Within module 3, five success stories from the domain of electronic commerce were presented. These are companies that have been successfully operating in retail for many years, and who, through the process of digitalization of society, saw that electronic commerce is a necessary aspect of any business. In 4 written interviews and one video interview, you will have the opportunity to hear stories from the following companies: Donator, Okov, Mercator Crna Gora, Voli trade and Nall International, which talked about their beginnings, milestones, ideas, success and advice for future e-traders. We have chosen companies that are synonymous with successful business on the Montenegrin market.
