Why teams connect Freshworks CRM and Kustomer
Run Freshworks CRM and Kustomer side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.
Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.
Stacksync syncs Accounts, Deals, Tasks, Appointments in Freshworks CRM with Notes, Customers, Conversations, Messages in Kustomer in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.
Common use cases
- 01 Two-way sync accounts and deals with an ERP so quotes and invoices reference the same customer records.
- 02 Keep list membership aligned with segments computed in the warehouse.
- 03 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
- 04 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
Common sync patterns
Divisional or regional split
Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
Where both track pipeline: deal visibility across systems
Deal stage and value on shared accounts stay visible from either CRM.
Post-acquisition consolidation
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
What you can sync between Freshworks CRM and Kustomer
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Freshworks CRM objects | Kustomer objects | How this pairing syncs | |
