Electronic procurement has become one of the main e-government initiatives for many countries as they look to improve procurement through a more open, competitive, and transparent environment. E-procurement continues to prove itself as a viable alternative to manual processes, bringing cost savings and efficiencies. The Asian Development Bank has been a promoter of electronic government procurement (e-GP) as a key component for procurement reforms through active involvement in the Multilateral Development Bank Working Group on e-GP. This handbook aims to inform readers about e-GP, provide a reference for related concepts, and examine how e-GP implementations have taken shape in different jurisdictions worldwide.
