How Does a Fractional Executive Engagement Work? Days, Retainers, the 90 Day Plan and the Exit Clause

By Andreas Pettersson, Founder, Leaders ADAPT

Most owners who ask me how a fractional engagement works are really asking a different question. Will this be one more expensive person who shows up, writes a plan, and leaves me holding it. I understand the worry. I have hired senior people who were brilliant in the interview and gone by the second quarter. I have also been the part time executive, and I know what makes that seat work and what makes it a waste of everyone's Tuesday.

So here is the plain mechanics, from the first phone call to the day the engagement ends.

A fractional executive engagement is a fixed share of a senior leader's week, bought on a monthly retainer, pointed at two or three written outcomes, with a 90 day plan, a weekly check in, a notice clause and a planned exit. If any of those pieces is missing, you are buying advice with a calendar invite, not an executive.

How the first call and the match work

It starts with a conversation with me, not with a résumé. On that call I am listening for one thing: what is not getting done because nobody senior owns it. Sometimes it is cash. Sometimes it is an operating rhythm that collapses every time the owner travels. Sometimes it is a pipeline that only moves when the owner sells.

The HBR researchers who studied this market put it well. Tomoko Yokoi says on the HBR On Leadership episode that you have to figure out the work that needs doing before you decide which role to hire. That is the whole point of the first call. Half the owners who arrive asking for a COO need a finance led operator. Some need a revenue leader. A few need neither and should fix how they run their own leadership team first.

Once the work is clear, I match a partner from the bench and bring them into a second call. The owner and the executive agree two or three outcomes, in writing, that would make the next six months worth it. Then we agree days per week and the start date. The contract sits with Leaders ADAPT, and I stay in the room after the match, which means I sit in on the reviews, I hear when it drifts, and I am the person the owner calls when something feels off.

If you want the definitions first, read what is a fractional executive. If you are still choosing between shapes, the fractional vs interim vs advisory comparison draws the lines.

Days per week and how the time gets used

Most fractional executives work one to three days a week. KORE1, a staffing firm that places fractional leaders, puts fractional hours at 8 to 20 a week, against 32 to 40 for a contractor and 40 or more for an interim executive (KORE1, updated September 2026). Fractionus, a fractional marketplace, describes a fractional executive as having 16 to 24 hours where a full time executive has 40 (Fractionus, June 2026).

The number matters less than the shape. Three rules I hold every engagement to:

Fixed days, not a bank of hours. Tuesday and Thursday, every week. The team learns when the person is in. A floating bank of hours turns into email answered at night and meetings nobody can plan around.

In the room for the rhythm. The fractional executive attends the weekly leadership meeting and the monthly review, the same as anyone else on the team. Amy Bonsall, a fractional chief product officer, makes the same point on the HBR episode: include them in the key leadership touchpoints. A seat that only shows up for its own meetings never becomes part of the team.

Reachable between days, within reason. A short window on off days for decisions that cannot wait. Not an on call line.

When the work needs more than three days, it is no longer a fractional seat. That is an interim role or a full time hire, and a good fractional executive will say so in month one.

What the retainer looks like in the market

Fractional work is almost always priced as a monthly retainer for an agreed number of days, not by the hour. Leaders ADAPT quotes per engagement after the first call, so the numbers below are market figures from other firms, each with its source and date.

What moves the number: days per week, company size, whether a sale or raise is in the window, and whether the person brings an analyst or a team behind them. Our fractional executive cost page compares the seats side by side.

One thing a retainer should never be is a blank check. A retainer buys a fixed share of the week pointed at written outcomes. If the outcomes are not written down, the retainer drifts toward whatever is loudest that week.

The 90 day plan, month by month

Every engagement I run has a 90 day plan agreed in the first two weeks. It changes as we learn, but it exists, it is one page, and the owner signs off on it. This is roughly how the three months go.

Month one. Learn the company and earn the right to change it. The executive meets every direct report one on one, reads the last twelve months of numbers, sits in every recurring meeting, and writes down what they see. By day 30 the owner gets a short written read: what is working, what is broken, and the three things worth fixing first. Nothing structural changes yet. A fractional executive who reorganises your team in week two is guessing.

