Digitization is the use of digital technologies to transform a business. Of course, it’s not just about technology, but also about how it really changes the way they work (processes) and the ways those processes adapt to improve business. Digitization has entered the big door at high speed. The transformation it brings sets completely new business rules and irreversibly changes the ways of doing business and the industry. Advances in technology and the use of complex information systems have taken business to a whole new level. Getting rid of unnecessary physical documents and switching to a "paperless" form of business is not a luxury, but the foundation of efficient and successful business in today's business world. This does not only mean the digitalization of business to customers, but great emphasis is placed on digitalization from within. Without full research and adoption of the mobile workflow, companies will face challenges such as dissatisfied users, slow processes, lack of access to content, and reduced data protection capabilities. Investing in digitalization is a long-term profitable investment in the future. Companies that do not adapt and do not accept digitalization will increasingly struggle with administrative and financial difficulties and will eventually simply disappear from the market. Although changes are much more difficult to implement in small and medium-sized enterprises, they are very necessary. Changing something well-established and routine always provokes employee repulsion. Skepticism towards the new and digital, fear of not being able to master new technologies and lack of IT resources are obstacles that everyone faces. When it comes to business digitalization, it is important to note that this is not a one-time operation, but, similar to the implementation of ERP, a long-term business strategy and decision-making that should be based on the company's management to really prepare its business and its company for future challenges, by using different ways of processing data like Big Data or introducing new systems and ways of connecting - the Internet of Things. Websites, mobile applications and data storage on the Cloud are already an indispensable part of a successfully digitized company.
