It’s been four weeks since the Centre decided to demonetise high-value currency notes but the consumers’ cash crunch has had a mixed impact on online businesses. According to a report by Redseers, a consulting firm, e-commerce has suffered heavily post demonetisation since most people still prefer cash on delivery of products.Despite this setback, the future looks rosy for e-commerce in India.

The Bill covers transactions through all modes, including offline, online, through electronic means, teleshopping, or other multi-level marketing and also recommends adequate penalty for erring manufacturers and traders. By introducing demonetisation, the government has pushed more and more people to move online; it now must keep its part of the deal by passing the law and securing the interests of the consumers.
