AICPA Peer Review St Louis (MO) | CPA Firm Peer Review

AICPA Peer Review – St. Louis (MO)

St. Louis and Missouri CPA firms are required to undergo a firm peer review every three years – a requirement mandated by both the American Institute of Certified Public Accountants (AICPA) and state licensing agencies.

A peer review is an independent examination of a firm’s accounting and auditing practices by another CPA firm. The purpose is to build client confidence, enhance professional development, identify and mitigate risks, and to satisfy compliance requirements. The reviewer examines ethical requirements, human resources, client acceptance procedures and engagement performance and monitoring. Since the results of peer reviews are publicly available, working with an experienced provider who will carefully examine operations is critical.

About the St. Louis Business Community

City of St Louis logoThe St. Louis business community is a diverse and resilient hub that blends legacy industries with growing innovation sectors, positioning the city as a major economic driver in the Midwest. Historically rooted in manufacturing and trade along the Mississippi River, St. Louis has evolved into a center for healthcare, financial services, biotechnology, and advanced manufacturing. Major corporations such as Emerson Electric, Centene, Edward Jones, and Ameren maintain a strong presence, while health institutions like BJC HealthCare and Washington University School of Medicine reinforce the city’s standing as a healthcare and research leader. The biotech corridor around Cortex Innovation Community has gained national attention, drawing startups and venture capital while fostering partnerships between universities and private industry.

Agribusiness also plays a central role, with Bayer Crop Science headquartered in the region and companies such as Purina and Monsanto shaping innovation in seed science, food production, and animal health. Logistics and transportation are strengthened by the city’s central location, river access, and strong rail infrastructure, making St. Louis a strategic hub for distribution and supply chain operations. At the same time, the financial services sector has flourished, with Stifel Financial and other investment firms anchoring downtown, complemented by a growing tech ecosystem that attracts entrepreneurs and accelerators.
