TL;DR
The Collage–Greenhouse integration automates the transfer of hired candidates from Greenhouse into Collage so teams can begin onboarding, benefits enrollment, and payroll setup without manual data entry. This guide covers core features, who benefits, implementation checklists, data-mapping priorities, security considerations, KPIs to track, and common troubleshooting tips. When paired with upstream efficiency—such as AI resume screening via ZYTHR—the combined workflow reduces administrative hours, cuts errors, and accelerates time-to-productivity for new hires.
The Collage–Greenhouse integration moves new hires automatically from Greenhouse into Collage so HR teams can complete onboarding, benefits enrollment, payroll setup, and record-keeping without manual data entry. That sync removes hired candidates from Greenhouse candidate lists, creates employee records in Collage, and lets you begin onboarding workflows immediately. This page explains what the integration does, who should consider it, how to implement it, and the measurable benefits you can expect. Practical guidance covers required fields, common pitfalls, KPIs to track, and technical steps so your team can plan a low-risk rollout.
Core features of the Collage–Greenhouse integration
- Automatic hire sync Candidates marked as hired in Greenhouse are automatically created as employee records in Collage, removing manual entry and reducing transcription errors.
- Direct onboarding initiation Once a hire lands in Collage, onboarding workflows (forms, documents, benefits enrollment) can start immediately, shortening time-to-productivity.
- Candidate cleanup in Greenhouse Hired candidates are removed from your active candidate lists in Greenhouse, helping recruiters keep boards accurate and focused.
- Bi-directional updates (where configured) When enabled, changes in core employee fields propagate between systems so information stays consistent across HR and ATS tools.
- Payroll and benefits handoff Collage syncs with payroll providers and benefits carriers; onboarding data from Greenhouse feeds those downstream processes, reducing duplicate work.
Who needs this integration: companies that use Greenhouse for hiring and want to replace spreadsheet-based HR administration with an HRIS. Collage targets small- to mid-sized businesses (1–1,000 employees) and supports North American payroll and benefits workflows in English and French. Primary user groups that benefit: talent acquisition teams who want cleaner pipelines, HR generalists who manage onboarding and benefits, payroll admins who need accurate new-hire data, and hiring managers who want faster new-hire ramp-up.

Manual process vs. integrated workflow
| Manual (no integration) | Integrated (Greenhouse → Collage) |
|---|---|
| Recruiter marks candidate as hired in Greenhouse; HR copies candidate details into Collage spreadsheets. | Recruiter marks candidate as hired in Greenhouse; integration creates employee record in Collage automatically. |
| HR manually emails onboarding links, collects signed forms, and re-enters benefits selections. | Collage sends onboarding packets and captures e-signatures; benefits enrollment is recorded in HRIS. |
| Candidate stays in Greenhouse lists unless manually archived, cluttering pipeline views. | Hired candidate is removed from active Greenhouse lists, keeping ATS clean. |
| Payroll setup is often delayed and error-prone because of transcription mistakes. | Payroll-ready data flows from Collage into payroll providers, reducing setup time and errors. |
| Audit trail is distributed across email, spreadsheets, and ATS comments. | Audit logs and document storage are centralized in Collage for compliance and reporting. |
Implementation checklist (recommended sequence)
- Confirm prerequisites Verify Collage and Greenhouse admin access, identify the team owner, and confirm supported regions and plan levels.
- Review required fields Map required employee fields (name, email, start date, job title, employment type, payroll details) so no sync failures occur.
- Set up authentication Install the Collage app from Greenhouse or configure API keys/OAuth as documented in the Collage support resources.
- Configure field mapping and rules Decide how to handle department codes, employee IDs, timezones, and default values for missing fields.
- Run a sandbox test Test with a small set of hires in a staging environment or within a controlled timeframe to validate data flow.
- Enable auto-sync and monitor Turn on the live sync once tests pass, monitor the first 10–20 hires for errors, and adjust mappings or permissions as needed.
- Train stakeholders Document the new workflow for recruiters, HR, and payroll; hold a short training session and share troubleshooting steps.
Data mapping: prioritize the fields that downstream systems require. Typical high-priority fields are: legal full name, preferred name, email, start date, job title, department, employment type (full-time/part-time/contract), compensation, manager, work location, and tax identifiers where applicable. Configure default values for optional fields to prevent blocked syncs and set validation rules for date formats and currency. Practical tip: keep a one-page field-mapping document that lists the Greenhouse field, Collage destination, validation rule, and a fallback value. This reduces guesswork during troubleshooting and accelerates audits.
