A fulfillment service is a third-party organization responsible for fulfilling shipments for orders generated in ChordOMS. Examples of fulfillment services that ChordOMS supports are ShipHero, EasyPost, and OrderDesk.

Some products do not require physical or digital fulfillment. One example would be when a merchant collects donations for a charity. ChordOMS features a special fulfillment service called Auto-ship to handle these situations.

When an order is completed, shipments fulfilled by the Auto-ship fulfillment service will be automatically marked as shipped when the scheduled fulfillment job runs. Note that this means that shipment will not be marked as shipped immediately after the order is completed; it will remain in Ready state until the fulfillment job has run. Normal fulfillment workflows, such as sending an email notifying the customer that their package has shipped, will be completely bypassed.

The Auto-ship fulfillment service is compatible with all existing shipping methods. Merchants are not required to create a specific shipping method for auto-shipped products unless they wish to prevent customers from being charged the fee associated with the other shipping methods.
