According to Divakar Vijayasarathy, the founder and managing partner of consulting firm DVS Advisors LLP, said GST on input is higher than GST on output in some manufactured goods such as footwear, man-made yarn and LED lights. “The most critical impact is on the working capital of the businesses since GST paid at higher rates on inputs is blocked till the grant of refund,” he said. The refund process is cumbersome and tends to be vulnerable to litigations, he added.
