Why is it important for the operator to close a sale plan upon completion of a trip?

Closing a sale plan upon completion of a trip is crucial for several reasons. It ensures that all details are finalized and documented, preventing misunderstandings or disputes later on. This step also allows the operator to assess the trip's success, gather feedback, and make necessary adjustments for future trips. Additionally, it strengthens customer relationships by demonstrating professionalism and attention to detail.
