditional, alternative or excluded, and reference the exact page of the bid. Confirm quantities, accessories, consumables, documentation and services. This exercise often explains large price differences before negotiation begins. It also protects the project from selecting an apparently complete offer that depends on unpriced options.
Convert every offer to one cost basis
Restate offers in one currency, Incoterm and delivery point. Add estimated freight, insurance, duties, local handling, installation, training, commissioning, spares and foreseeable operating consumables. Keep estimates identified as estimates rather than silently changing a vendor price. When payment timing differs, show the cash-flow effect separately. The result is a transparent landed-cost view that procurement and finance can both audit.
Score delivery and execution risk
Assess manufacturing lead time, drawing approval, sample requirements, production capacity, packaging, site constraints and the supplier’s response plan for defects or delays. A simple weighted scorecard helps, but weights must reflect the project: schedule may dominate a shutdown spare, while lifecycle service may dominate medical equipment. Add a confidence note where evidence is weak; numerical scores should not create false certainty.
Document the recommendation
Write a short recommendation explaining the preferred offer, the next-best alternative and the conditions that must be resolved before award. List clarifications, agreed deviations and remaining risks. Keep the commercial comparison, technical evaluation and approval record together. This makes the award easier to defend and gives contract administrators a reliable baseline when delivery starts.
Project checklist
- All offers answer the same scope matrix
- Currency and delivery terms are normalized
- Options and exclusions are priced separately
- Schedule and after-sales risk are scored
- Award conditions are recorded before signature
Discuss a defined project requirement
Share the destination, scope and timing so the request can be directed to the relevant specialist company.
