If you want to see shipping charges as a line item on your Revel operations report:
On Revel, find the shipping product ID, which is the numeric ID from the URL of the product. For example:
https://yourdomain.revelup.com/menu/products/1842/detail/ the product ID would be 1842.
On Vines OS, go to Revel > Establishment and enter the Revel product ID in the field "Shipping service product ID"
