eSourcing platforms

Where you actually build and submit the bid. Each one needs its own supplier account.

This is where the bid actually goes, and it is where the sprawl lives. Buyers choose their own platform, so responding to two contracts can mean two separate supplier accounts, two password policies and two document upload formats. Around 63 named platforms operate roughly 653 buyer-facing sites between them: In-tend alone accounts for about 358, because every buyer gets its own subdomain and its own registration. You cannot pre-register on all of them and there is no point trying. Register when you find work worth bidding for, and leave enough time before the deadline to get through the account approval.
