An accountant must keep order and hold a structure that keeps records for the company's financial well-being. They do so by accounting for all earnings and expenses flowing through the company. A successful accountant makes sure to educate employees about how to report their expenses, for accountability of all information in due timing, and transparency with honest statements. 

In this article, we review some key elements of auditing expense reports. Read on for more information on guiding your clients through an expense report audit. 

How to audit expenses?

An audit is a revision of proof. Businesses conduct audits to establish the existence, truth, or validity of the evidence or the logic used in the report that was presented by the accountant. 

Any non-business related expenses claimed as business expenses will raise a flag. Further, it can lead to an audit investigator asking for proof related to the expense. This means you will have to show the invoices, all contracted purchases, and more to confirm the integrity of your claim. 

Why is auditing expense reports important?

Your employees incur a variety of business expenses. This can include buying supplies for the company, paying for business meals, travel expenses such as airplane tickets and ground transportation, workshops, training, or any services and products requested in the name of the company.  

When your employees use their money to make business-related purchases, the onus of reimbursement falls upon the business. While some employees may stay honest and report actual expenses, there are many more who may either inaccurately report or altogether misreport business expenses. 

Expense fraud comes in various sorts. Be it a minor number change in the form of a manual error or an out-right submission of duplicate bills or receipts.

When a business ignores and reimburses its employee for fraudulent claims, it not only results in a reduction in revenue but also poses a threat to getting into trouble with the IRS. Hence the objective of auditing expense reports is to balance the bottom line while also staying per the law. 

Auditing expense reports allow businesses the opportunity to revisit documents and receipts presented by the employee in the form of expense reports. These expense reports work as evidence to ensure all expense reports comply with your travel policies. They also ensure you always stay audit-ready!
