Why teams connect Kustomer and Dynamics 365 Business Central
Close the gap between front office and back office: Kustomer and Dynamics 365 Business Central share customers and status in real time, in both directions.
Kustomer holds the customer relationship; Dynamics 365 Business Central 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 Customers, Conversations, Messages, Companies in Kustomer with Dimensions, Payments, Customers, Vendors in Dynamics 365 Business Central 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 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
- 02 Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
- 03 Create sales orders in Business Central automatically from e-commerce or CRM order records, and sync fulfillment status back.
- 04 Mirror items and inventory levels into external channels so stock data stays current outside the ERP.
Common sync patterns
One customer master
Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.
Where Dynamics 365 Business Central manages people and org data: keep Kustomer aligned
Owners, territories, and org structure informed by Dynamics 365 Business Central stay current in Kustomer.
Where Dynamics 365 Business Central handles order-to-cash: closed-won flows through
