I just want to add to this that accounting is extremely figured out in a lot of ways, and so learning it well will help you run your business better even if you are not doing the grunt labour. If you understand the ebbs and flows and trends of your particular business it is inevitably going to be tied to the concrete accounting data- economics is the same way. It tries to take the concrete and extract trends from it to understand how stuff works. If you are also working on a B2B sort of operation, accounting is part of the lingua franca. If you are completely naive to it you will be surely less off.
