Leadeks is a company selling laboratory equipment for packing quality control. The organization gives full-cycle recommendations, provides after-sales support, trains the staff, performs an adjustment, etc. During the research, we have found out that it is important for the client to find a seller who will give professional recommendations, will not leave after the purchase, will support and solve emerging problems. At the same time, selling companies are trying to escape responsibility and tend to forget about their customers after the sale, because it is a one-time purchase. It was necessary to show that Leadkes is not afraid of responsibility, it helps to find competent solutions both before and after the purchase.
