Field service management software (or FSM) is a solution that focuses on field centered activities like tracking deliveries, scheduling, and asset management. On the other hand, route accounting software falls more in the realm of Enterprise Resource Planning (ERP) which is designed to streamline and automate systems to save you time around accounting, management, and supply chain field services and operations. The main difference is that FSM targets more field service technicians and people that work in the field, whereas ERP is more for the admin dimension of businesses.
