When the Plugin “Customer Orders and Delivery Management” is purchased and activated, you can mark a transaction for either “Pickup” or “Delivery” in Tagrain. A transaction marked as “Pickup” or “Delivery” will have the following impact on inventory:
Quantities marked for Pickup or Delivery are reserved and are not available for sales
As the quantities are picked up by the customer or delivered, the reservation is reduced by the picked up / delivered quantity
In case of a Refund the stock on hand is increased by the refunded quantity. There is no change to the reservation (in case the deliveries were partial)
In case the order is canceled, the reserved quantity is reduced to zero, However, there is no change in the stock on hand quantity
