The software should be capable of computing major accounting ratios
Different people believe in analyzing or monitoring different ratios, as well as a wide range of other metrics. What is important to someone else might not be what you want to look at, and vice versa. You have all data necessary to calculate ratios. The program focuses on accounting rather than analysis.
I dont think that is a good answer!
Then you should propose something specific, including definitions of the ratios you recommend, how and where they would be accessed, how they would be handled when switching from cash to accrual accounting, and what would be done if a user has not enabled features required to generate data necessary to calculate your particular ratios.
