Why teams connect Klaviyo and SAP

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

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Campaigns, Flows, Templates, Catalog Items in Klaviyo with Business Partners, Materials (Products), Sales Orders, Purchase Orders in SAP 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

  • Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • Publish plant-level inventory to e-commerce and planning systems on change or on schedule.
  • Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.

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 carries account records

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

Where Klaviyo collects payments: transactions post through

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