Field sales are sales activities that involve direct face-to-face communication with customers. At times called outside sales because it involves going out into the field.
Sometimes it is difficult to convey the merits of a service/product by phone, DM, or email and there is a need to carry out sales activities by actually meeting with the customer.
CRTM actually accompanies clients on their sales visits to better understand the customer's needs, build a relationship with them and propose solutions.
