Why teams connect Extensiv (3PL Central) and Linnworks

Two ERPs, one set of facts: Stacksync keeps Extensiv (3PL Central) and Linnworks 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 Items, Inventory, Orders, Receivers in Extensiv (3PL Central) with Locations, Purchase Orders, Suppliers, Channel Listings in Linnworks 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

  • Keep item masters aligned between a merchant's ERP and the 3PL warehouse so receiving and picking use consistent SKUs.
  • Mirror on-hand inventory by warehouse into merchant systems to drive available-to-promise and reorder logic.
  • 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

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.
