I was skeptical at first hearing about how they could get us caught up and in compliance in nearly 17 states. I had been working on voluntary disclosures with another company for nearly a year with little to no success. This meant they needed to step in and handle over 10 voluntary disclosures, registrations, and back sales tax filings. Immediately we had a team in place, and we were off and running exchanging data and ideas. Within 2 months, nearly all of the voluntary disclosures were taken care of! Our dedicated service rep is in constant communication on our monthly and quarterly filings

  • Why does the software use latitude and longitude instead of Zip code or Zip+4?

    ZIP codes and even ZIP+4 areas were created for mail delivery, not tax compliance. Tax jurisdictions often cut across ZIP code boundaries, which means relying on them can lead to inaccurate tax calculations. By using latitude and longitude, our proprietary GIS method pinpoints the exact location of the transaction, even in remote areas, ensuring the correct tax rate is applied.
