How Machine Learning Can Elevate Your Audit Without Increasing Costs

What is machine learning?

Machine learning is a branch of Artificial Intelligence (AI) focusing on the use of data and algorithms to emulate the way humans learn, with increasing accuracy over time as more data is processed. Like the human brain, machine learning relies on neural networks, although in this case they are artificial and lodged in a computer. Multiple connected node layers are used to process data, pass information between layers and calculate the final output.

In this way, machine learning automates analytical model building, understands patterns and makes predictions. This makes possible deep analysis of ‘big data’ within a short time frame, rather than the representative data sampling typical of legacy auditing procedures hampered by time constraints.

How machine learning can be used in auditing

Machine learning has multiple applications in auditing. It is already used by leading accounting services firms, and new functions are constantly being introduced. Some of the current machine learning audit practices include:

• Automation of manual audit tasks
• Analysis of the complete volume of data – not just a sample – including all sales and purchase records, general ledger and all other ledgers, journal entries, bank transactions, financial reports, authorities and limits, to flag transactions that differ materially from the standard
• Identification of exceptions, and potential problems or errors, including duplicate expense claims, unauthorised expenditure, incorrect amounts and suspicious suppliers or invoices
• Reading of contracts and leases to pinpoint key clauses and numbers, assess risk and highlight any anomalies

Many accounting firms and academics are already studying additional ways that machine learning can be used in financial statement audits, particularly in the risk assurance process.

In the future, machine learning may be used in fraud detection to identify speech patterns and facial expressions that suggest nervousness or deceit. It may also be possible to assess non-financial metrics such as location images and weather patterns, and analyse their likely impact on factors such as revenue or spoilage.

The benefits of using machine learning

Human auditors, released from repetitive and time-hungry tasks, have more time to use their cognitive skills to focus on review, interpretation, evaluation, systems improvement and risk assessment. Their advisory role comes to the fore, instead of being submerged in a welter of manual data processing.

As a result of the coupling of machine learning and human expertise, the audit quality is improved and it produces more accurate outcomes and predictions without automatically increasing the cost to clients.
