How to compare supplier quotes without comparing the wrong numbers

Most quote comparisons start with the total and end with the lowest number. That is also how teams accidentally award the most expensive supplier. This checklist normalizes the inputs before you decide.

1. Confirm the same scope

Two quotes can both say “rigid box, 10,000 pcs” and still cover different work: printing plates, lamination, tooling, samples, export cartons, and packaging. List every deliverable and mark each quote as included, excluded, unclear, or not mentioned.

A missing line item is not a lower price. It is an unknown that will come back as a change order, a separate invoice, or a delay.

2. Normalize the commercial terms

Term	What to capture	Why it changes the comparison
Incoterms	EXW, FOB, CIF, CFR, DDP, DAP	Determines who pays freight, insurance, duty, and clearance.
Payment terms	Deposit %, balance timing, Net 30/60	A 50% deposit ties up cash; Net 60 has a financing benefit.
MOQ	Minimum order quantity	A lower unit price at a higher MOQ may not fit your demand.
Lead time	Days or weeks from PO	Longer lead time means more safety stock and more risk.
Validity	Quote expiration date	An expired quote is not a decision you can make.
Warranty	Length and coverage	Short or missing warranty shifts future cost to you.

3. Compare landed cost, not unit price

Landed cost is the number that matters: product subtotal, one-time charges, freight, duty, packaging, and the financing cost of the payment terms. If you want the full formula, read landed cost for supplier quotes.

4. Add a risk allowance

Two quotes can have the same landed cost but very different risk. A quote that excludes duty, has no warranty, and expires next week is not equivalent to a DDP quote with a 24-month warranty. A simple risk-adjusted total is:

Risk signal	Suggested allowance
Missing freight or duty	+10–20% of landed cost
Missing warranty	+3–5%
Lead time above 45 days	+3–8%
Quote expires within 14 days	+2–5%
Unclear or contradictory terms	+2–10%

These are heuristics, not accounting rules. The point is to make risk visible in the same unit as price.

5. Ask the same questions of every supplier

Is freight included? If not, what is the delivered cost to our address?
Which Incoterms 2020 term applies, and what is the named place?
Is duty, customs clearance, and import tax included?
What is the MOQ, and what is the price at our target quantity?
What is the confirmed lead time from PO to delivery?
What warranty applies, and what does it cover?
How long is the quote valid?
Are tooling, sampling, plates, packaging, and testing one-time or recurring?

6. Keep the evidence

For every number in your comparison, keep the source page and snippet. When a stakeholder asks “why not the cheapest quote?”, you need to show the missing scope, not just assert that one supplier is better.
