You must have heard the adage ‘cash is king’ and it is true for online business as well. Cash flow is an important component of success for such a business as it determines the new investments and market expansion. For an online business owner, it is mandatory to understand and track the cash flow. The crux of it is to see what amount of money is being brought into the business as compared to the amount that is going out. If the business requires more spending than earning, immediate changes have to be implemented to avoid going bankrupt.
