Why teams connect Acumatica and Klaviyo

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

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Lists, Segments, Events, Metrics in Klaviyo with Opportunities and Cases, Customers, Vendors, Sales Orders 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 customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • Mirror stock items and quantities to external channels so availability stays accurate across systems.
  • Replicate journal transactions and financial data into a SQL database for reporting and consolidation.

Where Klaviyo 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 Klaviyo, 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.
