Government e-procurement portals use a DSC to authenticate the authorized user and digitally sign bid documents or submission actions. The exact workflow is controlled by the portal and tender.
1. Read the portal and tender instructions first
The Central Public Procurement Portal states that bidders generally require a Class 3 DSC with signing usage. Do not assume every portal or tender has identical requirements—confirm the current bidder instructions before purchase.
2. Match the authorized signatory
The DSC belongs to an individual. When bidding for an organization, the subscriber should be the director or authorized signatory acting for that entity, supported by the authorization required by the tender.
3. Prepare the token and computer
Install the supported token driver and any portal signer component from an official source. Keep the token PIN private, confirm the certificate is visible and avoid repeated incorrect PIN attempts.
4. Register or map the DSC
Many e-procurement systems require the certificate to be mapped to the bidder profile after enrollment. A renewed certificate may need to be registered again because it is technically a new certificate.
5. Test before bid day
Do not wait for the final hours. Check login, signer access, document format, file size, internet connection and the portal server time. Corrigenda can change requirements or dates, so review the official listing again before submission.
