Which of the following is NOT a type of spend category usage?

The concept of spend category usage involves various classifications that represent how an organization spends its money. In this context, supplier audit is not recognized as a spending category usage.

Spend categories typically include types that directly relate to how organizations procure goods and services. For example, ad hoc payments refer to spontaneous or one-time payments made for specific purchases that may not fall under regular procurement processes. Expense categories generally pertain to employee spending that occurs within the organization, such as travel, meals, or other reimbursable costs, and procurement directly relates to the process of acquiring goods or services.

Supplier audit, however, does not fit within these classifications. It is a process aimed at reviewing and evaluating suppliers for performance and compliance rather than a category of spend. This distinction clarifies why supplier audit is not a type of spend category usage.
