Your Tools. Our Expertise. Zero Friction.
Connect Polyarx to the HR and accounting tools you already use. Employee data flows automatically, so you can focus on building your DACH team.
Disconnected tools. Double data entry. Endless errors.
Manual Data Entry
Without integrations, every new hire means keying the same data into your HRIS, payroll, and EOR platform. It's slow, tedious, and error-prone.
Data Discrepancies
When systems don't talk, information drifts. Salary updates in one system don't reach another. Compliance gaps appear.
Delayed Payroll
Manual processes create bottlenecks. Late updates mean late payroll runs and frustrated employees.
Your tech stack should work together, not create more work.

Why integrated EOR matters
Eliminate Manual Entry
Stop keying the same employee data into multiple systems. Information flows automatically from your source of truth to Polyarx and back.
Ensure Payroll Accuracy
When salary changes, promotions, or bonuses happen in your HRIS, they automatically update in payroll. No missed updates, no underpayments.
Single Source of Truth
Choose your canonical system. Polyarx syncs bi-directionally so your data stays consistent across platforms.
Faster Onboarding
New hire data from your ATS flows directly into EOR onboarding. Employees start day one without paperwork delays.
Built for DACH. Not adapted for it.
While global EOR providers offer generic integrations, we support the tools German-speaking companies actually use.
Personio is the leading HR platform in Germany. We integrate natively, supporting German-specific fields, contract types, and compliance requirements that global providers miss.
DATEV is the standard for German tax advisors. Our DATEV-format exports mean your Steuerberater receives data exactly as they need it. No reformatting, no errors.
German payroll (Lohnabrechnung) has unique requirements: social security, church tax, Minijobs, works councils. Our integrations handle them all.
Frequently asked questions
Everything you need to know about our integrations.
We integrate with leading HRIS platforms (BambooHR, Workday, HiBob, Personio), accounting systems (QuickBooks, Xero, DATEV, Sage), ATS platforms (Greenhouse, Lever, Ashby), and productivity tools (Slack, Microsoft Teams). We're constantly adding new integrations based on customer needs.
Most integrations can be configured in under 15 minutes. You'll authorize access through secure OAuth, select your sync preferences, and data starts flowing immediately. No IT projects required.
Absolutely. All integrations use OAuth 2.0 or encrypted API keys. Data is encrypted in transit (TLS 1.3) and at rest (AES-256). We're GDPR compliant and host all EU customer data in European data centers. We never store credentials in plain text.
We're always expanding our integration library. Contact us with your requirements and we'll prioritize based on customer demand. For enterprise customers, we offer custom integration development.
Syncs happen in near real-time for critical data like new hires and terminations. Standard data like org changes and compensation updates sync on a configurable schedule (hourly, daily, or on-demand). You control the direction: one-way or bi-directional.
In most cases, no. HR and Finance leaders can set up integrations directly. For enterprise SSO or custom configurations, we provide documentation for IT teams and can join setup calls if needed.
We monitor all syncs proactively. If a sync fails, you'll receive an alert with the specific issue and remediation steps. Our support team can help troubleshoot. Failed records are queued and retried automatically.
Yes. Integrations scale with your team. Whether you have 1 EOR employee or 100, the same integrations apply. Pricing is per-employee, not per-integration.
