Very well written and relevant article. I also believe that the market (clients) are going to look more and more to practicinors who provide fixed-fee accounting services.
CPAs work with their clients up front to determine what services they will need and they know exactly what services they will receive.
Services, fees and payments normally are set in stone which means the client knows upfront how much they need to pay which allows them to plan workflows around known commitments.
The client knows when they need to pay (for monthly fee arrangements).
It allows for the clients to be more open to discussing issues that come up with their business, which can prevent problems.
Their are surprise bills at the end of the assignment.
With no bills to haggle over, clients are less apprehensive about seeing their accountant.
