Infrastructure and construction accounts for the largest share of international procurement spending, followed by healthcare, IT, energy, and water — together representing over $150 billion in annual tender volume from multilateral development banks and UN agencies alone. The World Bank committed $72.8 billion in fiscal year 2024, the ADB approved $24 billion in 2024, and the AfDB's recent $11 billion ADF replenishment ensures growing pipeline across Africa. Each of these institutions channels the majority of its lending through competitive procurement across six core sectors.
For contractors, suppliers, and consulting firms, choosing the right sector to target is the single most important strategic decision in international procurement. This article breaks down where the highest tender volumes and contract values are, what drives demand in each sector, and how to position your business based on your existing capabilities.
1. Infrastructure and Construction
Infrastructure and construction is, by a significant margin, the largest sector in international procurement. Road construction and rehabilitation, bridge building, airport and port development, public buildings, housing, and urban infrastructure projects account for a substantial share of all development bank lending.
The demand drivers are straightforward. Developing countries need physical infrastructure to support economic growth, and much of the existing infrastructure is aging or inadequate. The World Bank, AfDB, and ADB all allocate large portions of their lending portfolios to infrastructure. South Africa alone committed R1 trillion ($61 billion) to infrastructure in its 2026 budget.
Within infrastructure, the sub-categories with the highest tender volumes include:
- Roads and highways: Rural road rehabilitation, national highway construction, and urban road upgrades are the single most common tender type in many developing countries.
- Buildings and facilities: Schools, hospitals, government offices, warehouses, and community centers.
- Water infrastructure: Dams, reservoirs, water treatment plants, and distribution networks (often overlapping with the dedicated water and sanitation sector).
- Urban development: Drainage systems, solid waste management facilities, public spaces, and urban transport.
Infrastructure tenders tend to be high-value, which means they are also highly competitive. Winning requires demonstrated experience with similar projects, strong financial capacity, and often a local partner in the country where the project is located.
2. Healthcare and Pharmaceuticals
The healthcare and pharmaceutical sector has seen sustained growth in international procurement, with global health ODA exceeding $40 billion annually according to the OECD. The US alone maintained $9.5 billion in global health funding in its FY2026 budget (including PEPFAR at $4.4 billion), while multilateral health mechanisms like the Global Fund command billions more. Procurement in this sector spans a wide range of goods and services.
Medical supplies and equipment represent the most straightforward opportunity. Tenders for diagnostic equipment, laboratory supplies, hospital furniture, ambulances, cold chain equipment, and personal protective equipment are published regularly by both governments and international organizations.
Health system strengthening generates consulting and technical assistance tenders. Development banks and UN agencies fund projects to improve health information systems, train healthcare workers, develop national health strategies, and strengthen supply chain management for pharmaceuticals.
Pharmaceutical procurement is a specialized sub-sector dominated by large-volume tenders for essential medicines, vaccines, and diagnostics. Organizations like UNICEF, the Global Fund, and WHO are major procurers, and their tenders are typically open to pre-qualified manufacturers.
The healthcare sector rewards specialization. Companies that invest in understanding the regulatory requirements, quality standards, and distribution challenges specific to health procurement in developing countries tend to build strong, repeat-business relationships with procuring entities.
3. Information Technology and Telecommunications
Digital transformation is reshaping procurement in developing countries, and the IT and telecommunications sector is one of the fastest-growing areas of international procurement. The World Bank's $137 million WARDIP program for West African digital integration, the $200+ billion in AI investment commitments from the New Delhi Declaration, and ADB's digital transformation initiatives across Asia all reflect a sector growing at 15-20% annually in development bank portfolios. Governments across Africa, Asia, and Latin America are investing in technology to improve service delivery, increase transparency, and build digital economies.
Key sub-sectors generating tenders include:
- E-government platforms: Citizen service portals, digital identity systems, electronic procurement platforms, and tax administration systems.
- Management information systems: Financial management, human resources, health information, and education management systems for government ministries and agencies.
- Network infrastructure: Fiber optic backbone networks, last-mile connectivity, data centers, and cloud infrastructure.
- Cybersecurity: As digital systems expand, so does the need for security assessments, monitoring tools, and incident response capabilities.
