Why teams connect Acumatica and Customer.io

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

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Customers, Vendors, Sales Orders, Invoices in Acumatica 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.
  • Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
  • Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.

Where Customer.io collects payments: transactions post through

Payment events sync into Acumatica as they occur, keeping the enterprise records current without manual entry.

Where Acumatica is the HR or people system of record

Worker and organization data from Acumatica stays current in Customer.io, so the tools people use daily reflect the org as it actually is.

Master data corrections travel

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