Sales quantity or sales quality

Across industries we come across sales professionals who admit to have forced a sale only to add a number to the board without conviction that the product sold is of value to the customer. This is spoiling the market and also bringing disrepute to a salesman's profession.  Sales team members close a deal and move to the next without actually following up whether the client is totally satisfied with the sale, customers are left without any support to iron out post purchase dissonance, thanks to this number game and needless to say after a point a sales guy cannot be blamed as he is just doing his job to survive the competition. However I strongly believe that this trend ought to see a reversal, the life time value of a cmr can be enhanced if seamless service is made available by the sales RM to the client and perfect hand holding is done, and for this due credit goes to the RM, even if the RM  closes 2 deals less in the long run a Quality Sale would be more profitable. Its important that the sales team be motivated and encouraged to look at quality sales as  a happy customer  will lead to a happy company and a happy company will ensure happy employees.
