I want to ask a question and please everyone provide your suggestions. My father is a small businessman dealing in power tools. This is basically and unorganized sector. He isn't registered as a dealer and thus books of accounts is not maintained by him. I want to ask with the incoming gst how the power tools sectors will be affected and should my father go for registration so that he can avail the set off benefits. But for such small businessman account maintenance and invoicing is a problem. Will gst affect my fathers small business.?
