Two improvements make it easier to stay on top of what is on order and when it will arrive.
The product and variant details page now includes a Purchase Orders tab listing all open, incoming PO lines for that variant. Each row shows the PO number (linked directly to the order), the supplier, the quantity ordered, the quantity still outstanding, and the expected delivery date, sorted by ETA so the nearest arrivals are at the top. Fully received lines and closed, draft, or deleted purchase orders are excluded. When nothing is on order, an empty state makes that clear.
This means you can see at a glance what stock is on the way and when, without leaving the product page or cross-referencing your purchasing list.
The estimated delivery date on a purchase order is now editable even after the order has been billed. Previously the field was locked once billing was recorded, which made it difficult to update an ETA when a supplier's timeline shifted late in the process.
