Why teams connect Acumatica and Kustomer
Close the gap between front office and back office: Kustomer and Acumatica share customers and status in real time, in both directions.
Kustomer holds the customer relationship; Acumatica 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 Custom Objects (Klasses), Users, Teams, Tags in Kustomer with Journal Transactions, Projects, Opportunities and Cases, Customers in Acumatica 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
- 01 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
- 02 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
- 03 Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.
- 04 Mirror stock items and quantities to external channels so availability stays accurate across systems.

Stacksync's field mapping accounts for these differences between Acumatica and Kustomer without custom code.
