The Software Industry and IT Services Industry provides a vital and significant role for presales professionals. The role of presales falls right in the middle marrying the customer needs to the (provider) company's services or products. This role is especially crucial in these industries because the products and services are often heavily customizable and also because the requirements of different customers are often unique. The presales professional thus understands what the customer needs, develops an initial view of the solution the customer needs, then tailors the product or service of his company to meet what the customer needs, explains (or helps sell) this solution to the customer, helps close the deal or sale and often stays on to ensure that the delivery team or product specialists that follow him provide the intended solution.
