$12,000 purchasing saving.
$3,200 annual total-cost saving.
$62,000 more working capital required.
Same supplier decision.
Consider an NZ importer purchasing 12,000 units annually.
Supplier A charges $10 per unit. Supplier B offers $9, but requires larger orders, longer lead times and payment before shipment.
In this illustrative comparison, once freight, inventory, quality and financing costs are included, the $12,000 purchasing saving reduces to approximately $3,200.
Supplier B is still the lower annual-cost option.
But the business needs around $62,000 more working capital to support it.
Would you commit an additional $62,000 in working capital to achieve a $3,200 annual saving?
