How we help

Financial statement audit and review

Single audit

With the increasing emphasis on transparency and accountability for federal funds, certain organizations may need to go beyond the financial statement audit. At Wipfli, our team of dedicated single audit professionals work with you to deliver a smooth single audit process.

Internal audit

Get the most out of your internal audit. When you outsource or co-source your internal audit to Wipfli, you gain professionals who specialize in internal audits and bring a consultive mindset to working with you. We help you develop a strong internal audit plan, identify best practices, note inconsistencies and redundancies, and mitigate risk.
