The valitool® approach
A structured path to a valid result
We support you from the initial gap analysis to smooth live operation — with a structured,
transparent and practical approach.
Implementation supportSolution design
Every data exchange requires a process description. Solution design, documentation and mapping definitions are essential prerequisites for smooth implementation.
Quality assuranceValid result
Errors occur during implementation. Comparing the implemented solution with its design and checking the implementation provides a foundation for reliable operation.
Andreas Pelekies
More than 20 years of e-invoicing implementation experience
Andreas Pelekies founded valitool.org in 2015 to demonstrate that even the smallest businesses can successfully implement e-invoicing. This soon created a need for professional quality control — and led to today’s valitool®.
As co-author of EN 16931, technical inventor of the ZUGFeRD format and long-standing chair of national and international committees, he has extensive expertise in electronic data exchange.
With broad experience in standards such as EANCOM®, CashEDI, UBL, Cross Industry Invoice, XRechnung and OpenAPI, he supports businesses as a strategic partner.
Solution providers responsible for implementing e-invoicing between in-house ERP systems and external communications value his support through presentations, detailed documentation and project quality assurance. His core skills include developing mapping specifications, validation and Schematron rules, and rigorously checking implementation correctness.
