E-Tendering
Running a procurement through an online portal rather than on paper.
E-tendering portals are the online systems public buyers use to publish tender documents, manage clarification questions, and receive supplier submissions electronically. Common examples include Delta, Atamis, In-tend and Proactis, and registering correctly on the relevant portal is usually the first practical step in bidding for a specific contract.
What e-tendering portals actually do
Portals typically host the full ITT documentation, provide a structured area for submitting clarification questions and viewing published answers, and include an online form or upload area for the tender return itself, often with a hard system lock at the submission deadline.
Because different buyers use different portal software, suppliers active across multiple buyers usually end up managing several separate logins and interfaces rather than one unified system.
Practical pitfalls to avoid
Portal-related failures are a common and entirely avoidable cause of disqualification: files uploaded to the wrong section, submissions completed minutes after a system deadline lock, or documents in an unsupported file format.
Testing document uploads well before the submission deadline, keeping file sizes within any stated limits, and building in time for portal registration or password resets removes most of this risk.
- Register on the portal as soon as you identify a relevant opportunity
- Check file format and size limits before the deadline
- Submit well ahead of time, not in the final hour
- Keep a screenshot or confirmation receipt of successful submission
- Monitor the portal for published clarification answers
Clarifications and communications through the portal
Most portals require all clarification questions and buyer communications to go through the system itself rather than by email, both to maintain an audit trail and to ensure all bidders can see published answers on an equal footing.
Frequently asked questions
- What happens if an e-tendering portal fails just before the deadline?
- Buyers generally expect suppliers to submit well before the deadline precisely to allow for technical issues, and most portal terms make clear that a system failure on the bidder's side is not automatically grounds for an extension, though genuine platform-wide outages are usually treated more sympathetically.
- Do I need a separate account for every buyer's e-tendering portal?
- Usually yes, since different buyers often use different portal software such as Delta, Atamis or In-tend, each requiring its own registration, though some portal providers let you reuse the same login across multiple buyer instances of their system.
- Can I submit clarification questions by email instead of through the portal?
- Most buyers require clarification questions to be submitted through the e-tendering portal itself, not by email, to keep a clear audit trail and ensure fairness. Check the instructions to tenderers for the buyer's specific process.
