Why does Aha Planner ask for fewer numbers than my financial statements have?

Aha Planner asks for a shorter list of numbers than a full set of financial statements carries. Detailed operating costs fold into one Total Operating Expense, accumulated depreciation and gross property fold into one net Total Fixed Assets, and your cash flow statement, equity, capital expenditure, and income tax are all worked out for you. The lines a valuation has to normalize, such as non-recurring revenue and executive compensation, are asked for separately.
