Why teams connect E2 Shop System and Kustomer

Flow E2 Shop System data into Kustomer 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 Kustomer, so Kustomer always reflects the current state of E2 Shop System — without exports, scripts, or schedulers.

Kustomer holds the customer relationship; E2 Shop System runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.

Common use cases

  • Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
  • Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
  • Keep purchase order data visible to planning or supplier-facing tools without direct ERP access.
  • Replicate job and work order status into a reporting database to power shop-floor and delivery dashboards.

Where E2 Shop System manages people and org data: keep Kustomer aligned

Owners, territories, and org structure informed by E2 Shop System stay current in Kustomer.

Where E2 Shop System handles order-to-cash: closed-won flows through

A deal won in Kustomer creates or updates the customer in E2 Shop System with clean data, so fulfillment and invoicing start without re-entry.

Where E2 Shop System is the finance system of record: money status on the account

Invoice and payment state from E2 Shop System shows on the account in Kustomer, so reps see balances before promising the next order.
