Direct selling and personal selling are the different types of business models used by the business. Direct selling is the distribution of products and services through independent distributors. Usually, product demos are consulted in home parties, workplaces, or other non-store locations. There are different types of direct selling such as single level marketing, multi-level marketing, home parties, online direct selling.  Here they leverage networks of independent salespeople to broaden market reach. 

Personal selling is a sales technique where products are sold through face-to-face interaction which focuses on relationship building. Here the customer interaction is done through formal meetings, presentations and negotiations. Here the salespeople are often recruited as company employees. Customers are followed up through emails, calls and meetings. Here they focus more on deepening existing customer relationships rather than broad market expansion.
