Reservation value is required if you enable Magento Orders creation option in eBay Integration > Configuration > Accounts > Orders.
Note: Reserve Quantity option is not available if Immediate creation of Magento order is selected in Create Magento Order When option
How it works? The mechanism is simple:
- eBay Order is imported;
- Magento Product's quantity is reserver (so it is decreased) until Magento Order is not created;
For example, you have a Product listed on eBay with QTY=12. In account settings you set to create Magento Orders after Checkout is completed and Payment is received.
2 Items were bought on eBay and eBay Order is imported. However, this order is not paid, so Magento order is not created yet.
- If quantity reservation is disabled - on eBay there are still 12 items available for purchase. But physically 2 of them are already sold. As a result - you can sell them again and it causes overselling.
- If quantity reservation is enabled - the Product QTY is reserved, so there are only 10 Items available on eBay. As a result - these items are not available for buyers and overselling is prevented.
In case you order was Reserved but then canceled, the reserve quantity will be released and becomes available for buyers again.
Default Quantity Reservation period is 1 day. So if 1 Item was bought and Magento Order was not created, Quantity will be reserved, so in Magento it will decreased and overselling will be prevented.
How long Product QTY will be reserved?
The reservation period you set up in Account settings - is the maximum period for Reservation.
The Reservation can be canceled after Magento Order creation or manually by click Cancel QTY Reserve button at the top of the Order page.
After the product quantity is released, you can see an according record in Orders Log.
