What Is a Corporate Controller? Role, Responsibilities & Why It Matters

Introduction 

A company’s financial health and success are paramount, especially when starting a new business or considering an expansion of your existing venture. To ensure that your business is taking the right step forward and making the right economic moves, implementing the proper accounting methods becomes essential. For this reason, it is crucial to hire a corporate controller. In this blog, let us explore what a corporate controller is and how they differ from other finance professionals.  

What Does a Corporate Controller Do? 

A corporate controller is responsible for all the company’s accounting-related activities. Some of the responsibilities include high-level accounting, administrative accounting, and finance activities. They are also responsible for advising and reporting on material budgeting modifications or expenditure variances to management. Depending on the type of company, the role of the corporate controller varies. Let us now understand the role of a corporate controller in a small and medium-sized enterprise (SME).  

Role of a Corporate Controller in an SME 

Professionals need to have astute knowledge of small business accounting if they want to be a controller in small to medium-sized organizations. Although you can do this work as a sole proprietor, it needs to be delegated to an accounting expert. Here are a few essential facts about this position  

Knowledge of small business accounting is necessary to become a controller who oversees accounting and bookkeeping. A sole proprietor can handle this job, but as the company expands, the work can be delegated to an accounting expert. The work of a corporate controller in an SME can involve: 

• Supervising the preparation of the annual accounts of your company. 

• Defining the business expense categories 

• Ensuring full compliance with accounting and tax obligations 

• Detecting errors and deviations 

• Suggesting areas that need improvement from a financial perspective 

• Implementing methodological tools to control accounting activities in your business 

• Managing your company’s treasury 

• Supervising the funds required to take care of common investments 

• Training and motivating the finance and accounting personnel 

• Reporting all finance-related matters to senior management 

Role of a Corporate Controller in a Large Corporation 

In a large company, especially one with multiple subsidiaries, the corporate controller’s role goes beyond day-to-day operations. Instead, they focus on key financial and strategic responsibilities, such as: 

• Overseeing the preparation of both individual and consolidated financial statements for the entire company. 

• Setting up and monitoring strong internal controls. 

• Establishing company-wide accounting standards and procedures. 

• Managing and improving financial reporting systems. 

• Leading cross-functional projects related to strategy, IT, finance, or accounting. 

• Monitoring the company’s financial goals, including budgeting, investments, and financing. 

• Contributing to the development of the company’s overall business strategy. 

The Importance of a Financial Controller 

You need to hire a skilled and experienced corporate controller for your company. A talented financial controller is priceless. Thus, you must pay full attention to who you hire as a corporate controller. On this decision hinges the economic stability and success of your company, as your company’s overall performance will largely depend upon your controller’s competence.
