The tax calculation automation with Workday, although not perfect, still helps streamline the process. Review collected by and hosted on G2.com.
There seems to be a disconnect between O Series and Vitr. Another issues compliance details and rates aren’t always correct, and the only workaround I’m given is customization. This has been especially noticeable in Louisiana. Updates to the system. Review collected by and hosted on G2.com.

I love how Vertex calculates our sales tax for all of my company's ecommerce orders. I appreciate that as jurisdictions change tax rules and rates, everything is automatically updated in our system. The O-series really helps with our ecommerce sales tax calculation, and it's constantly fluid and updating. It's mostly automated, which means we don't even have to think about it.

I like the interface because it is easy to navigate. I like that when tax rate changes occur, we do not have to make any adjustments or try to keep up on them ourselves. I like that I am able to run reports that give me the exact information I need to reconcile. I like that we can test transactions before implementing them into Production.
