Review the retainer when actual work differs materially from scope, the team gains or loses capacity, the constraint changes or decisions are waiting too long. Document what to add, remove or delegate and how success will be judged. More hours are not always the answer; sometimes the company needs a maker or a permanent leader.
Compare the agreement with the calendar
Look at the work promised, work done, decisions delayed and unplanned demands. A role that began as positioning advice may now involve managing three people and an agency. Or the first strategic decisions may be complete and the remaining need is hands-on production. The services scope guide helps name the difference.
Diagnose the limiting resource
Ask whether the bottleneck is senior judgment, maker capacity, founder approvals or a product or sales dependency. If the CMO makes decisions promptly but assets do not ship, adding CMO hours may be wasteful. If the team can execute but waits for strategic tradeoffs, more leader availability may help. If decisions require daily ownership across a growing team, a full-time hire may be the right next step.
Write a change order
State what is added, removed and no longer expected, the fee or time effect, new authority and the next review date. Keep the original business goal visible. Scope drift often feels like underperformance because nobody acknowledges that the job changed. A short written reset protects both founder and leader.
A bounded example
A hypothetical company hires a fractional CMO to fix messaging. Six months later it has a strong message but needs constant campaign production. Rather than extending the same retainer and hoping for more output, it may keep light strategic review and hire a marketer. Another company may see the opposite: enough makers, too many unresolved cross-functional decisions. Rescope against that actual constraint.
Four signals that the scope has moved
Watch for a consistent queue of decisions waiting beyond the leader's availability, recurring production work that was never in the agreement, new people requiring management or a changed business objective. Compare each with the original scope and the last four weeks of work. Do not rely only on a vague feeling that the provider is “less responsive”; ask which decision was delayed and what it affected.
At the rescope meeting, choose one of four actions: remove lower-value work, add leadership time, add a maker or plan a permanent handoff. Write the tradeoff and next review date. A new product launch may justify a temporary increase; a mature channel may justify less senior time. If the same disagreement recurs despite clear terms, the working relationship or authority may be the problem. Retainers should adapt to the job, but each change must be explicit enough that both sides can judge it fairly.
Frequently asked questions
How often should a retainer scope be reviewed?
Set a regular review cadence and revisit it sooner after major changes such as a new product, hire, funding event or channel shift.
Should the founder simply buy more fractional hours?
Only if senior decision capacity is the bottleneck. If production or approvals are blocking progress, extra leadership hours may not help.
Is the current fractional arrangement no longer matching the work?
Bring the original scope and recent decision log. We can identify whether to narrow, expand or hand over the role.
