E-procurement is one of the most important sophisticated technologies employed by both the public and private sectors throughout the world. Many top-tier firms use this electronic platform in the procurement process to accomplish operations more efficiently and effectively by reducing corruption and other unusual expenses. At this moment Sri Lanka is facing for a severe financial crisis. The major causes of these problems include a reduction in Sri Lanka's dollar reserves, currency depreciation, and the impact of the covid-19 epidemic. Currently, the government spends a lot of money on the procurement process in the public sector. To recover from this situation, government may adopt an e-government procurement system into the public procurement process, which will help to save the billion rupees to the country by decreasing corruption and unnecessary expenses. Based on the past articles, we have identified there are several studies which have been conducted on E-government Procurement systems around the world. Procurement plays a vital role in a country as it is one of the major tools to build up a strong economy and gives value for money. With the development of technology, procurement has been adopted to an electronic platform that enables more effective and efficient processes for the government. By observing previous studies, researchers have determined some significant factors influencing the implementation of electronic government procurement. This paper has been conducted a systematic literature review based on findings of previous articles related to this study area.
