International development tenders explained
What development tenders are, who funds them, the notice types (RFP, ITB, EOI, RFQ) and how the procurement process works — a plain-English guide.
“International development tenders” are the formal procurement notices that development funders publish when they need to buy goods, works or services — from building roads and supplying vaccines to designing programmes and hiring consultants. Responding to them is how many firms, NGOs and independent experts win work in the development sector, which procures tens of billions of dollars every year.
Who funds development tenders
Most opportunities originate with a handful of large funders: the World Bank, the UN agencies via UNGM, and the regional development banks — the ADB, AfDB, IDB, EBRD and AIIB — along with the European Union and bilateral donors such as GIZ, AFD and the U.S. State Department. Each publishes on its own portal, which is why aggregators exist.
Tenders, grants and calls for proposals
Not every opportunity is a classic tender. Funders also issue grants and calls for proposals, usually aimed at NGOs, research institutions and civil society, where the funder supports an organisation's own initiative rather than buying a defined service. Tenders, by contrast, procure specified goods, works or services through competitive bidding. Both appear in development funding pipelines, and many organisations pursue a mix.
The main notice types
A Request for Quotation (RFQ) is used for lower‑value, clearly specified goods or services, awarded mainly on price. An Invitation to Bid (ITB) is used when requirements are precise and award is based on price and compliance. A Request for Proposal (RFP) is used for more complex needs where quality and methodology are evaluated alongside price. An Expression of Interest (EOI), sometimes called a prequalification, lets a funder shortlist potential suppliers before issuing a full solicitation.
How the process works
Each notice lists the issuing organisation, the country or duty station, a deadline and a reference number. Suppliers register on the relevant portal, download the bidding documents, and submit a compliant offer before the deadline. Higher‑value contracts often involve prequalification or shortlisting, and many are won by partnerships and consortia rather than a single firm. Evaluation weighs compliance, technical quality and price — and, increasingly, ethical and sustainability standards.
Where to find development tenders
Because opportunities are scattered across dozens of portals, monitoring them one by one is slow and error‑prone. MangoFetch brings them into a single, searchable feed — browse the live tenders, filter by funder or country, review contract awards, and see trends on the Intelligence dashboard.

Frequently asked questions
What is an international development tender?
It is a formal procurement notice published by a development funder — such as the World Bank, a UN agency or a regional development bank — inviting suppliers to bid to provide goods, works or services for a development project.
What is the difference between an RFP, ITB, EOI and RFQ?
An RFQ is for lower-value, clearly specified purchases awarded mainly on price; an ITB is for precise requirements judged on price and compliance; an RFP is for complex needs where quality and methodology are weighed alongside price; and an EOI (or prequalification) shortlists suppliers before a full solicitation is issued.
Who can bid on development tenders?
Companies of all sizes, NGOs, research institutions and independent consultants can bid, depending on the notice. Most funders require a one-time supplier registration, and some higher-value tenders require additional prequalification.
