Dear Querist,
Yes. If you were the seller and the clothing was supplied to customers outside your State, GST registration was mandatory despite turnover being only ₹4.4 lakh. Inter-State taxable supplies of goods generally require registration irrespective of turnover.
To regularise, have the Shopify and Qikink records reviewed.
For a more detailed review of your case, you may book a phone consultation.
