Woocommerce and Handling Fees

I’m in a unique situation with my Woocommerce site.

I need to add a packaging fee, which will be somewhat similar to a handling fee.

Unfortunately, it’s not as simple as adding a $5.00 handling fee to every order.

Since I sell wood products based on their measurements (width x height), the packaging fees are based on the total square footage for items. And they can differ depending on the category of the items, as well.

I’ve done a ton of research and I can’t find a plugin to handle this situation.

To add to the complexity, there’s a whole table that would need to be created. For example, if items from one category have a total square footage between 1-10, then the packaging fee will be $10. If total sq ftg is between 11-20, then it’ll be $20.

Is the code for something like this complex?
