Why teams connect Kustomer and Sage X3

Close the gap between front office and back office: Kustomer and Sage X3 share customers and status in real time, in both directions.

Kustomer holds the customer relationship; Sage X3 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.

Stacksync syncs Messages, Companies, Custom Objects (Klasses), Users in Kustomer with Sales Orders, Purchase Orders, Work Orders, Stock / Inventory by site in Sage X3 field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.

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
  • Sync business partners and products between Sage X3 and a CRM so global sales teams quote from current ERP masters.
  • Push orders from e-commerce or EDI channels into X3 sales orders and return delivery status.

Where Sage X3 handles order-to-cash: closed-won flows through

A deal won in Kustomer creates or updates the customer in Sage X3 with clean data, so fulfillment and invoicing start without re-entry.

Where Sage X3 is the finance system of record: money status on the account

Invoice and payment state from Sage X3 shows on the account in Kustomer, so reps see balances before promising the next order.

One customer master

Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.
