You can mark your orders as shipped by following these steps:

1. Log into your 2Checkout account.
2. Click on the “Shipping” tab, then click on “Mark As Shipped” subcategory.
3. Locate the unshipped order in the unshipped sales list or use the unshipped sales search tool.
4. Confirm that the shipping method is correct
5. Enter in the tracking number (or other text, if this does not apply).
6. Choose to notify the customer or not.
7. Add comments, if you like.
8. Click the “Mark shipped” button.

Please note that if your products are not defined as tangible (many custom/third party carts do not define products as tangible), you are not currently required to mark orders as shipped.
