We are an India based web hosting company using PayPal to accept payments from customers outside India.
As we don't charge GST to customers outside India, all the revenue we receive from PayPal is treated as an export business. The settlement we receive from PayPal is in INR.
We have few refunds pending from GST office. In order to get that refund, we need a letter from PayPal stating that "PayPal has received the payment in USD behalf of our company and settled in INR to our account.
