Case Study: Grant Thornton achieves analytics-driven tax automation and faster insights with Alteryx

Grant Thornton - Customer Case Study

Grant Thornton, a global network of independent audit, tax and advisory firms, faced a need to move from spreadsheet-driven workflows to analytics-led processes. Teams required a self-service, non-IT tool that could handle large datasets, reduce manual error, speed delivery, and meet growing compliance complexity (e.g., post‑Wayfair economic nexus rules) across diverse systems like SAP, Oracle and Excel.

Using Alteryx, Grant Thornton built reusable workflows for Wayfair nexus analysis, fixed-asset automation, state apportionment aggregation, and data prep for Corptax and Power BI visualizations. The solution automated data cleansing and transformation, freed staff from manual cut-and-paste work to focus on analysis, improved accuracy and ownership, enabled cross-team sharing through an internal Alteryx community, and positioned the firm for greater automation and AI-driven insights.
