Yes, we can accept international payments into our Stripe and Razorpay accounts.
We recommend our Stripe account in the US to receive international payments as Razorpay in India does have some failures with international payments.
Note: we can accept payments in several other currencies into our US Stripe account, but it is not recommended unless there is a high enough transaction volume.
For example, if, on the org's behalf, we accept Australian dollars in Australia, they need to sell a hundred tickets or more in AUD to cover the currency conversion and processing fees from AUD to USD (to INR, if multiple conversions are required), that they will incur.
However, ticket buyers in Australia and other countries can pay in USD without any hassles and each buyer incurs the appropriate currency conversion charge.
