Disadvantages of e-procurement can be generally put in order as follows (Rankin et al., 2006: 83); • In this system, data are obtained from internal catalogues that are often updated. Provided that there is no effective follow up system, disadvantageous cases can be led to. • Data taking place in e-procurement systems include prices of materials, and these prices and even discounts should be regularly updated. In case that system is not continuously updated, problems for business can arise. • Prices, discounts, wages, and values continue to vary, and all of these should be often controlled. Due to lack of control, problems can occur in the system. • That main service providers are not operating for a time or, due to interruptions in internet, system is not supported, and work stops. • Long repayment times may form a disadvantage. • Due to technological troubles, technical problems can occur. • In unexpected cases such as costs, time, and etc., some confusion can occur in business. • Due to communication difficulty between potential purchasers and suppliers, impediments can be met.
