Fractional CFO vs controller vs bookkeeper
A bookkeeper records transactions, a controller runs the close and the controls, and a fractional CFO leads strategy and judgment. Most funds need the controller and CFO layer above basic bookkeeping, and that is the layer this piece explains.
A bookkeeper keeps the books current, a controller owns the close, reconciliations, and controls, and a fractional CFO leads strategy, judgment, and provider orchestration. The three roles build on each other rather than substituting for one another.
Three roles, three jobs
| Role | What they own | When a fund needs it |
|---|---|---|
| Bookkeeper | Recording transactions and keeping the books current | From day one, for basic recordkeeping |
| Controller | The close, reconciliations, controls, and accurate reporting | When accuracy, the close, and capital accounts need to be dependable |
| Fractional CFO | Strategy, judgment, provider orchestration, and the LP relationship | When the judgment calls and coordination exceed what a GP wants to carry |
How they stack
The roles build on each other. A bookkeeper produces the raw record, a controller turns that record into an accurate and controlled close, and a fractional CFO sits above both, owning strategy, the reporting narrative, and the coordination of admin, bank, legal, tax, and audit. The controller layer is also what the auditors lean on: a controlled close with clean reconciliations is typically what makes the year-end audit routine instead of a scramble. Hiring only a bookkeeper leaves judgment and controls uncovered, while hiring a full-time CFO for a small fund spends senior money on work that is mostly recording and reconciliation.
The team model
Graph Advisors staffs the layer most funds actually need: a fractional CFO who runs point, backed by a controller with fund-administration depth, with engineering when a process is worth automating. The fund gets judgment and execution depth without carrying a full-time salary, and without the risk that comes with depending on one person.

Frequently asked questions
What is the difference between a controller and a CFO?
A controller owns accurate accounting, meaning the close, reconciliations, and controls, while a CFO owns strategy, judgment, provider orchestration, and the LP relationship. Put simply, the controller makes sure the numbers are right and the CFO decides what to do with them.
Do I need a bookkeeper, a controller, or a CFO for my fund?
Most funds need all three functions, though rarely as three full-time hires. The most common gap is the controller and CFO layer above basic bookkeeping, and that layer is what a fractional team is built to cover.
Can one person do all three roles?
At a small fund one person may stretch across all three for a while, but that concentrates risk and usually means the strategic and control work gets less attention than it needs. A team can split recording, controls, and judgment so each is properly covered.
What does a fractional CFO add over a controller?
A fractional CFO adds strategy and judgment on top of the controller's accurate close: capital call and distribution timing, the LP reporting narrative, and coordination of admin, legal, tax, and audit.
How does Graph Advisors staff finance for a fund?
