Two-way sync
Changes in Copper CRM or Kustomer instantly reflect in both systems. No stale data, no manual imports.
Keep Copper CRM and Kustomer in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 People, Companies, Leads, Opportunities in Copper CRM with Custom Objects (Klasses), Users, Teams, Tags 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.
Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
Deal stage and value on shared accounts stay visible from either CRM.
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
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.
| Copper CRM objects | Kustomer objects | |
|---|---|---|
| Companies Organization records linked to people and opportunities. | Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | |
| Leads Unqualified prospects kept separate from People until converted. | Conversations Support threads across channels sync outward for analytics and CRM context. | |
| Opportunities Deals tracked through pipelines and stages; synced for revenue reporting. | Messages Individual messages within conversations support full-thread replication. | |
| Activities Logged emails, calls, meetings, and notes attached to records. | Companies Organization records group customers and map to CRM accounts. | |
| Tasks To-dos with due dates and assignees, usable in workload syncs. | Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. | |
| Projects Post-sale work records Copper offers alongside classic CRM objects. | Users Agent records map conversation ownership to people in other systems. |

Change detection on Copper CRM: Webhook subscriptions for record create/update/delete events; polling as fallback. On Kustomer: Outbound webhooks on record events, plus polling for backfill. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Copper CRM side: People, Companies, Leads, Opportunities, plus custom fields where Copper CRM exposes them. On the Kustomer side: Custom Objects (Klasses), Users, Teams, Tags. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
