E-way bill system will be in place on trial basis from January 16, 2018 and will be made mandatory from February 01, 2018 for Inter-state movement of goods. The states have an option to choose their timings for the implementation of E-way bill system for intra state movement of goods.
As we are nearing to July 1, 2017 GST will be a reality soon. For the transition from existing law to the GST law the government has made the transitional arrangements to carry forward the input tax credit under the existing laws to the GST law.
With the introduction of GST there will be easy credit flow mechanism, input tax benefits and reduced tax rates on supply of some goods or services. This is what the prima facie picture looks like but the intent of the government is to pass on the benefit of the same to the ultimate consumer. So if you are benefited by GST you have to pass on the benefit by reduction in prices.
