The short answer: The best time to hire a fractional COO is once your business has crossed roughly $3 million in revenue and you have proven, year over year, that your model works: you know what you sell, who buys it, and that they keep buying. At On Call COO, I also tell founders not to wait for chaos. Bringing in a COO six to twelve months before things break is far cheaper than repairing them after.
If your business feels more chaotic every month, or growth has stalled and good people keep leaving, you are probably wondering whether it is time for real operational help. Most founders I talk to ask that question too late.
I'm Melissa Franks, founder of On Call COO, a former Fortune 500 COO, and host of The Optin Podcast. I joined the Business Growth Podcast as a guest to talk about what a fractional COO does, the revenue number I use to decide when a business is ready, the biggest misconceptions, and how we grew On Call COO using the same approach.

What Does a Fractional COO Actually Do?
A fractional COO is a seasoned chief operating officer who works with your business part time, helping you build a strategic plan and then execute it operationally, at a fraction of the cost of a full-time executive. At On Call COO, that means we do not just advise. We roll up our sleeves and get the work done.
The COO role is hard to understand, and that is somewhat by design. A COO is the yin to the founder's yang. We are a bit like chameleons, strong where the founder is weaker: if you are product focused, we bring the systems, and if you love systems but sales is not your strength, we help there.
Our team is made up of what I call corporate dropout COOs from Fortune 100 and Fortune 500 companies, now working inside seven- and eight-figure businesses. When it helps, we bring operations managers with us so we can move the needle quickly.
Why big-company experience matters for a small business
Most small business teams learned inside other small businesses, in small containers. Our COOs come from multi-billion-dollar global companies where we have broken businesses apart, put them back together, sold them and grown divisions. I call this a credentialed skill set, and the fractional model makes it affordable for a business doing a few million dollars a year.
When Should You Hire a Fractional COO? The $3 Million Rule
The right time to hire a fractional COO is usually once you reach about $3 million in revenue and you have consistently generated revenue year over year, which proves you have a model that works. Below that, you are still mostly testing and experimenting.
Here is how I think about the stages of a business. Every business is different, but this pattern holds up well.
1. Up to $1 million: hustle can get you there
If you hustle hard enough and you have something people will buy, you can get to a million dollars on your own, even once without a repeatable system behind it.
2. $1 million to $3 million: the experimentation zone
The $1 million to $3 million range is where the real experimentation and testing happens. This is where you find out whether you have something viable and whether the business will stand the test of time.
3. $3 million and up: the perfect time to bring in a COO
Once you hit $3 million and have been able to generate revenue consistently year over year, you know you have a model that works. You know who your clients are and what you are selling. That is the perfect time to bring in a COO, because now the job is to take something with real demand and build the operations to grow it sustainably.
You can bring in a COO earlier, but they will mostly be helping you experiment, and that is not our sweet spot. That is why our Hands-On Fractional COO service, which starts at $7,500 per month, is designed for businesses at $3 million and above. For earlier-stage founders who want strategic guidance, our COO Advisory option starts at $3,000 per month.
Growth means something different for everyone
We are not promising to take every business from $3 million to $100 million. For some founders, the goal is to reach $5 million, have someone else run it and travel six months of the year. We start with what you actually want.
What Are the Signs You Waited Too Long to Hire a COO?
The clearest signs you waited too long are a business that feels chaotic, growth that rose fast and then plateaued or started declining, and employees who keep leaving. These are symptoms of break points that could have been fixed earlier.
When small business owners come to us, they usually describe one of three things:
- "The business is chaotic."
- "We were growing really rapidly, then we plateaued, and now we're declining."
- "I can't keep employees. They keep running out the door."
What we find again and again is that if we had come in six months or a year earlier, when growth felt good, we could have spotted the small break points and said, "Let's fix this now so you don't hit the plateau, you don't hit the decline and your people don't leave." You want a COO in place before the chaos hits, because the earlier we are in the room, the more often we can help you avoid that place entirely.
What Is the Biggest Misconception About Fractional COOs?
The biggest misconception is that a fractional COO only gives advice. The second is that a small business is too early to need this level of support. Both cost founders time and money.
Misconception 1: "They just give advice"
I call it talking head support: someone tells you what you should do but never actually helps move the needle. A good fractional COO builds the plan and then executes it with you.
Misconception 2: "We're too small for a COO"
Many founders assume it is too soon for COO-level expertise, so they tap in too late. If your model is proven, you are not too small. You are at exactly the point where operational structure matters most.
Misconception 3: "I should learn to do it myself"
We tried hosting masterclasses, webinars and free trainings, and found that the founders who need us most are buried in work. They do not have hours to learn how to run operations. They want somebody to do it for them, which is reasonable when your time is the scarcest resource in the business.
How On Call COO Followed Its Own Advice to Grow
I left my COO role at a large financial services company in 2022, tried a startup for about nine months, and in the fall of 2023 took on one client as a solopreneur. In 2023, we collected $9,000 in cash. In 2024, we collected about $275,000. Last year we reached about $850,000, and this year we are on track for $3 million. The turning point came in the spring of 2025, when demand exceeded my personal capacity and experienced COOs started asking to join.
1. Define what you are, and what you are not
We decided early that we were not a staffing agency. We are a professional services firm, closer to management consulting, and we got just as specific about which clients we serve as about who joins our team.
2. Protect quality as you scale
We receive 25 to 30 employment applications a month. Hiring faster would risk mismatched clients and COOs and degrade the brand, so we scale slowly and intentionally.
3. Plan for a graduation, not forever
We love it when clients graduate from us. Our sweet spot is staying with a business for about 12 to 18 months, long enough to set it up well for the future.

Frequently Asked Questions
When is the right time to hire a fractional COO?
The right time to hire a fractional COO is usually once your business has reached around $3 million in revenue and has shown consistent results year over year. At that point you know what you sell and who buys it, so a COO can focus on scaling a proven model. Hiring earlier is possible, but the work tends to be experimentation rather than building for growth.
What does a fractional COO do for a small business?
A fractional COO works with a small business part time to build a strategic plan and then carry it out operationally. They fill the gaps where the founder is less strong, whether that is systems, processes, team structure or sales operations. The best fractional COOs roll up their sleeves and implement, not just advise.
What are the signs my business needs a COO?
Common signs include a business that feels chaotic, rapid growth that has stalled or begun to decline, and difficulty keeping employees. These problems usually trace back to small operational break points that went unaddressed as the company grew. If you are seeing them, it is worth bringing in a fractional COO or outside operations help before they compound.
Is my business too small for a fractional COO?
If your business is still under $1 million or is actively testing what it sells, you may get more value from focusing on proving your offer first. Once you have a repeatable model, usually somewhere around $3 million in revenue, a fractional COO can make a meaningful difference. Many founders wait too long because they assume they are too small, when they are actually right on time.
How long does a fractional COO engagement usually last?
Many fractional COO engagements work best over about 12 to 18 months. That is typically enough time to set up strategy, systems and team structure so the business can keep running well on its own. A good fractional COO plans for the client to eventually graduate rather than staying forever.
Not Sure If It's Time to Bring In a COO?
If you are past the experimentation stage and the business is starting to feel heavier instead of easier, that is the window where a fractional COO makes the biggest impact. At On Call COO, we match you with an experienced COO in 48 hours, give you operational clarity within 14 days and aim for your first measurable win within 30 days.
