Derivation Chain

Step 1 USD/KRW exchange rate volatility

Step 2 Import cost management tools

→

Step 3 Exchange rate fluctuation → automatic per-item cost recalculation alerts

Problem

When the USD/KRW exchange rate fluctuates by more than 10 KRW (~$0.0075) in a single day, small manufacturers and distributors importing raw materials and components must manually recalculate costs for hundreds of items. At 5-10 minutes per item, 50 items take 4-8 hours. Delayed recalculation leads to unnoticed margin inversions, causing an average 3-5% in unnecessary losses.

Solution

Users register USD unit prices per imported item, and the system automatically recalculates item-level costs and margin rates in real time when exchange rates fluctuate, instantly flagging margin-risk items. Features: (1) Bulk registration and management of item-level USD prices, (2) Automatic item-level cost change alerts when exchange rate thresholds are reached, (3) Priority sorting of margin-inversion risk items.

Target: Purchasing managers at small import distributors and manufacturers with annual revenue of 3-30 billion KRW (~$2.25M-$22.5M)
