What is meant by inhouse market?

In-house market is a type of non-traditional market where door-to-door salespersons visit the homes of consumers and offer products to them. Initial contact may be created through telephone or mailed-in coupons before the visit. In India, Eureka Forbes sells its water filters and vacuum cleaners through this method. Sometimes, a host invites friends to a party where the salesperson demonstrates the products and takes orders.
