Gst on advance payment

if invoice raised before 01.07.2017 charging VAT then credit of VAT will be transfered by following transition provision given u/s 139 to 142. 

I need information for GST liability on advance payment. post 01st july 2017

GST is payable on payment or issue of invoice whichever is earlier. So advance payment under will liable to pay GST. 

Who will raise invoice for advance payer or payee. Pls provide details or relevant links if avaliable

Thank You

On receipt of advance from the customer, the supplier of goods will issue a receipt voucher evidencing the receipt of advance and details will be entered in GSTR-1

Exactly, the customer can claim ITC later on.
