Calculate a seperate fee in checkout

[sstottelaar]

Hi,

I’m building a shop in that sells heavy electronic equipment. In the Netherlands, we have a required “disposal fee” (an additional tax) for electronics, which is calculated based on factors like product weight. Each product has a unique disposal fee, and my client would like this fee to appear separately at checkout rather than being included in the product price.

I’ve considered creating a computed field to add the disposal fee to the product price, but this would mean the fee isn’t reflected in the cart’s total calculations. I also thought about extending the tax engine to include the disposal fee, but this could interfere with the tax calculations. An extra line item would also suffice, but that requires a lot of custom work (I think) in the process of adding/removing items from the cart.

Does anyone have suggestions on the best way to handle this? Any help would be much appreciated!

The easiest way would probably be to add the "disposal fee" as a line item, then you don't have to mess around with getting the grand total to reflect your extra total.

You could maybe listen to the OrderSaved event, check that the disposal fee line item hasn't already been added, and add the line item programatically.
