AI for audit firms
We help auditors and tax advisers use AI in audits and financial statements so that audits become more efficient and stay compliant with professional rules.

Firms that want to serve a growing audit market with fewer professionals must embed AI deliberately in audits and quality management.
In numbers
41 %
of audit firms’ digitalisation budgets go directly into AI
52 %
of German public auditors are 55 or older
59 %
of firms say clients expect digital applications as standard

What audit firms are dealing with today
Five bottlenecks and where AI comes in.

A lot of reading before the audit
AI summarises the client’s minutes, contracts and documents and flags possible risks.
Receipts and journals
AI matches invoice, delivery note and payment and flags anomalies in the journal.
Tight deadlines at year end
AI checks the notes against the prior year and the audited figures and drafts sections of the report.
Knowledge in a few heads
When experienced professionals retire, their knowledge stays in the firm. Audit manual, standards and guidelines become searchable, with the source.
Obligations under the WPO and the EU AI Act
We create the AI policy and AI inventory for your quality management system and check every tool against § 50a WPO.
Your challenge is not on the list?
In a free 30-minute AI conversation we clarify whether and how AI can help.
For complex questions with a significant impact on the result, AI serves as a plausibility check. The judgement is the auditor’s.
What we do
From priorities to operations, relentlessly focused on impact.
AI Strategy & Consulting
We show where AI pays off in your audits. Together with you, we set the rules.
AI Design & Development
Assistants and AI agents that match receipts and analyse documents. The judgement stays with the auditor.
AI Support & Evolution
We run your applications, measure their impact and train audit teams.
Our methods
Four building blocks we use to set up every AI project.
Open Model Stack
Technology-agnostic: The right model for each task, without being tied to one provider.
Value Map
Every task rated by value, effort and risk. The result is a clear order of priorities.
Build & Run
One team from strategy to operation. We also run our own software.
Human Gate
Anything that goes out or prepares decisions is checked by a person.
What professional rules require
§ 43 WPO
Conscientious and independent
Understand how a tool works before using it. The auditor remains responsible for the result.
§ 50a WPO
Service providers
Client data only goes into tools whose provider is bound to confidentiality and does not train on the data.
§ 51b WPO
Documentation
For significant results, the tool, version, inputs, outputs and assessment belong in the working papers.
Under the EU AI Act, AI in audits is usually not high-risk. Article 4 on AI literacy applies to every firm that uses AI.

Frequently asked questions
Where do we start?
With the potential analysis of one audit process. After one day you know where AI pays off and where to start.
May we enter client data into AI tools?
Only into protected systems: The provider is bound to confidentiality under § 50a WPO and demonstrably does not train on your data. Otherwise only anonymised or pseudonymised.
Can an AI result serve as audit evidence?
For simple matters and suitable applications it can be sufficient. For complex questions it usually only serves as a plausibility check. Responsibility stays with the auditor.
What do we have to document?
Who used which tool for which audit procedure with which result. For significant results also the version, inputs, outputs and your assessment. Reproducibility is not required.
Do we need our own AI policy?
Yes. The WPK expects a deliberate decision by the firm’s management and rules in the quality management system: Responsibilities, approved tools, training. We create it with you.
What does the potential analysis cost?
Prices are not shown on the website. On request we give you an indication, and the proposal then states a fixed price.
