What is SOX Compliance?
The Sarbanes-Oxley Act mandates strict internal controls and audit trails to ensure financial accuracy and prevent fraud. Learn how SOX requirements impact accounts payable.
Quick Definition
SOX compliance refers to adherence to the Sarbanes-Oxley Act of 2002, which requires public companies to implement internal controls and maintain audit trails in financial processes. For accounts payable, this means documented workflows, segregation of duties, and complete transaction records.
- Applies to all U.S. public companies
- Requires annual internal control assessments
- Penalties include fines up to $5M and imprisonment
Understanding SOX Compliance
The Sarbanes-Oxley Act (SOX) was enacted in 2002 following major corporate accounting scandals at Enron, WorldCom, and other companies. The legislation aims to protect investors by improving the accuracy and reliability of corporate financial disclosures through strict internal control requirements.
For accounts payable departments, SOX compliance means implementing controls that ensure every payment is properly authorized, accurately recorded, and fully documented. This includes establishing clear approval hierarchies, maintaining separation between those who can approve invoices and those who execute payments, and creating audit trails that track every action taken on financial transactions.
While SOX primarily applies to public companies, many private organizations adopt SOX-like controls as best practices or in preparation for going public. Strong internal controls not only satisfy regulatory requirements but also reduce the risk of fraud and errors in financial processes.
