We understand that you might have to charge your customers for the return labels a lot of times and we have built a way to let you do so. Just follow the below steps:
1. Click on the refund button available on the request detail page.
You can choose the change the refund amount and charge the applicable fee to the user.
Pro-Tip: We do not recommend you charging customer a return fee on their first return with you. The first experience for them is about building trust and that builds a foundation for their further association with you.
