Automating the Tax-Procurement Interface

  • August 03, 2021

As most tax leaders are only too well-aware, the tax and procurement interconnect generates a level of complexity that can place a serious strain on the native tax functionality in ERP and procurement systems. That means lots of work for tax departments. This explains the attraction of a tax engine that can cut through the complexity and control all tax determinations and calculations throughout the procure-to-pay process. 

But the gains aren’t limited to the tax department. Automating the tax-procurement interface delivers beneficial impacts for a wide range of stakeholders. For example, it can improve the financial statements. When tax errors occur with any frequency, finance and accounting teams tend to post larger reserves to cover underpayments and potential audit penalties. Heightened tax compliance accuracy gives them the confidence to reduce the level of reserves they maintain. Improvements in the accuracy of tax payments can also free up working capital.

The most exciting opportunities, however, are the ones that open up for the procurement department. Tax engines apply the same transformative technologies that procurement teams have seen in their own software platforms, including advanced analytics, artificial intelligence and machine learning. My colleague David Deputy, Vertex Director of Innovation, points out that “these advances remove even more manual tasks from procurement while enhancing human activities and decision-making. It essentially equips procurement professionals with a robo tax advisor that helps them do their work.”

Procurement leaders are in a position to ask some exciting questions, such as:

  • How can advanced tax tools be harnessed for analytics that improve sourcing and pricing strategies?
  • Which facets of the P2P cycle would benefit most from a robo tax advisor functionality?
  • What process changes and improvements will help us optimize advanced tax technology?

It’s this type of cross-organizational impact that makes tax automation such an exciting move, as David notes: “These technologies enable a tax department to become more efficient while more effectively serving other corporate functions.”
