Building a better working world
"Businesses must change their tax functions in a rapidly changing society. To prepare for change, I advise companies on how to build their internal processes, and contribute to strengthening company functions by taking on business outsourcing as an external provider.
It is also essential to automate routine operations for tax functions: we need to become pioneers of automation and I am working to share this knowledge with client companies."
