Total Cost of Acquisition
Definition
The complete cost of acquiring an item from a supplier, including price, logistics, transaction costs, quality costs, and inventory costs, not just the quoted unit price.
In Practice
Total cost of acquisition (TCA) extends landed cost by adding the internal costs a supplier choice creates: ordering and expediting effort, incoming inspection, cost of defects and returns, inventory carrying cost driven by lead time and MOQ, tooling, qualification, and payment-term effects on working capital. It is the procurement-focused cousin of total cost of ownership, which additionally covers use, maintenance, and disposal.
TCA changes sourcing decisions. A supplier with a slightly higher price but shorter lead time, smaller MOQs, and near-zero defects often wins on total cost, because the cheap alternative forces you to hold more inventory, inspect more, and expedite more.
Example: comparing two component suppliers, a buyer finds supplier A is 4 percent cheaper per unit, but its twelve-week lead time and 10,000-unit MOQ add carrying costs, and its 2 percent defect rate adds inspection and rework. Supplier B's total cost per good, delivered unit is 6 percent lower.
