Vendor Audits

The complexity of the purchasing process can lead to errors that can increase the risk of significant financial loss if not quickly detected and resolved.

Overpayment can be attributed to a variety of errors, including miscalculations, duplicate payments, neglected rebates and allowances, misunderstanding of contract terms, tax overpayment, and charges for goods and services not received.

Doeren Mayhew’s Internal Audit Group includes vendor audit specialists to help your organization improve vendor relationships and avoid financial loss by identifying process control issues and analyzing invoices, contracts and other related data to detect potential overpayments.

Our specialists have performed vendor audits for a variety of businesses, including oilfield service providers, construction companies, engineering firms, legal firms, security services companies, trucking and rail car businesses, and more.
