Supplier B
by $0.28 per unit
Defect cost changes the ranking more often than the quoted price does: a 3% defect rate on a $34.00 consequence adds $1.02 per unit. The 5-week lead time gap also costs working capital that appears in no quote.
How the Supplier Quote Comparison Calculator works
Defect rate changes the ranking more often than the quoted price does. A three percent defect rate on a thirty-four pound consequence adds over a pound per unit, more than most price differences between suppliers.

Frequently asked questions
How should I compare supplier quotes?
All-in per unit: goods, freight, duty and the expected cost of defects. Lead time and payment terms then adjust the comparison for working capital.
How do I estimate a defect rate?
From samples, from an inspection report, and from the supplier's own data if they will share it. A supplier who cannot state their defect rate probably does not measure it.
What does a defect actually cost?
A replacement, the shipping both ways, the support interaction, and the review. In consumer ecommerce the review is often the largest of the four.
Does lead time have a cost?
Yes, longer lead times require more safety stock, which ties up capital and storage. A five-week difference is worth real money at any volume.
