The Reporting spaghetti - Simplifying indirect tax compliance without cooking up a whole new kitchen

A peer-level round table with Grant Thornton and Vertex on how tax and finance teams can move step-by-step toward a future-proof indirect tax operating model—without creating “spaghetti integrations.”

Date: Thursday, June 11, 2026
Time: 14:00 - 17:00 followed by optional drinks and dinner

Most indirect tax landscapes did not start as spaghetti. They grew into it.

One solution at a time. One country requirement after another. One workaround layered on top of the next.

Until reporting, determination, and data no longer quite fit together, and everything becomes harder to scale, explain, or defend.

The question is not how to start over.
The question is how to untangle what is already there

Indirect tax, e-invoicing and reporting often grow into a tangled plate of local fixes, point solutions and workarounds. It may work for now, but it rarely scales and becomes harder to explain or defend over time.

This roundtable brings together senior tax and finance leaders to explore how to move from spaghetti to a clearer roadmap. Not by starting over, but by making practical decisions that reduce complexity step by step.

Who should attend

This session is designed for senior practitioners and decision-makers who sit between strategy and execution, including:

  • Heads of Tax
  • Finance and Tax Transformation leaders
  • ERP and IT stakeholders supporting tax and finance

Why attend

You will hear how others are dealing with fragmented requirements, manual workarounds, and ERP limitations, and how they approach e-invoicing as a starting point rather than the end goal.

The focus is on what is realistic, maintainable, and defensible. Combining technology with process, ownership, and change.

This is a peer discussion, supported by experience from Grant Thornton and Vertex.
