Hi, @vssc
No problem, I’m more than happy to help!
Transaction fees would be charged for orders processed through the Razorpay gateway as well.
If you don’t use Shopify Payments or a manual payment method, then transaction fees apply for orders in addition to the processing fee charged by your payment provider. Also, transaction fees don’t apply for manual payment methods, which include cash on delivery (COD), bank deposits, checks, test orders, and draft orders marked as paid or pending. Transaction fees don’t apply for POS orders.
In regards to returns, the customer does not need to place a new order. You can follow the steps outlined here to edit an order. Hope this helps!
