The concept of partial fulfillment is to allow the store admin to fulfill the partial orders if the inventory for all of the products in any order is not available at that given point. Partial fulfillment gives you finer control over the way you ship your orders to your customers. It allows you to divide your order into one or more parts that can be shipped independently. You can also create invoices for partial fulfillments.
Go to the Settings > Shipping Settings section in StoreHippo Admin Panel to enable the partial fulfillment.
Select the Enable Partial Fulfillment checkbox.
After selecting the checkbox, click the Save & Continue button to save the setting.
When you enable the Partial Fulfillment feature in your Admin Panel, you have access to the Fulfillments section under Orders.
