The document discusses different buying modes on the Government e-Marketplace (GeM) platform in India. There are three primary buying modes - Direct Purchase, Direct Purchase with L1, and e-bid/RA. Direct Purchase allows buying of low value items directly from sellers. Direct Purchase with L1 allows mid-value buys and requires comparing at least three sellers/OEMs to select the L1 or lowest price option. Transactions above Rs. 500,000 require an e-bid/reverse auction. The platform aims to promote policies like Make in India, purchasing from micro and small enterprises, and digitalization of government procurement.
