With the implementation of RA 9184, all National Government Agencies (NGAs), Government Owned and Controlled Corporations (GOCCs), Government Financial Institutions (GFIs), State Universities and Colleges (SUCS) including Local Government Units (LGUs) are mandated to use the PhilGEPS. Suppliers, manufacturers, contractors, consultants are also required to register as well. Through the use of the PhilGEPS, transparency in government procurement is enhanced since opportunities to trade with government and the ensuing transactions are provided online. Information on changes in terms of references, bid schedules and on the winning bidder and contract amount are all accessible through the system. In addition, the electronic catalogue, which provides information on pre-approved cost of commonly used items, will help government auditors check that supplies purchased by a government agency are not grossly over-priced.
