Why teams connect Kustomer and Snapfulfil

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

Kustomer holds the customer relationship; Snapfulfil 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 Shipments, Warehouse locations, Returns, Sales orders in Snapfulfil 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

  • Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
  • Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • Sync the item master from the ERP so new SKUs are receivable in the warehouse immediately
  • Mirror fulfillment activity into a database for operational reporting outside the WMS

One customer master

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

Where Snapfulfil manages people and org data: keep Kustomer aligned

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

Where Snapfulfil handles order-to-cash: closed-won flows through

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