Month two. Fix the first thing and build the rhythm. Pick the highest value item from the day 30 read and fix it in the open. At the same time, install the cadence the seat will run on: a weekly scorecard, a standing slot in the leadership meeting, a monthly review with the owner. If the company does not have a weekly scorecard, building one is often the first real deliverable.

Month three. Hand work to the team and test it. The executive starts moving decisions to the people who should own them and watches what comes back. By day 90 the owner should see one outcome moving, one process running without the executive in the room, and a written plan for months four to six. If none of that is true, we talk about it plainly at the 90 day review, including whether to stop.

Reporting cadence

Bonsall describes holding an accountability session with the CEO at least once a week. I agree, and I keep it short. The cadence that works for owners I advise:

• Weekly, 30 minutes. Owner and executive. What moved, what is stuck, what the owner needs to decide.
• Monthly, one page. The scorecard against the two or three written outcomes, plus one risk.
• Quarterly review. Owner, executive and me. Keep, change scope, or end. KORE1 makes the same point from the staffing side: fractional work is open ended and should be reviewed quarterly.

Scope creep is the biggest risk in the reporting rhythm. Bonsall calls it absolutely an issue. The weekly check in is where you catch it, by asking whether this week's work still serves the written outcomes.

Notice, the exit clause and the handoff

The contract should say how the engagement ends before it starts.

Term and review. KORE1 and Fractionus both put typical fractional engagements at 6 to 18 months. KORE1 suggests that anything running past 18 months needs a written review date. I put the first formal review at 90 days and the next ones quarterly.

Notice. Fractionus notes that many consulting agreements default to 30 day termination, argues that 30 days is too short for executive work, and suggests 90 days with milestone based exit provisions so either side can leave early if agreed outcomes are missed. Whatever you choose, build the transition into the notice period or pay for it separately. The worst ending is a fractional executive who leaves on a Friday with the only copy of the plan in their head.

Who owns the work. The plan, the scorecard, the process documents and the models built for your company belong to your company. Write that in.

Contractor, not employee. Most fractional executives work as independent contractors. The label in the contract does not settle that. The IRS looks at three categories of evidence: behavioral control, financial control and the relationship of the parties. A part timer who works set hours under your direction, with benefits and no end date, starts to look like an employee. Talk to your accountant, and the IRS page explains how to request a ruling with Form SS-8.

The handoff to a full time hire. KORE1 reports that roughly a third of its fractional placements convert to full time roles. More often in companies between $5M and $50M, the better ending is that the fractional executive builds the seat, writes the job, interviews the candidates with you, and overlaps with the new hire for a month. The signs it is time: decisions in that seat arrive daily, the team in that function needs daily leadership, or the retainer is creeping toward a full salary for the same scope.

Where AI fits in a fractional engagement

AI makes a fractional seat more useful per day, in three places.

Preparation. The executive can walk into Tuesday having already read the week's numbers, the meeting notes and the pipeline changes, summarised and compared against last month. Days in the building go to decisions, not catching up.

Documentation. The day 30 read, the process notes and the handoff file can be drafted with an AI assistant from the executive's own notes. The handoff stops being a heroic final week.

Company knowledge. When the seat ends, the reasoning behind the decisions should stay. We build company knowledge systems for exactly this, and for owners running an EOS style rhythm our guide to AI for EOS companies shows where it sits in the quarterly cycle.

It does not belong in the judgment calls. Who to promote, which customer to let go, whether the plan is working. Our page on what not to delegate to AI goes deeper. AI can make a two day week feel like three. It cannot make the call that the executive was hired to make with you.

What a fractional engagement does not fix

I say this on the first call because it saves a year.

A fractional executive does not fix an owner who will not let go. If every decision still routes back to you, the executive will spend their days waiting for your answer, and you will pay a senior rate for a messenger. The delegation boomerang is a leadership problem before it is a staffing one.

