The lowest quoted unit price is not necessarily the lowest-cost offer.
Two suppliers may quote the “same” product while using different materials, tolerances, packaging, testing, Incoterms, tooling assumptions, or payment conditions. A fair comparison begins by making every quotation answer the same question.
1. Standardize the RFQ before comparing prices
Send every supplier the same written request for quotation. Include:
- Drawings, dimensions, materials, grades, and tolerances
- Required certifications or testing
- Target order quantity and annual volume
- Packaging and labeling requirements
- Delivery destination and preferred Incoterm
- Sample, tooling, and customization requirements
- Expected lead time
If suppliers quote different specifications, the comparison is not meaningful.
2. Compare the complete commercial structure
| Field | Questions to ask |
|---|---|
| Unit price | For which quantity, specification, currency, and validity period? |
| MOQ | Per model, color, size, material, or shipment? |
| Tooling | Who owns it, how long does it last, and is maintenance included? |
| Samples | Are sample, courier, and revision costs included? |
| Packaging | Standard export carton or custom retail packaging? |
| Testing | Existing report, new test, batch test, or no test? |
| Lead time | From deposit, artwork approval, sample approval, or material arrival? |
| Payment | Deposit percentage, balance trigger, bank charges, and currency risk? |
| Incoterm | EXW, FOB, CIF, DDP, and which named place or port? |
| Warranty | What defects are covered and what remedy is offered? |
3. Normalize the Incoterm
Do not compare an EXW price directly with FOB or DDP. Convert offers to a common commercial basis. At minimum, estimate:
- Pickup from factory
- Export handling
- Freight
- Insurance
- Import duty and taxes
- Destination handling
- Final delivery
4. Calculate the cost of quality risk
A cheaper quotation can become expensive when it increases:
- Defect rates
- Inspection frequency
- Customer returns
- Production delays
- Rework or replacement shipments
- Certification exposure
Include a risk allowance when evidence is weak or when the supplier has not yet passed sample and production validation.
5. Score non-price factors
A simple weighted score prevents price from dominating the decision.
| Factor | Example weight |
|---|---|
| Specification compliance | 25% |
| Quality evidence | 20% |
| Total commercial cost | 20% |
| Lead time and capacity | 15% |
| Communication and responsiveness | 10% |
| Payment and contract terms | 10% |
Adjust the weights to match your product and risk profile.
6. Compare samples under the same conditions
Approve samples against a written checklist, not general appearance. Record:
- Dimensions and tolerances
- Material or component verification
- Function and performance
- Color and finish
- Packaging
- Labelling and documentation
7. Watch for quotation traps
- Missing Incoterm or named port
- Price based on a lower-grade material than requested
- Tooling cost excluded from the headline price
- MOQ that changes after sample approval
- Lead time that excludes material procurement
- “Certification available” without a matching product report
- Packaging not suitable for international transport
A practical quotation-comparison process
- Issue one standardized RFQ.
- Reject incomplete quotations or request clarification.
- Normalize specifications and Incoterms.
- Add tooling, sample, testing, packaging, and logistics costs.
- Score quality, lead time, communication, and payment risk.
- Validate shortlisted suppliers with samples.
- Negotiate only after identifying the real cost drivers.
Bottom line
The best quotation is the offer that delivers the required product at the lowest controlled total cost—not the lowest number in the unit-price column.
