ZUGFeRD / Factur-X / XRechnung PDFs and raw CII, UBL or ebInterface XML are read directly. Text PDFs go through the layout heuristics.

        A
        Fast path
        Hybrid PDFs carry their data as embedded XML. The engine reads the attachment tree, parses CII, UBL or ebInterface and skips OCR entirely. Typical latency is under ten milliseconds.
        
    
        ↗
        B
        Extraction
        Plain PDFs are rebuilt from their text layer with column aware line reconstruction and DACH label heuristics. Scans go to an optional vision model on your own GPU, never to a third party by default.
        
    
        ↗
        C
        Validation
        Line math, VAT breakdown and totals are recomputed. UID and USt-IdNr check digits, IBAN mod 97 and the EN 16931 business rules run on every document, with XRechnung and ebInterface profiles on top.

        SafeCloud AI for scansScanned and photographed invoices are read by Qwen vision models on a dedicated GPU server in Germany (Hetzner). Images are sent, processed and dropped. Nothing is trained on your data.
        
      
        EU infrastructure end to endAPI, OCR and your optional dedicated instance all run in the EU under one operator. One data processing agreement covers the whole chain.
        
      
        Open weights, no lock-inThe models are open-weight and the engine is a Docker image. Sovereign customers can run the exact same setup on-prem.
