Cost center
A cost center is an organizational unit that incurs costs but does not directly generate revenue. In procurement, cost centers allocate purchasing expenses to the correct budget owners and track spending by organizational responsibility.
Examples
Purchase allocation: When ordering lab supplies used by multiple departments, the system splits the purchase order cost across three cost centers based on proportional usage.
Budget control: Each cost center has an annual procurement budget. The system checks available budget before approving requisitions, preventing overspending by any single department.
Spend reporting: Monthly spend analysis by cost center reveals that R&D accounts for 40% of indirect purchases despite 15% of headcount, prompting a consumption review.
Definition
Cost centers provide the organizational structure for financial accountability in procurement. Every purchase must be charged to a cost center, creating a link between spending and the responsible business unit.
In procurement operations, cost center structures determine approval routing, budget checks, and reporting hierarchies. A requisition's cost center assignment determines who approves it and which budget is checked.
For analytics, cost center data enables spending pattern analysis by organizational unit and identification of consolidation opportunities when multiple cost centers buy similar items independently.
The challenge is that cost center structures reflect organizational hierarchy rather than purchasing logic. A strategic category may be split across dozens of cost centers, making total spend visibility difficult without cross-cutting analysis.
