Submit Bid option is not available for some tenders on e-tendering portals

First, vendors need to register on e-tendering portals like www.ireps.gov.in or www.gem.gov.in to participate in tenders published on that   portal/website. Any registered vendor can participate in bidding before tender closing date/time for open tenders (advertise tenders) published on e-tendering portals.

For tenders other than open type (advertise tenders) only those registered vendors can participate in bidding which are addressed/included in tender by tender publishing authority. If vendors were addressed or included in tender then they should get mail/message after tender publishing.

So if vendors are not able to submit their bids for a tender then it means either they are not registered as a vendor on e-tendering portal or tender is of other than open type (advertise tenders) and they are not addressed for that tender.
