With this add-on you simply enter the project address in DesignSmart, or the ship to address in SmartPOS, and then SmartSalesTax will do the following:
Step 1. It will validate the address is a legal address.
Step 2. If the address is in a state in which you collect sales tax, it will retrieve the current sales tax rates from an online sales tax resource.
Step 3. It will calculate the correct sales tax amount.
Step 4. It will automatically create "Sales Tax Items" in QuickBooks if they are not in the system already.
All these steps are done in real time and happen transparently.
