Core offering

Audit One is a CPA firm that provides financial audit, review, and compilation services primarily to non-public entities, including specialized audits for Commercial/Residential Condominium Associations (CIRAs), 401K and employee benefit plans, and not-for-profit organizations. The firm also provides peer review services to other CPA firms, tax preparation and planning, business consulting, and certified QuickBooks ProAdvisor support.

Product overview

Audit One is a CPA firm offering a unified portfolio of audit, accounting, tax, and advisory services rather than a software product platform. The core offering comprises financial statement services at three assurance levels: Financial Audits (highest level with third-party verification), Reviews (moderate assurance through analytical procedures), and Compilations (lowest level representing management statements). Supporting services include specialized 401K/Employee Benefit Plan Audits, Non-Profit Organization Audits, and Peer Review Services for other CPA firms. The firm also provides QuickBooks ProAdvisor consulting services, tax preparation and planning, business consulting, and bookkeeping/payroll services. QuickBooks support covers all Intuit product lines including Enterprise Solutions, Premier industry editions, Online, and Point of Sale. Financial calculators are offered as supplementary online tools. The firm operates from two Illinois locations (Tinley Park and Peotone) serving clients throughout the Greater Chicagoland area and statewide.
