Sales calls are normally a matter of numbers, meaning that more calls will result in more leads and sales. The moment after the first outreach has been performed, closing the sale can be controlled by the internal sales force.
A brilliant salesperson’s skills and expertise can be efficiently utilized to handle customers and close sales, rather than just make cold calls. It might also be more effective to outsource customer support compared to maintaining a qualified support staff to handle these tasks. This is especially true for product – based companies.