IT tenders often have both a hardware/software component and a services component (implementation, training, maintenance). Companies that can deliver end-to-end solutions -- from system design through deployment and support -- are well-positioned in this sector.
The ADB (Asian Development Bank) has been particularly active in funding digital infrastructure and e-government projects across Asia, making it a key source to monitor for IT firms targeting that region.
4. Energy and Environment
The global push toward universal energy access and the transition to renewable energy are driving strong procurement demand in the energy and environment sector. This sector encompasses both large-scale power generation and transmission projects and smaller distributed energy solutions.
Renewable energy is the fastest-growing sub-sector. Solar PV installations, wind farms, mini-grids, and battery storage systems are being procured at increasing scale across Africa, South Asia, and Southeast Asia. The EU's Clean Energy Investment Strategy alone calls for EUR 660 billion per year in energy investment. These projects generate tenders for equipment supply, engineering and construction, project management, and environmental and social impact assessments.
Grid infrastructure remains a major procurement category. Transmission line construction, substation installation, distribution network upgrades, and smart metering systems are funded by development banks in countries working to expand and modernize their electricity networks.
Environmental consulting is a cross-cutting opportunity. Almost every major infrastructure, energy, or industrial project funded by a development bank requires an Environmental and Social Impact Assessment (ESIA). Firms with expertise in environmental assessment, climate risk analysis, biodiversity management, and social safeguards can find a steady stream of consulting tenders.
5. Water and Sanitation
The water and sanitation sector occupies a unique position in international procurement because it sits at the intersection of infrastructure, public health, and environmental sustainability. The Sustainable Development Goal for clean water and sanitation (SDG 6) has mobilized substantial funding, with the World Bank alone committing over $10 billion in active water sector projects globally. An estimated 2.2 billion people still lack access to safely managed drinking water (WHO/UNICEF 2023), driving sustained procurement demand from development banks and bilateral donors.
Tenders in this sector include water supply system construction (boreholes, wells, treatment plants, pipe networks), sanitation facility development (sewage treatment, latrines, septage management), irrigation infrastructure for agriculture, and flood management and drainage systems.
Water sector contracts range from small community-level installations to multi-million-dollar urban water supply programs. The sector is particularly active in Sub-Saharan Africa, South Asia, and Southeast Asia, where access gaps remain largest.
6. Consulting and Technical Assistance
Consulting is not a sector in the traditional sense, but it cuts across all the sectors listed above and represents a significant share of international procurement spending. Development banks fund thousands of consulting assignments annually for project preparation, feasibility studies, design and supervision, institutional reform, policy development, capacity building, and evaluation.
Consulting tenders are typically procured through shortlist-based methods, where firms first submit Expressions of Interest, are shortlisted based on qualifications, and then submit full technical and financial proposals. The quality of your team -- their CVs, relevant experience, and language skills -- is often more important than price in consulting procurement.
Firms that succeed in development consulting typically specialize in two or three sectors and build deep track records. Generalist firms struggle to compete against specialists with demonstrated experience in specific technical areas.
How to Specialize and Win
The most common mistake companies make when entering international procurement is trying to bid on everything. The firms that win consistently are those that specialize. Here is a practical framework for choosing where to focus:
Assess your existing capabilities. Which sectors align with your current products, services, and expertise? Entering a new sector from scratch is expensive and time-consuming.
Evaluate the competition. Some sectors and geographies are more crowded than others. Look for niches where your specific experience gives you a competitive advantage.
Follow the funding. Monitor which sectors are receiving the most investment from development banks. The World Bank, ADB, and AfDB all publish their lending pipelines, which signal where tenders will emerge in the coming months and years.
Build your track record incrementally. Start with smaller contracts to build references, then use those references to pursue larger opportunities.
Use sector-specific intelligence. On BidsFactory, you can browse tenders by sector -- infrastructure, healthcare, IT, energy, or water -- to see the current volume and types of opportunities available. This real-time intelligence helps you validate your sector strategy with actual data rather than assumptions.
The Bottom Line
International procurement offers genuine, large-scale opportunities across multiple sectors, but success requires focus. The companies that win are those that understand their target sectors deeply, monitor tender pipelines systematically, and invest in building the capabilities and relationships that procurement evaluators are looking for. Pick your sectors, know your funders, and start bidding strategically.
