Implementation of the Goods and Services Tax (GST) has had a positive impact on the logistics of businesses, while glitches in the GSTN portal, cumbersome procedures and cost of compliance remain major areas of concern, industry body Ficci said on Sunday, citing its survey in this regard. The Federation of Indian Chambers of Commerce and Industry (Ficci) had conducted a survey on the experiences of micro, small and medium enterprises (MSMEs), as well as large corporates, on the first six months of the GST which was rolled out from July 1. "More than 60 per cent of respondents stated that their experience with respect to inter-state transportation of goods has been good in terms of check-posts," a Ficci release said here.
