Answer:
This type of salesperson is referred to as a order getter.
Step-by-step explanation:
An order getter is the salesperson that mostly fits the description given in the question. An order getter goes out to meet prospective clients, convinces them that the product is best to solve their business needs and also helps with post-sales activities.
In comparison, an inside order takes sales orders and is not required to be the one making sales. Also, an order clerk receives customer orders and handles payments.
A consultant could also perform the tasks mentioned in the question but his duties could go beyond that and would require more experience and skill across a wider region.
