Why teams connect Linnworks and SAP

Two ERPs, one set of facts: Stacksync keeps Linnworks and SAP consistent in real time, whether they split the business or one is replacing the other.

Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.

Stacksync syncs Purchase Orders, Suppliers, Channel Listings, Returns & Refunds in Linnworks with Billing Documents, GL Accounts and Journal Entries, Production Orders, Inventory / Stock in SAP bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.

Common use cases

  • 01 Mirror processed orders, refunds, and returns into a warehouse for margin reporting across channels
  • 02 Sync product and listing data with a PIM so channel listings stay aligned with the catalog
  • 03 Keep MES and WMS systems aligned with production orders and goods movements.
  • 04 Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.

Common sync patterns

Migration in parallel

When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

Split by function

Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.

What you can sync between Linnworks 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.

Linnworks objects SAP objects How this pairing syncs
Purchase Orders Replenishment POs sync with suppliers and accounting systems. Purchase Orders Procurement documents synced with supplier portals and spend tools. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Channel Listings Marketplace and webstore listing mappings tie channel products to internal SKUs. Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals. Channel Listings is specific to Linnworks and Outbound Deliveries to SAP — each maps to any object or custom field on the other side.
Returns & Refunds Post-sale records flow to finance and support systems. Billing Documents Invoices read for AR status and replicated for revenue reporting. Returns & Refunds is specific to Linnworks and Billing Documents to SAP — each maps to any object or custom field on the other side.
Shipping Services Carrier and service definitions support label and tracking data in order syncs. GL Accounts and Journal Entries Financial postings replicated to warehouses for group finance analytics. Shipping Services is specific to Linnworks and GL Accounts and Journal Entries to SAP — each maps to any object or custom field on the other side.
Open Orders Unshipped orders aggregated from sales channels sync into ERPs and fulfillment systems. Production Orders Manufacturing orders exchanged with MES and scheduling systems. Open Orders is specific to Linnworks and Production Orders to SAP — each maps to any object or custom field on the other side.
Processed Orders Completed orders feed accounting and warehouse-based margin reporting. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. Processed Orders is specific to Linnworks and Inventory / Stock to SAP — each maps to any object or custom field on the other side.

How changes propagate between Linnworks 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.

Linnworks SAP Interval-based propagation

DetectionStacksync polls Linnworks for changes on an incremental schedule, reading only records changed since the previous pass. Polling on order and stock endpoints.

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

SAP Linnworks Sub-second propagation

DetectionSAP notifies Stacksync of record changes through webhook events. Business events via SAP Event Mesh on S/4HANA.

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

Rate-limit considerations

  • Linnworks: Per-endpoint rate limits apply on the Linnworks API.
  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.
