Additional margins to cover operating costs
You can configure automatic additional margins for inventory item categories. They will help you to cover your shop's operating costs. For example, they could cover administrative costs such as internet, telephone, paper, and printer ink or shop materials such as grease and acetylene.
Configure additional margins
To configure additional margins, when creating or editing inventory item categories, enter the percentage in the Percentage (%) for additional margin field.
Use additional margins in the Point of sale
After having configured the automatic additional margin for a category, each time you will add inventory items contained in this category on estimates, the margin will be added to the sale price. However, if you need not to add it, hit the Left arrow key on your keyboard instead of Enter when the field corresponding to the Price column is highlighted.
