Why teams connect Customer.io and Sage X3
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Customer.io and Sage X3.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Sales Orders, Purchase Orders, Work Orders, Stock / Inventory by site in Sage X3 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 account-level objects and their person relationships for B2B messaging keyed to company attributes.
- Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
- Publish per-site stock levels to storefronts and a WMS on a schedule.
- Replicate GL journals and sales history to a warehouse for multi-company, multi-legislation reporting.
Where Customer.io faces customers and Sage X3 carries account records
Order, invoice, or account status from Sage X3 appears alongside the customer in Customer.io, so front-line teams answer from live data.
Where Customer.io collects payments: transactions post through
Payment events sync into Sage X3 as they occur, keeping the enterprise records current without manual entry.
Where Sage X3 is the HR or people system of record
Worker and organization data from Sage X3 stays current in Customer.io, so the tools people use daily reflect the org as it actually is.
