Two quotes, same photo, 18% apart. Here is what is missing.

2026-11-138 min read By Jake Langtao, Beijing Jingkejia Energy Saving Technology Co.

Quotations are sales documents, not cost documents. Each one is written to look attractive against whatever the buyer is likely to compare it with, which means the expensive lines get pushed off the page or folded into a single unit price.

The fix is mechanical: put both quotes into the same template, mark every missing line as missing rather than as zero, and compare landed cost instead of unit price.

The lines that get left out

LineHow it hidesWhy it changes the answer
Trade termFOB vs CIF vs DDPFreight, insurance, duty and clearance responsibility move between parties
PackagingPoly bag vs colour box vs gift boxUnit cost moves, and so does carton volume, which moves freight
CertificationExcluded, or quoted separately laterA one-off four-figure amount that belongs in the first order
ToolingAmortised into unit price, or billed onceChanges first-order cash flow and the true break-even volume
SparesSilentTwo to five percent of order value on most categories
Payment terms30/70 vs 50/50 vs against documentsChanges how much capital you tie up for how long
InspectionWho paysThird-party inspection runs a few hundred dollars per man-day

Normalise, then compare

Build one blank table with those lines, copy both quotations into it, and write not quoted in any empty cell. The discipline matters more than the tool: a missing line is not free, it is unpriced.

A working rule: a gap above fifteen percent is never a cheaper factory. It is a line that one of them did not include. Find the line, then decide whether the difference is worth it.

Landed cost is the only number that matters

Unit price times quantity is the first of nine terms. The full sum is: goods, packaging, tooling, certification amortised over the first order, inland freight to port, main freight, insurance, duty, last-mile delivery, inspection, and the cost of the capital tied up while the goods are in transit. Most buyers stop after the first term, which is exactly why quotes are written that way.

What a good supplier does differently

  • Lists what is not included before you ask.
  • Says which option they would not buy, and why.
  • Offers two configurations rather than one price, so you can see the trade.
  • States lead time in days from a named event, not from received deposit.
  • Answers what they cannot do as clearly as what they can.

Red flags worth walking away from

  1. A unit price with no carton dimensions, quantity per carton, or gross weight.
  2. A lead time that names no number of days.
  3. A bank account whose name does not match the company name on the quotation.
  4. Refusal of a live video call from the production floor.

How to send an enquiry that gets comparable answers

Give every supplier the same five inputs: quantity for the first order, quantity for the expected repeat order, destination city and postcode, the trade term you want quoted, and the target retail price. Then ask all of them the same questions. Suppliers quote to the shape of the enquiry, so an enquiry that leaves room will be filled with whatever is cheapest to say.

Questions we get on this

Is the cheapest quote usually the worst?
Not usually the worst, but almost always the least complete. In this category the cheapest quote is frequently the one with no certification, no spares and the smallest carton on paper.
Should I ask for DDP pricing?
Ask for both FOB and DDP, then compare. DDP is convenient and it hides the duty and the freight inside one number, which is fine as long as you know the split. If a supplier cannot explain the duty rate they are applying, the DDP number is a guess.
How many suppliers should I ask?
Three. Two is not enough to reveal an outlier, and beyond four the marginal information is small compared with the time cost of comparing.
What if the samples differ from each other?
Then the quotations are not comparable, because the product is not the same. Fix the sample specification first, in writing, and re-quote from there.
