Knowing your costs is paramount, ALL YOUR COSTS. You can not correctly gain profit without knowing this. The taxman will asses your profit, and he will take a proportion of it. If you do not keep a handle on your costs, this assessment by the tax man may be bad for you as they will take more money, and it is hard to dispute once the taxman has made an assessment.
Costs
Costs can be broken into two distinct groups. The first group is the general costs, also known as overheads. This could include heating, lighting etc. Te second group is project costs, which will be the costs related to a specific project. You will have to take into account the time on the project etc.
