This profile is built from what portals disclose publicly. Since several states never release bidder lists or quoted prices, it likely understates the company’s true footprint. A tender is counted as won when the company either received the award or stood L1 at financial bid opening, even if the formal award is still pending. TenderKart compiles these public records independently and has no association with any government portal, buyer, or bidder.
