Inside sales refers to a business model where salespeople conduct their sales activities remotely, often over the phone or internet. This approach allows for a larger reach and the ability to communicate with potential clients from anywhere in the world. It also offers cost savings for companies, as they do not need physical office space for their sales team. However, building personal connections with prospects can be more challenging in an inside sales approach. Ultimately, whether a company chooses inside or outside sales will depend on their specific industry and target market preferences.
