End-to-end solutions for SAP: From document to authority

In an increasingly digitized tax landscape VAT reporting is far more than simply filling out forms. For tax managers, the challenge lies in managing the enormous data complexity of modern SAP systems.valid messages to transform. With kallman's support, you ensure that your reporting processes are not only automated, but above all materially correct and procedurally stable.

Holistic implementation of technical reporting solutions

We provide comprehensive support in the Implementation of technical reporting solutions – regardless of whether you are in favor of the top dog SAP Document and Reporting Compliance (SAP DRC) or choose an alternative solution. Our focus is on fully meeting all legal requirements, including the VAT return (UStVA), the annual VAT return as well as the Summary Report (ZM).

The entire data chain in focus

What sets us apart is the consistent consideration of the entire data chain. A valid report is only as good as the data quality at its source. Therefore, we monitor the process from the transactional level – i.e., the correct determination of taxes and data collection in the SD, MM and FI modules – from consolidation in reporting tools to secure electronic transmission to the tax authorities.

Transparency and security for tax audits

Our goal is to eliminating media breaksand manual correction efforts in Excel shadow calculations to replace them with system-supported controls. We ensure that all reportable information is generated directly from your SAP standard or from additional solutions implemented by us. This creates a high level of security for you. Transparency and auditability so you can face tax audits with confidence. With kallman, your reporting becomes a reliable reflection of your tax-related business transactions – efficient, digital and legally compliant.

Legally compliant e-invoicing processes in SAP: More than just a data format

The introduction of mandatory E-invoicing in the B2B sector. This presents companies with a fundamental challenge: the transformation of paper-based or simple PDF processes into structured, machine-readable data sets. At kallman GmbH, we support you in understanding these legal requirements not only as an obligation, but as an opportunity for automated, legally compliant processes in your SAP landscape. We bridge the gap between tax regulations and technical implementation.

Implementation tailored to your requirements: SAP DRC or alternatives

In terms of technological implementation, we align ourselves entirely with your requirements and your IT strategy. Whether it's the implementation of SAP Document and Reporting Compliance (SAP DRC) or the use of tailor-made alternative solutions. We configure the necessary scenarios for national and international requirements. Our goal is a seamless and needs-based connection that perfectly matches your individual circumstances and strategic objectives.

Technological expertise for transmission

The challenge with e-invoicing often lies in the "last mile" of transmission and correct data mapping. We provide targeted support for the following technical topics:

• Format conversion: Creation of legally compliant XML formats such as XRechnung and CUFFED.
• Network connectivity: Integration of Peppol-Interfaces for the secure exchange of invoice data.
• Interface management: configuration of the SAP Integration Suite (on the SAP BTP) or API-based connections to government platforms.
• Monitoring & fault handling: Setting up central dashboards to monitor the transmission status directly in SAP.

Data quality as a success factor

An e-invoicing process is only as stable as the underlying master data and tax logic. We ensure that the transactional data of SD and FI modules apply a correct validation right from the start. Only an error-free data record guarantees successful transmission without rejections from the recipient or the tax authorities. With kallman, e-invoicing becomes an integrated component in your SAP process chain – efficient, scalable and future-proof.

Are you ready yet?

More and more companies are recognising the potential of automation to make their VAT processes in the SAP system more efficient, secure and future-proof. However, before concrete solutions are implemented, it is crucial to check and optimise the existing requirements.

A foundation for automated processes

The kallman team supports you in creating the basis for successful digitalisation and automation of VAT processes in the SAP system. With our readiness check, we identify potential weaknesses and optimisation opportunities in your master data, processes and organisational workflows.

• Analysis and optimisation of master data quality (e.g. business partner and material classifications as well as tax codes)
• Analysing existing business processes with regard to triggering VAT-related facts.
• Identification of gaps or weaknesses in the reflection of tax requirements in the SAP system.

Our team of consultants will provide you with clear recommendations for action so that you are well prepared to take the next steps in the digitalisation of your VAT processes.

Full flexibility

An SAP system offers extensive customisation options and allows companies to design individual business processes. As a rule, customisation entails adapting the VAT processes to ensure that all legal requirements are mapped correctly and efficiently. In addition to adapting the configuration (customising), development activities in the SAP system are often required to implement the project.

The processes you need

The experts at kallman support you in professionally designing adjustments to VAT processes and implementing them with technical precision. Our team of developers specialises in the implementation of solutions in a VAT context and has many years of experience in this field.

• Customised integration of third-party solutions
• Realisation of individual concepts
• Development of analysis reports (based on ABAP or CDS views)

Understanding and utilising data

In an increasingly data-driven world, the information in your SAP system is invaluable. On the one hand, the data in your SAP system provides valuable information that enables you to gain insights into VAT-related issues, and on the other hand, correct data forms the basis for the VAT-compliant execution of all transactions.

We bring light into the darkness

The kallman team supports you in making this crucial information visible, analysing it and using it optimally for your tax processes. We help you with the following tasks, among others

• Identifying business processes based on the data situation (deriving a transaction matrix)
• Performing plausibility checks and compliance checks (e.g. with the help of SAP Tax Compliance or SAP Risk and Assurance Management)
• Validation of VAT reports

With kallman, you create a solid foundation for your tax and compliance management and realise the full potential of the data in your SAP system.

From theory to SAP practice: Increasing efficiency, minimizing risks

The requirements for tax departments are rising while resources often remain scarce. Artificial intelligence (AI) is not an end in itself here, but a powerful tool to raise your compliance processes to a new level. The kallman team will show you how to integrate AI technologies into your VAT processes in a secure and value-adding manner.

Strategic goals of AI usage

• Preventive risk minimization: We consistently shift tax control to the beginning of the value chain. Through AI-supported validation, we identify potential compliance conflicts at the very moment the data is created – long before they become relevant for reporting or burden the system.
• Efficiency increase: We automate complex decision-making processes and routine tasks. In this way, we relieve the scarce resources in your tax department and create space for processing highly complex individual cases and providing strategic advice to the business.

Practical application areas across the entire tax cycle

We support you in the implementation of AI solutions in all relevant phases:

• Transactional level: Intelligent support for tax determination in complex purchasing and sales processes.
• Reporting & filing: Automated plausibility checks of the VAT return and EC Sales List to accelerate closing processes.
• Intelligent monitoring: Use of AI-supported analyses directly in the ERP system to recognize patterns in mass data that would remain invisible manually.
• Change management & strategy: Automatic analysis of the tax consequences in the event of changes to your business model (for example, new supply chains or foreign registrations).
• Horizon scanning: Automated monitoring of legal changes worldwide, filtered according to the relevance for your specific company profile.

AI power directly in the ERP system and in projects

Use AI where your data is located:

• Master data optimization: AI-supported cleaning and preparation of master data (for example, materials, customers, and vendors).
• Intelligent mapping: Efficient derivation of tax indicators directly from material descriptions or unstructured texts.
• Migration turbo: Use of AI in S/4HANA migration projects for automated data validation and mapping support.

AI is not a replacement for tax expertise – it is the lever that makes your specialist knowledge scalable.
