"E-tail is the most recent segment, but its highest growth rates and success will be the key driver of the overall e-Commerce market," said a UBS report.
The Internet & Mobile Association of India (IAMAI) estimates that the overall Indian e-Commerce market, of which e-tail is a segment, is currently worth USD 16 billion.
The report made a specific mention of the Indian Railway Catering and Tourism Corporation (IRCTC) as "the best example" of a successful Indian e-Commerce venture.
The marketplace model of e-tailing will gain prominence "as it is scalable and requires less capital and time than other models".

"Current regulations and the presence of large unorganised sellers (mom-and-pop shops) also support this model," it added.
Multi-product e-tailers (Flipkart, Amazon India and Snapdeal) are moving towards the marketplace model while e-tailers in niche categories such as furniture, baby products and grocery have hybrid business template, the report pointed out.
"Analysis of the supply chain for offline retail by category implies adequate margins for e-tail in future," the report stressed.
