Why teams connect Customer.io and Extensiv (3PL Central)

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

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Customer.io 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Objects, Events, Segments, Campaigns in Customer.io with Warehouses, Inventory adjustments, Customers, Items 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

  • Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
  • Push CRM segments and lead status into Customer.io so messaging respects sales stage.
  • Sync commerce or ERP orders into 3PL Central for fulfillment, and sync shipment confirmations with tracking numbers back.
  • Keep item masters aligned between a merchant's ERP and the 3PL warehouse so receiving and picking use consistent SKUs.

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