KoSIT validation
EN 16931 conformance with per-tenant validator configuration — XRechnung updates without downtime.
iQuantum — Product
RechnungsRadar
The e-invoice compliance & accounts-payable agent for the German Mittelstand — from XRechnung intake to GoBD-compliant archive, with a human approving every posting.
01 — The problem
E-invoicing is mandatory in German B2B — and suddenly every company receives XRechnung XML and ZUGFeRD hybrids that must be validated, correctly posted and archived audit-proof for years. Doing that by hand is slow; doing it wrong is a Betriebsprüfung finding.
02 — How it works
(01)
Receive on every channel
E-mail inbox (M365/Google), Peppol network and direct upload — invoices are deduplicated and normalized on arrival.
(02)
Validate & classify
Formal validation against EN 16931 with the official KoSIT validator, then deterministic-first classification for ERP posting — AI only steps in where no matured supplier rule exists.
(03)
Approve, post, archive
A review inbox with inline correction keeps humans in control; approved invoices post to your ERP (DATEV, Lexware, SAP B1) and land in a GoBD-compliant WORM archive with a verifiable hash chain.
03 — Capabilities
ERP connectors
DATEV (Buchungsstapel + Belege), Lexware Office and SAP Business One out of the box.
GoBD audit export
GDPdU/Z3 export with index, WORM artifact bundle and verified hash chain — Prüfer-ready.
Value telemetry
Hours-saved and automation KPIs per tenant — the dashboard shows what the agent earns you.
04 — Compliance first

Which invoice formats does RechnungsRadar accept?
XRechnung (UBL and CII), ZUGFeRD hybrid PDFs, and plain PDFs — arriving via e-mail inbox (M365/Google), the Peppol network or direct upload, with deduplication on arrival.
Is the archiving really GoBD-conform?
Invoices land in a WORM store with a verifiable hash chain, a per-tenant Verfahrensdokumentation, and a GDPdU/Z3 audit export a Prüfer can consume directly.
Which ERP systems are connected?
DATEV (Buchungsstapel + Belege), Lexware Office and SAP Business One out of the box — others via the API.
Does AI post invoices automatically?
Classification is deterministic-first from matured supplier rules; AI only assists where no rule exists, and a human approves every posting in the review inbox before it reaches your ERP.
