How we procure

UNOPS procurement activities are based on the careful and responsible management of our funds or the funds entrusted to us by a partner.

Procurement principles

UNOPS procures according to the following principles:

  • Best value for money
  • Fairness, integrity and transparency
  • Effective competition
  • Best interest of UNOPS and its partners

We are committed to making sustainable procurement our default mode of procurement. UNOPS personnel involved in procurement activities consider sustainable procurement to the extent possible within the context of their work, the country, the industry sector and the supply market.

Becoming a UNOPS supplier

UNOPS is a member of the United Nations Global Marketplace (UNGM) — the common procurement portal of the UN system. All UNOPS suppliers must register with UNGM, where suppliers gain access to a global market of over $17 billion annually across UN organizations.

UNOPS expects all vendors who wish to do business with UNOPS to embrace the United Nations Supplier Code of Conduct, as well as to adhere to principles of the United Nations Global Compact.

The majority of UNOPS procurement processes are carried out through the UNOPS eSourcing system — an e-tendering platform integrated with UNGM. The platform manages the following procurement process stages: sourcing, solicitation, bid opening, evaluation and award.
