If you ask three factories for "their best price" without giving them the same quote pack, you usually get three non-comparable answers.

Before comparing suppliers, send each one the same minimum pack:

• product spec/revision, materials, tolerances, packaging, and labeling
• target order quantity plus expected reorder quantity
• required MOQ tiers and price breaks
• sample, tooling, mold, artwork, setup, and test costs
• units per carton, master carton size, gross/net weight, and pallet/loading assumptions
• Incoterm plus named place, not just "FOB" or "DDP"
• freight scope: pickup, export docs, origin charges, main freight, destination fees, duty/tax, final delivery
• origin country, HS code if known, and any certification/testing evidence needed for the market
• lead time, quote validity date, payment terms, defect/remedy terms, and excluded items

Then compare the deal on the same basis. A lower unit price is not better if it hides freight, forces a bad MOQ, excludes testing, or quotes a different spec.

Disclosure: I work on GoodsCommand, buyer-side software for supplier quote comparison. No link; this is the checklist I would want buyers to use before any tool or spreadsheet.

When you get 3+ RFQ responses, what fields do you refuse to leave vague before you compare them?

The checklist I see break decisions most often: sellable unit/basis, spec revision, MOQ/tier, Incoterm + named place, freight scope, tooling/sample charges, payment terms, lead time, validity date, origin/HS basis, quality/compliance docs, and explicit exceptions.

Curious where procurement teams draw the line between "good enough to shortlist" and "not decision-ready." Disclosure: I work on supplier/quote process tooling; no product link here.

A common supplier-selection mistake happens before the math: each supplier has priced a different scope.

A simple way to expose that is an assumptions register. Give every important field one row and track these columns:

• Supplier A / B / C value
• status: confirmed, buyer-entered, estimated, missing or contradictory
• evidence: quote page, drawing, email or other source
• owner and due date for clarification
• cost, schedule or risk impact

At minimum, include:

• exact product specification/revision and sellable unit
• order quantity, MOQ and price tier
• currency, price validity and payment schedule
• retail packaging, carton and pallet assumptions
• samples, tooling, inspection and other one-time costs
• lead-time basis: deposit, approved sample, materials received or another trigger
• Incoterm and named place
• origin and supplier-provided HS code
• freight, insurance, duty and additional tariff assumptions
• certifications, test reports, warranty and defect remedy

Three rules keep the comparison honest:

1. Never treat a blank field as zero.
2. Normalize quantity, unit, packaging and Incoterm before ranking price.
3. Separate confirmed facts from estimates and send one consolidated clarification list before awarding the order.

Only rank suppliers once the commercially important rows are decision-ready. Otherwise the lowest total may simply be the quote with the most omissions.
