Why teams connect Lever and SAP

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

Lever 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. SAP 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 GL Accounts and Journal Entries, Production Orders, Inventory / Stock, Cost Centers in SAP with Notes and Contacts, Opportunities, Postings, Requisitions in Lever 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 SAP 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 journal entries and billing documents to a warehouse for finance analytics without loading the ERP.
  • 02 Keep MES and WMS systems aligned with production orders and goods movements.
  • 03 Write enriched Sources, Tags, and Contact data back onto Opportunities from an outbound sourcing pipeline.
  • 04 Two-way sync Opportunities and their Stages between Lever and a Postgres database so recruiting ops and analysts query the pipeline in SQL while recruiters keep working in Lever.

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 SAP roll up to the same structure Lever maintains.

Reporting lines drive approvals

Manager and reporting-hierarchy changes in Lever keep expense and purchase approval chains in SAP pointed at the right people.

Where Lever runs payroll: labor cost in the books

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

What you can sync between Lever and SAP

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.

Lever objects SAP objects How this pairing syncs
Feedback Interview feedback and scorecard forms attached to Opportunities; created via POST /opportunities/:id/feedback and consolidated into a warehouse for interviewer analytics. GL Accounts and Journal Entries Financial postings replicated to warehouses for group finance analytics. Feedback is specific to Lever and GL Accounts and Journal Entries to SAP — each maps to any object or custom field on the other side.
Interviews Scheduled interview panel events with times and interviewers; read for scheduling reporting and time-to-hire metrics, and creatable via the panels endpoint. Production Orders Manufacturing orders exchanged with MES and scheduling systems. Interviews is specific to Lever and Production Orders to SAP — each maps to any object or custom field on the other side.
Notes and Contacts Free-text Notes on Opportunities plus the underlying Contact (person) that dedupes multiple Opportunities; notes are posted via POST /opportunities/:id/notes and contact-level tags, sources, and links can be added back for attribution. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. Notes and Contacts is specific to Lever and Inventory / Stock to SAP — each maps to any object or custom field on the other side.
Opportunities The core pipeline record for a candidate applying to a role; replaced the deprecated Candidates endpoint. Created via POST /opportunities and updated (stage, archive, links, tags, sources, files) through the API, and synced two-way with a database or HRIS. Cost Centers Controlling masters read for mapping costs in finance integrations. Opportunities is specific to Lever and Cost Centers to SAP — each maps to any object or custom field on the other side.
Postings Job posting records with categories, apply URLs, workplace type, and requisition codes. Can be created via POST /postings and read into a warehouse for open-role reporting. Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs. Postings is specific to Lever and Business Partners to SAP — each maps to any object or custom field on the other side.
Requisitions Headcount/requisition records with custom requisition fields, tied to Postings; read via GET /requisitions and synced to an HRIS to reconcile approved headcount against open roles. Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. Requisitions is specific to Lever and Materials (Products) to SAP — each maps to any object or custom field on the other side.

How changes propagate between Lever and SAP

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.

Lever SAP Sub-second propagation

DetectionLever notifies Stacksync of record changes through webhook events. Webhooks for candidate and application lifecycle events (applicationCreated, candidateStageChange, candidateArchiveStateChange, candidateHired,.

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

SAP Lever Sub-second propagation

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

Rate-limit considerations

  • Lever: 10 requests/second per API key with a token-bucket burst to ~20/s; POSTs that create candidates/applications are throttled to roughly 2/second. Sustained overage returns 429 with Retry-After. List endpoints are cursor-paginated at up to 100 records per page.
  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.
