LVK ships orders based on the selected shipping service level (standard, expedited, or overnight), product availability, and order hold status.
Reasons a New Order May Ship First
Shipping Service Level
If an order with standard shipping imports to LVK on Dec 10 at 11am, and a second order with expedited shipping imports at 12pm, the newer order may ship first so it can meet its SLA.
Order Status
Order Hold
An older order with a hold may not ship, which lets a newer order ship first.
Ready to Ship
LVK only sends orders with a "Ready to Ship" status to the shipping queue. Any other status, including On Hold or Not Ready, keeps the order out of the queue. This can explain why LVK processes a newer order before an older one.
Reasons a New Order May Be Picked First
LVK warehouses use multiple methods for processing orders, depending on order volume, inventory velocity, and labor efficiency. Sometimes LVK picks orders individually; other times, it processes them in bulk.
Because of this, a newer order may be fulfilled before an older one. This is a normal part of warehouse management, and it helps LVK meet shipping SLAs on time.
