Tax consulting is undergoing a profound digital transformation. At the heart of forward-looking concepts are tax firm software programs. They provide the necessary tools to manage clients, employees, and work processes, ensuring structure and transparency.

Workflows increase efficiency, simplify collaboration within the tax firm, and optimize communication with clients. Through the automation of repetitive processes, tax firms gain capacity for expertise and individual advisory services.

DATEV is considered an industry leader, yet alternative software providers for tax advisors are gaining increasing significance. All systems offer similar core functions but differ in scope, pricing structures, and present various advantages and disadvantages.

What is tax advisor software?

Tax advisor software are programs with which all typical activities of a tax firm can be handled digitally. Operational processes are centrally controlled and run automatically. The functions are diverse, ranging from digital collaboration within the team and with clients to task and appointment management, time tracking, and invoicing.

Typical areas of application for tax firm software are:

  • Financial accounting and bookkeeping

  • Payroll and salary calculations

  • Tax returns and annual financial statements

  • Client and document management

  • Task and deadline management

  • Client portals for secure data exchange

  • Workflow automation for recurring processes

  • Reporting and evaluations

In contrast to conventional tax software for end users, tax advisor programs are specifically designed for professional service providers and their complex requirements.

Advantages of tax advisor software

The use of modern tax firm software offers tax firms a range of strategic and operational advantages. Automated processes in accounting, payroll, and deadline management make work processes efficient and save valuable resources:

Time Savings: Time-consuming and repetitive tasks are automated, allowing tax advisors to focus more intensely on consulting activities.

Transparency: A central platform facilitates both internal communication and interaction with clients. Data can be accessed anytime, regardless of location.

Error Minimization: Plausibility checks and automatic controls improve quality and reduce human errors. The software sets reminders and checks entries for completeness.

Client Satisfaction: A client portal allows secure, quick exchange and promotes digital collaboration.

Legal Compliance: GoBD-compliant archiving and interfaces to tax offices support adherence to legal requirements.

Functions and modules

Modern tax advisor software is far more than just a digital tool for accounting today. It forms the organizational backbone of entire tax firm management. Current solutions offer a broad range of features designed to meet the demands of tax firms and ease daily work processes.

Project and task management

Modern tax firm software enables clear and efficient planning of work processes. Tasks are assigned clearly, the filing is traceably designed, and insight is provided into ongoing projects. An overview of task and project management ensures transparency and planning security throughout the tax firm.

Employee management

Efficient team management is a central success factor. A tax advisor software facilitates internal collaboration, enables structured onboarding of new employees, and supports the precise assignment of tasks. Individual access rights and simple user management must be ensured.

Workflow automation

Workflow automation is a core element of modern tax firm administration. Recurring processes such as client reminders, deadline monitoring, or document processing can be automated. Processes are standardized, errors minimized, and valuable time freed for consulting.

Document management

An integrated document management system (DMS) is crucial to reducing paperwork and optimizing workflows. A powerful solution offers features like secure storage, electronic signatures, document sharing, and precise rights management. All documents are archived in compliance with GoBD and are available digitally at any time.

Client management and client portal

A modern client portal is now an indispensable part of a digital tax firm. Clients can securely upload, view, and electronically sign documents. Additionally, the portal enables direct communication with the tax firm and simplifies payment processing, resulting in efficient, seamless exchanges between client and tax firm.

Time tracking and invoicing

Time tracking and transparent invoicing are basic functions of modern tax firm software. Time expenses can be accurately documented, expenses recorded, and invoices automatically created based on this data. This increases traceability and saves administrative effort.

Reporting and controlling

Powerful systems offer extensive reporting functions, enabling data-driven tax firm management. Whether predefined report templates, custom evaluations, or financial metrics—the software provides a clear overview of clients, teams, and tax firm results.

Pricing

The cost of tax advisor software can vary significantly depending on the provider, scope, and service model. Entry-level solutions often start around 50 euros per month for smaller modules or basic functions, while comprehensive complete systems require correspondingly higher investments.

Implementation and support

Before introducing a new solution, the onboarding process should be thoroughly reviewed. A structured implementation process, expert guidance, and reliable support greatly facilitate the transition and ensure seamless integration into existing tax firm structures.

Interfaces and integrations

A powerful software seamlessly incorporates data from existing tax or accounting systems and offers interfaces to relevant applications like email clients, schedulers, CRM, or invoicing systems.
