Performance counts.
To us and to you.

What we achieve for you is best summed up in our daily misson. We don’t just want to satisfy our clients. That is simply not enough for us. We want to inspire them.

We see the people behind the numbers.

We see our profession as being much more than mere formulas and number crunching: behind every financial goal, we see people with dreams, plans and ambitions. Throughout all our tasks and assistance, we focus on the people behind the facts and figures.

It’s plain and simple.

We are good at talking “number talk”. However, we don’t assume that everyone speaks it fluently; we translate and interpret it for you!

We’re one step ahead!

We are proactive; we don’t wait for clients to contact us. We advise and update them with relevant information, as we see fit.

Our services, step-by-step:

  • Bookkeeping & cost accounting
  • Payroll & employment law consulting
  • Annual financial statements & tax returns
  • Tax & business consulting
  • Audit & other audit and assurance services
  • Representation at financial investigation proceedings

A team that's on your side.

To be precise: your success is our job. Everyone at IWTH has only one thing in mind: to optimize your performance. We take tax and financial matters off your hands so that you can target your core business.
