Fractional engagements are designed to end. Almost none of them are designed for ending, which is why so many companies discover six weeks later that nobody knows why the budget is allocated the way it is.
An ending is not a failure signal. The good version arrives on schedule: the company has grown into a full-time hire, or the specific problem the engagement existed to solve has been solved. The bad version is not that it ended — it is that it ended without a handoff, and the institutional memory walked out with the contractor.
What actually gets lost
The assets are rarely the problem. Files, accounts and campaigns are transferable and usually do transfer. What disappears is the reasoning: why this channel and not that one, what was tried and abandoned, which audience turned out not to convert, what the numbers mean, and which apparently sensible idea has already failed twice.
Without it, the successor repeats the experiments. Companies routinely fund the same failed test three times across three marketing leaders, each time treating it as a fresh idea. The cost of a bad handoff is not administrative — it is a year of relearning.
Build the handoff from the first month
A handoff assembled at the end is a memoir. A handoff maintained throughout is a record. The difference in accuracy is large, because nobody accurately reconstructs the reasoning behind a decision made seven months earlier under different assumptions.
The practical form is a single living document updated as decisions happen: what was decided, what it was based on, what would make us reverse it. That last clause is the valuable one and the one most often missing.
- Decisions taken, with the evidence available at the time and the condition that would reverse them
- Experiments run and stopped, with the result and why it was called
- Current channel economics — what a lead costs where, and how confident we are in that number
- Accounts, ownership and billing, including anything in the CMO's name that must be transferred
- Relationships: which contractors, which agencies, what each is contracted to do and how they are performing
- The next three things you would do, and why they are next
Transfer accounts early, not at the end
Anything created during the engagement should sit in the company's ownership from the day it is created — ad accounts, analytics, domains, tools, publishing access. This sounds obvious and is violated constantly, usually for convenience during setup and then never corrected.
The failure is expensive and entirely avoidable: an ad account with history sitting under a personal profile, a tool subscription on a contractor's card, a domain registered to whoever happened to buy it. Audit ownership at month one, not month eleven.
Overlap beats a clean break
Where a successor exists, a short overlap is worth far more than the days it costs. Two or three weeks of shared time transfers the tacit knowledge that no document holds — the reason a particular client relationship is delicate, the reason nobody touches a certain page, the history behind a supplier.
Where no successor exists yet, the equivalent is a genuinely detailed briefing for whoever holds the fort, plus a defined window in which questions can still be asked. An hour available for a month afterwards prevents an enormous amount of drift.
Ending early is sometimes correct
If the arrangement is not working, ending it promptly and cleanly is better for both sides than letting it decay into a fortnightly call nobody values. The same handoff discipline applies, and it applies more urgently, because a disappointing engagement still generated real information about what does not work for this company.
Treat the exit as a deliverable rather than an administrative event, and the next person starts from where this one finished instead of from the beginning.
