Quick answer
The lowest visible number is not automatically the lowest usable quote.
Confirm the exact item and option, then separate product amount, packaging, domestic delivery, service charges, international shipping and duties or taxes. Keep unknown costs marked as unknown.
Confirm the quote identity first
Before comparing amounts, match each reply to the exact product code, color, size or model, quantity and packaging assumption. A broad price list may show a useful range, but that range may describe another option or a different order size.
Rebuild every reply into seven fields
- Item code and variation.
- Quoted quantity and whether the MOQ is met.
- Currency and unit price.
- Product subtotal.
- Packaging and domestic delivery.
- International shipping basis or explicit exclusion.
- Quote date, validity and remaining unknowns.
Compare like with like
| Field | Quote A | Quote B |
|---|---|---|
| Item basis | Code + black + size range | Category name only |
| Quantity | 20 units | 20 units |
| Packaging | Individual bags included | Not stated |
| Domestic delivery | Separate amount | Included, destination unclear |
| Packed weight | Estimate with basis | Unknown |
| Comparison status | Usable with one open question | Needs clarification |
This table does not select a supplier. It shows which quote can support a decision and which one still mixes assumptions.
Leave missing landed costs blank
When freight, duties, taxes or service fees are unknown, leave them blank. Do not subtract an assumed discount, convert currency without recording the rate date or treat a general shipping promise as a price. Keep the product quote request separate from the logistics request.
For example, “4.80 per unit” is still incomplete if the reply does not say which option it covers, whether individual packaging is included or where domestic delivery ends. Record 4.80 as the stated unit amount, then list those three points as open questions instead of building them into an estimated total.
Run one transparent comparison calculation
For each quote, calculate the known subtotal from the quoted quantity and unit amount, then add only the stated packaging and domestic-delivery lines. If you convert currency, record the rate source and date beside the converted figure. Leave an incomplete subtotal incomplete instead of filling freight or taxes with a guess. This often reveals that a cheaper unit amount belongs to a different option, excludes packaging or depends on a larger quantity.
Preserve changes instead of replacing history
If the amount changes after an option, quantity or packaging question, add a new dated version and record the reason. This shows whether the quote changed because the product basis became clearer or because the commercial terms changed.
Pause a quote that cannot be compared fairly
Stop comparing when the item is ambiguous, the quantity basis changes between replies, the currency is missing, included costs cannot be separated or the contact refuses to state what the number covers. A clear quote is more useful than a low number with an unclear basis.
