- Before the close of bidding time if any changes are required in the NIT, Tender Manager can add Corrigendum for the NIT.
- After bid closing, two committee members (one from Marketing Department and other from Finance Department) must be logged in.
- After the two committee members successfully logged in, Tender Manager can decrypt the price given by the bidder through the DSC.
- After the price decryption. Tender Manager can AWARD or SEND FOR IMPROVISATION or DO NOT AWARD the particular NIT.
- For AWARD NIT: – Select the bidder from the list who will be awarded. After awarding the tender, the Tender Manager fills up the tender closing form and closes the NIT.
- For SEND FOR IMPROVISATION (Before BID Validity Time) – Select the bidder from the list to send improvisation. Again the NIT will republish for bidding for the selected bidder.
- For DO NOT AWARD – NIT will be closed.

The application provides interface to Nalco side (internal) users like tender manager, bid opener etc. and external users i.e. bidders. Being an on-line bidding application, Digital Signature Certificate (DSC) requirement is inbuilt into the system. DSC only from Indian Certifying Authority (CA) is acceptable.
