Inside Sales

Inside sales generally involves attempting to close business primarily over the phone via cold calling or telemarketing, while outside sales (or "field" sales) will usually involve initial phone work to book sales calls at the potential buyer's location to attempt to close the deal in person. Some companies have an inside sales department that works with outside representatives and book their appointments for them. Inside sales sometimes refers to upselling to existing customers.
