Fractional CFOs work a flexible number of hours based on the changing needs of the business they serve. This could be a few hours a month up to 10 or 20 hours a week.

Fractional CFOs are used to working flexibly and on-demand. This means that you may need them close to full-time for a few weeks before converting to a low number of hours for ongoing guidance. Your business may not need the full-time support of a CFO, but having fractional guidance to support your controller and advise your CEO can be an invaluable asset in creating company strategy.

A startup can benefit from the council of a seasoned industry CFO from day one, but realistically the startup won't have demands on their finance and accounting function that warrant the involvement of a CFO until they've raised seed capital. Preparing for future rounds of funding is just one of the many areas that a fractional CFO can add value to a startup.

A fortune 500 CFO may not make the best fit in a startup environment. Similarly, a fractional CFO with a background in telecommunications is unlikely to have the expertise needed in a healthcare organization. A CPA can be a great credential to find in a CFO, but not every company will need a CFO with a heavy background in accounting. Circumstances vary for each company depending on the stage and needs of the organization.

A fractional CFO's involvement depends greatly on the stage and needs of the organization. In smaller companies, the fractional CFO may personally take on a broad set of responsibilities, including managing the books, negotiating contracts, and more. In a larger company, the fractional CFO may oversee and guide the controller who manages the accounting function as well as other leaders in the finance function.
