How to bid on international tenders: a guide for global suppliers

Selling to buyers in another country follows the same logic as a domestic bid — read the rules, comply exactly, price competitively — but adds a few cross-border wrinkles: eligibility rules, currencies, bid guarantees and language. This guide covers what changes when you go global.

1. Know where global tenders come from

Broadly, international opportunities fall into three families, each with its own rules:

• Government procurement — each country runs its own public e-procurement notices, and increasingly publishes them as open data (see our open-contracting guide).
• Multilateral development banks (MDBs) — the World Bank, ADB, EIB, IsDB and others finance projects where the borrower government is the buyer but the bank sets the procurement rules.
• UN agencies and NGOs — the UN buys through the UN Global Marketplace (UNGM); large NGOs and foundations run their own RFP/EOI processes.

2. Register and get “vendor-ready”

Most systems make you register once before you can bid. Have a clean vendor pack ready: incorporation and tax documents, audited financials, reference contracts, and standard certifications. Common registrations include UNGM (for the UN), MDB consultant rosters/DGMarket profiles, and identifiers such as a UEI (US) or an EU economic-operator profile. Keep everything in English or with certified translations.

3. Read the notice type correctly

International notices use a familiar vocabulary — ITB / RFB (bids for goods and works), RFP (proposals for services), EOI (a shortlisting step) and RFQ (small, quick purchases). Know which one you’re answering: an EOI is not the place to send your full price, and an ITB usually leaves no room to negotiate scope.

4. The two-envelope system

Most large tenders separate your technical and financial offers into two sealed envelopes (or two encrypted uploads). Technical bids are opened and scored first; prices are opened only for those who pass the technical threshold. Never let a price slip into your technical envelope — it’s an instant disqualification.

5. Bid security, currencies and Incoterms

• Bid security / bid bond — often a bank guarantee for 1–3% of the bid value, valid past the bid-validity period. Arrange it early with your bank.
• Currency — bid in the currency the document specifies; watch the exchange-rate risk between submission and contract.
• Incoterms — for goods, price to the exact delivery term (e.g. CIP/DDP) named in the tender, or your comparison price will be wrong.

6. Consortia and local partners

Many international tenders reward — or require — local presence. A joint venture or consortium with an in-country partner can supply local knowledge, meet nationality rules and share risk. Agree the lead partner, liability and work split in a signed JV agreement before you submit; buyers ask for it.

7. Integrity and eligibility

Cross-border buyers screen for sanctions and past misconduct. Firms on the World Bank / MDB debarment lists or under sanctions are ineligible. Declare conflicts of interest honestly — integrity breaches are the fastest way to lose not just a bid but future access.

Golden rule: build a compliance checklist straight from the tender’s instructions-to-bidders and tick every item before you submit. Most international bids are lost on compliance, not price.
