auditar

To audit — examine a company's accounts, records, or processes for accuracy and compliance: auditar las cuentas de una empresa. Standard business and accounting vocabulary, rarely used outside that professional context.

• Una firma externa audita las cuentas cada año. — An outside firm audits the accounts every year.
• Van a auditar el departamento de finanzas. — They're going to audit the finance department.
• El gobierno auditó el uso de los fondos públicos. — The government audited the use of public funds.

Using auditar loosely for any kind of "checking" or "reviewing" — it specifically implies a formal, often financial or compliance-related examination, not a casual look-over, which is revisar.
