Partial Fulfillment Process

I need to set up a partial fulfillment process for my Shopify store. Here are the details:

Store name: [YOUR STORE NAME]
Common reasons for partial fulfillment: [e.g., items from different warehouses, backorders, pre-order items mixed with in-stock items]
Number of fulfillment locations: [NUMBER]
Customer communication preference: [e.g., email for each shipment, single summary email]

Please help me create:


  A clear policy defining when partial fulfillment is appropriate versus holding the entire order until all items are available.
  Step-by-step instructions for partially fulfilling an order in Shopify admin, selecting only the items that are ready to ship.
  A customer notification email template for partial shipments that explains: which items are shipping now, which items are still pending, and the expected timeline for the remaining items.
  A tracking system for orders with pending fulfillment, including how to filter and view all partially fulfilled orders in Shopify admin.
  A workflow for handling the remaining items: automated reminders to check stock, re-fulfill when items become available, and close out the order.
  Guidelines for shipping cost handling: whether to charge shipping once or per shipment, and how to handle free shipping thresholds.
  A process for customer service to explain partial fulfillment to customers who contact support.
  Automation rules to tag partially fulfilled orders as “Partial-Fulfillment” and notify the warehouse team about pending items.
  A weekly report showing all orders stuck in partial fulfillment status for more than [NUMBER] days.
  Escalation procedures for items that remain unfulfilled after a defined period.
  Instructions for issuing partial refunds if remaining items cannot be fulfilled.
