Why teams connect IBM AS/400 and Linnworks

Give your engineers Linnworks's data in IBM AS/400: 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 Stock Items, Stock Levels, Locations, Purchase Orders from Linnworks into IBM AS/400 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 IBM AS/400 sync back into Linnworks with its validations respected.

Common use cases

  • Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
  • Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
  • Keep stock levels consistent between Linnworks and external systems so multichannel listings stay aligned with sellable stock

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Linnworks interface, limits, and retries.

React to ERP changes

Updates in Linnworks arrive as row changes in IBM AS/400, 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 IBM AS/400 for provisioning, access, and reporting systems that read from the database.

What you can sync between IBM AS/400 and Linnworks

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.

IBM AS/400 objects Linnworks objects
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Shipping Services Carrier and service definitions support label and tracking data in order syncs.
Libraries The schema-equivalent containers that scope which files a sync reads. Open Orders Unshipped orders aggregated from sales channels sync into ERPs and fulfillment systems.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Processed Orders Completed orders feed accounting and warehouse-based margin reporting.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Stock Items SKU records keep product data aligned with ERPs and PIMs.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability.
Rows / records The unit of read and write, accessed via SQL or record-level access. Locations Warehouse and fulfillment location records scope stock data during mapping.
