Some inventory items have special environmental fees or taxes which need to be applied with the product is sold. For example, selling a petroleum product may require a Solid Waste Tax or Fee be charged. Typically the fee is based on quantity rather than selling price.
Other examples would be special fuel taxes, recycling fees, surcharges, and more.
Rather than attempting to set a special tax rate, we recommend a TAG-ALONG inventory item which will charge an appropriate fee equal to the quantity sold. When it is time to report sales and waste fees collected, you can run a Dept/Category Sales report filtered for the specific category and date range.
1) Create a category for your petroleum products
2) Add oil inventory items to that category
3) Create another category for your Solid Waste Tax
4) Add Inventory Items for your Solid Waste Tax and put them in the Solid Waste Tax category. These items will not charge tax, nor track stock.
5) Add a Solid Waste Tax Tag-Along item to the Oil Inventory Item and choose "Use Main Item Quantity" with the "Fixed Quantity" set at zero
6) You will be able to do run a Dept/Catg Sales report on the "Solid Waste Tax" category
