“The ONESOURCE Tax Provision model has proven to be easy to use and to standardize the input and output process. The biggest advantage has been the ability to make changes quickly and run what-if scenarios. The best part of the implementation was the department took the time to upgrade and standardize the provision process. It also set up by account tax basis balance sheets, which are now updated twice a year. I would definitely recommend ONESOURCE Tax Provision and have encouraged others that are still using excel to consider the product.”
