  5. COGS Decay

Cost Management

COGS Decay

By Herzel Mishel · Founder, Agentis · Last reviewed May 5, 2026

Definition

The gradual divergence between the COGS data used in pricing/checkout systems and actual supplier costs, leading to margin miscalculation.

COGS decay occurs when the cost of goods sold data in your commerce or checkout system becomes stale relative to actual supplier costs. This happens naturally as supplier prices change, raw material costs fluctuate, manufacturing costs shift, or negotiated pricing tiers expire. For merchants who update COGS quarterly or monthly, the gap between system COGS and real COGS can grow to 3–8% within weeks — meaning every profit calculation during that period is wrong. COGS decay is particularly dangerous for subscription commerce where product costs change but billing remains static. Real-time ERP synchronization (e.g., Agentis’s NetSuite integration via Celigo) eliminates COGS decay by pulling live cost data for every checkout evaluation.
