Why teams connect Kustomer and NetSuite

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

Kustomer holds the customer relationship; NetSuite 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 Conversations, Messages, Companies, Custom Objects (Klasses) in Kustomer with Bin Transfer, Currency Rate, Price Level, Term in NetSuite 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

  • Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
  • Sync customers, sales orders, and invoices to an operational Postgres database so teams query ERP data without writing SuiteScript.
  • Expose item and inventory data to internal applications through a continuously synced database table.

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

Invoice and payment state from NetSuite 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.

Where NetSuite manages people and org data: keep Kustomer aligned

Owners, territories, and org structure informed by NetSuite stay current in Kustomer.
