The *advanced settings* in the general section of *order import* settings allow you to configure the following:
1. **Third-Party Return Source**: Xoro supports third-party return processing Shopify apps, namely Loop Returns and ReturnLogic. Based on which app you use, you can choose between the two. If you are not using a third-party app for handling returns for your store, or if you use an app that is not available in the dropdown, you may leave this field blank.
2. **Return SKU Name**: This field allows you to specify the SKU in Xoro that can be used when the returned item in Shopify does not have an SKU number.
3. **Default SKU Name**: This field allows you to specify the SKU in Xoro that can be used when the ordered item in Shopify does not have an SKU number.
4. **Use Default SKU when incoming SKU is not found in Xoro**: When enabled, Xoro will use the default SKU name as the ordered item if the item on order in Shopify does not exist in Xoro.
5. **Duty SKU Name**: If you handle duty charges on your Shopify orders, this field allows you to track them under a *duty SKU* in Xoro.
6. **Enable Tips/Donation Handling**: If you accept tips or donations on your Shopify orders, enable this and specify a tip/donation SKU from Xoro to handle the same.
7. [**Sync Third Party Customer And Company Data With Xoro**](/getting-started/configuring-settings/orders/general/general-advanced-settings/sync-third-party-customer-and-company-data-with-xoro.md)**:** When enabled, Xoro automatically synchronize the customer and company data associated with the order.
