Frequently asked questions

Can one person do both?
At a smaller scale, yes — for a brand under £3m of revenue, a single fractional finance leader can wear both hats. Above that, separating the roles produces better outcomes. The skill sets diverge.
Is an outsourced FD cheaper than a fractional CFO?
Per hour, roughly similar. Per engagement, an outsourced FD typically costs more in monthly retainer because the time commitment is higher.
