Online shopping is growing at a rapid pace, and we have witnessed this in particular in the last two years, followed by the great Pavida – 19 pandemic, which has actually accelerated this way of shopping even more. We are witnessing a great globalization of companies that are imposing themselves in competition, finding all possible ways to be more competitive in the market and at the same time gain a large number of customers who would also intend to become regular users of their products and services. Lean methodology in this paper has the only goal and that is how to get closer to the customer, while maintaining profits and not creating additional costs for their business. We will show this with this paper in both theoretical and practical part, and with the help of Lean tools we will try to improve and speed up all processes related to warehousing and thus increase the value of the company itself. As eKupi has been operating equally successfully for many years in our and foreign markets, we will prove with a fact-based questionnaire, which is how satisfied customers are really satisfied primarily with the delivery service and the way of doing business that deserves all praise. And we are witnessing this with numerous recognitions and awards that have taken a high position in the market in recent years.
