In 2024, CPA firms are grappling with a critical decision: whether to rely on internal audit teams or engage professional audit support services. This choice has gained urgency considering a pervasive talent shortage in the accounting sector. CPA firms are increasingly finding it difficult to recruit and retain skilled auditors, a situation that directly impacts their ability to manage audit workloads effectively and maintain high standards of audit quality.

This talent gap poses a significant challenge. On one hand, internal audit teams offer familiarity with the company’s processes and culture. However, they often face constraints in scalability and specialized expertise, particularly during peak auditing periods. On the other hand, outsourced audit support services present a solution that can fill these gaps. By leveraging external expertise, firms can access a broader range of skills and knowledge, often at a lower cost than expanding in-house teams.

Outsourced audit support doesn’t just address the issue of talent scarcity; it also offers a strategic advantage. These services provide scalability, allowing firms to handle fluctuating workloads without the overhead of hiring additional permanent staff. Moreover, professional audit support services bring in fresh perspectives and innovative practices, which can enhance the quality and efficiency of audits.

As CPA firms navigate these choices, the decision to go internal or outsource in 2024 hinges on several factors: the need for specialized skills, the desire for operational flexibility, and the imperative to maintain audit quality in a challenging staffing environment. This blog delves into these considerations, helping firms make informed decisions that align with their long-term goals and immediate needs.

Comparing Internal vs. Outsourced Professional Audit Support Services for CPA Firms in 2024 and Beyond

1. Cost Efficiency

Internal Audit: Maintaining an internal audit team involves significant long-term financial commitments, including salaries, benefits, and ongoing training for staff. These expenses can add up, especially for smaller firms where resource allocation needs to be carefully managed. Additionally, internal teams may require investment in specialized audit software and tools, further increasing operational costs.

Outsourced Audit Support: In contrast, outsourcing audit functions can be more cost-effective for CPA firms. This approach eliminates the fixed costs associated with full-time employees, as firms pay only for the services they need when they need them. This can be particularly advantageous during fluctuating workloads, such as seasonal peaks in audit demand. Outsourcing also reduces the need for investment in expensive audit tools and technologies, as these are typically provided by the outsourced service provider.

2. Access to Specialized Expertise

Internal Audit: While internal auditors are well-versed in the company’s specific operations and culture, they may lack certain specialized skills or knowledge, particularly in niche or rapidly evolving areas of accounting and auditing. Keeping internal teams up-to-date with the latest auditing standards and practices can require significant ongoing training and professional development.

Outsourced Audit Support: Outsourcing offers CPA firms access to a pool of professionals with a diverse range of expertise and specialized skills. This is especially beneficial for complex audit scenarios that require specific knowledge or for staying abreast of changes in accounting standards and practices. Outsourced providers often have teams that specialize in different areas of auditing, providing a breadth and depth of expertise that might be challenging for internal teams to match.

3. Scalability and Flexibility

Internal Audit: Scaling an internal audit team to match fluctuating demand can be a significant challenge. During peak audit seasons, internal teams may find themselves overstretched, leading to increased stress and potential for error. Conversely, during slower periods, the firm may find it has excess audit capacity, leading to inefficiencies.

Outsourced Audit Support: Outsourced professional audit support services offer CPA firms the flexibility to scale their audit capabilities up or down as needed. This adaptability is crucial in managing workloads effectively and maintaining high standards of audit quality, regardless of the ebb and flow of demand. Additionally, outsourcing allows firms to respond quickly to unexpected increases in audit demand without the need for long-term commitments to additional staff.

4. Quality and Innovation

Internal Audit: Internal audit teams, being deeply integrated within the firm, offer a consistent level of quality and a deep understanding of internal processes and controls. However, they may have limited exposure to varied auditing methodologies and innovative practices used in different industries or firms.

Outsourced Audit Support: External audit providers often bring fresh perspectives and innovative approaches to the audit process. They are exposed to a wide range of auditing environments and practices, allowing them to introduce new ideas and methodologies that can improve the audit process’s efficiency and effectiveness. This exposure to diverse practices not only enhances the quality of the audit but can also provide insights into best practices that can be adopted by the firm.

5. Risk Management

Internal Audit: An internal audit team has the advantage of a deep understanding of the company’s unique risks, culture, and operations. This allows them to tailor their risk management and audit processes closely to the specific needs and nuances of the firm, potentially leading to more effective identification and mitigation of risks.

Outsourced Audit Support: Professional audit support services bring with them a wealth of experience in managing a variety of risk profiles across different industries and sectors. They apply rigorous, industry-standard risk assessment methodologies that can uncover risks that may not be apparent from within the organization. Their external perspective can provide a more objective view of the firm’s risk landscape, potentially identifying blind spots overlooked by internal teams.

6. Regulatory Compliance

Internal Audit: Internal teams must constantly update their knowledge and skills to stay compliant with evolving regulatory requirements. This necessitates ongoing training and development, which can be both time-consuming and costly. The responsibility to keep abreast of changes in laws and standards lies entirely with the firm.

Outsourced Audit Support: One of the key advantages of outsourced audit services is their commitment to staying current with the latest compliance standards and regulatory changes. This relieves the CPA firm of the burden of constantly training and updating its internal teams on these changes. Outsourced providers typically invest heavily in ensuring their staff is well-versed in current compliance requirements, which can provide a significant advantage in terms of reducing the firm’s compliance risk.

7. Operational Focus

Internal Audit: Running an internal audit function requires CPA firms to divide their focus between their core accounting services and the demands of conducting thorough audits. This can stretch resources thin, particularly for smaller firms, and can lead to conflicts in resource allocation between audit and other business areas.

Outsourced Audit Support: Outsourcing the audit function allows CPA firms to concentrate more on their core business activities, such as client relationship management, strategic planning, and business development. With audits being handled by dedicated external professionals, the firm’s management and staff can focus on areas that directly contribute to the firm’s growth and profitability while still ensuring high-quality audit functions are performed.


The decision between internal audits and leveraging outsourced professional audit support services is a pivotal one for CPA firms in 2024 and beyond. Each option presents unique benefits and challenges, and the right choice depends on the specific needs and circumstances of the firm.

Internal audits offer deep integration and familiarity with the firm’s processes, yet they may lack the scalability and specialized expertise available through outsourced services. On the other hand, professional audit support services provide flexibility, a wide range of expertise, and innovative auditing practices, all of which are essential in today’s dynamic accounting environment. These services not only help in managing fluctuating workloads but also bring fresh perspectives and methodologies to the auditing process. Moreover, the cost-effectiveness and regulatory compliance support provided by outsourced services can be particularly beneficial for firms navigating the complex and ever-changing landscape of accounting standards and practices.

Ultimately, the goal is to ensure that your firm maintains the highest standards of audit quality and efficiency, regardless of the chosen approach. As the accounting industry continues to evolve, staying informed and adaptable will be key to success.
