This thesis discusses the satisfaction of customers with NASHE COSMETICS products. Namely, customer satisfaction, its further transmission of experiences that are positive and their retention is the result of a positive difference that occurs between expectations and perception. On the other hand, customer dissatisfaction can arise when it happens that their expectations are higher than their perception. Open positive or negative feelings are a display of customer satisfaction or dissatisfaction with the service provided or with the purchased product, and such a feeling occurs after the purchase. The role of customer satisfaction is important in building a positive and quality reputation of a company because it must always insist on keeping the satisfaction of its potential or regular customers at the level or even go above it and thus exceed expectations. If there is a loss of one customer, it always carries with it the risk that a chain of losses will occur. Every company should and should incorporate the satisfaction of its customers and their loyalty into its long-term business development strategy. Measuring and monitoring customer satisfaction is of great importance for the company's business because repurchase is one of the indicators of satisfaction and loyalty that reduces the loss of customers and ultimately reduces negative reviews of the product or service. NASHE COSMETICS is a company engaged in the production of handmade cosmetic products that stand out on the market primarily with their distinct quality, but also the original visual identity of the product. The products they make and sell contain only the highest quality ingredients from nature that are handmade. In order to be able to examine and investigate the satisfaction with NASHE COSMETICS products, the method of data collection via the Online Questionnaire was used. The aim is to examine as many consumers and customers of different ages as possible in order to get a more complete picture of customer satisfaction with Nashe Cosmetics products.