It does not fix a leadership team that cannot run a meeting without you. A part time leader can model the rhythm, but the team has to own it. That is the work of leadership team development, and it is why I pair most fractional seats with work on the owner and the team.

It does not fix vague scope. If you cannot write the two or three outcomes, no contract will save the engagement. Write them first.

It does not replace the people who do the daily work. A fractional CFO is not a bookkeeper, and a fractional COO is not a shift manager.

Who is on the bench across the seats

The executives below are partners I bring in through Leaders ADAPT. Each one works inside the cadence above.

Steve Shaw sits in the CFO seat. He has twenty years in finance leadership and works on clean books, cash discipline and the numbers a lender or buyer will test. When the operating problem is really a finance problem, cash, margin, pricing, Steve takes the COO seat too. More on that seat at fractional CFO.

Chris Geddes and Marina St. Cyr cover the COO seat from two angles. Chris is an operator who pairs operations leadership with AI transformation. Marina is detail strong and runs the cadence and the follow through. See fractional COO.

Sergey Dmitriev takes the CTO seat and leads our AI systems work. He builds the data and knowledge systems we deliver and trains leadership teams on AI tools alongside me.

Steve Prodger is the fractional Chief Revenue Officer, for owners whose pipeline only moves when they sell. See fractional CRO.

Thor Legvold is the leadership psychologist. He works on executive fit and team dynamics, which matters most at the match and again at the handoff to a full time hire.

The full list of seats is on fractional executive services. The product page for the offer is Fractional Executives and Advisory.

Fractional Executive Engagement FAQ

How does a fractional executive engagement work?

A senior executive joins your company for a fixed share of the week, usually one to three days, on a monthly retainer. You agree two or three written outcomes, a 90 day plan, a weekly check in with the owner and a monthly scorecard. The contract names a notice period and a review date. Most engagements run six to eighteen months and end with a handoff.

How many days a week does a fractional executive work?

Most work one to three days a week. KORE1 puts typical fractional hours at 8 to 20 a week, and Fractionus describes 16 to 24 hours as common. The right number depends on how much of the problem needs a person in the room. Fixed days, such as Tuesdays and Thursdays, work better than a floating bank of hours that leaks into email.

What does a fractional executive retainer cost?

Published market figures for a fractional CFO retainer run from about $5,000 to $15,000 a month in KORE1's 2026 pages, with transaction work at the top of the band. Other seats sit in a similar range depending on days per week and company size. Leaders ADAPT does not publish prices and quotes each engagement after the first call.

What notice period should a fractional executive contract have?

Many consulting agreements default to 30 days. Fractionus argues that 30 days is too short for executive work and suggests 90 days, with milestone based exit rights so either side can leave early if agreed outcomes are missed. Whatever you choose, write the handoff into the notice period so the work does not walk out with the person.

Is a fractional executive an employee or a contractor?

Usually a contractor, but the label on the contract does not decide it. The IRS looks at behavioral control, financial control and the relationship of the parties. If a fractional executive works set hours under your direction with benefits and no end date, the facts start to look like employment. Ask your accountant, and file Form SS-8 if you need a ruling.

How long does a fractional executive engagement last?

KORE1 and Fractionus both put typical fractional engagements at 6 to 18 months, often with options to extend. The first 90 days build the plan and the cadence, the middle months run it, and the last months hand the seat to a team member or a full time hire. An engagement past 18 months without a written review date is drifting.

Can a fractional executive become a full time hire?

Sometimes. KORE1 reports that roughly a third of its fractional placements convert to full time roles. More often the better outcome is that the fractional executive builds the seat, writes the job, and helps you hire the permanent person. Agree in the contract how a conversion would work, so nobody feels ambushed when the question comes up.

Write the three outcomes before the first call

The single best predictor of a good fractional engagement is whether the owner can say, in one sentence each, what has to be different in six months. Not a role. Not a title. An outcome.

Tomorrow morning, before you open email, write three lines. What should be true in six months that is not true now. Who on your team should own it after. What you will stop doing once it is done. If you can write all three, the engagement is half scoped. If you can only write the first, that is a useful thing to know too.
