Plante Moran’s Enterprise Risk Services (ERS) team is comprised of experienced internal audit professionals, many of who hold advanced accounting and finance degrees. We have experience managing Sarbanes-Oxley compliance efforts and leading internal control assessments and reviews in nearly every industry across the country and around the world.

Most of our ERS team members carry professional certifications, including Certified Internal Auditor (CIA), Certified Internal Controls Auditor (CICA), Certified Public Accountant (CPA), Certified Information Systems Auditor (CISA), Certified Fraud Examiner (CFE), Certified Information Technology Professional (CITP), Certified Information Security Manager (CISM), and Certified Information Systems Security Professional (CISSP).

U.S. and multinational companies engage Plante Moran’s Enterprise Risk Services (ERS) team for internal audits and SOX compliance work. We provide a seamless response by collaborating with professional service firms in 72 countries. 

Internal Audit Methodology

Our internal audit methodology is designed to provide in-depth, fact-based results directed towards improving your internal control environment concurrent with maximizing operational efficiency and effectiveness. Each engagement includes the appropriate planning, execution, and reporting along with professional standards-based work papers and supporting documentation. Our seven-step process includes:

  • Risk assessment and planning
  • Project planning and organization
  • Pre-audit meetings and assessments
  • Audit program development
  • Fieldwork activities
  • Periodic status and update meetings
  • Issue reports


Internal Audit Service Offerings

Plante Moran’s ERS team can assist anywhere on the internal audit service spectrum. We can provide you with full capacity internal audit services or simply help out where needed for as long as necessary. We serve clients by providing full outsourcing, cosourcing, and ad hoc staffing needs.

Regardless of the model, we commit to making our methodology and technology available to ensure the very best service. Our ERS team has experience assisting clients within the following environments:

  • Operational reviews for efficiency and effectiveness
  • Internal control review, testing, reporting, and remediation
  • Outsourcing/cosourcing, engagement staffing, project assistance, special projects
  • Mega-project reviews, strategic planning, and support

In recent years, organizations have focused on meeting compliance requirements imposed by the Sarbanes-Oxley Act, often foregoing operational audits for efficiency and effectiveness. Although the focus may have changed, the risk environment in which you operate has not. Don’t be lulled into a false sense of comfort. Your controls over financial reporting may be operating effectively, but don’t forget the rest of your operations.

Our ERS staff members are experienced in providing operational audit reviews for efficiency and effectiveness regardless of the industry. If you are experiencing unexplained variances, frequent write-offs, losses due to misappropriations, or you simply question the effectiveness of certain processes, we are equipped to help.

“Our transition to Plante & Moran was remarkably smooth. We were impressed with the experience level and knowledge of everyone that worked on our audit. The communication and planning were exceptional, meeting all of our expectations, requirements, and deadlines.”
