1. Introduction and Objectives
Modern cost accounting extends past the physical walls of the factory to track global supply chain expenditures. This lesson reviews total-cost-of-ownership economics and regulatory risk metrics.
 
2. Total Cost of Ownership (TCO) Framework
When sourcing components from global suppliers, the invoice price represents only a fraction of the total economic cost. Accountants use TCO to capture all related expenditures:
TCO = Invoice Purchase Price + Inbound Freight / Logistics + Import Tariffs + Insurance in Transit + Customs Brokerage Fees + Cost of Incoming Quality Audits + Holding Costs
3. Supply Chain Risk Controls
  • Currency Fluctuation Tracking: Managing foreign exchange risk using hedging instruments (forward contracts) to lock in standard material pricing costs.
  • Dual Sourcing Strategy: Splitting purchases between a low-cost global vendor and a local vendor to balance financial savings with supply chain resilience.
  • Sustainability and ESG Costing: Tracking the environmental footprint of material logistics, including carbon tariffs (e.g., Europe’s CBAM framework) and the costs of compliance with recycling regulations.
