For the success of our clients, we connect 'Taxation, Technology', and Controls.

We are recognized as a leading boutique for 'Taxation and SAP' by our clients, employees, and business partners.

We develop and install turn-key SAP add-ons that enhance standard SAP to timely submit tax reporting, and that optimizes the SAP VAT determination logic.

Besides that, we offer bridging software and MacroExcel solutions for multinationals within Europe to submit tax reporting and prepare tax reporting with digital audit trails of any manual changes and VAT control functionality. That MacroExcel functionality - tested and operational at multinationals - is used for the design of our SAP add-ons to ensure these add-ons meet clients needs. 

Key Group and SAP

The Key Group (KG) is a tax consultancy firm specialized in SAP and Tax. The founder is a former EY Tax partner. KG operates from the Netherlands, and Slovakia. KG provides an end-to-end solution from development to implementation to maintenance support. 

KG is an official SAP partner and tax consultancy firm and SAP granted the namespace 'KGT'. 'KGT' stands for 'Key Group Tax'.

KG is an expert in building in SAP extra functionality that standard is not available. We enhance SAP via our SAP add-ons. SAP is aware of these weaknesses and granted access for additional functionality in user exists.

KG develops SAP add-ons for tax reporting and automated VAT determination for both incoming and outgoing invoice. Specific European governments in Europe have digitalized tax to perform efficient and effective tax audits. That means companies that run SAP have to be able to submit tax reporting almost real-time or on a periodical basis.

What is an SAP add-on?

An SAP add-on enhances standard SAP itself.

Add-on components are extra functionalities that do not come with the main SAP product. Different organizations have different requirements. SAP has recognized that and facilitated that additional functionality can be added and that such functionality as a component can be integrated with standard SAP.

An add-on is permitted by SAP – the code 'ABAP' is written and transported where SAP allows it. That means these add-on components sit above the core and access the same dictionary objects or repository objects and perform the required functionality. It contains custom authorization objects according to SAP standards.

SAP add-on solutions are, therefore, without an external interface or external software and can be implemented with minor or no SAP impact in any other area. An SAP add-on does not change the programming code of SAP. As a result, SAP upgrades do not lead to any problems, and maintenance is straightforward.

Additional functionality is added to standard SAP:

'User-friendly, manageable, scalable, extendable, upgradeable, reliable, sustainable, SAP integrated, VAT compliant, audit trail'

User and implementation documentation

At moment a SoW is signed the KG team will provide to client user and implementation documentation where users are explained step by step how to execute a certain action supported by screen shots.

When a new transport is provided, KG will explain the changes in an e-mail, but as well update documentation. Our documentation contains dates of review and additional sign off in case of any important changes.

The documentation is written in professional business English and signed off from a quality control perspective by both Tax and SAP technical experts.

Our R&D and test environment

The methods used implemented by European countries substantially differentiate, so every country rollout has to be developed from scratch, taking into consideration first the local tax requirements. Portugal, Poland, Lithuania, Hungary, Italy, Spain, and the UK have implemented these new tax reporting requirements.

R&D is done by tax experts with involvement of native speaking tax consultants to meet the local tax requirements. Our test environment in SAP contains sufficient data, and reflects transactions of a standard multinational.

Proper testing before roll out and the quality controls executed limits the number of transports needed to the solution operational. Tax SAP experts and ABAP developers working together satisfying your needs.

Mapping and configuration will be done by Tax SAP experts supported by developers.

From an R&D and Quality Control perspective we work together with Global VAT Compliance (GVC) and INSynQ.

Formal support and active involvement of senior management

Optimum process improvement or business transformations will not likely be realized by the sum of individual independent efforts.The risk is that individually everybody knows what needs to be done within his or her own area of expertise, but what is lacking is overall direction and thus progress.

Anticipate what users would want

We combine technical knowledge with industry understanding and knowhow of technologically advanced tools and methodologies available in the market or developed by ourselves.

What do we like to achieve

  • Focus on tax processes that could be improved
    • Manual process: same data requests are made by different stakeholders
  • As Is assessment
  • Anticipate future changes and the data needed
    • What are tax trends?
    • What is happening locally and what should be considered across jurisdictions where you operate?
    • Anticipate new stakeholders and their data needs or requests (internal and external)
  • Define scope and actions for short, mid and long term
  • Write business case for change
  • Realize sponsorship for implementation

‘As is’ assessment, actions and business case

  • What tax data is requested and by whom?
  • What tax process can be improved and what can be automated?
    • CIT, VAT, tax data warehouse
  • What is the Return on Investment?
    • Hard saving: process improvement
    • Meeting (new) tax requirement
  • What systems are in use: SAP, Oracle, etc
    • By which entities?
  • How many end-use computing tools (e.g. excel spreadsheet) do we have?
  • How do we avoid an ad-hoc solution?
    • Understand the bigger picture
    • Real problem and not the symptom

Risk and reward

Technology-related tax risk: understand and address the potential harms and benefits of (new) technology.

Technology tools & systems integration

Ascertaining proper IT support for ensuring efficient, timely and reliable reporting.

Change and project management

VAT should be considered in every aspect of the process, from concept through completion and beyond. Managing by design — looking at any process or transaction from end to end and factoring in all the requirements and controls essential to designing and optimizing a compliant VAT process.

Effective communication and teaming

We speak the language of the business and IT and no translation is needed.
