Build an RMA Workflow for Returns

Help me design and implement a Return Merchandise Authorization (RMA) workflow for my Shopify store [STORE NAME]. I need a structured process that includes:


  A method for customers to request an RMA through [PREFERRED CHANNEL: email, form, portal].
  Automatic assignment of a unique RMA number to each approved return request.
  Criteria for approving or denying RMA requests based on [RETURN POLICY RULES].
  Internal notification to the fulfillment team at [TEAM EMAIL] when an RMA is approved.
  Customer notification with RMA number, return instructions, and shipping label if applicable.
  Tracking of RMA status through stages: Requested, Approved, Shipped Back, Received, Inspected, Resolved.
  Integration with Shopify order data so RMA records link directly to the original order.
  A tagging system in Shopify to mark orders with active RMAs using tags like [RMA TAG PREFIX]-[NUMBER].
  Escalation rules for RMAs that remain unresolved after [NUMBER OF DAYS] days.
  Reporting on RMA volume, approval rates, and average resolution time.
  Suggest Shopify apps or Flow automations that can support this workflow.
  Provide a checklist my team can follow when processing each RMA step.
