How to compare wholesale supplier quotations line by line

1. The short answer

Compare supplier quotations in this order:

1. exact product specification and version;
2. sellable unit, pack size and quantity;
3. currency, price basis and validity date;
4. Incoterm 2020 and precise named place;
5. packaging, artwork, tooling, samples and testing;
6. payment milestones and cash exposure;
7. inspection plan, defect process and evidence;
8. freight, customs, duty, delivery and other landed-cost inputs;
9. supplier capacity, communication and change-control risk; and
10. the decision, owner and next negotiation question.

Do not fill a missing number with optimism. Use unknown, assign an owner and show how the decision changes if the input moves.

2. 1. Capture the quote before you interpret it

Save the original PDF, spreadsheet, email or message. Record the date, supplier entity and the person who issued it. Then create a normalised header.

If the quote does not state a field, leave it blank and mark it as an information gap. A blank field is safer than silently treating an exclusion as included.

The supplier-vetting guide explains why the legal entity, contact authority and payment destination should agree before you make the preferred quote your purchase decision.

3. 2. Normalize the product and the sellable unit

Do not compare “unit price” until you know what one unit means.

Check:

• product model, variant and revision;
• materials, dimensions, tolerances, finish and function;
• accessories, batteries, cables or inserts;
• unit, inner pack, case pack and master carton;
• branded, unbranded or private-label artwork;
• packaging and labelling requirements;
• sample, tooling or setup assumptions; and
• whether the quote covers the same production method.

Convert every offer to the same sellable unit. If Supplier A quotes one piece and Supplier B quotes a carton of 24, calculate both on one piece and preserve the case-pack consequences separately.

The quote-ready specification guide gives you the source document to attach to each quotation. If the supplier quotes a different specification, do not “adjust” the price and pretend the offers are identical. Ask for a revised quote or show the difference as a decision risk.

4. 3. Normalize the Incoterm and named place

An Incoterm is not a delivery promise in isolation. It sets a defined set of seller and buyer tasks, costs and risk points within the sales contract. The ICC’s Incoterms rules page identifies Incoterms 2020 as the current version and explains that the rules clarify tasks, costs and risks for delivery.

Write the term in full:

FCA Supplier warehouse, Rotterdam, Netherlands, Incoterms 2020

Do not write only FCA, DAP Europe or FOB China.

Capture:

• rule and version;
• named place or point;
• who loads, collects or hands over the goods;
• who contracts the main carriage;
• who handles export formalities;
• who handles import formalities;
• who bears duty and tax exposure under the agreed route;
• where risk transfers; and
• what the quote does not include.

For a buyer, the named place is a cost and control input. FCA at the supplier premises is not the same operational handoff as FCA at a named terminal. DAP at a warehouse is not the same as DAP at a port. The ICC rule text should be read with the actual place written into your contract.

Quote terms and customs treatment are separate questions. Send the normalised term to the landed-cost model and your customs or tax reviewer where required.

5. 4. Add packaging, tooling, samples and testing

Suppliers often price the product first and the supporting work later. Bring those items into the same comparison.

Use a separate column for included, excluded, conditional and unknown. “Free packaging” is not a complete commercial term if the supplier has not specified the material, print, dimensions or quantity.

If a cost is a one-time setup amount, allocate it transparently for the decision. For example, a €500 mould spread across 5,000 units is €0.10 per unit for that order. Show the total cash amount as well, because a small unit allocation can still create a large upfront commitment.

6. 5. Compare payment terms as a cost and control

A quote with a lower unit price can require more cash before you have evidence that production is ready.

Record:

• deposit percentage and amount;
• progress-payment triggers;
• balance timing;
• inspection timing;
• payment method and fees;
• currency and conversion assumption;
• whether tooling is paid separately;
• what happens if production is delayed; and
• who can approve a shipment release.

The payment-terms guide uses a payment-exposure map to connect each milestone to evidence and buyer control. Bring its output into the quote comparison. Do not call a 30% deposit “standard” or “safe” without knowing the order, supplier, recoverability and evidence.

