This system manages the various stages of the bidding process online, including the identification of supplier sources, the invitation to bid (publication of bidding documents), the opening of bids, the evaluation process and the awarding of contracts.

Procurement with Sustainability and Gender Approach

UNOPS promotes the gender and diversities perspective as a key element in biddings; favoring opportunities for businesses led by women and young people, the inclusion of people with disabilities and people in vulnerable situations, throughout their procurement processes.

Driven by UNOPS commitment to sustainability and risk management in procurement, it implements the DRiVE programme (Delivering Responsibility in Vendor Engagement). The overall scope of DRiVE is to ensure that UNOPS vendors operate responsibly and in accordance with high standards of integrity through the development of a vendor assessment, inspection and corrective action-planning programme, with a particular focus on the associated areas related to human rights, labour rights, ethical conduct, sexual exploitation and abuse and environmental responsibility.
