GeBIZ, short for Government Electronic Business, is the Singapore government's one portal for public procurement: agencies post invitations to quote and invitations to tender, suppliers submit offers electronically, and the award is announced on the same notice. The agencies which publish on GeBIZ range from ministries and statutory boards to schools and polytechnics, so Ministry of Education school quotations for coaches, buses and manpower sit beside multi-year tenders from bodies such as the National Environment Agency.
Searching is open; bidding is not. Suppliers register as GeBIZ Trading Partners, local firms under their UEN and foreign firms without one, and tender documents and bids sit behind their log-in, while the notice, its items, corrigenda and award stay public.
The listing searches in title, document number, agency or procurement category, with match all or match any, and sorts by published date, closing date or relevance. A published-date filter narrows to today, the past two days or the past seven, and Today's Opportunities has its own link. The portal also carries a Listing of Indicative Government Procurement Opportunities for planned buys.
