Audit and Assurance

Expertise

Trusted insights at the intersection of compliance and strategy

As auditors, we bridge the gap between responsiveness and efficiency, technology and human insight, and compliance and long-term goals.

Our partners and senior staff lead every audit with direct guidance and accountability from kickoff to close. With deep experience and industry specialization, we understand the challenges you face and fully customize our approach for maximum relevance and quality.

Our technology takes your audit further. AI-powered software identifies risks in data and documentation to enable targeted sample testing, efficient contract reviews, and augmented technical research. Our secure client portal keeps data flowing and the audit on schedule. From there, we apply our expertise to analyze financial trends, resolve issues promptly, and strengthen business intelligence — all while reducing demands on your team.

From start to finish, you can count on us for transparency, easy access to technical specialists, and no surprises.

Excellence recognized: We’ve been named a Representative Vendor in the 2024 Gartner Market Guide for External Audit Services.

Jerry L. Wright

VP of Business Affairs & CFO, Adrian College

We weren’t looking to make a change. We sent an RFP simply to perform due diligence and benchmark our incumbent audit firm. But Plante Moran blew the socks off our audit committee. We switched because of the people and the firm’s reputation. We have a comfortable, collaborative relationship, and have been very impressed with the team’s subject matter knowledge, higher education accounting experience, and communication. What we value most? The team is always available throughout the year for dialogue and consultation, and their flexibility and industry knowledge provide the expertise we need. We’d rate our overall experience working with Plante Moran as A-plus and wouldn’t hesitate to recommend them.

Brian Mulcahy

Director of Finance, Des Moines International Airport

We’ve worked with Plante Moran for the past three years and appreciate their expertise. The audits are well planned and efficiently completed. The entire team has extensive knowledge of airports, focuses on the key areas of risk, and is very proactive regarding the impact of GASB-related changes. I really like Plante Moran’s use of a secure site to collect audit documentation in a very organized manner. I’d highly recommend Plante Moran to other businesses.

Dave Tallman

Chief Financial Officer, Ross Structural Steel, Inc.

Technical competence and professionalism are a given in public accounting, but what makes Plante Moran unique is its people. They’re so very easy to work with. From the partner who handles our account to the associates who come on-site for our annual review, everyone is pleasant, friendly, and respectful. They understand the other demands of my job in addition to their requests for information. The people from Plante Moran make an annual audit or review as pleasant an experience as it could possibly be.

Gary Houtz

CFO, The Columbus Serum Companies

Plante Moran accountants always provide us with useful and innovative recommendations. They have gone beyond just validating our financial records by suggesting ways to contain our transportation costs and better manage risk. They offered us successful approaches to our complicated tax issues and served as trusted advisors during an ownership change. We have learned to depend on them for expertise to enhance the value of our companies.
