Why teams connect Klaviyo and SAP S/4HANA

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Klaviyo and SAP S/4HANA.

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Templates, Catalog Items, Tags, Profiles in Klaviyo with Sales Orders, Purchase Orders, Products / Materials, Billing Documents (Invoices) in SAP S/4HANA 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 suppression and consent status consistent between Klaviyo and other email or SMS tools
  • Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
  • Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.
  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.

Where SAP S/4HANA is the HR or people system of record

Worker and organization data from SAP S/4HANA 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.

Where Klaviyo faces customers and SAP S/4HANA carries account records

Order, invoice, or account status from SAP S/4HANA appears alongside the customer in Klaviyo, so front-line teams answer from live data.

What you can sync between Klaviyo and SAP S/4HANA
