I help senior tax professionals at multinationals regain control in the era of SAP S/4HANA, AI, and real-time digital compliance.
Sr. ERP Tax Solutions Architect · London, UK
Tax outcomes are now determined upstream — by data flows, system configurations, and architecture decisions made by people who don't think in tax.
"I lost two people to the Big 4. I've been trying to backfill for seven months. The work hasn't gone away — it's just been redistributed onto the people who are still here."
— Indirect Tax Manager, multinational corporation"I'm expected to lead a digital transformation I wasn't trained for. My Head of Tax told me we need to 'lead the tax technology transformation.' Great. Where's the training? Where's the budget?"
— Senior Indirect Tax Manager, global industrial companyTax leaders aren't failing because of poor judgement. They're applying a legal interpretation mindset to a world where outcomes are determined by system architecture. Nobody trained them for that shift.

Richard de Bie
Director Global Indirect Tax
I began my career in IT before combining it with tax — first at Cisco Systems, where over 18 years I designed and built the global VAT/Sales & Use tax solution that still underpins tax determination on a $45B+ taxable basis annually. I later founded an international boutique consultancy that was acquired by Ryan Inc. in 2015.
Today I work independently — advising tax functions, training the next generation of tax technologists, and building TX Operating Logic: a structured way of thinking about how tax functions should operate in a world shaped by AI, real-time reporting, and enterprise systems.
I'm a recognised thought leader: published in the International Tax Review, a guest lecturer at WU Vienna's LL.M. in Digitalization & Tax Law, a presenter at the Tax Executive Institute, and Europe's first Black Belt Taxologist.
