Rapid Testing

Test Your Tax Engine In Real-Time

However much indirect tax testing you do, it's never enough. So do more. Rapid Testing is the answer. Now you can automate thousands of test cases, custom scenarios, and configuration settings you didn’t even know about. Fast, powerful and effective. Find out what passed, what failed, and why.  Real time analysis and powerful filtering drive you to highly effective outcomes. For ONESOURCE, Vertex and Avalara.

Work One of Two Ways:

Intelligent Automation

Automatically generate both the test cases and predicted results in minutes.

Custom Configuration

Custom test utilizing any of the data points and attributes within your tax engine.

What Passed. What Failed. Why.

You can see the details that we sent to your engine, and you can see all the information it returned. Line by line, invoice by invoice. You can create some incredibly complex and valuable tests that could form a key control and a key part of your tax governance strategy.



Nothing stays the same. Your ONESOURCE, Vertex and Avalara configurations and solution design will continue to evolve as your business changes over time. You’ll be applying product updates, installing content updates, and deploying integration updates as your tax engine vendor releases them. You might expand into new countries. You might acquire a new business. You might launch new lines of business or manage changes in your supply and distribution chain.

So, how do you know everything still works and you’re getting the tax results you expect? And how do you know you’re getting those results for the right reasons?

And wouldn’t it be great if you could create powerful master tests? Or schedule those master tests to automatically run and periodically notify you if the results are different than before—for every country and location where you do business? Now you can!
