Cupel gives you the methodology of a licensed audit firm as a self-service tool. You review sustainability reports yourself, document every step, and export to your working papers. The justReporting audit firm stands ready when you need expert hours.
From first draft to assurance-ready version, without waiting for external reviewers.
Upload the sustainability report as PDF or Word. Cupel reads it paragraph by paragraph, preserving structure and formatting.
Cupel comments across three dimensions: Clarification, Evidence, and Correction. Directly on the text, traceable like an auditor. You add your own comments and sharpen them with AI.
All open findings collected by status and category, exportable as PDF and Word. Ready for auditor handover or your own working paper documentation.
Cupel checks against ESRS requirements: completeness, methodological consistency, and coherence across the full report. You see what is still missing before the statutory auditor arrives.
The tool provides structure. Where an audit judgment is needed, the auditors of justReporting GmbH WPG are personally available.
“I built Cupel because as an auditor I experienced first-hand how much time a structured first pass takes. The tool handles the routine part. I step in when it gets difficult.”
Jannik Hassel
Certified public accountant, justReporting GmbH WPG
