Do all of your addresses in your CRM have the Zip code +4 digits (also known as the 9-digit zip code)? In most cases, they do not. This is required to retrieve the most accurate Sales Tax information for the address you are quoting. QuoteWerks can now do this for you. There is no need to select from a list of tax rates because now you will have the tax rate for that specific address rather than just the 5-digit postal code.
