What Are the Key Differences Between CEO, CFO, and COO? A Guide for eCommerce Business Owners

If you're running a growing eCommerce brand and feeling confused about executive roles, you may have wondered about the differences between these key C-suite positions.

CEO ( Chief Executive Officer ) - Overall company vision and strategy
CFO ( Chief Financial Officer ) - Financial strategy and management
COO ( Chief Operating Officer ) - Day - to - day operations and execution
Leadership alignment and vision
Cross-functional team coordination

Judith helped drag the accounts and analytics of our fashion ecom business out of a messy and chaotic place. She is a clear thinker, with a strong strategic mind, and is able to provide a clarity of thinking that is necessary when it comes to finance. Judith has a wealth of experience and brought not just practical hands-on implementation, but also guidance on industry benchmarks, and how to put our figures in a broader context. We spent just over 6 months cleaning up accounts and putting in place new finance streams and processes for the business. She helped kickstart the beginning of a journey we hope to move forward into future success!

Judith is a lightning bolt of clear thinking & decisive action. She recently started working with our eCommerce business to give us clarity in terms of financial decision making, and has been able to shed tremendous insight into what has been a daunting area for us as small business owners - financial analytics. Judith has a wealth of expertise and is as competent deep diving into bookkeeping minutiae as she is building marketing dashboards, cashflow forecasts, and providing top level business strategy (amongst many other things!). As a small business owner it's hard to be strong across all areas of business, and for us, in terms of the financial landscape, it is very much a case of 'we don't know what we don't know'- Judith is who you want to talk to to help fix that. Highly recommend.

Frequently Asked Questions

What's the difference between a CEO, CFO, and COO?

While CEOs focus on overall company vision and strategy, CFOs handle financial management, and COOs oversee daily operations. CEOs make high-level business decisions, CFOs provide financial expertise and analysis, and COOs ensure efficient execution of plans.

How do CEO, CFO, and COO roles work together in business growth?

Understanding the differences between C-suite roles can help eCommerce founders improve organisational visibility, strengthen decision-making, and put scalable systems in place. By guiding you on executive team structure, management frameworks, and strategic planning, they ensure your growth is sustainable and backed by proven leadership principles.

When should a company consider adding these different executive roles?

What are the typical salary ranges for CEOs, CFOs, and COOs?

Can one person hold multiple C-suite positions in a small business?

What qualifications should I look for when hiring for these executive positions?

The collaboration between CEO, CFO, and COO is essential for sustainable growth. While a founder might handle multiple roles in the early stages, these distinct responsibilities become crucial as the business scales. The CEO focuses on vision and strategy, the CFO manages financial planning and analysis, and the COO ensures operational excellence and execution.
CEO, CFO, and COO salaries vary widely based on company size, industry, and growth stage. CEOs typically earn the most due to their ultimate responsibility for business performance. CFOs' compensation reflects their strategic financial leadership, while COOs are compensated for operational oversight. Each role includes various incentives like bonuses and equity. The real difference lies in their distinct responsibilities rather than just compensation.
Yes, but it's extremely challenging. While one person can technically handle CEO, CFO, and COO responsibilities in a smaller business, it means juggling strategic leadership, financial management, and operational oversight. This often leads to competing priorities and missed opportunities. Through mentoring, I help founders assess whether separating these roles or managing them effectively is the best path for sustainable growth.
For CEOs, look for strong leadership, strategic vision, and decision-making abilities. CFOs should have financial expertise, analytical skills, and strategic planning capabilities. COOs need operational excellence, process optimisation skills, and strong execution abilities. All three should have excellent communication skills, but their technical expertise areas differ significantly.
