Permanent vs Interim vs Fractional Head of Sales

The engagement model question usually gets asked after the role has already been defined, which is backwards. The right model — permanent, interim or fractional — depends on the nature of the problem, and answering it early saves a recruitment process that starts down the wrong path entirely.

Each model suits a genuinely different situation. None is a cheaper or lesser version of the others; they solve different problems.

Start from the problem, not the budget

It is tempting to treat fractional as simply the cheaper option and permanent as the 'proper' one. That framing causes bad decisions. A fractional appointment into a fifteen-person sales team needing daily coaching will fail regardless of the quality of the person, because the problem needs more hours than the model provides. Match the model to the problem first, then discuss cost.

Permanent: for an ongoing, stable requirement

A permanent appointment makes sense once the management need is not going to shrink — the team is established, growing, and the business is committing to sales as an ongoing structured function rather than treating it as a temporary problem to be solved. Permanent appointments justify a longer, more thorough process, because the cost of a wrong hire compounds over years rather than months.

Interim: for a defined, urgent gap

Interim Head of Sales appointments typically follow a sudden departure, cover parental or long-term leave, or stabilise a team through a period of change — a restructure, an acquisition, or a difficult quarter that needs firm hands quickly. An interim appointment usually arrives faster than a permanent search and works to an explicit, time-bound mandate agreed at the outset.

• Speed of appointment matters more than long-term culture fit
• The mandate is specific: stabilise, hold the line, or bridge to a permanent hire
• The interim is often given more direct authority to make fast performance decisions than a new permanent hire would be given in month one

Fractional: for partial need, or need not yet proven

A fractional Head of Sales works a set number of days per week, installing the structures — pipeline reviews, activity standards, coaching cadence, forecast discipline — that a small or early-stage team needs, without the business committing to a full-time salary before it is confident the requirement will last. This is a genuinely different proposition from Evans providing fractional commercial leadership directly; here the discussion is about recruiting a fractional Head of Sales into the client's own structure.

Fractional does not mean part of a full-time job done badly — it means a defined scope, done properly, within the time available.

The cost comparison is more nuanced than day rate

A day rate for interim or fractional cover often looks higher than an annualised permanent salary when compared crudely. The more useful comparison is total committed cost against the actual duration and intensity of the need — an interim covering a three-month gap, or a fractional appointment covering two days a week, frequently costs less overall than a rushed permanent hire made under time pressure that has to be replaced within a year.

Common mis-matches to avoid

1. 01Hiring permanently under time pressure when an interim would buy the time to run a proper search
2. 02Engaging fractional support for a team that genuinely needs daily, full-time coaching
3. 03Treating an interim appointment as a trial for a permanent role without agreeing that intention upfront
4. 04Assuming a fractional Head of Sales will also build commercial strategy — that sits with a Sales Director or Commercial Director

Can the model change mid-engagement?

Yes, and it often should. An interim appointment frequently converts to permanent once both sides see the fit is right. A fractional engagement frequently scales to more days, or to full-time, as the team grows. Agreeing at the outset whether conversion is on the table avoids an awkward conversation later and can shape how the search is run from day one.
