Why teams connect E2 Shop System and Klaviyo

Flow E2 Shop System data into Klaviyo in real time — no exports, no schedulers, no custom scripts.

E2 Shop System is a read-only source: Stacksync reads its data in real time and delivers it into Klaviyo, so Klaviyo always reflects the current state of E2 Shop System — without exports, scripts, or schedulers.

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

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
  • Replicate job and work order status into a reporting database to power shop-floor and delivery dashboards.
  • Sync customer and invoice data to accounting or CRM so the front office is not re-keying from the ERP.

Where E2 Shop System is the HR or people system of record

Worker and organization data from E2 Shop System 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 E2 Shop System carries account records

Order, invoice, or account status from E2 Shop System appears alongside the customer in Klaviyo, so front-line teams answer from live data.
