About me

Marcel Sedas Ladwig

Accounting & Finance Systems Specialist


Finance and accounting have been a constant companion since my apprenticeship as an industrial clerk and have formed the common thread of my professional life ever since.


During my career, I have gained extensive practical experience in accounts receivable, accounts payable, banking, fixed asset and general ledger accounting, as well as in account reconciliations, month-end and year-end closing, and financial analysis. I have worked in both medium-sized companies and internationally oriented corporate environments.


With increasing experience, it became clear to me that many accounting difficulties do not stem from a lack of expertise. Often, the causes lie in unsuitable processes, separate data sources, unclear responsibilities, or repetitive manual work.


Therefore, I have specifically expanded my accounting experience to include ERP systems, data migration, system integration, Excel/VBA automation and management reporting.


Today I combine professional accounting with technical implementation and develop solutions that are arithmetically correct,

are transparently structured and actually usable in daily workflows.


I'm not a typical software developer who looks at accounting processes from the outside. I come from an accounting background myself and develop the tools that I felt were missing in my daily work.

Areas of expertise

Accounting & Finance

My work is based on sound experience in financial accounting, month-end closing and the reconciliation of complex issues.



My focus is on verifiable results, reliable controls, and an understanding of the complete context behind the numbers.

ERP & System Integration

I work with financial data from Microsoft Dynamics 365 Business Central, SAP and other business upstream systems.


My focus is on data migration, system alignment, process design, and the controlled connection of different data sources.

Automation & Reporting

Using custom-developed Excel/VBA applications, I transform recurring manual tasks into structured and reproducible processes.


This results in practical solutions for accounting, controlling, reporting, data verification and management information.

working method

For me, an application isn't finished simply because it works technically. It must also be technically sound, reliably verifiable, and understandable for its users.


Therefore, I always consider the entire process: from the data source through processing and validation to the finished result.
