Careers in sales include both inside and outside sales personnel. The primary responsibilities of inside salespeople often include finding new customers, new leads for potential business and meeting with leads to set business up. A career in sales is focused on consumers and how they are treated by the salespeople. A good realtionship with your customer through the entire sale leads to more customers coming your way through referrals. Sales is usually refferal based and when you gain loyal customers, they send others your way.
