Dvat

mere website is not an issue for vat or  any  other  department 

volume and nature of  goods  purchase /  sale / manufacture is  the criteria  for  Excise /  Vat and service  tax.  

Thanks a lot, 

But if any product shown as display on website for order booking than intimation will be required?

display of an  item on website, does not confirms that the website owner is legimate  manufacturer or seller of the goods, it may be tie  up  with some  some  vendor  to sell the goods through their  portal on profit  sharing or  commission basis. 

invoicing of the goods matters,  where the  vendor has to come under the cover of laws of their state. 

In case we also accept advance payment (fully/partially) for such booking than same will be required?
