Connect your ERP system to manage global transaction tax

Determination delivers billions of real-time tax decisions at the point of transaction, directly to your existing Dynamics GP platform. Because it seamlessly works with your existing sales and purchasing processes, you can better manage global tax requirements and get a more complete view of your tax liability.