Technical prerequisites and configuration notes
- Admin access You need Greenhouse and Collage admin or integration-level permissions to install and authorize the connector.
- API connectivity Ensure your network allows outbound API calls to Collage endpoints and that any firewall rules permit the integration.
- Standardized field formats Agree team-wide on date formats, naming conventions, and department codes before mapping to reduce transform logic.
- Timezone and locale settings Confirm timezone handling for start dates and employment eligibility dates to avoid off-by-one start-date errors.
Frequently asked questions
Q: Will the integration remove the candidate from Greenhouse automatically?
A: Yes — when configured as described in Collage’s integration settings, hired candidates are removed from active candidate lists in Greenhouse to keep the ATS clean. Check your Greenhouse board rules to confirm behavior.
Q: Can I control which hires sync to Collage?
A: Most setups let you define a trigger (for example, a specific job stage or an explicit hire action). Use the integration settings to scope which jobs or positions should auto-sync.
Q: What happens if a required field is missing?
A: Missing required fields typically block the sync and generate an error. Configure validation and fallback defaults during mapping, and test with sample hires to identify required fields.
Q: Does Collage support payroll handoffs?
A: Yes — Collage integrates with payroll providers and can pass new-hire info downstream. Verify which payroll providers are supported for your region and plan.
Q: Where can I find official documentation?
A: Refer to Collage privacy policy and Collage/Greenhouse support pages for up-to-date technical docs and data-handling descriptions.
KPIs to measure after integration
- Onboarding completion time Track average hours or days from hire to completed onboarding tasks before and after integration.
- Administrative hours saved Measure HR and recruiter time spent per hire on data entry and compare pre- and post-integration.
- Payroll setup errors Monitor the rate of payroll correction requests or errors caused by manual entry.
- Time-to-productivity Track how quickly new hires complete required forms and access systems — shorter times indicate fewer handoffs.
Security and compliance considerations: treat the integration as part of your HR data surface area. Confirm encryption in transit and at rest, role-based access controls in Collage, and audit logging for onboarding documents and personal data changes. If your organization handles sensitive tax or work-authorization data, verify retention and access policies against regional regulations and Collage’s privacy policy. Practical mitigation: limit API keys to least privilege, rotate credentials regularly, and use a dedicated service account for the integration so actions are traceable in audit logs.
Roles and responsibilities during rollout
| Role | Responsibility |
|---|---|
| HR Lead | Define onboarding fields, validate business rules, and own verification of employee data post-sync. |
| Recruiting Manager | Agree on trigger stages in Greenhouse, confirm which job types use the integration, and inform recruiters of new processes. |
| IT/Integrations | Configure API/OAuth settings, ensure network connectivity, and manage credentials and firewall rules. |
| Payroll Admin | Validate payroll field mapping, test pay cycle imports, and confirm payroll provider compatibility. |
| Project Sponsor | Approve timelines, resource allocation, and sign off after pilot validation. |
Common pitfalls and troubleshooting tips
- Duplicate records Sometimes a previously created placeholder record causes duplicates. Use unique employee IDs or email as the primary key and clean up legacy placeholders before go-live.
- Date and format mismatches Start-date or currency formatting errors are frequent. Standardize formats and validate them in a test run.
- Permission errors If the connector fails, check API scopes and service account privileges for both Greenhouse and Collage.
- Missing required fields Map and enforce required fields in Greenhouse job templates so hiring teams capture needed data before marking hires.
Estimated time savings and business impact: practical deployments report saving between 30 minutes and 2 hours of administrative work per hire, depending on how many manual handoffs you replace. Savings compound with volume — at 50 hires per year, that’s roughly 25–100 hours saved, plus fewer payroll corrections and faster benefits enrollment. Conclusion: the Collage–Greenhouse integration reduces repetitive data entry, lowers error rates, and accelerates onboarding. With proper mapping, testing, and stakeholder training, it delivers clear operational ROI and a cleaner recruiter experience.
How this ties into resume screening: eliminating downstream manual work is most effective when upstream candidate selection is efficient. Using an AI resume screening tool like ZYTHR before candidates reach Greenhouse reduces the number of low-fit candidates entering the pipeline and ensures the hires you do sync to Collage are higher-quality matches. That combination — automated screening plus integrated onboarding — shortens hiring cycles and amplifies administrative savings.
