QB Online India subscription shows monthly INR 1059, and discounted price INR 137, but when we are making payment INR 1059 is getting deducted?????

I can help you explain the discounted price in QuickBooks Online, Girish Accounts.

The discounted price is INR 529.50/month, not INR 137 for three (3) months. 

If you've availed of the first trial, you'll have to pay INR 1059/month when you subscribe. You can check here.

I've included this article to check about understanding your subscription rates and charges in QBO.

I can always lend a hand if you have any other questions about your account.
