The business market has a large number of participants, the company and suppliers and their interaction will be analyzed in detail. Before buying, the company must form a team of people or a purchasing center that will recognize the problem, actually detect the lack of raw materials in production, define the specifications that the material must meet, consider suppliers and ultimately select the appropriate supplier who will meet all criteria. Organizational purchasing is influenced by several factors such as environmental factors, organizational factors, interpersonal factors, and individual factors. There are various situations in which a company may find itself when purchasing the necessary raw materials and supplies. And these are situations when a company makes a routine purchase, when a company corrects product specifications, and when it buys a particular product for the first time. It is very important for a company to build quality relationships with suppliers and to constantly develop those relationships in order to create long-term business cooperation.
