Due to the changes caused by the corona virus pandemic, the introduction of electronic public administration services (e-Administration) has been accelerated. Namely, certain digital processes of electronic services came to life precisely because of the necessity of the existence of the system and its users. The paper analyzes the achieved project activities of digitalization of public administration and the introduction of electronic business (e-Business) into business processes. Some forms of e-Business are listed. The justification for processing electronic invoices (e-Invoice), receiving letters electronically (e-Office), conducting public procurement procedures by receiving bids electronically (e-Procurement) and calculating employee salaries through Centralized Payroll (CP) is shown. By introducing information systems into business processes, it is possible to improve the quality of the processes themselves and business in general. Business processes are automated, which enables faster performance of business tasks with less possibility of error. Additional advantages of such a way of doing business are an increase in work efficiency, a reduction in operating costs, more options for data analysis, and safer data storage. Electronic way of doing business means doing business without paper. Such a way of doing business makes it possible to process and retrieve documents and view them from one place. It is not necessary to physically be at a specific address. With the introduction of electronic invoices in business, invoices are no longer sent by mail. This reduces paper and postage costs, and increases the speed of delivery of invoices sent through the IT system.