7. 6. Put quality and execution risk beside price

Quality risk is not a vague feeling. Record the missing evidence and the next check.

Score operational risk separately from the commercial price. A supplier can be the best quote and still need a trial order, sample revision or inspection before you give it the full volume.

8. 7. Convert the comparison into a landed-cost input

O1 should not become a second customs calculator. It should give L1 a clean input pack.

Send these fields to the landed-cost model:

• sellable unit and quantity;
• currency and quote date;
• product price;
• packaging, tooling, sample, testing and inspection costs;
• Incoterm, version and named place;
• origin and destination;
• freight and insurance assumptions;
• customs classification and origin evidence, if already known;
• clearance, delivery, storage and finance assumptions; and
• taxes or duties that need specialist confirmation.

If an input is not known, create a base case and downside case. Do not present an illustrative duty number as a current rate for an unspecified product. L1 owns the verified product, route and date calculation.

9. 8. Worked comparison of three offers

The following figures are invented to show the method. They are not market rates, tax advice or a recommendation. Assume 5,000 identical units, the same product specification and an illustrative import duty input of €0.70 per unit. Recoverable import VAT is excluded from this comparison.

Supplier A has the lowest headline unit price. Supplier C has the lowest illustrated purchase-to-warehouse cost because its quote includes more of the route. That does not automatically make C the right choice.

Ask the next questions:

• Is the DAP named place precise enough?
• Who handles import formalities and who pays duty?
• Are unloading and destination charges included under the carriage contract?
• Does Supplier C provide the same packaging, inspection evidence and production control?
• Does Supplier A give you better control over the carrier or timing?
• Are any of the included transport costs conditional on a minimum shipment or route?

The table makes the assumptions visible. It does not remove the need to verify them.

10. 9. Score the commercial decision separately

Use a weighted score only after the inputs are normalised. Keep a note beside every score.

The weights are yours to set. They are not a universal supplier-ranking formula. The purpose is to make the trade-off visible and give the preferred supplier a clear negotiation agenda.

11. 10. Turn the table into negotiation

Negotiate the missing input before demanding a lower price.

Useful questions include:

• Can you quote the same specification with the same retail and transport packaging?
• Can you separate product, tooling, testing and inspection costs?
• What exact place does the Incoterm name, and which version is being used?
• What is included in the DAP or FCA route, and what is conditional?
• Can the supplier offer a lower quantity by reducing variants or delaying packaging customisation?
• Can the payment milestone move after an agreed inspection report?
• What written process applies if a component, factory or packaging specification changes?
• Can the supplier confirm the production window and the evidence owner?

The MOQ negotiation guide helps you choose a trade rather than simply asking for a smaller number.

12. The reusable worksheet

Keep these columns in the spreadsheet:

Add a not proof of note beside important checks:

• a low unit price is not proof of low landed cost;
• an Incoterm is not proof that customs or tax is handled correctly;
• a supplier declaration is not proof that every model or batch matches;
• an inspection plan is not proof that an inspection occurred; and
• a complete quote is not proof that the supplier will execute it without a change.

13. Final operating rule

Compare offers only after you have made them comparable.

Freeze the specification, convert the unit, write the Incoterm and place in full, add every supporting cost, map payment exposure, record quality evidence and send the result into the landed-cost model. Then decide which unanswered question matters most.

The winning supplier is not always the one with the lowest price. It is the one whose offer you can explain, verify and control.

Scope and source note

This draft was checked on 14 August 2026. The Incoterms references use the ICC Incoterms rules page, the ICC Incoterms 2020 rule text for any mode and the ICC Incoterms 2020 sea and inland-waterway rules. The worked figures are illustrative and must be replaced with product, route and date-specific inputs before a purchase decision.

This page remains a private review draft until the Trade and Landed Cost Desk confirms the worksheet, Incoterm wording, quote examples and handoff to L1. It is commercial planning guidance, not legal, customs, tax or financial advice.
