Factors that affect the cost of audit support services
There are numerous ways to influence outsourcing audit support pricing through several factors, including size, industry and financial complexity of the company being audited. Larger, more complex, high-risk businesses typically incur higher audit support costs due to the additional time and oversight required compared to smaller companies or those in less complex or lower-risk environments. In addition, companies with strong internal controls that are prepared for an audit typically incur lower costs than those with weak internal controls and require a longer time to correct errors.
Factors Related to Your Company
Size and Complexity of the business model
The size and complexity of an entity are some of the biggest determinants in the pricing of audit outsourcing services. Companies with a higher volume of financial transactions and multiple subsidiary entities across many geographic locations will typically require more extensive audit procedures due to this volume of transactional activity.
To meet the expanded scope of services resulting from this increased volume, additional hours and resources will be required to audit these organizations; as such, the overall pricing for these services will be higher. In addition, these businesses face larger, more complex reporting requirements, as well as different regulatory environments that must be considered based on their activities in each country. The additional effort and expertise required to perform audit work in an international environment result in higher fees for these services.
Type of industry
Every industry and its different sectors will have their own regulatory environment or accounting standards. Specialized knowledge and skills are increasingly important for auditors in heavily regulated industries like health care and financial services because of the need to have these skills due to increasing amounts of complex and numerous regulatory requirements, as well as the need for auditors to fulfill specific reporting requirements. As a result, auditors in these industries may charge higher rates for audit outsourcing services.
Additionally, as technology continues to evolve rapidly, auditors must be adept at being informed about new technologies and related risks, thereby substantially increasing audit costs. Each industry has its own unique risk profile, may have valuation issues with its assets, or may have specific compliance obligations, requiring auditors to follow extensive, comprehensive audit processes.
Risk profile of the business
The inherent risks within companies primarily influence the total cost of an audit. Factors that affect inherent risk and, consequently, audit costs include:
- A company operating in a highly leveraged environment
- A company operating in a volatile environment
- A company with a history of operating at a loss
When inherent risks increase, the auditor must perform additional testing and carry out a more comprehensive assessment of the company’s financial statements. As a result of higher intrinsic risk, the auditor may need to conduct more substantive procedures, extend the audit over time, increase the number of audit samples, and/or utilize specialized or costly audit methods, all of which lead to higher audit fees.
Level of internal controls
Effective internal control systems are one of the most significant drivers of audit costs. When internal controls are strong and financial records are kept in an orderly manner, the audit process can be streamlined because the auditor can rely on the company’s systems. This allows the auditor to reduce the number of substantive tests required to complete the audit. However, if internal controls are weak, the auditor is required to conduct more detailed transaction testing, which will, in turn, incur additional audit costs.
Additionally, if internal controls are poor, the auditor may be required to provide recommendations for improvement or assist the company in implementing them, which increases the scope and cost of the engagement.
Factors Related to the Audit Provider & Engagement
Companies must take steps to prepare for their company audit to ensure a successful conclusion. To prepare for their company audit as part of the company’s overall audit process, companies should address issues identified throughout the company audit process prior to the auditor conducting a follow-up audit and provide accurate records of the company’s operations.
Completing the company audit preparation can help reduce unnecessary re-audits, delays in delivering auditors with documented information, and additional billable hours auditors may incur after the company audit has been initiated.
Receiving an organized approach and prompt responses to customer requests typically results in auditors spending less time on customer audits than on those customers that are not providing organized, prompt responses to their requests for information. Conversely, a disorganized customer response may require extensive follow-up and retesting by auditors and, as a result, increase audit duration and customer costs.
Outsourcing firm’s reputation
Reputable companies with significant experience (well-known) charge more than less-expensive organizations because clients pay for the security that comes from having a well-known name and the large number of people available to assist them with high levels of expertise. When a firm has a strong reputation for efficiently managing complex audits, providing clients with high-quality insights into their businesses, and ensuring regulatory compliance, that is what gives it the right to charge a premium price for its services.
Service model chosen
The model chosen for support will have different costs (for example: fully outsourced to an overseas partner versus employed in-sourcing, which allows for quality control and management to be provided on-site) depending on whether one uses solely offshore teams (most often, through cheaper labor) or blends that with in-house teams.
For the most part, this means outsourcing audit will save money because labor is cheaper. However, there are other important factors in using offshore versus onshore services that affect costs, including communication challenges, quality assurance issues, and delays due to time differences. Each client will consequently evaluate their need to save money or to have an expert locally to ensure proper oversight.
Scope and add-ons services rendered
The identified depth of an audit and related requested services can drastically impact on the overall cost. Specialized Accounting/Forensic Accounting Procedures/Audits of compliance require additional time and potential costs. In most cases, these add-ons will include the services of highly skilled professionals and generally require the use of proprietary tools, resulting in a significant markup on fees. The more clearly the audit scope and any additional requested services are defined at the outset, the easier it will be to establish the expectations of all parties and to avoid additional charges.
