Fractional vs. Full-Time: Staffing Decisions in the First Year After Acquisition

Not every leadership gap after an acquisition needs a full-time hire right away — but knowing which ones can wait, and which can't, is where a lot of new owners guess wrong.

When fractional makes sense

Fractional leadership — a part-time CFO, a part-time COO — works well when the function needs senior judgment on a recurring basis but not full-time attention: financial reporting and forecasting for a business under $10M in revenue, for instance, or operational oversight while a general manager is being recruited. It's also a reasonable bridge while a full-time search is underway, so the role isn't going unfilled for months.

Fractional leadership works poorly when the role needs to be present for day-to-day decisions, when the team needs a consistent point of authority, or when the function is central to the deal thesis. A fractional head of sales, for example, rarely works for a business whose growth plan depends on an aggressive, hands-on sales leader.

A simple test

One useful test: does this role need to make decisions other people are waiting on, in real time, more than a few times a week? If yes, it needs to be full-time. If the role is mostly forward-looking — planning, reporting, strategic input — fractional can genuinely work, sometimes permanently.

Function by function

The test above applies differently across the leadership team.

• Finance: often suits a fractional leader early on, supported by a capable bookkeeper or controller. Move to full-time when reporting, lender requirements or a second acquisition make it a daily job.
• Operations: usually full-time. The people doing the work need someone present who can decide.
• Sales: full-time where growth is the plan. A part-time sales leader can coach, but cannot carry a number.
• HR: frequently fractional or outsourced in a smaller business, with a full-time hire as headcount grows.

Moving from fractional to full-time

A fractional arrangement should have an end condition agreed at the start: a revenue level, a headcount, or an event such as a refinancing. Without one, a temporary answer becomes permanent by default. Where the fractional leader is a candidate for the full-time role, say so early. Where they are not, ask them to help define the role and assess candidates, since they know the job better than anyone.

NaviTrust helps investors and acquisition entrepreneurs decide which roles to fill and recruits for the ones that need a permanent leader. See also Building Your Leadership Bench as a Solo Operator.

The businesses that get this wrong tend to make the decision based on budget alone, defaulting to fractional everywhere to control costs in year one. That often means the roles that most need consistent, present leadership are the ones being staffed the thinnest. Matching the staffing model to what the role actually requires — not just what it costs — is what keeps a newly acquired business from stalling in its first year.
