It clearly depends on the course level that you undertake. A basic business accounting course would include an understanding of what business accounting is and its need. The course would also teach you how to interpret financial sheets, understand basic technical terms in business accounting, how to prepare balance sheets, profit and loss analysis. An advanced-level accounting course would take the basic course a step further. It would involve topics like budgets, how to process orders, how to understand and analyze stock movement, accounting of inventory, etc.
