Introduction
Property business is a type of business that is directly or indirectly related to the interests of many people. The community needs property products, especially housing to meet their basic needs. In the property business it can also help provide a place for business and long-term investment. In a company in general and more specifically in the property development business, Marketing plays an important role for conducting integrated communication aimed at providing information from the company to consumers about property goods offered. This is where it becomes important that there is a link between producers on the one hand and consumers on the other hand in order to bridge the information, so the role of marketing as information media becomes very important. This information media becomes important in order to achieve the objectives to meet the needs and desires of consumers. The development of information technology also penetrated into the sales business sector, as well as property at PT. Quality Property Indonesia. The company is engaged in property by selling its products in the form of houses, apartments and shop houses, which began in 2015 until now. In handling its sales information system this company can be said to still do it manually. The company is still using the conventional sales system in the form of marketing through word of mouth and using media brochures, so that the scope of marketing sales is still limited and can not be extended to various areas causing the products sold are less well known by the wider community. Another obstacle experienced by property sales service companies is the difficulty in buying and selling transactions, namely storing and searching for buyers and sellers' data that are piled up in the file cabinet, the difficulty of recording reports on property unit sales still using Microsoft Excel, and in making reports still using Microsoft Excel.
