Why teams connect Customer.io and TikTok Shop

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Customer.io and TikTok Shop.

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Newsletters, People, Objects, Events in Customer.io with Promotions, Shops, Products, SKUs in TikTok Shop 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 unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
  • Push inventory levels from the warehouse or ERP to TikTok Shop to prevent overselling on live and video commerce
  • Sync product catalogs and pricing from a PIM or ERP into shop listings

Master data corrections travel

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