How to compare annual supplier pricing offers
Freeze the product list and quantity per SKU, then multiply those quantities by each offer's unit prices and compare the totals against the same baseline. Keep changes in buying mix, currency and delivery costs separate. Cambridge China Bridge can help buyers reconcile factory offers through its own staff in China.
Freeze the basket before requesting annual prices
Choose a reference basket for the unchanged range: either last year's purchased quantities or an agreed annual forecast. Record why you chose it and use exactly the same quantity per SKU for the baseline and every offer. Keep sizes, colours and pack formats on separate rows where their prices differ.
Confirm that the specification and purchasing unit remain unchanged. A carton price cannot be compared with a piece price until the contents are reconciled. Use the supplier quote comparison guide to settle specification and scope differences before applying this annual comparison.
Calculate the cost of the same basket
Keep a row for every product, with its fixed quantity, baseline unit price and unit price under each offer. Multiply the fixed quantity by the relevant unit price to obtain each row's extended cost, then add the rows for each price column. Subtract the baseline basket total from each offer total to show the quoted price movement in money.
To express the movement as a percentage, divide that difference by the baseline basket total and express the result as a percentage. Do not average the percentage changes across products: that gives low-spend products the same influence as high-spend products. Rank complete offers by their fixed-basket totals and review the largest row-level contributions.
Separate price movement from the buying mix
Keep the fixed-basket comparison unchanged when the purchasing forecast changes. Prepare a separate planning view using the revised quantities and each offer's prices. Buying more expensive products can raise total spend and the average price per unit even when every product's unit price stays unchanged.
For a spend reconciliation, first price the reference quantities at baseline prices, then at the selected offer's prices. The difference isolates the price effect on that basket. Next price the revised quantities at the selected offer's prices. The further difference reflects quantity changes, including buying mix; label it as quantity and mix, rather than pure mix, if overall volume also changes.
Keep commercial conditions outside the headline saving
Ask whether annual prices depend on order size, release schedule, payment timing or a volume commitment. Annual demand does not automatically establish eligibility for a price intended for a larger production batch. Obtain prices for the planned order pattern. Keep conditional rebates separate from the unconditional basket total until their conditions are clear.
Use the same comparison currency and exchange-rate assumption throughout. Show freight, setup charges and other cost layers separately so their movement is not described as a factory price change. Apply the same cost boundary to the baseline and offers; the landed-price guide explains the broader cost layers.

Resolve gaps and retain a decision record
A missing product price makes the full-range total incomplete. Ask for a firm price against the frozen basket rather than silently dropping the row or carrying forward its old price. If a specification has changed, obtain a comparable offer or show the affected product separately without claiming a whole-range saving.
Save the basket version, quotation documents, assumptions, exclusions and written clarifications together. Record the selected offer's fixed-basket result alongside the revised purchasing budget and any conditional savings. Use these findings in factory negotiations. Cambridge China Bridge's staff in China can help clarify the factory's pricing basis and unresolved product rows.
Frequently asked questions
Should I use last year's quantities or next year's forecast?
Either can be useful. Choose and label the basket before comparing, then use it for the baseline and every offer. Keep a revised forecast in a separate planning view.
Can I average the price increases across products?
Use fixed quantities to calculate extended costs and compare basket totals. A simple average of product percentage changes ignores how much you spend on each product.
Why has spending risen when unit prices are unchanged?
You may be buying more units or shifting towards expensive products. Reprice the same quantities to test price movement, then show quantity and mix changes separately.
What if an annual offer leaves a product unpriced?
Mark the full-range comparison incomplete and request the missing price. Do not remove the product or substitute its old price while presenting the total as a complete offer.
