EN 16931 explained

EN 16931 is the European standard framework behind many structured invoice workflows. In practical terms, it matters because invoice files are expected to carry consistent business fields that software can process across systems.

Why users should care

You do not need to memorize the standard to benefit from it. You only need to know that many invoice validation and exchange processes expect structured fields to exist in a predictable way.

Where Tooltensor fits

Tooltensor does not certify formal EN 16931 compliance. It helps users inspect invoice files and see whether the most important fields are even present before a deeper validation process begins.
