Whiplash ships the oldest in-stock orders first. This puts multi-item orders at a disadvantage and can cause them to be skipped for single-item orders when:
- An item unintentionally oversells
- An inventory adjustment is required, resulting in the item being oversold
- Items come into stock one at a time, but never all at the same time
This can be solved by automatically splitting orders to ship what’s available now.
The definition of Reserved might be helpful here– the Available/Webstore inventory has been reduced to reflect the order, but there is no process to physically set the stock aside.
