What Does a Chief Operating Officer Do in a Small Business?

Ask ten business owners what does a chief operating officer do, and you will probably get ten different answers. That is because the role changes from company to company. In a large corporation, the COO may run thousands of people. In a small business, the job looks quite different, and it can be a real turning point for an owner who is tired of doing everything.

As someone who founded and runs a digital marketing agency, I have seen how much easier life gets when someone takes ownership of the day-to-day running of the business. This guide explains the role in plain English, what the COO role and responsibilities usually include, and how to tell whether your business is ready for one.

What does a chief operating officer do?

A chief operating officer, or COO, is the senior leader who looks after how the business actually runs, day to day. If the chief executive or owner decides where the company is going, the COO makes sure the people, processes and systems are in place to get it there.

The short answer to what does a chief operating officer do is that they own the running of the business, so the owner does not have to.

Reference sources describe the COO as the person who runs daily operations, including people, resources and logistics, and who usually reports directly to the chief executive. In many firms they are second-in-command and step in when the chief executive is away.

When someone asks me what does a chief operating officer do in a business with ten staff, I explain it like this: the owner points at the horizon, and the COO makes sure the ship is running smoothly while it heads there.

COO role and responsibilities in a small business

There is no single official job description. The COO role and responsibilities depend heavily on the owner, the industry and the size of the team. Still, most small business COOs cover a handful of core areas.

Running day-to-day operations

This is the heart of the job. The COO makes sure work is delivered on time, to a good standard, and without the owner having to chase it. They keep an eye on workloads, deadlines and quality, and they step in when something slips.

Building and improving processes

Small businesses often grow on habits and good intentions. A COO turns those habits into clear, repeatable ways of working. That might mean writing down how a new customer is onboarded, how projects are handed over, or how invoices go out. The aim is simple: the business should not fall apart if one person is off sick.

Managing people and teams

A COO usually oversees team leaders, sets expectations, handles performance and keeps morale healthy. They often lead recruitment, training and the way the team is organised, so that the right people are doing the right jobs.

Managing budgets and resources

Time, money and people are always limited. A good COO decides where those resources go to create the most value. They track costs, watch margins and flag problems early, rather than waiting for the end of the year to find out.

Turning strategy into action

Owners are usually full of ideas. The COO takes the plan and breaks it into steps, owners and deadlines. They also report back on progress, so the owner can see whether things are really moving.

Tracking performance

Most COOs use a simple set of numbers, such as delivery times, customer satisfaction, profit by service and staff workloads. Sources on the role often mention dashboards, and for a small firm that can be as simple as a shared spreadsheet reviewed every week.

Looking after customers and suppliers

Operations does not stop at the office door. A COO often makes sure customers get a consistent experience and that suppliers and partners are managed well. If you want to see what a good start looks like, take a look at our guide on how to welcome a new client.

How a COO differs from a CEO

Understanding what does a chief operating officer do compared with the person at the top clears up a lot of confusion.

• The CEO or owner sets the vision, makes the big decisions, builds key relationships and is ultimately accountable for the business.
• The COO makes the vision work in practice, running the machinery of the business and the people inside it.

The two roles work best when there is trust and clear boundaries. A COO needs to know which decisions are theirs to make, and an owner needs to resist the urge to reverse them. That kind of clarity is one of the biggest factors in whether the partnership succeeds.

COO vs operations manager vs general manager

Small businesses often use these titles loosely, so it helps to see the differences.

• Operations manager: usually focuses on running a team or process, and is often a step below director level.
• General manager: typically runs a single location, brand or division, with a wider remit across sales, delivery and people.
• COO: sits at the top table, shapes company-wide decisions and carries responsibility across the whole business.

In very small companies one person may do all three jobs. The title matters less than the work. What matters is that someone owns the running of the business.

Signs your small business may need a COO

Before asking what does a chief operating officer do for you, check whether the owner has become the bottleneck. You do not need one the day you hire your fifth employee.

These are the clearest signs.

• You are involved in almost every decision, however small.
• Deadlines slip, or quality varies depending on who did the work.
• You spend your week firefighting and never reach the strategic work.
• Your team keeps asking you how things should be done.
• You want to grow but are afraid things will break.
• You have not had a proper break in years without checking your phone.

If several of these sound familiar, the problem may not be your team. It may be that the business has outgrown the way it is run. Learning to hand work over is a skill in itself, and our guide on how to delegate as a business owner is a sensible first step before you commit to a senior hire.

What skills does a good COO need?

Whether you hire full time or part time, look for these qualities.

• Organisation: they enjoy structure, planning and follow-through.
• Clear communication: they can explain priorities to the team and report honestly to the owner.
• People skills: they can coach, challenge and support without drama.
• Commercial sense: they understand how decisions affect cash and profit.
• Problem solving: they stay calm and fix root causes, not just symptoms.
• Complementary strengths: they are strong where the owner is weaker. If you are the ideas person, you need a finisher.

Do you need a full-time COO?

Not necessarily. Many small businesses cannot justify a full-time senior salary, and that is perfectly normal. There are a few ways to get the benefit without the full cost.

• Promote from within: a trusted senior team member steps up into an operations leadership role.
• Hire a full-time COO: best when the business is large or complex enough to need someone every day.
• Bring in a fractional COO: an experienced operator who works with you for a set number of days each week or month.

If you are weighing these up, our comparison of a fractional COO versus a full-time COO goes through the pros and cons in more detail.

What does a chief operating officer do in the first 90 days?

A new COO rarely starts by changing everything. A sensible first few months usually look something like this.

• Listen and learn: meet the team, understand the customers and see how work really gets done.
• Map what exists: write down current processes, tools, costs and pain points.
• Pick quick wins: fix a few small frustrations early to build trust.
• Agree priorities and measures: decide with the owner what success looks like and how it will be tracked.
• Start a regular rhythm: weekly team check-ins and a monthly review are a good start.

That is the practical answer to what does a chief operating officer do once they arrive. This pace gives the team time to adjust, and it gives the owner confidence that the business is in safe hands.

How to get the best from your COO

A COO cannot succeed on their own. A few habits from the owner make a big difference.

• Be clear about decision rights. Write down what the COO can decide alone and what needs your approval.
• Back them in public. If you disagree, talk privately, then present a united front to the team.
• Share the real numbers. They cannot manage what they cannot see.
• Let go gradually. Hand over one area at a time, and resist the urge to step back in at the first wobble.

Frequently asked questions

What does a chief operating officer do compared with a managing director?

A managing director usually has overall responsibility for the business, much like a chief executive. A COO focuses on running operations and typically reports to that person.

Is a COO the same as an operations director?

They overlap. A COO is generally a more senior, company-wide role, while an operations director may look after operations only, and may not sit on the main leadership team.

Can a small business have a COO?

Yes. Many small and owner-managed businesses benefit from one, either as a full-time hire, a promoted team member or a part-time fractional COO.

What is the difference between a COO and a CEO?

The CEO sets direction and is ultimately accountable. The COO runs the day-to-day operations that turn that direction into results.
