Why teams connect Linnworks and Unleashed Software

Two ERPs, one set of facts: Stacksync keeps Linnworks and Unleashed Software 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 Locations, Purchase Orders, Suppliers, Channel Listings in Linnworks with Invoices, Products, Stock On Hand, Sales Orders in Unleashed Software 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

  • Mirror processed orders, refunds, and returns into a warehouse for margin reporting across channels
  • Sync product and listing data with a PIM so channel listings stay aligned with the catalog
  • Mirror Purchase Orders and supplier data to a data warehouse for procurement reporting.
  • Sync Customers bi-directionally with a CRM so credit terms and delivery addresses match everywhere.

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.

Two-tier roll-up

Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.
