GraphBit VAT Validation

From 2027, e-invoicing makes every transaction machine-readable in Germany, for companies and tax authorities alike. Substantive VAT review has always been a sampling exercise, because checking every transaction against the law by hand was never feasible. Against a regulator who can review everything, sampling no longer holds. InfinitiBit builds deterministic AI for exactly this problem. GraphBit VAT Validation substantively reviews every transaction against the law in force on its date: expert-validated legal knowledge provides the rules, document analysis establishes the facts, and a deterministic core returns a reasoned, traceable verdict for each case, escalating anything ambiguous to a human expert. The same architecture powers customs validation, transfer pricing documentation, and audit-ready document assembly. The technology is peer-reviewed (EMNLP 2026), patent pending, and in production at one of the ten largest German audit firms, whose tax experts sign off on the results.
