Learned from the ground up, founded for mid-sized companies

Jannik Hassel, German Public Accountant and managing director of justReporting GmbH Wirtschaftsprüfungsgesellschaft

I learned audit and advisory from the ground up at Big Four firms. Over time I mostly managed projects. But I wanted to audit and advise myself again.

So I founded justReporting for mid-sized companies, to be a partner you can rely on.

Three fields, one aim: making it easier for you

Questions before you engage us

What do you mean by “Trust is our craft”?

A German Public Accountant creates trust: you receive a result you can rely on, and authorities, banks or business partners can follow what it rests on. To us, craft means working for it thoroughly in substance and simply in process, whether a legal duty is due or a value is needed.

How do I check whether someone is a German Public Accountant?

In the professional register of the Chamber of Public Accountants (WPK), which is public under section 37(1) WPO. Search by name or register number.

Do you only work for automotive suppliers?

No, they are one focus. For example, we developed a green electricity audit programme and audit the suppliers of ZF Friedrichshafen AG worldwide. We also audit and advise mid-sized companies in other industries.

What does working with you cost?

That depends on the scope and the state of your documents. We clarify both in the intro call; the fee basis is fixed in writing before we start.

Do you also come to us?

Yes, where the audit requires it, for example for a site visit, and gladly for the closing meeting. Otherwise we usually work by video; that saves you time and travel costs.

Why are there hardly any client names here?

The very fact of an engagement is confidential (section 43(1) WPO, section 203(1) no. 3 StGB). We name clients only with their consent and show voices from public reviews without the authors' names, unless they have agreed to be named.

How high is the professional indemnity insurance?

At least 1 million euros per claim (section 54(4) WPO). Insurer and territorial scope are in the legal notice.

What do you not take on?

Legal advice. Where a legal question affects our result, we name it and obtain a lawyer’s assessment.

Intro call, 25 minutes
