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 Data Protection Officer

Answers for the most sensitive personal data the company holds, about people who cannot decline the processing. Wants retention that executes rather than promises, a published subprocessor list, and applicant data that deletes itself on the stated date. Treats an unpublished DPA as a finding.

This judge's pick

Criterion by criterion

Digital personnel file & data model

HRworks

A digital personnel file "enthält sämtliche Personaldaten und Dokumente" with configurable roles and need-to-know access exists, but nothing evidences effective-dated contract or salary history, org structure across entities, custom fields, or retention per document type. The record is marketed well; the audit trail beneath it is undocumented.

rexx systems

The digital personnel file is substantial: complete historization and revision-safe archiving, salary development and cost-centre data held in the record, personnel documents generated straight into the e-file, batch scanning of paper files, and organisational management that covers subsidiaries. What I could not find on the captured pages is field-level permission control, effective-dated contract and compensation versions, and retention rules per document type — the difference between a good file and one an auditor can defend.

Payroll handoff

HRworks

A named DATEV integration ("Corporate und Schnittstellen Partner") plus ADDISON and a Payroll module in the base package clears the named-integration bar, which is why this is not a 3. But the evidence documents nothing on variable pay, mid-month joiners and leavers, a pre-payroll check, or retro-accounting — rubric level 8 territory is entirely unevidenced.

rexx systems

This handoff is built as a partnership: official DATEV interface partner status covering Lohn und Gehalt and LODAS, bidirectional transfer of master data, variable pay and absences with change-based delta synchronisation, payslips and tax certificates returned monthly into employee self-service, and further named connections to ADP, Paisy and SAP HR. We found no public information on a documented pre-payroll check, retro-accounting for backdated changes, or an approval and lock step before transmission.

Absence & working-time

HRworks

Working-time capture on terminal and smartphone with breaks, overtime and minus-hour accounts, monthly overviews, automated reports, and vacation/sickness handling sits above rubric level 5, and there is a claimed "EuGH- und DSGVO-konform" documentation. But no public-holiday calendars per location, no rest-period rule configuration, no labour-inspection-ready export, and no tamper-evidence are evidenced — for a legal recording duty I need more than a compliance slogan.

rexx systems

Working-time capture is real and multi-channel — browser, app, terminals with QR code or NFC, multiple time accounts, shift and overtime models, pro-rata entitlement on mid-year joiners and leavers, electronic sick certificates imported and matched to absence bookings, and a complete online history of every booking. For the German recording duty the captured pages stop short of the specific answers I look for: we found no public information on public-holiday calendars per location, break and rest-period rules, or works-council-configurable monitoring limits.

Recruiting & onboarding

HRworks

Applicant management "von A bis Z", a branded jobs portal, and onboarding document collection cover both halves of the join path, with "Employee Life Cycle in einer Software" hinting at continuity. Structured stages, rejection handling and no-re-entry handover are asserted rather than evidenced, and there is not one word on applicant retention or automated deletion at a stated deadline — the first thing I look for in recruiting data.

rexx systems

The join path runs end to end: multiposting to named boards including finest-jobs.com and the Bundesagentur, scorecards plus video and WhatsApp channels, digitally signed contracts with automated rejections, and applicant data flowing into an onboarding module that assigns tasks, timelines and equipment without re-entry. The six-month applicant deletion deadline with consent-based extension appears in the vendor's own privacy policy for its own hiring; we found no public information on automated applicant deletion at a configurable deadline inside the product.

Employee data protection & co-determination

HRworks

The AVV and TOM must be requested ("anfordern") rather than published and signable — that is a finding in my book, and it caps this score. Roles are genuinely configurable with need-to-know access, ISO 27001 certification and a Bitkom GDPR audit back the security layer, but no retention period is stated, no deletion is shown to execute, the audit log records inputs and logins rather than who read what, and no subprocessor list appears anywhere.

rexx systems

Here I must record findings: we found no public information on a signable data processing agreement, no published subprocessor list for the product, and no evidence that employee-data retention or deletion executes on defined dates rather than ending as revision-safe archiving the customer administers. Encryption, role rights and an audit trail are named, operations are ISO 27001:2022-certified in German and Swiss data centres, and the privacy policy does state automatic deletion for website analytics — but for the most sensitive data about people who cannot decline the processing, that is thin.

European sovereignty

HRworks

The imprint evidences a German contracting entity (HRworks GmbH, HRB Freiburg 5406) with German seat and jurisdiction, EU server location, and a named data-centre provider in AWS — a real sovereign footing, whatever the pipeline's capture failed to confirm. What keeps this from rubric level 8 is the absence of a published subprocessor list and any naming of non-EU processing with its legal basis.

rexx systems

The foundations are European: a Hamburg contracting entity with a German register number, hosting in the vendor's own cloud on German and Swiss servers in ISO-certified data centres, and a genuine on-premises option. The chain is where it weakens — the data-centre provider behind the own cloud is not named, we found no public information on product subprocessors or on the vendor's ownership, and the imprint lists Austrian and Swiss sister entities without stating which of them signs customer contracts.

Pricing transparency

HRworks

Two captures of the pricing page show no numbers whatsoever — "Erhalten Sie Ihr passendes Angebot" — so every tier is a sales conversation. The slogan "Transparente Preise ohne Mindestlaufzeiten" is a claim, not a computable invoice; this is the anchor-0 case almost verbatim.

rexx systems

The pricing page states the software is calculated "individuell und nachvollziehbar" with no standard packages, and even the preconfigured entry package for smaller companies — 32 consulting hours and eight training hours — carries no figure. No per-employee price appears on the captured pages; an HR lead cannot compute one euro of the annual invoice from public information.
