Fractional CMO vs marketing consultant: what's the difference?
Both are senior and both are part-time. The difference is who owns the result once the advice is given.
- Do we need a consultant or a fractional CMO?
- Isn't a fractional CMO just a consultant?
- Which is cheaper?
A marketing consultant advises on a defined problem for a set period and hands over recommendations. A fractional CMO owns marketing on an ongoing basis: they make decisions, direct the team and answer for the results. Choose a consultant for a one-off question, such as pricing or a launch plan. Choose a fractional CMO when you need someone accountable every week.
| Marketing consultant | Fractional CMO | |
|---|---|---|
| Engagement | Project, often 4 to 12 weeks | Ongoing, usually 6 months or more |
| Owns | The quality of the advice | The decisions and the marketing number |
| Deliverable | Report, plan or workshop | Running plan, team direction, monthly results |
| Works with your team | Sometimes, as an advisor | Every week, as their leader |
| Best for | A specific question you can define | Ongoing leadership you don't have yet |
The test we use
Ask what happens on the day after the engagement ends. If the answer is that your team executes a plan they understand, a consultant is enough. If the answer is that nobody owns the plan, you need ongoing leadership.
Combining the two
Some companies start with a short consulting project, such as positioning or a channel audit, and extend it into a fractional role if the fit is good. That is a sensible way to test the working relationship before a longer contract.
- A consultant expected to own results after the report is delivered.
- A fractional CMO with no ongoing authority over the team.
- An open-ended consulting retainer with no deliverable.
- Recommendations nobody on your team can execute.
- Paying for both to solve the same problem.
- A defined question for a consultant, with a fixed end date.
- A named owner for executing the advice.
- Decision rights written down for a fractional CMO.
- A short paid project first to test fit.
- Monthly results reviews for ongoing roles.
