The Pros of an Ecommerce Business Model Cost One of the huge benefits of an ecommerce business is that there are no traditional retail costs. These businesses reduce the cost of the physical location, something which often ends up costing the business owner thousands of dollars per month in rent alone. You also do not need to have any cashiers or clerks on staff, so your payroll costs become very limited –– or even zero –– as many ecommerce businesses are completely owner-operated without a single full-time employee.
