What it does

Everything the German invoice process demands

Six capabilities that cover the full lifecycle — from a blank draft to a validated, archivable e-invoice.

Invoicing

Draft to finalized with legally serialized numbering per § 14 UStG, per-line VAT, customers and a unified item catalog.

AI Scan

Photograph a paper receipt. Edge detection, OCR and unit inference turn it into a compliant e-invoice.

E-Invoicing

ZUGFeRD, XRechnung 3.0 and EN 16931 — generate, convert, extract and validate with plain-language errors.

PDF Designer

Drag-and-drop layout editor with live data binding, undo/redo and a mandatory-field compliance check.

Access Control

43 permissions, custom roles and per-user overrides where deny always wins — enforced on API, menu and route alike.

Audit Trail

22 action types across 13 entity types, CSV export, and a history that survives user and company deletion.

AI Scan

From paper receipt to e-invoice

Photograph or upload an invoice. The receipt edge is detected automatically, layout and fields are read, units are inferred from a German keyword dictionary, and gross/net totals are reconciled against the printed total — then exported as ZUGFeRD or XRechnung.

  • Runs on our own servers — not a third-party cloud OCR
  • HEIC, JPG and PNG, converted in the browser
  • Live EN 16931 completeness check before export

E-Invoicing

Five profiles, one validator

Generate ZUGFeRD EN 16931, XRechnung 3.0, Extended or Basic — or convert an existing PDF. Upload an XRechnung XML or ZUGFeRD PDF and get a multi-layer report covering XSD schema, business rules, PDF/A-3 conformance and XML embedding.

  • Plain-language errors instead of raw validator output
  • Extract XML from existing ZUGFeRD / Factur-X PDFs
  • ERP export as JSON or 34-column CSV

PDF Designer

Design the document, bind the data

A full drag-and-drop layout editor: text, tables, totals, QR codes, barcodes, logos and signatures. Bind any invoice field with tokens that resolve live in preview — then let the built-in check confirm every legally mandatory field is present.

  • Undo/redo, layers, align, snap and rulers
  • Import and export template JSON
  • Checks against EN 16931 core or the stricter German CIUS

Access Control

A real ACL, not role labels

43 permission keys organised as a module → component → action tree. Create custom roles, then layer per-user grants and denials on top — deny always wins, for every role including the owner.

  • One key gates the API, the menu and the route
  • Modules you cannot reach never ship their JavaScript
  • Changes apply on the user's very next navigation
