We use it. Services are taxable in Texas and Florida. Since we have employees working from their homes in those states, we have nexus. In some states, if you go to the state to render services, you are considered to have nexus.
If you look at all the tax classes defined in Avalara, it will make your head spin. Last I looked there were over 5,000 different ways to classify things; from software (prewritten, resold, custom developed, etc), services on software (each category previously listed), hardware (timeclocks, routers, pc's, etc.) All those codes exist because one state or county or municipality in the US handles it uniquely.
It was fun setting up the labor and item codes in our accounting system to handle it all.
The alternative approach is to not report at all and hope they never find you.
