Pioneer for e-billing and data exchange
Quality assurance, validation and implementation consulting since 2015
A careful GAP analysis identifies the key issues that need to be addressed for successful e-billing implementation.
Each data exchange requires a process description. The design, documentation and mapping definition are essential prerequisites for a smooth implementation.
Mistakes happen during implementation. Comparison of the implemented solution with the conceptual design and testing of the implementation lead to reliable operation.
I support organizations
20+ years experience
I founded validool.org part-time in 2015 to prove that even the smallest SMEs can successfully implement e-billing. Thus, the need for quality control with the XML.Valitool quickly arose.
As co-author of EN16931, technical inventor of the ZUGFeRD format and my many years of experience and leadership of national and international committees, I have extensive experience in data exchange
With my experience with EANCOM®, CashEDI, UBL, Cross Industry Invoice, XInvoice, OpenAPI and many other standards I am happy to support projects.
Solution providers who carry out the technical implementation of e-billing between in-house systems (ERP) and external communication appreciate my support through lectures, documentation and project-accompanying quality assurance. Examples of my work include mapping specifications, validation rules, schematron rules, and implementation testing for correctness.
