Common SOX Compliance Mistakes Companies Make When Scaling

Services: SOX Compliance

---

Growth changes a company faster than most compliance programs can keep up. New product lines, new locations, and new hires all reshape how a business operates, but many finance teams keep running their SOX program the same way they did the year before. That gap between a fast-moving company and a static compliance framework is where mistakes creep in.  

6 Common SOX Compliance Mistakes 

This article looks at the most common missteps companies make with SOX compliance as they scale, and how to avoid them.  

1. Carrying Forward Controls Without Reassessing Them 

Many companies treat their control framework like a checklist from last year’s audit. They copy it forward, add a few line items for new systems, and call it done. The problem is that a control designed for a fifty-person company rarely fits the same organization at five hundred people. Processes change, ownership shifts, and risks move to new areas of the business. When controls stay frozen in place, teams end up testing things that no longer matter while missing the risks that grew alongside the company. 

2. Letting Documentation Lag Behind Process Changes 

Scaling companies change their processes constantly, often without updating the paperwork that describes them. A new approval workflow gets rolled out, a manager takes over a task from someone else, or a spreadsheet gets replaced by a system, and the control documentation still describes the old way of doing things. Auditors notice this gap quickly, and it usually points to a bigger issue: the company isn’t tracking its own process changes closely enough to keep documentation current. An accounting transformation can create similar documentation gaps when processes and technology change faster than the control environment.

3. Underestimating IT General Controls During System Changes 

Companies that scale usually change their technology stack, too. They implement a new ERP system, add a CRM, or move financial data into a new reporting tool. Each of these changes affects access controls, change management, and data integrity, all of which fall under IT general controls. Teams sometimes assume that a new system is automatically more secure than the one it replaced, which isn’t always true. A poorly configured system can introduce new risks even as it solves old problems. 

4. Failing to Update the Risk Assessment After Growth Events 

Mergers, acquisitions, new office locations, and expanded product lines all change a company’s risk profile. Yet many organizations run their annual risk assessment as a formality rather than treating it as a living exercise. This leads to blind spots. A newly acquired subsidiary might operate on different systems with different controls, and if the risk assessment doesn’t account for that, neither will the SOX program. Growth events should trigger a fresh look at where the real risks sit, not just an update to a spreadsheet. 

5. Treating SOX as an Annual Event Instead of a Continuous Process 

Some companies still approach SOX compliance as something that happens once a year, right before the audit. This mindset works fine when a business is stable, but it falls apart during growth. Controls that were adequate in January can be irrelevant by September if the company has added new revenue streams or restructured a department. Building small, regular check-ins into the compliance calendar catches problems early, rather than leaving teams scrambling to fix gaps right before testing begins. 

6. Overlooking Segregation of Duties as Teams Grow Fast 

Rapid hiring often outpaces the planning needed to keep segregation of duties intact. A finance team that doubles in size within a year may end up with new employees inheriting responsibilities without anyone checking whether that combination of duties creates a conflict. This mistake is easy to miss because it happens gradually, one hire at a time, rather than as a single decision anyone would flag on their own. 

Working with BPM 

Scaling a business is hard enough without a compliance program that fights against it, which may signal that it is time to outsource SOX compliance. BPM’s SOX Compliance services work with growing and pre-IPO companies to build SOX programs that flex with the business instead of holding it back. That means rationalizing controls that no longer serve a purpose, keeping documentation aligned with how the company operates, and updating risk assessments as new locations, acquisitions, or systems come online.
