What makes the difference between a sales manager and a regular sales officer?

Sales Manager or even a Director is usually one person in charge of a team of sales people, he/she will make sure that the team is hitting targets etc. A Sales Officer should be part of his team, I think an officer is more of a high flyer than say a sales person in a retail store and would be visiing corporate clients.

Sales manager sets a plan and Sales officer follow but they must work together step by step as a team to make sure that plan is implemented.

the basic difference is hierarchy or position level. example, a sales Officer will report to the sales manager. the sales executive has a lower position level vs the sales manager. in some industries, example, in pharma the sales Officer will report to a field manager who in turn reports to the sales manager
