What it shows

  • Reservation states separate available from physically on-hand stock.
  • Packing transitions items from soft allocations to final depletion.
  • Order cancellations cleanly revert reserved counts back to available.

The takeaway

Decoupling stock availability from warehouse fulfillment states eliminates overselling in flash sales.
