Just because someone has an accounting degree does not mean that they will have reached a level of expertise that justifies them making big picture decisions in some way, shape or form. A big part of the reason why that is the case has to do with the fact that you need to have someone that has a bit more expertise and technical knowledge if you want to hire them for such things at any given point in time, and the best people for those kinds of jobs are chartered accountants.
A chartered accountant, or a Chicago CPA as they are called in the US, are basically the supreme leaders of the accounting profession. They provide a wide range of services including financial management, auditing as well as taxation calculation. Most of their customers tend to be in the corporate sector but they also have a fair number of regular people that hire them too, and suffice it to say that they help these people obtain more control over the money that they might have in their possession.
Another thing that you should know about chartered accountants is that they are essentially all part of one big club. The charter in question is something that they all need to follow through with as they move along their career path, and if they do anything that is deemed to be irregular or unprofessional they can be summarily ejected from these organizations as well. That means that the stakes are a lot higher for them which entices them into doing better work for their clients and maintaining a much higher standard of professionalism than regular accountants that you might come across out there.
