Final answer:
The tool used by firms for tracking internal sales and marketing information is the Customer Relationship Management (CRM) System, which helps manage customer relationships and track sales engagements.
Step-by-step explanation:
The tool used by firms to track information from within the organization to report on sales and marketing results is the Customer Relationship Management (CRM) System. This system is designed to manage and maintain customer relationships, track engagements and sales, and deliver actionable data—all in one place. Organizations use CRM systems to ensure that their marketing and sales efforts are effectively contributing to the growth of the business. Meanwhile, a Marketing Information System (MIS) is used to analyze and manage marketing information gathered from various sources. An Enterprise Resource Planning (ERP) System integrates all facets of an operation, including development, manufacturing, sales, and marketing.
Lastly, the Sales Force Automation (SFA) System is used specifically to automate sales tasks such as inventory control, sales processing, and tracking of customer interactions, but it does not offer the extensive reporting features of a CRM system.
