Enterprises cannot afford to overlook the importance of financial integrity and transparency as competition intensifies amid stricter regulations. It has become a cornerstone for sustainable success. Regular audits help ensure your business remains compliant, efficient, and trustworthy, whether you’re a growing startup or an established multinational. However, one common question many companies face is: what’s the real difference between an external audit and an internal audit?
