SFASales Force Automation
SFA is software that automates repetitive steps in selling - lead allocation, activity capture, follow-up scheduling, approvals and performance reporting - so that field and inside sales teams spend more time with customers.
CRM records the relationship; SFA drives the next action and confirms it happened.
In pharma, SFA usually refers specifically to the medical representative's call reporting, tour planning and coverage-frequency system.
