supply is not identifiable at the time of issue of voucher, e.g. voucher worth Rs. 1500 of Shopper Stop(a departmental store) issued on 1-1-2019 validity of voucher is 31-3-2019.

if in the above case a person do not redeem the voucher on of before 31-3-2019,
then there is no time of supply with respect to that voucher.

now , How shoppers stop will treat the amount of 1500 for which it does not have made any supply and received the amount .

if it considers it as supply then what will be the effect on Stock records.
