Tap a transfer to preview it, or tick several and create them all at once. Use Load all that need invoicing to pull the entire backlog (or Load older transfers to page 50 at a time), and Only ones needing invoicing to hide the ones already done. Any batch asks you to confirm the count before it creates real Zoho sales orders. PO numbers are matched automatically from Shopify; everything lands already Confirmed, and duplicates are blocked.
