Why It Matters

Tax Firm Work Still Breaks Across Too Many Systems

In many tax firms, valuable time is lost before the professional review even begins. Employees collect DATEV data, documents, register information, and internal context manually.

Scattered Information

Client data, accounting information, documents, and tax knowledge often live in different places. Teams spend too much time searching, checking, and asking around instead of completing work.

Manual Follow-Up

Recurring reviews and preparation tasks are still started and tracked manually in many tax firms. That creates avoidable overhead and slows down turnaround times.

Knowledge Bottlenecks

When important operational or tax-related know-how stays in the heads of a few experienced employees, the rest of the firm becomes dependent on interruptions and internal back-and-forth.

How It Works

From selecting a solution to reviewing its result

The tax firm selects a solution and defines its scope. Klarvos completes the task and records the execution. The firm does not need to design a workflow.

Select

Choose a maintained solution

Choose the concrete task Klarvos should complete, such as preparing a client meeting or reviewing open items.

Execute

Klarvos performs the execution

Klardaten manages DATEV access, execution state, retries, and the exact solution version.

Review

Review the result where you work

The result can be presented through Klarvos or a supported external application. Source references and execution details make the result understandable before the next decision is made.

Security & Deployment

Controlled execution for sensitive tax-firm data

Klarvos keeps data access, execution, and results within a defined operating model. Write operations are limited by permissions and solution rules, can require approval, and are recorded for audit.

Access under clear rules

Each execution uses the connected DATEV context and the permissions assigned to it. A solution can read or change data only when its permissions and rules explicitly allow it.

Hosting in Germany

Klarvos is hosted in Germany. This aligns the data location with the security and compliance requirements of many tax firms.

Traceable results

Findings are returned with their source context and the relevant execution details so the tax firm can review them before acting.

Traceable versioning

Every execution records which version of the solution was used, keeping changes to the solution logic traceable.

Existing DATEV connections

The technical foundation is already used in production

Klardaten is used in live operations where stable DATEV connections and low administrative overhead matter every day.

The interface is incredibly stable, and the admin effort for managing DATEV connections has dropped sharply.
