Why teams connect Greenhouse and Sage 300
Sync the workers, org structure, and cost centers that Sage 300 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. Sage 300 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 and Receipts, AR Customers, AP Vendors, GL Accounts in Sage 300 with Scorecards, Scheduled Interviews, Users, Departments and Offices 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 Sage 300 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 Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
- 02 Sync AR customers, invoices, and balances into a CRM for multi-currency account visibility.
- 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
Reporting lines drive approvals
Manager and reporting-hierarchy changes in Greenhouse keep expense and purchase approval chains in Sage 300 pointed at the right people.
Where Greenhouse runs payroll: labor cost in the books
Pay and compensation data from Greenhouse posts into Sage 300 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 Sage 300 is created, updated, or deactivated, so the business system reflects the workforce as it actually is.
What you can sync between Greenhouse and Sage 300
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 | Sage 300 objects | How this pairing syncs | |
|---|---|---|---|
| Offers Offer records tied to an Application with status and custom offer fields; readable and patchable, commonly synced to HRIS on hire. | Purchase Orders Procurement documents read for spend visibility and receiving. | Offers is specific to Greenhouse and Purchase Orders to Sage 300 — each maps to any object or custom field on the other side. | |
| Scorecards Interviewer feedback and ratings tied to interviews; read-only in Harvest, exported to a warehouse for interview analytics. | Inventory Items Item master with costing and quantities, synced to storefronts and WMS. | Scorecards is specific to Greenhouse and Inventory Items to Sage 300 — each maps to any object or custom field on the other side. | |
| Scheduled Interviews Interview events with interviewers, times, and rooms; full create/update/delete support for calendar and reporting syncs. | AR Invoices and Receipts Billing and payment records replicated for cash and revenue reporting. | Scheduled Interviews is specific to Greenhouse and AR Invoices and Receipts to Sage 300 — 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. | AR Customers Receivables customer master synced to CRMs and billing tools. | Users is specific to Greenhouse and AR Customers to Sage 300 — 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. | AP Vendors Payables vendor master synced with procurement and payment systems. | Departments and Offices is specific to Greenhouse and AP Vendors to Sage 300 — 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. | GL Accounts Chart of accounts read for transaction mapping across integrations. | Candidates is specific to Greenhouse and GL Accounts to Sage 300 — each maps to any object or custom field on the other side. |
How changes propagate between Greenhouse and Sage 300
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 Sage 300 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 applied to Sage 300 as a row-level write, with types converted between the two schemas.
Sage 300 Greenhouse Interval-based propagation
DetectionStacksync polls Sage 300 for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled 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.

FAQ
Greenhouse and Sage 300 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Greenhouse and Sage 300: authenticate both systems, choose the objects to sync (such as Greenhouse's Offers and Scorecards), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Sage 300: Sage 300 (formerly Accpac) stores each company's data in its own SQL Server database with module-prefixed tables, so direct SQL reads are a common integration path on-prem. Greenhouse: Harvest API keys are permission-scoped per endpoint, so a sync only reaches the objects the key is explicitly granted. Stacksync's field mapping accounts for these differences between Greenhouse and Sage 300 without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Greenhouse and Sage 300 records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Greenhouse and Sage 300 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Greenhouse–Sage 300 integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Greenhouse and Sage 300. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Greenhouse: HMAC-SHA256 signed webhooks for candidate, application, job, and interview events, plus polling list endpoints with created_after / updated_after / last_activity_after filters. On Sage 300: Scheduled polling; batch-oriented modules with no webhook surface. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
