Return/Exchange Size Availability Option
It would be very helpful if customers could select their preferred size during the exchange process, with real-time visibility of stock availability on the website.
For example, when a customer initiates an exchange, the system should show whether the requested size is currently in stock. If the size is unavailable, it should display “Sold Out” instead of allowing the exchange to proceed.
This feature would prevent unnecessary back-and-forth communication, improve customer experience, and reduce manual handling for merchants. Platforms like Revolve already offer this type of functionality, and it would be an excellent addition to AfterShip Returns.

Dear customer,
Thank you for letting us know your request. We haven't displayed the inventory quantity in the returns page, but if you disable "Continue selling when item is out of stock" in Shopify. The item will be excluded from the available exchange as well.
Hope this could solve your request, looking forward to seeing your reply.
What are your thoughts on this idea?
