Why teams connect ConnectWise and Kustomer

Sync what happens in ConnectWise with the customer records in Kustomer, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever ConnectWise holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Agreements, Projects, Time Entries, Invoices in ConnectWise to Customers, Conversations, Messages, Companies in Kustomer with bi-directional, real-time sync. Activity and record changes in ConnectWise update the matching contact or account in Kustomer, and CRM data flows the other way wherever ConnectWise can store and use it.

Common use cases

  • Reconcile ConnectWise invoices and agreements against the accounting system to catch billing gaps.
  • Keep configuration (asset) records aligned with an external CMDB or RMM tool.
  • 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

Where ConnectWise handles support or shared inboxes

Tickets and conversations attach to the right contact and account in Kustomer, so sales sees open issues before the next call.

Where ConnectWise supplies contact or company data

Enriched fields land directly on records in Kustomer, and refreshes keep them from going stale.

Where ConnectWise processes payments

Charges, refunds, and subscription changes appear on the account in Kustomer, so revenue context lives with the relationship.
