Hey Sunny,

Sorry for the delayed response due to weekend.

Currently Payplans don't support multi-currency. As of now no plan to add in PP4.

There is a trick through which you can add different currencies to different
plans. But it totally depends on user, which plan he selects. This trick is useful if you do not have large number of variation in currencies.

Steps are as follows :
#1 : Create Group accordingly which has different currency. Like one Group for USD, another for INR and so on.
#2 : Set currency in Payplans->confirguration->Currency
#3 : Create plans which you want in the selected currency, set the appropriate Group and save the plans.
#4 : Repeat step 2 and 3 until all plans are created.

Note : The only issue is that,you need to take care of saving plans after changing currency in payplans configuration. Once you change the currency and save the previous plans again then those plans will also be changed to the current currency.

Let me know if you have any query.
