A product built on real-world SAP consultant feedback.
Evidra is a technology company focused on compliance automation for European businesses. Readix is our flagship product — a pre-flight e-invoicing validator built for the SAP ecosystem, covering the four EU mandates that matter most: KSeF (Poland), XRechnung (Germany), ebInterface (Austria), and ZUGFeRD/QR-Bill (Switzerland).
We spoke extensively with SAP consultants working on e-invoicing go-lives across DACH and Poland. The same problem kept surfacing: IDoc-to-UBL mapping errors discovered only after the government portal rejected the invoice. By then, weeks of rework had already begun.
Marlies Schröder, an SAP S/4HANA SD consultant in Germany, put it directly: "People who work on this issue are more than willing to pay to save time instead of working weeks on mappings back and forth with the customer."
That validated the core problem. We built Readix to fix it — a structured compliance check that runs before the government portal, not after.
Upload an invoice XML or PDF. Readix runs field-by-field compliance checks against the applicable EU e-invoicing standard and returns a readiness report within 24 hours — covering mandatory fields, VAT structure, format compliance, and business rule checks. The report tells you exactly what will cause a rejection and how to fix it, before the government portal sees it.
