Changes in the way of communication between employees in the company and all participants outside it affected the business of the company. Information communication technology means all technology, collecting, processing and storage of information as well as the transmission and use of all types of information. Further development of technology led to the phenomenon of Web 2.0, which marks a new era of two-way communication. It is based on the idea of enabling users to participate in the creation of web page content and implies interactive two-way communication between users and computers and between users and other users. More and more communication is being transferred to online channels and business is moving to the cloud, so there is an increasing use of different collaboration tools. Collaboration tools are one of many different tools of Web 2.0 technology. They help company to implement projects, they improve communication with users, facilitate work in teams, enable free calls, create private social networks and so much more. Many companies also accept the concept of virtual organization in order to meet the increasingly frequent requests of their employees, especially younger ones, to work from home, as this allows them more flexibility in scheduling work tasks and better balancing work and free time. Some of the tools that companies are increasingly using are Trello, Yammer, Slack and 3CX. Analyzing the advantages and disadvantages of each tool, a conclusion can be made as to which tool to choose to improve the company's operations. The decision primarily depends on the size of the company, the type of work they do, the needs of the company, and the company's ability to implement the tools in its business. Whichever tool they choose, companies can have multiple benefits and using the tool in their daily work helps them stay up to date with the latest developments in modern technologies.
