Audit & Assurance CPAs

Audit and assurance services provide independent verification of an organization's financial statements, offering stakeholders the confidence required for lending, investment, and regulatory compliance. These services range from full audits—the highest level of assurance—to reviews and compilations. While accounting software can generate financial reports, it cannot provide the independent attestation required by external parties. A qualified CPA adds value by performing rigorous analytical procedures, testing internal controls, and ensuring compliance with Generally Accepted Accounting Principles (GAAP) or Other Comprehensive Bases of Accounting (OCBOA). This process identifies material misstatements and operational inefficiencies that automated systems often miss. Beyond mere compliance, an audit acts as a diagnostic tool, providing management with insights into financial health and risk exposure. Engaging a CPA for assurance services ensures that your financial disclosures meet the rigorous standards expected by banks, venture capitalists, and government agencies, ultimately reducing the cost of capital and fostering trust with your stakeholders.

How audit works

Assurance engagements are governed by the American Institute of Certified Public Accountants (AICPA) standards. An audit involves extensive testing and verification, resulting in an opinion on whether statements are free from material misstatement. A review provides limited assurance through inquiry and analytical procedures, while a compilation offers no assurance. Key regulatory triggers include bank loan covenants often requiring annual audited statements, ERISA requirements for employee benefit plans with over 100 participants, and nonprofit grant thresholds often exceeding $750,000 in federal awards under the Single Audit Act. Common mistakes include failing to maintain proper documentation for journal entries or misclassifying debt versus equity. Recent updates, such as changes to lease accounting (ASC 842) and revenue recognition standards (ASC 606), have increased the complexity of financial reporting. Auditors must maintain strict independence, meaning they cannot perform bookkeeping or management functions for the entity they audit. Deadlines vary by contract, but public companies must adhere to SEC filing timelines, while private entities typically align with bank reporting requirements.

Who needs audit

Businesses should evaluate their specific assurance needs based on external requirements rather than internal preference. If you are a startup seeking Series A funding, investors will likely mandate a financial statement audit to validate your burn rate and revenue recognition. Similarly, if your company holds a line of credit exceeding $1 million, your lender will typically require annual audited or reviewed statements as a condition of the loan agreement. Nonprofit organizations receiving significant federal funding must undergo a Single Audit to comply with OMB Uniform Guidance. Conversely, small businesses with minimal debt and no external investors may find that a compilation or a simple tax-basis financial statement is sufficient for internal management. If you are unsure of your requirements, review your loan covenants or grant agreements. Relying on DIY software for these reports is insufficient, as third parties require the signature of an independent, licensed CPA to accept the validity of the financial data.

Pricing

The cost of assurance services is driven by the complexity of the entity, the volume of transactions, and the level of assurance required. Compilations are the most cost-effective, typically ranging from $2,000 to $5,000. Reviews involve more analytical work and generally cost between $5,000 and $15,000. Full audits are the most resource-intensive, with fees ranging from $15,000 to over $50,000 for complex organizations. Factors that increase pricing include decentralized operations, significant inventory counts, complex revenue recognition models, and poor internal record-keeping. Conversely, businesses that provide clean, reconciled trial balances and organized supporting schedules can often keep costs at the lower end of these bands. Always request a detailed engagement letter that outlines the scope of work to avoid unexpected overages during the audit process.
