There is no effort involved, just that fee.

Nice, you don't have to report what was sold (is there a tax on this particular product in this particular jurisdiction, sub-jurisdiction, or sub-sub-jurisdition??? Do they just guess?) How much it cost, who it was sold to, when, what was the shipping address, was it the same as the billing address, else how can they tell if there's a separate tax for that jurisdition?

God help you if your data entry clerk (that you had to hire to track all this crap) makes a data entry error.

That's a service that is easy to automate. You don't have to do much, just enter the amount and the zip. The types of products you sell might not be taxable in some jurisdictions, but except for food that's probably a red herring. Most small online companies sell products that are taxable everywhere.
