Why teams connect Greenhouse and Rootstock ERP

Sync the workers, org structure, and cost centers that Rootstock 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. Rootstock 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 Items / Products, Bills of Material, Inventory Balances, Receipts and Shipments in Rootstock ERP with Candidates, Applications, Jobs, Offers 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 Rootstock 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 inventory availability by site to e-commerce storefronts so promised dates reflect real stock.
  • 02 Push confirmed sales orders to a 3PL or WMS and write shipment confirmations back to Rootstock.
  • 03 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.
  • 04 Write enriched or sourced Candidates from external tools into Greenhouse and keep contact fields refreshed as data changes.

Common sync patterns

Reporting lines drive approvals

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

Where Greenhouse runs payroll: labor cost in the books

Pay and compensation data from Greenhouse posts into Rootstock 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 Rootstock ERP is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

How changes propagate between Greenhouse and Rootstock ERP

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.

Greenhouse Rootstock 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 Rootstock ERP through its API, with automatic retries and rate-limit backoff.

Rootstock ERP Greenhouse Sub-second propagation

DetectionChanges in Rootstock ERP are captured at the source via change data capture — no polling loop against its API. Salesforce Change Data Capture on Rootstock custom objects where enabled (entity selection limits apply).

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

Rate-limit considerations

  • 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.
  • Rootstock ERP: Consumes the Salesforce org's daily API request allocation, shared with other integrations.
