Fractional vs interim vs consultant: the real difference
A consultant advises and exits. A fractional executive owns a function. An interim manager operates a seat temporarily.
In short
A fractional executive is part-time and ongoing, giving you senior leadership a few days a week. An interim executive is full-time and temporary, taking the wheel for a fixed period such as a gap or a crisis. A consultant advises and recommends but does not own the outcome or run the team. Choose fractional for continuous senior leadership on a budget, interim for a full-time gap or crisis, and a consultant when you need an expert opinion rather than an operator in the seat.
The direct answer
All three put senior expertise into your business without a permanent hire, but they differ on two axes: how much time they give you, and whether they own the outcome. A fractional executive is part-time and continuous and owns a number. An interim is full-time and finite and owns the whole seat. A consultant is project-based and owns a recommendation, not the result.
How they compare
| Dimension | Fractional | Interim | Consultant |
|---|---|---|---|
| Time | Part-time, ongoing | Full-time, fixed term | Project-based |
| Role | Owns a function or number | Runs the whole seat | Advises and recommends |
| Accountability | For results, continuously | For results, until handover | For the deliverable |
| Typical duration | Rolling, months to years | 6 to 12 months | Weeks to a few months |
| Typical cost | EUR 4,000 to 15,000 / month | EUR 18,000 to 45,000 / month | EUR 1,500 to 3,000 / day |
| Best fit | SME or scale-up needing senior leadership | Gap, crisis or transition | Specific expert question |
The lines blur in practice. We often start fractional and step up to interim when a situation escalates.
When to choose a fractional executive
Choose fractional when you need executive judgement and ownership continuously but cannot justify a full-time hire. The fractional operator sets direction, builds the operating rhythm, owns a number such as revenue or CAC, and mentors the team a few days a week, scaling time up or down as you grow.
When to choose an interim executive
Choose interim when the seat is empty or on fire and you need someone in command full-time, today. The interim takes the wheel completely, stabilises the business or delivers the transition, then hands over cleanly to a permanent hire.
When a consultant is the right call
Choose a consultant when you need an expert opinion, a diagnosis, or a plan, but your own team will execute. A consultant is the right tool for a discrete question. They are the wrong tool when the problem is execution, accountability or leadership: that is what an operator in the seat is for.
A simple decision framework
Ask two questions. First, do you need someone full-time or part-time? Second, do you need them to own the outcome or just advise on it? Full-time plus ownership points to interim. Part-time plus ownership points to fractional. Advice without ownership points to a consultant.

Frequently asked questions
Is a fractional executive the same as a consultant?
No. A consultant advises and recommends; a fractional executive sits inside your business part-time, owns a number and runs the work. One gives an opinion, the other delivers the result.
What is the difference between interim and fractional?
Interim is full-time and temporary, filling a gap or running a crisis. Fractional is part-time and ongoing, giving senior leadership a few days a week. Same calibre of operator, different time and intent.
Which is cheapest?
On a monthly basis a consultant or a light fractional engagement costs least, but a consultant does not run the business. For ongoing leadership a fractional executive is the most cost-effective; for a full-time gap an interim is the right spend.
Can you switch between them?
Yes. We often begin as a fractional executive and step up to a full-time interim role when a situation escalates, then scale back down once it is stable.
Fractional vs interim executive: which do I need?
Choose a fractional executive when you need senior leadership on an ongoing, part-time basis, a few days a week, to steer a function without a full-time salary. Choose an interim executive when you need someone full-time to fill a vacant seat or run a crisis for a fixed period. Same calibre of operator; fractional is continuity on a budget, interim is full ownership of a gap.
