How ONESOURCE Determination can be a part of your business’s technology transformation.

Technological transformation projects can seem daunting, especially for large corporations looking to make a big move like upgrading ERP systems or moving to the cloud. But if that transformation is done without bringing tax to the table early, you can be left with disparate systems that don’t talk to each other, creating more work for your tax team. If your company is looking at new technologies to support run-the-business activities – whether that be a new ERP, ecommerce, or finance system – it’s usually the best time to also talk about your tax needs. ONESOURCE Determination seamlessly integrates with numerous systems on the market today, allowing regulatory updates, jurisdictional changes, and other tax policy data to be added and applied throughout your organization from a centralized, cloud-based hub.

By integrating ONESOURCE Determination with your business systems, you can reduce time, effort, and risk posed by manual processes or disconnected solutions. Plus you can easily apply your tax policy consistently across your business and collaborate across regions with our cloud-native solution.

It was a perfect storm of tax challenges. Instead of being swept up in it, we decided to use it as a basis for transformation.
