There are really only 3 main differences between a part-time and interim CFO:
- Companies that engage an interim CFO are generally larger than companies with a part-time CFO
- An interim CFO is usually hired when there is an unexpected departure by the previous full-time CFO or other senior finance personnel
- An interim CFO normally works for the company on a full-time basis until a new full-time CFO can be hired
Other than that we have found the approach we use works in either situation
