Why teams connect Lever and Sage X3

Sync the workers, org structure, and cost centers that Sage X3 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. Sage X3 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 Purchase Orders, Work Orders, Stock / Inventory by site, Bills of Material in Sage X3 with Feedback, Interviews, Notes and Contacts, Opportunities 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 Sage X3 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 Push orders from e-commerce or EDI channels into X3 sales orders and return delivery status.
  • 02 Publish per-site stock levels to storefronts and a WMS on a schedule.
  • 03 Consolidate Feedback, Interviews, and Notes into a warehouse for interviewer scorecard and time-to-fill reporting.
  • 04 Write enriched Sources, Tags, and Contact data back onto Opportunities from an outbound sourcing pipeline.

Common sync patterns

Where Lever runs payroll: labor cost in the books

Pay and compensation data from Lever posts into Sage X3 as labor cost, so finance sees workforce spend without re-entering it by hand.

Where Lever is the worker system of record: one employee master

When a worker is hired, moved, or offboarded in Lever, the matching employee record in Sage X3 is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

New hires ready to transact in Sage X3

A new person set up in Lever becomes an employee record in Sage X3 in time to submit expenses, enter time, or approve a purchase, without waiting on manual setup.

What you can sync between Lever and Sage X3

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 Sage X3 objects How this pairing syncs
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. Work Orders Production orders read by MES and scheduling integrations. Notes and Contacts is specific to Lever and Work Orders to Sage X3 — 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. Stock / Inventory by site On-hand and allocated quantities per site, synced to storefronts and WMS. Opportunities is specific to Lever and Stock / Inventory by site to Sage X3 — 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. Bills of Material Product structures read for planning and costing. Postings is specific to Lever and Bills of Material to Sage X3 — 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. GL Journals Financial entries replicated to warehouses for group reporting. Requisitions is specific to Lever and GL Journals to Sage X3 — each maps to any object or custom field on the other side.
Offers Offer records attached to an Opportunity with status and offer-form fields; exposed read-only through GET /opportunities/:id/offers, so they sync outbound to an HRIS or onboarding system when a candidate reaches the offer stage. Deliveries Shipment documents synced to logistics providers and customer portals. Offers is specific to Lever and Deliveries to Sage X3 — each maps to any object or custom field on the other side.
Users Lever team members (recruiters, hiring managers) with configurable roles; can be created via POST /users, deactivated, and reactivated through the API. Business Partners (Customers and Suppliers) Shared partner master synced with CRMs and procurement systems. Users is specific to Lever and Business Partners (Customers and Suppliers) to Sage X3 — each maps to any object or custom field on the other side.

How changes propagate between Lever and Sage X3

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 Sage X3 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 applied to Sage X3 as a row-level write, with types converted between the two schemas.

Sage X3 Lever Interval-based propagation

DetectionStacksync polls Sage X3 for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled polling.

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.
