Is your business getting what it needs from the Controller role

Not all Controllers are created equal

As private companies grow, financial complexity increases; but the financial function doesn’t always keep pace. It’s common to reach a point where leadership realizes: the numbers are getting harder to trust, reporting takes longer than it should, and there’s a growing sense that no one is truly “on top of it.”

That’s usually when someone steps up or is promoted into the Controller role; someone reliable, sharp, and already familiar with the business. But over time, it becomes clear that the business needs more than what the role is currently delivering.

This isn’t about titles. It’s about whether your finance function is providing structure, insight, and accountability; or simply keeping things afloat.

What a High-Performing Controller Actually Brings

Controllers play a critical role in making sure a business doesn’t just grow — but grows in control. They create the systems and discipline that turn financial data into operational clarity, enabling faster and more confident decisions. Here’s how they contribute in a meaningful way:

Financial Accuracy and Process Discipline

A Controller ensures that the numbers are accurate, the books close on time, and reporting follows a consistent rhythm. But more than that, they build repeatable processes that scale with the business. Financial information isn’t reactive or delayed; it’s proactively managed and ready when leadership needs it.

Real-Time Performance Visibility

A strong Controller doesn’t just report on past performance; they help the business understand where it’s headed. They compare actuals to plan, flag deviations early, and work with business leaders to take corrective action. This brings real accountability to budgets, forecasts, and operating plans.

Budgeting and Forecasting That Reflect Reality

Many companies have a budget, but few use it as a day-to-day tool. A Controller helps build and maintain living forecasts that guide decision-making. They connect the numbers to business drivers and ensure that leadership is working from a financial roadmap that reflects what’s really happening.

Cost Control and Margin Protection

As companies grow, costs grow with them; but not always intentionally. Controllers help identify where spending is creeping, margins are thinning, or cash flow is tightening. They provide a level of financial oversight that keeps the business focused on profitability and sustainability, not just top-line growth.

Financial Partnership with the Business

A Controller doesn’t just sit in the back office. The most effective ones are embedded in the business; meeting with leaders, asking questions, and using financial insight to support operational decisions. They act as a partner, helping leadership stay financially grounded even during rapid change.

When the Title Doesn’t Match the Responsibility

In many companies, the person holding the Controller title is capable and committed; but may not have the experience or tools to deliver the full scope of what’s needed. They might be a promoted bookkeeper or accountant, excellent at managing transactions but not trained in financial operations, forecasting, or performance management.

This isn’t a failure; it’s just a common inflection point for growing businesses. And it’s often a sign that your company has outgrown its current financial structure, even if no one has said it out loud yet.
