In the fast-paced world of small and medium-sized enterprises (SMEs), every pound and every hour counts. With rising operational costs and increasing competition, it can be tempting for business owners to see a financial audit as a box-ticking exercise—or worse, an unnecessary expense.
For many SMEs, particularly those falling under the audit exemption thresholds, choosing to undergo a voluntary audit may not seem like a priority. But here’s the truth: an audit is far more than a compliance exercise. It is a strategic tool that adds credibility, identifies risk, and opens doors to new opportunities. For SMEs with ambitions to grow, raise capital, or simply tighten up internal controls, a voluntary audit can prove to be an investment rather than a cost.
Building trust and credibility
For businesses operating below the audit threshold—currently set at a turnover of £10.2 million, total assets under £5.1 million, and fewer than 50 employees in the UK—a voluntary audit can significantly enhance trust with stakeholders. This includes not only investors and lenders, but also key customers and suppliers. A professionally audited set of financial statements sends a strong message: this business is transparent, well-managed, and financially sound. Lenders are more likely to extend credit, suppliers may offer better terms, and investors can make more confident decisions. In competitive tender situations, having audited accounts can even serve as a differentiator.
Strengthening internal controls
An audit provides a structured review of a company’s financial systems, internal controls, and accounting practices. For owner-managed businesses—where the same individuals often handle operations, strategy, and finances—this external perspective is invaluable. Auditors are trained to spot inconsistencies, inefficiencies, or areas of risk that might otherwise go unnoticed. These might include poor segregation of duties, errors in revenue recognition, or weaknesses in IT systems. Identifying such issues early helps businesses prevent costly mistakes or even fraud in the future. Moreover, many SMEs grow organically and rapidly, often without time to stop and reassess systems and processes. A voluntary audit can act as a vital checkpoint in that growth journey, providing assurance that the financial infrastructure is scalable and robust.
Attracting investment and financing
Whether preparing for a funding round, bank loan application, or eventual sale, audited financials are a valuable asset. Investors and acquirers seek confidence in the numbers—especially when investing in early-stage or high-growth ventures. Without the assurance of an audit, due diligence becomes longer, more expensive, and riskier for the buyer or lender.
In many cases, private equity firms, venture capitalists, or strategic investors insist on audited accounts as a precondition to discussions. SMEs that already have audits in place are therefore better positioned to act quickly and negotiate from a position of strength when opportunities arise.
Supporting international expansion
For companies expanding into overseas markets or establishing subsidiaries abroad, consolidated audited accounts help establish credibility with foreign partners, banks, and regulatory authorities. This is particularly true in the US, EU, and Asia, where professional financial scrutiny is often expected as part of cross-border business relationships.
Additionally, certain government grants, R&D tax reliefs, and regulatory frameworks may require or favour businesses with audited accounts. The absence of audited figures may inadvertently limit an SME’s ability to tap into these resources.
Enhancing owner insight and decision-making
Many SME owners are closely involved in day-to-day operations but less focused on the financial data that informs long-term decisions. An audit not only provides assurance that the numbers are accurate but also sheds light on trends, margins, and cash flows that can influence strategy. A good auditor doesn’t just report problems—they provide analysis, benchmarking, and suggestions for improvement. As a result, business owners can make better-informed decisions about investment, staffing, pricing, and expansion.
When should an SME consider a voluntary audit?
While statutory audit exemptions exist to reduce the burden on smaller businesses, there are several scenarios where a voluntary audit makes sound commercial sense:
• Rapid growth or scaling operations
• Seeking external investment or bank financing
• Planning for an acquisition or sale
• Improving internal governance and risk management
• Entering joint ventures or complex supply chains
• Operating across international borders
Even businesses that are currently exempt but nearing the audit threshold would benefit from preparing early. The first year under audit can often be the most intensive, and a voluntary audit allows a company to establish processes ahead of any mandatory requirement. For SMEs, a voluntary audit is not merely about ticking a compliance box—it is about unlocking value, improving systems, and creating trust. It provides a solid foundation for growth, helps safeguard the business from financial and operational risks, and positions the company as a credible player in the market. Rather than asking, “Do we have to do an audit?”, the better question is: “What could our business gain from one?” By viewing the audit not as a cost, but as a strategic asset, SMEs can leverage it to strengthen their business and stand out in an increasingly competitive landscape.
