Despite the potentials promised by the vendors of such systems, eProcurement got off to a slow start. A study by (Eyholzer and Hunziker, 2000) shows that only 18 percent of the Swiss companies analyzed used electronic product catalogs, auctions or requests for quotations in procurement in the year 2000. According to this study, however, many companies were planning to implement eProcurement systems at that time. Other studies show similar proportions for other countries (e.g. Industrial Distribution, 2001 and Administration, 2000 for the USA). A study by (Wyld, 2004) reports that currently almost half of all American companies use eProcurement systems.
