Sovereignty: 1 of 4 dimensions proven

The written short answer is being updated after a re-evaluation. The scores below are current.

Read this comparison as one judge. Each weighs the same scores by what they care about.

The Works Council Advocate

Sits on the Betriebsrat and has to approve this rollout under BetrVG §87. Reads every feature for whether it can monitor behaviour, and asks what is logged, who can read it and what can be switched off. A tool that cannot answer those questions does not get installed, however good it is.

HRworks

rexx systems

This judge's pick

Criterion by criterion

Digital personnel file & data model

HRworks

A digital personnel file holding "sämtliche Personaldaten und Dokumente" with configurable roles and need-to-know access is confirmed, and pay-transparency requirements are said to be implemented in software. But the evidence evidences no org chart, no custom fields and no dated history of contract or compensation changes, so it sits between the flat-structure and full-file anchors.

rexx systems

The digital personnel file page shows a genuinely structured file: salary data and development, complete historization with revision-safe archiving, batch scanning, document generation and digital signature, plus organisation management covering subsidiaries and multi-entity administration. We found no public information on effective-dated contract history or field-level permissions, so I cannot call it the auditor-grade single source of truth.

Payroll handoff

HRworks

DATEV "Corporate und Schnittstellen Partner" status plus ADDISON as a named partner, with a Payroll module in the base suite, is a vendor-maintained named integration beyond a generic export. The evidence is silent on variable pay, absences, mid-month joiners/leavers and any pre-payroll check, so it cannot reach the certified-integration anchor.

rexx systems

An official DATEV interface partnership covering LODAS and Lohn und Gehalt, with change-based master-data transfer, variable pay, absences, payslips flowing back, and named connections to ADP, Paisy and SAP HR — that is a vendor-maintained, certified-grade handoff. We found no public information on a documented pre-payroll check, an approval and lock step, or retro-accounting, which is why I stop short of a fully governed payroll process.

Absence & working-time

HRworks

Working-time capture via smartphone or stationary system, transparency over breaks, overtime and minus hours, monthly overviews, vacation and sick leave, and an explicit "automatisch EuGH- und DSGVO-konform dokumentiert" claim meet the recording duty at a basic level. But "Kontrolle der Soll- und Ist-Stunden" by Vorgesetzte is a monitoring capability with no evidence of configurable monitoring limits, tamper-evident records, holiday calendars or a labour-inspection export — the §87 questions go unanswered.

rexx systems

Working-time capture via browser, app and terminal, multiple time accounts, overtime caps, shift models and automatic implementation of legal requirements across countries, joined by pro-rata entitlement, eAU sick certificates and full absence history online. As the councillor signing off the recording duty, I have to note we found no public information on tamper-evident time records, documented ArbZG compliance, or monitoring limits a works council could configure — and sickness statistics sit in the reporting engine with no stated off-switch.

Recruiting & onboarding

HRworks

"Bewerbermanagement von A bis Z", a jobs portal in corporate design, AI job-ad drafts and onboarding document collection are confirmed. The evidence gives no evidence of structured stages, rejection handling, GDPR applicant retention and deletion, or a candidate-to-employee handover without re-entry, so it stays below the anchor-5 flow.

rexx systems

The join path is real: multiposting with named channels such as finest-jobs.com and the Bundesagentur, CV parser, scorecards, calendar synchronisation and e-signed contracts flowing seamlessly into onboarding workflows with equipment provisioning, timelines and automatic reminders. Two AI details read well for co-determination — humans make the final decision and CV parsing is the applicant's opt-in — though we found no public information on approval-gated requisitions or automated applicant deletion in the product itself.

Employee data protection & co-determination

HRworks

A Bitkom Consult audit confirming GDPR compliance, ISO 27001, DPA and TOM on request, need-to-know roles, logged inputs and logins, and a privacy mode for service requests are more than a procurement checklist. But no retention periods are stated, deletion is never shown as executable, the audit log records inputs and logins rather than who read what, and nothing documents that Personalcontrolling analytics can be switched off — I could not pass this through a works council vote on these pages alone.

rexx systems

Encryption, role rights and an audit trail are claimed, the operation is ISO 27001:2022 certified, and data-subject rights are documented — but the public pages do not answer my three questions: what exactly is logged, who can read it, and what can be switched off. We found no public information on a signable data-processing agreement, employee retention periods per data category, or configurable limits on behavioural features such as sickness-statistics reporting and the monitoring of onboarding-talk documentation.

European sovereignty

HRworks

HRworks GmbH in Freiburg (HRB 5406) with German Sitz und Gerichtsstand, EU server location as standard and AWS named as the hosting provider is a solid EU answer. The subprocessor list is entirely absent — the buyer knows the data centre but not the chain behind it.

rexx systems

A Hamburg-based GmbH running its own cloud on German and Swiss ISO-certified data centres, with an on-premises option for buyers who need it — that is the reassurance a council wants on paper. We found no public information on the product's subprocessor list or the data-centre provider's name, and the imprint lists group entities in Austria and Switzerland without saying which one signs customer contracts.

Pricing transparency

HRworks

The pricing page shows no numbers at all — "Erhalten Sie Ihr passendes Angebot" — with an HR WORKS Pro tier described but unpriced. A claim of "transparente Preise ohne Mindestlaufzeiten" and a free trial exist, but no per-employee price is public, so an HR lead cannot compute any part of the invoice from these pages.

rexx systems

The pricing page states the software is calculated individually with no standard packages, and the only concrete figures anywhere are consulting and training hours in an entry package, with no prices. An HR lead cannot compute an annual invoice for their headcount from the public pages; every number is a sales conversation.
