What our customers have to say:

“Before switching to Sales Tax Systems we had used another provider. We found that there were issues with missing zip codes and incorrect tax rates in their file. When we notified them about the errors, it took weeks to get these issues fixed. With Sales Tax Systems we have found that the zip codes and tax rates are extremely accurate. If we do have a question, they are very responsive.”
