Permanent vs Interim vs Fractional CRO

Once a business accepts it genuinely needs CRO-level leadership, the next decision is often treated as secondary when it is not: which engagement model actually fits the situation. Getting this wrong wastes money in one direction and leaves the underlying revenue fragmentation unresolved in the other.

The three models solve different problems. Matching the model to the trigger, rather than to convenience or cost alone, is what makes the appointment work.

Start with the trigger, not the budget

Budget matters, but deciding on cost first tends to produce a model that fits the invoice rather than the problem. The more reliable starting point is the trigger: why is this conversation happening now? A sudden departure, a stalled fundraise, an acquisition to integrate, or a slow-burning realisation that sales, marketing and success no longer function as one system each point towards a different model.

Permanent: for lasting structural complexity

A permanent CRO is the right model where the fragmentation across revenue functions is not a phase the business will grow out of — it is the shape of the business going forward. This is typical of scaling B2B and SaaS businesses with material recurring revenue, multiple go-to-market motions, or investor expectations of continuous, board-credible revenue ownership.

Permanent appointments justify the time and cost of a full search process because the role is not being asked to fix a moment — it is being asked to run a system indefinitely.

Interim: for a defined period and a defined mandate

An interim CRO is not a slower or cheaper version of a permanent one. It is a different kind of appointment: someone who can walk into a specific mandate — stabilise the forecast, integrate two revenue functions post-acquisition, hold the seat during a search, prepare the revenue story for investors — and be judged on delivering that mandate within an agreed period.

An interim CRO succeeds by finishing the mandate, not by staying. Confusing the two is the most common reason interim engagements overrun without adding value.

• Departure cover while a considered permanent search runs, rather than a rushed permanent hire
• Pre-fundraise or pre-exit readiness — clean, defensible revenue reporting and a credible growth narrative
• Post-acquisition integration of separate sales, marketing or customer success functions
• Turnaround where the forecast has lost board credibility and needs rebuilding on a trustworthy basis

Fractional: for direction without full-time need

A fractional CRO provides the cross-function thinking — revenue strategy, alignment between sales, marketing and success, forecast discipline, pricing input — for a part of the working week, typically where full-time scale is not yet justified but the fragmentation the role exists to solve is already real. Day-to-day management of each function usually still sits with function heads or a Sales Director; the fractional CRO sets direction, standards and the connective structure between them.

This is a distinct engagement from a business hiring a fractional executive on an ongoing basis to run its commercial function day to day — the fractional CRO model assumes existing function leadership that needs unifying, not a business with no senior commercial leadership at all.

What does not change between models

The core areas of ownership — the combined revenue plan, alignment across sales, marketing and success, revenue operations standards, and the company-level forecast — do not shrink because the engagement is interim or fractional. What changes is time horizon, depth of day-to-day involvement, and the specificity of the mandate. A fractional or interim CRO with a vague brief fails for the same reason a permanent one does: undefined ownership.

Cost shape, not just cost level

Permanent cost is ongoing and typically includes bonus or incentive structures tied to revenue performance. Interim cost is time-bound and priced for a defined mandate, often at a premium reflecting immediate availability and accountability without notice-period protection. Fractional cost scales with days engaged and is usually the lowest absolute monthly cost of the three — but only represents value where the mandate genuinely fits a part-time cadence. Indicative UK figures across all three models are set out in the UK Executive Salary Guide.

Moving between models

It is common, and often sensible, to move between models as the situation clarifies — starting fractional while assessing whether full-time revenue leadership is genuinely warranted, or starting interim while running a considered permanent search rather than rushing a permanent decision under pressure. The mistake is treating the first model chosen as a permanent commitment to that model rather than a considered response to where the business is now.
