Information systems in business are primarily based on monitoring the financial and accounting operations. In Republic of Croatia, business entities are obliged to based its financial performance on double-entry bookkeeping. The unified general chart of accounts which obliges entrepreneurs to use unified charts for the purpose of recording of accounting changes is defined by Accounting Act NN 78/15 and NN 134/15. The authors of this paper are going to show the current record of accounting changes and changes brought by the new law. Furthermore, the authors will demonstrate the ability to capture accounting changes through information and communication technologies and the possibilities for future implementation and collaboration, i.e. integration of information systems. The assumption is that a unified general chart of accounts will enable easier processing of reports and will contribute to simpler collaboration among businesses entities and reduce the need for consecutive data writing.
