With an auditor's eye

Advice from someone who knows what auditors look for.

Many advisory projects only fail at year-end. With my experience as a public auditor, I develop solutions that are audit-proof from the start.

FAQ

Frequently asked questions on consulting

What does accounting advisory mean?

Accounting advisory is advice on financial reporting – for example on complex accounting questions, a conversion to IFRS or Swiss GAAP FER, consolidation or preparing for a statutory audit.

Which accounting standards do you cover?

HGB, the Swiss CO, Swiss GAAP FER and IFRS – including reconciliations between these standards for groups with entities in several countries.

Can you advise me if you are also my statutory auditor?

Only to a limited extent. Professional independence rules restrict advisory services for audit clients. I clarify this transparently with you before every engagement.

Do you work on projects or on an ongoing basis?

Both: from individual questions and projects with a clear scope to ongoing support, for example with the monthly or year-end close.
