Why teams connect Epicor ERP and Greenhouse

Sync the workers, org structure, and cost centers that Epicor ERP and Greenhouse share in real time, so the people Greenhouse manages stay current in the system that runs finance and operations.

Greenhouse is the system of record for people: who was hired, which department and location they sit in, who they report to, and how they are paid. Epicor ERP runs finance and operations, and much of what it does depends on that same information, from booking labor cost to approving an expense report to staffing a project. Where the two are bridged by re-keying or an overnight file, each side spends the day out of step, with new hires missing from the systems they need and leavers still active where they should not be.

Stacksync syncs Suppliers, Parts, Sales orders, Purchase orders in Epicor ERP with Departments and Offices, Candidates, Applications, Jobs in Greenhouse field by field, in real time, and in both directions. You decide which system owns which fields, so the people side stays authoritative for worker data while Epicor ERP keeps its own accounting and operational detail, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 Sync Epicor customers and AR invoices into a CRM so sales sees order history and credit status without ERP logins.
  • 02 Push won opportunities from the CRM into Epicor as sales orders and sync order status back.
  • 03 Export Scorecards and Scheduled Interviews to a data warehouse to analyze interviewer load and interview outcomes.
  • 04 Two-way sync Candidates and Applications with Postgres so recruiting-ops apps read and update stage, status, and custom fields in SQL while recruiters stay in Greenhouse.

Common sync patterns

Reporting lines drive approvals

Manager and reporting-hierarchy changes in Greenhouse keep expense and purchase approval chains in Epicor ERP pointed at the right people.

Where Greenhouse runs payroll: labor cost in the books

Pay and compensation data from Greenhouse posts into Epicor ERP as labor cost, so finance sees workforce spend without re-entering it by hand.

Where Greenhouse is the worker system of record: one employee master

When a worker is hired, moved, or offboarded in Greenhouse, the matching employee record in Epicor ERP is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

What you can sync between Epicor ERP and Greenhouse

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Epicor ERP objects Greenhouse objects How this pairing syncs

Jobs Requisitions with openings, hiring team, departments, and offices; created and patched via Harvest, read out for funnel and time-to-fill reporting. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Quotes Estimates that pair with CRM opportunities during the sales cycle. Scorecards Interviewer feedback and ratings tied to interviews; read-only in Harvest, exported to a warehouse for interview analytics. Quotes is specific to Epicor ERP and Scorecards to Greenhouse — each maps to any object or custom field on the other side.

How changes propagate between Epicor ERP and Greenhouse

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Epicor ERP Greenhouse Interval-based propagation

DetectionStacksync polls Epicor ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change-date fields.

DeliveryEach detected change is written to Greenhouse through its API, with automatic retries and rate-limit backoff.

Greenhouse Epicor ERP Sub-second propagation

DetectionGreenhouse notifies Stacksync of record changes through webhook events. HMAC-SHA256 signed webhooks for candidate, application, job, and interview events, plus polling list endpoints with created_after / updated_after /.

DeliveryEach detected change is written to Epicor ERP through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Epicor ERP: Subject to the platform's API rate limits and per-tenant throttling on Kinetic cloud deployments.
  • Greenhouse: Harvest enforces a per-integration limit over a rolling 10-second window (X-RateLimit-Limit, commonly 50 requests / 10s for approved integrations); responses carry X-RateLimit-Remaining and, on a 429, X-RateLimit-Reset and Retry-After.
