Why teams connect Extensiv (3PL Central) and Klaviyo

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Klaviyo and Extensiv (3PL Central).

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Klaviyo is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Templates, Catalog Items, Tags, Profiles in Klaviyo with Inventory adjustments, Customers, Items, Inventory in Extensiv (3PL Central) bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
  • Consolidate order and shipment data across 3PL clients into a reporting database for billing and SLA tracking.
  • Sync commerce or ERP orders into 3PL Central for fulfillment, and sync shipment confirmations with tracking numbers back.

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.
