An SFA, typically a part of a company's CRM system, is a system that automatically records all the stages in a sales process. SFA includes a contact management system which tracks all contact that has been made with a given customer, the purpose of the contact, and any follow up that may be needed. This ensures that sales efforts are not duplicated, reducing the risk of irritating customers. SFA also includes a sales lead tracking system, which lists potential customers through paid phone lists, or customers of related products. Other elements of an SFA system can include sales forecasting, order management and product knowledge. More developed SFA systems have features where customers can actually model the product to meet their needs through online product building systems. This is becoming popular in the automobile industry, where patrons can customize various features such as color and interior features such as leather vs. upholstered seats.
