The term Batch is used in ShipStation to indicate a set of orders meant to be processed as a single group. In ShipStation, batches are primarily used to process multiple orders at once, which can greatly enhance your shipping efficiency. Batches can also act as a temporary storage location for orders that are ready to ship.
For example, you would want to use a batch when you have several orders contained in different views or on different pages that you’d like to ship together. Adding them to a batch allows you to view them altogether, then create labels for them all at one time.
An added benefit is that when a batch is processed, ShipStation sends shipment notifications to your selling channel with a single notification for all orders in the batch. This can be greatly beneficial if your selling channel has limits to how many notifications it will accept in a specific time frame. Because of this, batching is highly recommended when processing Amazon orders.
