Never Diminishing Products are product codes in Unleashed that do not require physical inventory to be stocked. These are used for commonly incurred charges such as freight, taxes, or shipping fees.
Go to Inventory | Products | Add Product. For more information, see Create New Products.
Click Details and select the Never Diminishing check box.
The Purchase Account (Expense) field will be displayed. If you want to purchase a Never Diminishing Product, you can select a value from the Purchase Account drop-down list. Click to expand (screenshot).
If you have integrated with an accounting provider, the Sales Account and Expense Account fields will be displayed. If you add Never Diminishing products on a Bill of Materials, Assembly, or Disassembly, you must select a value from the Expense Account drop-down list.

If there is a cost involved in providing a Never Diminishing product (e.g. labor costs), but you do not not want a 100% margin displayed on your sales orders, you can edit the Last Cost of the product which is what the margin will be based on.
