Does this place the order automatically?

No — it drafts and requires human approval by design, to avoid accidental over-ordering.

Can I combine items from the same supplier?

Yes — group by supplier in the Code node to create one combined PO instead of one per item.

Inventory Reorder Trigger

Every morning, this scans your inventory, drafts a purchase order for anything below its reorder threshold, and emails procurement to review and approve — turning 'someone should reorder that' into an automatic draft waiting for a sign-off.
