Backorders, partial fulfillment and available to promise

When an order comes in short on stock, ship what's on hand and hold the rest as a tracked backorder. It shows up on your reorder list, turns into a linked purchase order in one click, and closes out when that stock arrives.

• Fulfill a short order and it ships the units you have, then holds the shortfall as a backorder instead of quietly selling stock you don't own.
• Backordered items get their own section on the reorder list, even for products you don't normally keep on hand.
• Turn a backorder into a purchase order in one click. It stays linked, so anyone in buying or reports can see it's handled.
• Receiving that purchase order closes the backorder, and the final units ship when you're ready.
• Confirmed orders reserve stock, so availability always reflects what's already promised and you never oversell.
• Kits reserve their components, so bundles never oversell a shared part.
