Compare the Complete Supply Scope in Wiper Quotations
Published by QINAI (瑞安市汽耐雨刷制造有限公司).
Two prices are comparable only when they refer to defined items and conditions. Align the component, supplied combination, unit and packaging before interpreting a difference as a saving or a higher cost.
Which quotation fields need to match?
Create a comparison with separate columns for each offer. Mark differences as differences rather than filling missing information with assumptions.
| Comparison point | Question to resolve |
|---|---|
| Item and revision | Is the same defined component being offered? |
| Included parts | Is the offer for a loose item or a complete set? |
| Unit | Does the figure apply per piece, set or pack? |
| Packaging | Are pack contents and labelling requirements equivalent? |
| Requested supply conditions | Which timing, delivery and other conditions are stated? |
How should different units be compared?
Convert units only after the contents are clear. For example, if an illustrative pack contains ten identical sets, its pack price can be divided by ten to express the price per set. That arithmetic still does not establish equivalence if another offer excludes a component or uses a different specification.
Normalize the quantity before comparing the number
Consider an arithmetic example with no real supplier prices: Offer A states 240 currency units for a pack of 20 defined sets, which is 12 per set. Offer B states 11 per body but excludes an adapter included in A. The numbers 12 and 11 do not yet compare equivalent supply. The missing adapter and any other differences must be identified before a conclusion is drawn.
If both offers concern the same defined set, a unit conversion can make the figures readable on the same basis. It still does not resolve differences in revision, packing, delivery scope or other stated conditions. Keep those differences visible beside the calculation rather than hiding them in a single adjusted price.
Separate a technical gap from a commercial choice
An unresolved connection requirement cannot be settled by choosing the lower quote. First establish whether the proposed items address the required combination. After that, the buyer can compare the agreed scope and conditions. This order avoids treating a cheaper but differently defined item as a like-for-like saving.
A proposed optional item should also remain separate from the base supply. If one offer includes spare adapters and another does not, state that distinction instead of assuming the extra pieces are necessary or unnecessary for the customer.
Preserve the assumptions in the comparison
Use a note for every conversion: original unit, contents per unit and calculation. Mark unquoted items as unresolved rather than entering zero. A blank condition and a confirmed exclusion mean different things. The resulting comparison should explain why the offers differ, not merely rank a column of prices.
What should remain outside the price comparison?
Keep unresolved fitment, sample and specification questions visible. A price difference cannot resolve a technical mismatch, and a catalogue image is not a substitute for agreed supply contents. Use the supply-item guide to define the unit, then the volume-order checklist before using a quotation as the basis of an order.
