# Connect Greenhouse to Gusto > Stop copying candidate data between your ATS and HR platform. Sync new hires, employee records, and onboarding tasks automatically. **Canonical page:** https://tray.ai/connectors/greenhouse-gusto-integrations/ **Greenhouse connector:** https://tray.ai/connectors/greenhouse-integrations/ **Greenhouse documentation:** https://tray.ai/documentation/connectors/service/greenhouse **Gusto connector:** https://tray.ai/connectors/gusto-integrations/ **Gusto documentation:** https://tray.ai/documentation/connectors/service/gusto ## Overview Greenhouse and Gusto handle two separate parts of the employee lifecycle — recruiting and HR/payroll — but most teams bridge them with copy-paste. Integrating Greenhouse with Gusto means every accepted offer automatically triggers the right onboarding steps in Gusto, cutting time-to-productivity and removing the data entry errors that come with manual handoffs. From the moment a candidate applies to their first paycheck, the two platforms work together without anyone in the middle. When your recruiting team closes a hire in Greenhouse, your HR and payroll team in Gusto shouldn't be the last to know. Without an integration, HR coordinators manually transfer candidate names, job titles, start dates, compensation details, and department assignments from Greenhouse into Gusto — a tedious process that introduces transcription errors, causes payroll delays, and creates compliance risks. Connecting Greenhouse and Gusto through tray.ai automates this handoff. The moment a candidate is marked as hired, Gusto is updated with accurate employee records and onboarding workflows start without delay. People Ops teams can scale hiring without adding HR admin headcount, and new employees get a consistent, professional onboarding experience from day one. ## Use cases ### Automated New Hire Record Creation in Gusto When a candidate is marked as hired in Greenhouse, tray.ai automatically creates a new employee record in Gusto populated with offer details including name, job title, department, start date, and compensation. No manual re-entry of data that already exists in Greenhouse, and Gusto records are accurate from the start. - Triggers Gusto setup within minutes of an offer acceptance - Eliminates transcription errors between ATS and payroll systems - Gets payroll configured correctly before the employee's first day ### Offer Letter Compensation Sync to Payroll Compensation data captured in Greenhouse offer letters — salary, pay frequency, bonus structures — is automatically mapped and pushed into the corresponding Gusto employee profile. Compensation details stay consistent across both platforms without HR reconciling records manually. - Sources compensation directly from signed offer data, so payroll figures are accurate - Removes the risk of outdated or mismatched salary information in Gusto - Saves HR teams hours of reconciliation work each hiring cycle ### New Hire Onboarding Task Kickoff Once a candidate is hired in Greenhouse, tray.ai triggers a predefined onboarding checklist in Gusto — document collection, benefits enrollment, tax form submission. Every new employee gets the same onboarding experience regardless of which recruiter closed the hire. - Standardizes onboarding across all departments and locations - Reduces time HR spends manually starting onboarding sequences - New hires get prompt, professional onboarding communication from the start ### Department and Cost Center Alignment Greenhouse stores detailed job and department information that needs to be reflected accurately in Gusto for reporting and payroll purposes. The integration mirrors department codes, cost centers, and team assignments from Greenhouse into the Gusto employee record automatically. - Keeps payroll reporting aligned with organizational structure in real time - Reduces errors in department-level budget reporting - Eliminates discrepancies when HR and Finance run workforce cost analyses ### Rehire Detection and Record Reactivation When a previously employed candidate is rehired through Greenhouse, tray.ai checks for a matching record in Gusto and triggers a reactivation workflow instead of creating a duplicate employee profile. Your HR database stays clean and payroll complications don't follow. - Prevents duplicate employee records from polluting Gusto payroll data - Automatically flags rehires for HR coordinators to review - Reduces compliance risk from duplicate tax filings ### Candidate Data Sync for Background Check Coordination After an offer is extended in Greenhouse, candidate details are automatically forwarded to Gusto to begin pre-employment verification or meet state-specific onboarding compliance requirements. HR has everything it needs in both systems before the employee's official start date. - Speeds up pre-employment processing by removing manual data handoffs - Gets compliance documentation started before day one - Gives HR one source of truth across recruiting and people management tools ### Headcount and Workforce Analytics Consolidation Keeping Greenhouse hiring pipeline data in sync with Gusto employee records lets People Ops and Finance build accurate headcount reports that reflect both in-progress offers and confirmed hires. Leadership gets real-time visibility into workforce growth without manual spreadsheet reconciliation. - Real-time headcount dashboards that span ATS and HR data - Less reporting lag when systems update automatically - Better workforce planning with accurate, current data ## Templates ### Greenhouse Hired Candidate → Create Gusto Employee Automatically creates a new employee record in Gusto the moment a candidate's stage is updated to Hired in Greenhouse, transferring all relevant personal, compensation, and job details.

Greenhouse organizes data around candidates, applications, and offers; Gusto organizes it around employees, compensation, and payroll schedules. Mapping fields between these two schemas takes time and it's easy to get wrong, especially when custom fields or variable compensation structures are involved. **How Tray.ai helps:** tray.ai's visual data mapper and flexible transformation logic let teams build precise, reusable field mappings between Greenhouse and Gusto. Custom fields, conditional logic for pay types, and department code lookups are all handled inside the workflow — no custom code needed. ### Handling Offers in Multiple States or Currencies Companies hiring across multiple states or internationally deal with different tax jurisdictions, pay schedules, and employment classifications that need to be accurately reflected in Gusto at the point of hire. Greenhouse may capture this at the offer level, but translating it cleanly into Gusto requires careful logic. **How Tray.ai helps:** tray.ai supports conditional branching within workflows, so different onboarding paths, pay configurations, or Gusto entity targets are applied based on the new hire's location or employment type as captured in Greenhouse. You don't need separate integrations for each scenario. ### Avoiding Duplicate Employee Records If a candidate applies multiple times, or if the integration fires more than once for the same hire event, Gusto can end up with duplicate employee records that cause payroll and compliance problems. There's no native deduplication logic between the two platforms. **How Tray.ai helps:** tray.ai workflows query Gusto for an existing employee by email before creating a new record. If a match is found, conditional logic stops record creation and routes a review alert to HR — catching duplicates before they happen. ### Keeping Systems in Sync When Offer Details Change Offer details — salary, start date, job title — get revised after an initial offer goes out in Greenhouse more often than you'd expect. Without an active sync, those changes don't reach Gusto, which means incorrect payroll setup or onboarding documentation. **How Tray.ai helps:** tray.ai monitors Greenhouse for offer update events and triggers downstream updates to the corresponding Gusto employee record whenever those fields change. Gusto always reflects the current, approved offer terms — not the original draft. ### Managing Integration Errors Without Losing Hire Data API rate limits, temporary outages, or data validation failures in either Greenhouse or Gusto can cause hire events to fail silently. New employees may not be set up in payroll before their start date — a real operational and compliance problem. **How Tray.ai helps:** tray.ai has built-in error handling, retry logic, and alerting that catch failures in real time. If a Gusto record creation fails due to a validation error or API issue, the workflow logs the failure, retries automatically, and notifies the HR team so no hire event slips through. ## Learn more - Intelligent Integration: https://tray.ai/platform/intelligent-ipaas/ - Merlin Agent Builder: https://tray.ai/platform/merlin-agent-builder/ - Agent Gateway for MCP: https://tray.ai/platform/agent-gateway/ - Book a demo: https://tray.ai/contact/
