Hi There,
Sometimes it is hard to trust anyone with the finances, so you keep doing the work yourself even when it becomes burdensome. It happened to me when I was managing accounting and bookkeeping while running my business. It was becoming difficult to concentrate on my business strategy and sales, since I was always neck deep in the financial admin work. I was not willing to give the responsibility to any rookie, so I kept doing it myself. One day, I sat down to understand how it affected my business and I was dumbfounded by the time I was wasting on it. Here is an article that will outline it for you and give you the advice you need.
