In simple terms, the purpose of a business is to make money (unless it is a non-profit or charitable organization), besides value addition to customers, realizing passion, helping people etc. If the business is not making money sooner or later, everything else will fade away. That is the hard reality. Period.
It is important that the money is managed well; especially for small bootstrapped business. As a business owner, at a minimum, you will need to watch the cashflow, oversee timesheets, billing and invoices and track payments.
