Expense control is the set of rules and checks an organization uses to approve, track, and audit business spending. It can include spending limits, approved merchant or software lists, receipt requirements, and review of unusual or out-of-policy transactions.
In cyber security and finance operations, clear controls help organizations identify unauthorized purchases, reduce misuse of company funds, and manage subscriptions to digital services. For example, a reimbursement program for AI software is easier to govern when it specifies eligible tools, price limits, and required documentation. Payment platforms may provide transaction records and approval features, but organizations still need to define policies and review exceptions.
