1. Match the specification
Put each supplier offer against the same product brief. Compare materials, dimensions, finish, function, accessories and packaging. Mark differences rather than treating similar product names or photographs as proof of an identical offer.
2. Separate included and additional costs
Record the currency and quantity basis alongside each figure. Ask which charges are included, optional or still unknown.
- Unit price, minimum quantity and price breaks where quoted.
- Samples, customization, tooling and packaging.
- Inspection, testing and agreed coordination fees.
- Freight and destination costs under the stated delivery scope.
3. Compare timing and responsibilities
Record quote validity, sample and production lead times, payment milestones and delivery terms. Clarify what starts the lead time, who supplies required documents and who pays each provider. A quoted estimate should remain distinguishable from a date confirmed for the actual project.
4. Resolve missing details before choosing
List unanswered questions and ask suppliers to confirm assumptions in writing. Decide what requires a sample, document review or specialist assessment. If a material difference remains, compare it explicitly instead of combining unlike offers into a single price ranking.
5. Use a simple comparison record
Illustrative structure only: supplier and quote date → product specification → quantity and unit price → separate charges → timing and terms → exclusions → evidence needed → next decision. This is a suggested working template, not a past project result. Use it to choose which option to investigate, revise or pause.
