The thesis is focused on the concept of sourcing and procurement market research. The thesis is divided into three terms, namely sourcing, market research and procurement. At the beginning of the paper, the concept of sourcing was discussed with its division into insourcing and outsourcing. The goal of the sourcing topic is to relate its importance to successful procurement. After sourcing comes the topic of market research and the steps in the process of market research. At the end, the topic of procurement and the procurement life cycle was covered. Without successful procurement, the company would not be able to operate efficiently. Successful procurement is made up of many factors such as price, delivery time, quality, supplier's inventory status, supplier's location and the like. Each company is individual and therefore has an individual approach to the procurement process. The aim of this paper is to provide insight and summarize knowledge about sourcing and procurement market research. In this work, research was conducted using the interview method. In the empirical part of this paper, the similarities and differences in the procurement process and the need to find new suppliers are highlighted. The purpose of this research is to gain insight into the approach to procurement and sourcing through three companies of different activities, namely retail trade, production of bakery and confectionery products, and distribution and sale of auto parts and equipment. At the end of the final paper, a comparative analysis was performed.
