Freelance Auditor: Temporary audit assurance—without compromising on quality or independence.

Our freelance auditors' profiles review annual and consolidated financial statements in accordance with the German Commercial Code (HGB) and International Financial Reporting Standards (IFRS), evaluate internal control systems, and deliver reliable audit reports, management letters, and internal control assessment matrices. They take responsibility for the entire audit process—from the audit plan to the audit report—and communicate findings directly to the CFO, external auditors, and the supervisory board. For companies, this means access to external audit expertise without the commitment of a full-time employee.


Typical triggers for engaging an auditor include capacity constraints in the internal audit department, upcoming annual financial statement audits, suspected irregularities, or an impending M&A Due Diligence. Regulatory requirements or the implementation of a new internal control system also lead companies to this solution. The sooner you act, the more leeway there is for thorough onboarding and comprehensive audit documentation.

When do companies need an auditor?

Whether it’s a capacity bottleneck in the internal audit department, an upcoming annual financial statement audit, or a specific suspicion of irregularities—our profiles are tailored to handle precisely these situations.
1. Determine the reason for the audit
  • Unclear risks, grounds for suspicion, or unusual financial figures in the accounting records.
  • Audit plan, including audit objectives, scope, materiality, and timeline for the auditor.
2. Evaluate the control system
  • The ICS is not documented or appears inconsistent and dependent on individuals during audits.
  • ICS assessment with a control matrix, process map, and effectiveness evaluation (design and operating effectiveness).
3. Test processes
  • High error rates, data inconsistencies, or lack of dual-control principles in core processes.
  • Random sampling, walkthroughs, and tests of controls, including working papers and supporting documentation.
4. Ensuring compliance
  • Regulatory requirements (e.g., GoBD, ISO, SOX-like controls) cannot be clearly demonstrated.
  • Compliance check with gap analysis, action plan, and supporting documentation for internal/external audits.
5. Prioritizing findings
  • Many individual findings without clear risk classification and without an owner responsible for implementation.
  • Audit report with risk rating, root cause analysis, corrective actions, responsibilities, and deadlines.
6. Monitor implementation
  • Measures fizzle out; effectiveness is not tracked or retested.
  • Follow-up tracking, retesting of measures, and closing statement, including management reporting.

Hard and Soft Criteria for Selecting Auditors

The professional foundation of a compelling auditor is a proven audit track record—ideally from an accounting firm or an established internal audit function. Solid knowledge of the German Commercial Code (HGB) and International Financial Reporting Standards (IFRS) is not a given but must be demonstrated through specific audit projects and references. Industry knowledge plays a crucial role: An auditor with experience in the manufacturing industry brings different areas of expertise to the table than someone with a background in the financial services sector or the public sector.

In addition to professional qualifications, independence and discretion are key selection criteria—especially for special audits or when internal conflicts of interest are involved. An experienced auditor communicates audit results clearly and in a manner tailored to the audience: differently with the CFO than with the supervisory board. A structured approach to work and the ability to document findings precisely even under time pressure are verifiable indicators that are evident in work samples, audit reports, and reference checks.

Warning signs during the selection process: Candidates without verifiable audit experience from an audit firm or an internal audit department, a lack of industry references for the relevant field of work, an unclear or non-reproducible audit methodology, and the absence of concrete examples from comparable special audits should be critically scrutinized—regardless of certifications or general qualification details.

Audit services that deliver measurable results

Our experts assume full audit responsibility for defined audit areas—from financial statement analysis in accordance with HGB or IFRS, through the valuation of provisions, receivables, and inventory, to the review of cost accounting and cost calculation bases. The result is not a general report, but a structured audit report with clear findings, prioritized recommendations for action, and transparent audit documentation.

In the area of internal audit, our profiles review processes, control mechanisms, and compliance structures in accordance with recognized auditing standards. They create ICS assessment matrices, identify control weaknesses, and develop concrete measures to minimize risk—all documented in a management letter that can be addressed directly to management or the supervisory board. For special audits—such as those for fraud detection or forensic accounting—our profiles work with structured audit plans and risk maps that deliver reliable results even under time pressure.

Our profiles coordinate independently with auditors, tax advisors, and internal departments, so that you, as the client, do not have to manage any coordination issues. We ensure that the right profile understands your requirements and is ready to begin within 24–36 hours.

Typical areas of application: From financial audits to fraud detection

An auditor strengthens your governance by conducting structured risk assessments, testing controls, and tracking measures until they are effective.

  • Plans audits using a risk-based approach, defines the scope and materiality, and coordinates with stakeholders in Finance, IT, and functional areas.
  • Evaluates ICS design, tests control effectiveness, and documents evidence in audit-proof working papers.
  • Analyzes processes such as P2P, O2C, Record-to-Report, Treasury, or Payroll and identifies weaknesses and root causes.
  • Prepares audit reports with risk ratings, action plans, responsibilities, and follow-up mechanisms, including retesting.

Frequently Asked Questions

How quickly will we receive profiles of freelance auditors?

You’ll receive suitable profiles within 24–36 hours. To do this, we cross-reference the audit assignment, scope, industry, system landscape, and desired level of seniority with our network. You’ll then receive a brief, clear overview of the profiles, including availability and areas of expertise.

What does an auditor do?

An auditor plans and conducts internal audits, assesses risks, and verifies whether controls and processes are functioning effectively. They document evidence in working papers, formulate findings with risk ratings, and derive specific actions. In addition, they oversee follow-ups and retests to ensure sustainable implementation.

When does a company need an auditor? How can you identify the need?

The need typically arises during periods of growth, reorganizations, system changes, or when audits must be conducted on short notice. Warning signs include recurring process errors, unclear responsibilities, incomplete documentation, or conspicuous discrepancies in key figures and journal entries. With these profiles, you can quickly create capacity while simultaneously establishing structure in audit planning and tracking.

What skills, tools, and certifications should an auditor have?

Key competencies include methodological expertise in risk-based audit planning, evaluation of internal control system (ICS) design, test-of-controls, and accurate documentation in accordance with auditing standards. In terms of tools, Excel, PowerPoint, and common ERP environments (e.g., SAP) are essential; for sampling and analysis, SQL, ACL/IDEA, or modern audit analytics approaches are helpful. Certifications such as CIA, CISA, or comparable qualifications are a plus, as is experience with GoBD, ISO environments, or group-wide policies.

How does an auditor differ from a certified public accountant (CPA) or a compliance officer?

An auditor serves as an internal, independent audit function and evaluates processes, controls, and risks with a view to improvements and effectiveness. A certified public accountant primarily audits the annual financial statements or issues an audit opinion in accordance with external auditing standards and with a different audit objective. A compliance officer designs and implements rules and programs; our profiles review their implementation and effectiveness and provide reliable findings.

What deliverables does an auditor typically provide?

Typical deliverables include an audit plan and audit program, an understanding of processes and controls (e.g., flowcharts, control matrix), and working papers with supporting evidence. In addition, there is an audit report and management summary with a risk rating, root cause analysis, and an action plan including responsible parties and deadlines. Following this, our profiles provide follow-up reports, re-test documentation, and a transparent status update on the completion of the corrective actions.

How much does an auditor cost?

The daily rate for an auditor is typically between €700 and €1,100. The specific rate depends primarily on seniority, the type of audit (e.g., process, ICS, IT-related), industry requirements, and the expected level of documentation. With these profiles, you’ll receive transparent terms upfront that match the scope and duration of the engagement.
