Why teams connect Copper CRM and Kustomer

Run Copper 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 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.

Common use cases

  • 01 Enrich Copper records with product usage or firmographic data from an internal database to guide follow-up.
  • 02 Mirror Copper data into Postgres so internal tools can query CRM state without extra API calls.
  • 03 Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
  • 04 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools

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 Copper 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.

How changes propagate between Copper CRM and Kustomer

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Copper CRM Kustomer Sub-second propagation

DetectionCopper CRM notifies Stacksync of record changes through webhook events. Webhook subscriptions for record create/update/delete events.

DeliveryEach detected change is written to Kustomer through its API, with automatic retries and rate-limit backoff.

Kustomer Copper CRM Sub-second propagation

DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.

DeliveryEach detected change is written to Copper CRM through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations
