SFA stands for Sales Force Outsourcing automation software. SFA is a type of program that automates business tasks such as inventory control, sales processing and tracking of customer interactions as well as analyzing sales forecasts and performance. SFA software is a solution that helps field-based teams do their job more effectively. It is called Sales Force Outsourcing Automation software because sales teams were the first and are still the largest set of users for this type of software, but there are other types of teams such as visual merchandisers, BTL marketers, service and support teams and many others who also use software with similar functionality. SFA packages typically include a Web-ready database, an e-mail package and customizable templates. A three-tiered architecture is typically used to separate the database, server and application to reduce programming demands on clients. A module-based design is generally used to allow users to customize the package to suit their needs.
