An inside sales representative is a sales professional who conducts sales online or over the phone. A career in inside sales is very similar to outside sales job model. You are responsible for developing and maintaining client relationships based on leads, and your compensation is usually based on commission. Since relationships are developed virtually, rather than in person, the position requires a unique set of skills一these include a high level of computer proficiency, phone skills, and the ability to build rapport during client calls without the benefit of face to face interaction.
