I know that GSTIN, EIC, RCMC, FIEO are required for proprietor doing export but apart from this do I require following ?
1) Shops and Establishment Act License [I don't know if it still exists and if I require it or not ?]
2) Registration for sales tax license [I am not sure if it still exists after GST introduce in 2017]
3) Udyam Registration (former name – “Udyog Aadhaar or MSME”) [I think this is optional and useful if want to avail government benefits on conducting business.]
