Your 2 systems use different order ID’s.
Retail Express order numbers start with the Year and a sequential number. Like 24-000000001
Shopify uses your own sequence like #1001
When an order goes to Retail Express it gets the next retail express order number. The eCommerce order number is copied in tot he External Order number. You can run some reports using this external number and you can see it on the invoice.
So …
