I m book keeper from India but not able to pay subscription charges for my Australian client from my Indian card. Pls help

Paying an Australian QuickBooks Online (QBO) subscription directly via an Indian bank account isn't supported because Intuit requires a supported credit/debit card (Visa, Mastercard), a regional direct debit tied to the subscription's billing market, or payment via PayPal.

This means we're unable to link a foreign or Indian local bank account directly into the QBO billing portal for automatic debits.

In this case, you need to use an Australian-issued credit card or PayPal that permits international transactions and foreign exchange conversion.

I'm adding this page for more information: Manage billing, payment, and subscription in QuickBooks Online.

Let me know if you have any other concerns.
