How to bid on SAP Ariba
Portal facts checked against the live portal in September 2026 · the notice always names the exact portal instance to use

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- What counts as SAP Ariba. A notice whose submission link points to this portal, including buyer-specific instances (18 addresses so far). Award notices rarely publish that link, so the awards side is undercounted. Notices from 18 Feb 2021 to 23 Oct 2026.
- Portal facts. Registration and login notes were checked on the live portal in September 2026. Portals change their sign-up steps; the notice’s own instructions take precedence.
- Independent. Portal and operator names belong to their owners and appear only to show where notices are published; Tenderline is not affiliated with, endorsed by or connected to any portal.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
