Frequently asked questions

Which document should I rely on?

Always use the publishing organisation's current invitation and official amendments. This glossary explains terms; it does not change tender conditions.

Source and independence

Tender notices are published by National Treasury through the eTenders portal and by the individual buying institutions, which remain the authoritative sources. Tender Express is an independent search platform. It is not an official government service and is not affiliated with National Treasury. Always confirm details and download documents from the original source.
