@NShort good question on shipping! We do have a path for this, but you’re correct to say that you cannot use the one-time fee adjustment because we currently do not support tax categories on those. Instead, to add a shipping line we recommend:
- Creating a product (or adding a custom line item) with the name Shipping and assigning it the ‘Shipping’ tax category. We will validate that there is only one product included with the ‘Shipping’ tax category.
- Additionally, note that at least one additional product or line item must be added
Then, on creation, tax will be assessed for all items and the shipping charge. There are actually a number of states where the shipping fee may be taxable.
