Why teams connect Linnworks and OpenSearch

Give your engineers Linnworks's data in OpenSearch: read it with normal queries, write back through the sync, and skip the ERP API entirely.

ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.

Stacksync mirrors Locations, Purchase Orders, Suppliers, Channel Listings from Linnworks into OpenSearch and keeps both sides consistent in real time. Whatever Linnworks is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in OpenSearch sync back into Linnworks with its validations respected.

Common use cases

  • Sync product catalogs from an ERP or database into the indexes that back storefront search.
  • Keep Postgres as the source of truth while mirroring rows to OpenSearch for full-text and vector queries.
  • Sync product and listing data with a PIM so channel listings stay aligned with the catalog
  • Push customer and order data to a CRM or marketing platform for post-purchase campaigns

React to ERP changes

Updates in Linnworks arrive as row changes in OpenSearch, so jobs and triggers can respond as the business record changes.

Where Linnworks is the HR system of record: people data for internal systems

Worker and org records stay current in OpenSearch for provisioning, access, and reporting systems that read from the database.

Controlled write-back

Choose exactly which tables and fields may flow from OpenSearch back into Linnworks, keeping the ERP authoritative.

What you can sync between Linnworks and OpenSearch

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 OpenSearch objects
Processed Orders Completed orders feed accounting and warehouse-based margin reporting. Indexes The core container; synced records land in indexes with defined mappings
Stock Items SKU records keep product data aligned with ERPs and PIMs. Documents JSON records written via the index and bulk APIs and read via search queries
Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability. Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills
Locations Warehouse and fulfillment location records scope stock data during mapping. Index templates Mapping and settings presets applied to new indexes a sync creates
Purchase Orders Replenishment POs sync with suppliers and accounting systems. Ingest pipelines Server-side processors that transform documents as they are written
Suppliers Vendor records keep procurement data consistent across tools. Data streams Append-oriented time-series storage for logs and events pushed from source systems
