The quick answer
Compare the same product, specification, net weight and named delivery point, then check packing, transport, documents and payment. A lower price per ton does not necessarily mean a lower usable cost.
Align specifications before comparing prices
Begin with a comparison table, not the cheapest figure: commodity, variety, size, format, defect tolerances and net pack weight. Mark each supplier’s response confirmed, omitted or needing clarification. For industrial applications add the sample trial and usable yield. Whole strawberries and pieces are not equivalent simply because they share an ingredient name; juice and retail specifications may also differ. Once the specification is aligned, a price difference becomes interpretable. Before then it may be the price of a different product altogether.
Use net weight and one pricing unit
Establish whether pricing is per kilogram, metric ton or carton and whether the weight is net or gross. A carton containing ten net kilograms means one hundred cartons equal one net metric ton; cartons and pallets are not produce weight. Calculate price per kilogram by dividing carton price by its net contents. This arithmetic example does not establish an actual pack weight. Where formats differ, use the figures written in the quotation and check packing tolerances and how any discrepancy will be settled.
Connect the price to a named delivery point
Shipping included needs detail: to which named place, by which route, and with which exclusions? Ask about inland transport, packing, documentation, insurance and destination charges according to the agreement. Where a trade term is used, have a specialist review its version, named place and allocation of obligations; do not infer scope from the abbreviation alone. Put unknown charges in a separate column rather than treating them as zero. An offer containing unpriced items cannot be fairly compared with one that identifies every obligation.
Consider usable cost as well as purchase cost
For a factory, waste, handling time and pack emptying can change the effective ingredient cost. If a batch costs one hundred currency units and yields eighty usable kilograms, usable kilogram cost is one hundred divided by eighty. This is an internal comparison method, not a prediction of loss for any commodity. Use measured trial results instead of an attractive assumed yield. For retail, assess size, presentation and sorting costs using your own data. Purchase price alone cannot resolve differences in workflow or storage capability.
Compare commitments and uncertainty alongside numbers
Review quotation validity, dispatch timing, inventory confirmation, lot-change handling and payment conditions. Record the available evidence and person responsible for each next step. Ask how delays are notified, claims documented and inspection periods agreed. Then write a clear reason for the decision: the specification fits, costs are understood and the trial worked. If a material item remains unknown, clarify it before committing rather than turn it into an assumption. A useful comparison table makes uncertainty visible so it can be resolved.
