How to manage returns on shopify?

Shopify provides a baseline for returns (labels, restocking, refunds), but it lacks a branded self-serve portal, automated exchange flows, and real-time inventory visibility for exchanges. Purpose-built solutions like Swap integrate directly with Shopify to automate the entire post-purchase experience, customers can self-initiate returns without contacting support, and brands can set automated rules for refunds, store credit, or exchanges.
