Fractional COO vs Full Time COO: what each does and when to hire one

I’ve sat in the full-time COO seat. At Tivic Health I joined as employee number five and ran the company’s operations, with the P&L, interim CFO duties and the board reporting that came with them, all the way to a NASDAQ listing. Today at PILTA, we put senior operators into growing companies part time. So when a founder asks me whether they need a full-time COO or a fractional one, I can answer from both sides.

Most companies get to this question the same way. Orders start slipping. The “ERP” is three spreadsheets and a shared inbox. Every decision waits on the founder, and the founder is also the person emailing the 3PL at 10 p.m. Something has to give, and the first idea is usually to hire a COO.

Here’s how I’d think about the choice.

What is a fractional COO?

A fractional COO is a senior operations executive who works with your company part time, usually somewhere between 5 and 40 hours a week, for as long as you need them. They run what a COO runs: the operating plan, the people, the systems, the vendors and the numbers. You pay for the hours you use.

A good one doesn’t feel part time to your team. They’re in the weekly meeting, they know the numbers cold, and when the 3PL misses a cutoff, everyone knows who’s making the call.

What does a fractional COO do?

It depends on where the company is, but a typical month looks something like this:

• Running the operating rhythm: the annual plan, the budget and the KPIs, plus the weekly and monthly meetings that keep everyone honest about them.
• Holding suppliers to account: contract manufacturers, suppliers and the 3PL, including the hard conversations about cost of goods.
• Fixing the systems: choosing the ERP, warehouse and order management tools before volume breaks the spreadsheets, or rescuing the ones you already bought.
• One plan for the whole company: demand planning and sales and operations planning, so sales, operations and finance stop working from three different forecasts.
• Building the team: the org chart for where you’ll be in a year or two, and the first operations, supply chain and customer support hires to get there.
• Getting ready for the big moments: a retail launch, Amazon, a new product line, a fundraise or an acquisition.

Fractional COO vs full-time COO

Both roles run operations. The real differences are time, cost, commitment, and what each person is in the seat to do.

A full-time COO is a company officer. They’ll usually ask for shares, they take on the personal liability that comes with an officer title, and the company carries D&O insurance to cover them, on top of salary and health and benefits pay. That’s a fair ask. They’re tying their career and their personal risk to your company for years, so they look at every decision as an owner, through their own executive risk profile.

A fractional COO comes in with a different job: drive profitability and carry out the plan the CEO and the board have set, inside the values and goals you already have. There are no shares, no officer liability, no D&O policy and no benefits package. The responsibility, the weight of the role, the level of buy-in and the direction are different. For a lot of growing companies, that difference is the advantage.

	Full-time COO	Fractional COO
Hours	Full time	Usually 5 to 40 hours a week
Start	After an executive search	Soon after a first call
Commitment	Long-term employment as a company officer	A contract that can grow, shrink or end
Cost	Salary, health and benefits pay, shares, D&O insurance and officer liability, plus the search	Paid for the hours or a defined scope. No shares, benefits, D&O insurance or officer liability
Outlook	Ownership and executive risk	Profitability, and the CEO’s and the board’s values and goals
Best fit	Operations need a leader on site every day	You need senior operating leadership now, before you can justify or find a full-time hire

How it plays out is up to you, and it works every way. Some companies keep their fractional COO for the long run. Some convert the role to full time once the fit is proven and the company is ready. Others have the fractional COO keep the seat warm, building the plan, the systems and the team, until a full-time COO takes over a running operation.

Fractional COO vs consultant

A consultant is usually hired to study a problem and hand over a recommendation, and your team does the work after the engagement ends. A fractional COO stays for the work. They own the plan, manage the vendors, sit in your leadership meeting every week and answer for the numbers.

If you need an outside read and your team has room to act on it, a consultant may be all you need. If you need someone to carry the decision through to the result, that’s the fractional COO.

When to hire a COO

The clearest sign: you, the founder or CEO, spend more time on operations than on customers, product and capital, and the operation is still breaking as you grow. Other signs I see often:

• Customers notice: late orders, stockouts, the wrong item in the box.
• The business runs on spreadsheets and QuickBooks, and the month-end close takes weeks.
• A big launch is on the calendar: a new retail account, Amazon or a new product line.
• Investors, a lender or a buyer want clean numbers and a plan they can believe.
• Everyone still reports to you.
• Revenue is going up and margin is going down.

A fractional COO usually fits first when:

• Budget is tight. You need senior operating leadership, and a full executive package isn’t in the plan yet.
• You want to try before you buy. Fit, culture, experience and style get tested on real work before anyone signs a long-term offer.
• You needed help yesterday. An executive search takes time, and the problems on your desk won’t wait for it.
• There’s a gap between strategy and execution. The plan is right, and it isn’t getting done.
• The CEO is the bottleneck for daily decisions and progress.
• You need someone in the seat while you search for a full-time COO.
• The build has a finish line, such as an ERP rollout, a 3PL move or a launch.

A full-time COO usually fits when:

• operations need a leader on site every day;
• the role will lead a large team for years;
• the company is ready to fund the full package and the search.

Fractional COO cost

Fractional pricing is straightforward. Most fractional COOs work on a monthly fee for a set number of hours, or a fixed fee for a defined project, and the hours can go up during a launch and down when things are steady.

The number founders tend to underestimate is the full cost of a full-time COO. Add it up:

• salary
• health and benefits pay
• shares or other equity
• D&O (directors and officers) insurance
• the liability the company takes on with an officer
• recruiting fees and the time the search takes

A fractional COO carries none of the shares, benefits, D&O insurance or officer liability, and there’s no recruiting fee. You pay for the operating leadership itself.

At PILTA, a defined project is a flat fee, and fractional and embedded work is sized to the hours your business needs, from five hours a week to forty.

What to look for in a fractional COO

• They’ve been where you’re going. Ask about companies at your size and the size you’re growing into.
• They know your industry: the channels, manufacturing and supply chain your products depend on.
• They’ve run the systems themselves: NetSuite, SAP or Dynamics, Shopify, Amazon Seller Central, at the level of leading the implementation.
• They’ve managed vendors directly: contract manufacturers and 3PLs, including the difficult calls.
• They work inside your team: your meetings, your tools, your people.
• Their references are the people they reported to: CEOs, CFOs and boards.
