Our Methodology
How we collect, verify, and present procurement opportunities from across Malawi and international development organizations.
Data Collection Pipeline
TendersMW uses automated scrapers to collect procurement notices from multiple official sources. Our pipeline runs multiple times daily to ensure timely coverage.
Government Portals
PPDA (ppda.mw) and MANEPS (maneps.mw) are scraped for all publicly posted procurement notices, including open tenders, restricted tenders, and procurement intentions.
International Development
World Bank, African Development Bank, EU TED, and UNGM procurement portals are queried for Malawi-specific opportunities using their public APIs and search interfaces.
Parastatal & Utility Tenders
Major Malawian entities like ESCOM, water boards, and city councils publish tenders on their own websites. We monitor these sources for new procurement notices.
Categorization System
Every tender is classified into one of 10 procurement categories based on the tender title, description, and procurement method:
| Category | Description |
|---|---|
| Goods & Supplies | Equipment, materials, furniture, vehicles, office supplies |
| Construction & Works | Building, road, bridge, renovation, infrastructure projects |
| Consulting Services | Consultancy, advisory, assessments, evaluations, studies |
| IT & Technology | Software, ICT, computers, networks, digital systems |
| General Services | Cleaning, security, catering, maintenance, repair |
| Health | Medical supplies, pharmaceuticals, hospital equipment, clinical services |
| Agriculture | Farming, irrigation, fertilizer, seeds, crop management |
| Education | Training, workshops, textbooks, learning materials, capacity building |
| Energy & Water | Solar, electricity, power, water supply, boreholes |
| Transport & Logistics | Vehicles, freight, shipping, logistics, distribution |
Quality Scoring
Each tender listing receives a quality score (1-5) based on data completeness:
Complete
Title, entity, reference, dates, description, documents, contact information all present.
Good
Most fields present. May be missing contact info or detailed description.
Adequate
Essential fields present (title, entity, closing date). Missing some details.
Minimal
Basic information only. Missing key fields like closing date or reference number.
Incomplete
Title only. Insufficient data for reliable use. Listed for completeness but may not be indexed.
Tenders with a quality score below 3 are marked as noindex to prevent search engines from displaying incomplete information.

| PPDA new tenders | Every 4 hours |
| MANEPS new tenders | Every 4 hours |
| International sources (World Bank, AfDB, EU TED) | Daily |
