Why teams connect Greenhouse and Syspro

Sync the workers, org structure, and cost centers that Syspro 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. Syspro 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 AR invoices, GL journals, Warehouses, Customers in Syspro with Jobs, Offers, Scorecards, Scheduled Interviews 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 Syspro 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 Extract job and WIP data into a warehouse for production and costing reports
  • 02 Post shipment confirmations from logistics systems back against SYSPRO sales orders
  • 03 Write enriched or sourced Candidates from external tools into Greenhouse and keep contact fields refreshed as data changes.
  • 04 Stream Jobs, Departments, and Offices into a reporting database for recruiting funnel and time-to-fill dashboards.

Common sync patterns

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 Syspro is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

New hires ready to transact in Syspro

A new person set up in Greenhouse becomes an employee record in Syspro in time to submit expenses, enter time, or approve a purchase, without waiting on manual setup.

One org structure

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

What you can sync between Greenhouse and Syspro

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 Syspro objects How this pairing syncs
Users Greenhouse users (recruiters, hiring managers); read and written, and referenced by the On-Behalf-Of header on every write. Suppliers AP supplier records synced with procurement and payment systems. Users is specific to Greenhouse and Suppliers to Syspro — 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. Inventory items The stock master, kept aligned with WMS and e-commerce catalogs. Departments and Offices is specific to Greenhouse and Inventory items to Syspro — 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. Sales orders Orders written in from storefronts and CRMs, with status read back out. Candidates is specific to Greenhouse and Sales orders to Syspro — 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. Purchase orders Procurement documents synced with supplier portals and receiving. Applications is specific to Greenhouse and Purchase orders to Syspro — 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. Jobs (work orders) Manufacturing jobs and WIP tracked for production reporting. Jobs is specific to Greenhouse and Jobs (work orders) to Syspro — each maps to any object or custom field on the other side.
Offers Offer records tied to an Application with status and custom offer fields; readable and patchable, commonly synced to HRIS on hire. Bills of materials Product structures referenced when syncing manufacturing data. Offers is specific to Greenhouse and Bills of materials to Syspro — each maps to any object or custom field on the other side.

How changes propagate between Greenhouse and Syspro

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 Syspro 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 Syspro through its API, with automatic retries and rate-limit backoff.

Syspro Greenhouse Interval-based propagation

DetectionStacksync polls Syspro for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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.
  • Syspro: Throughput depends on the customer's server sizing; many deployments are on-premise.
