Why teams connect Greenhouse and QAD ERP

Sync the workers, org structure, and cost centers that QAD 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. QAD 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 Customers, Suppliers, Sales orders, Purchase orders in QAD ERP with Users, Departments and Offices, Candidates, Applications 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 QAD 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 Replicate inventory and work-order data into a warehouse for supply chain analytics across plants.
  • 02 Push EDI orders from trading partners into QAD as sales orders.
  • 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

One org structure

Departments, cost centers, and locations that both systems reference stay in agreement, so labor cost, approvals, and reporting in QAD ERP roll up to the same structure Greenhouse maintains.

Reporting lines drive approvals

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

Where Greenhouse runs payroll: labor cost in the books

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

What you can sync between Greenhouse and QAD ERP

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.

Greenhouse objects QAD ERP objects How this pairing syncs
Scheduled Interviews Interview events with interviewers, times, and rooms; full create/update/delete support for calendar and reporting syncs. Suppliers Vendor master data aligned with procurement and AP automation tools Scheduled Interviews is specific to Greenhouse and Suppliers to QAD ERP — each maps to any object or custom field on the other side.
Users Greenhouse users (recruiters, hiring managers); read and written, and referenced by the On-Behalf-Of header on every write. Sales orders Demand records written in from EDI or e-commerce and read out for status Users is specific to Greenhouse and Sales orders to QAD ERP — each maps to any object or custom field on the other side.
Departments and Offices Org structure attached to Jobs; read and written to keep reporting hierarchies aligned with an HRIS or warehouse. Purchase orders Procurement documents mirrored to planning and finance systems Departments and Offices is specific to Greenhouse and Purchase orders to QAD ERP — each maps to any object or custom field on the other side.
Candidates Person records with contact details, tags, and custom fields; read and written via Harvest, often created from sourcing or enrichment pipelines. Work orders Production records replicated for scheduling and shop-floor analytics Candidates is specific to Greenhouse and Work orders to QAD ERP — each maps to any object or custom field on the other side.
Applications Links a Candidate to a Job; carries current stage, status, and source. Movable, rejectable, and hireable through Harvest write calls. Inventory balances Stock levels by site and location, synced for multi-plant visibility Applications is specific to Greenhouse and Inventory balances to QAD ERP — each maps to any object or custom field on the other side.
Jobs Requisitions with openings, hiring team, departments, and offices; created and patched via Harvest, read out for funnel and time-to-fill reporting. General ledger transactions Financial postings exported for consolidated reporting Jobs is specific to Greenhouse and General ledger transactions to QAD ERP — each maps to any object or custom field on the other side.

How changes propagate between Greenhouse and QAD 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 QAD 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 QAD ERP through its API, with automatic retries and rate-limit backoff.

QAD ERP Greenhouse Interval-based propagation

DetectionStacksync polls QAD ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on the API surface.

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.
  • QAD ERP: Subject to instance capacity and the platform's API limits.
