When inventory is replenished after stockouts, you can use FIFO (First In, First Out) order allocation to ensure your oldest orders are prioritized for fulfillment. Jetpack offers two FIFO strategies to help you manage how inventory is allocated to orders waiting in Exception status.
How Order Allocation Works
Inventory is assigned to orders when they are imported and set to Processing status. If there isn’t enough inventory at a single fulfillment center to complete an order, the order is moved to Exception status. Orders in Exception reprocess every 30 minutes. However, once inventory is replenished, newer orders may receive the available inventory before the older Exception orders are reprocessed.FIFO Allocation Strategies
Jetpack offers FIFO rules for merchants that need to prioritize older orders over newer ones. There are two mutually exclusive approaches:- Full Allocation
- Partial Allocation
Allocate Oldest Orders First
Once all of the previously out-of-stock inventory is replenished, orders with the oldest Purchase Date in Exception are released before newer orders. If the Purchase Date isn’t available, the Import Date will be used instead.Orders with the oldest dates remain in Exception if full inventory is still unavailable.| Aspect | How It Works |
|---|---|
| Priority Logic | Orders with oldest Purchase Date (or Import Date if Purchase Date unavailable) are released first |
| Allocation Requirement | Full inventory must be available to fulfill the complete order |
| When Orders Stay in Exception | Orders remain in Exception if full inventory is still unavailable |
| When Orders Move to Processing | Only when all items in the order can be fulfilled from replenished inventory |
