How to sell goods in GST by drop shipping where I tell my supplier to directly supply goods to my customer.
i don't want the customer to get the invoice from the supplier as it will disclose my purchasing price and contact details of the supplier.
I read that that delivery challan can be used. but how to use it.
i mean who should issue delivery challan?
me or the supplier?
please help me on this.
