Why teams connect Close and Copper CRM

Run Close and Copper CRM 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 Custom Activities, Custom Fields, Users, Smart Views in Close with Activities, Tasks, Projects, Pipelines in Copper CRM 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 Push call, SMS, and email activity data into a warehouse for rep performance and outreach-cadence analysis.
  • 02 Write product usage or firmographic data from an internal database onto Close lead custom fields to prioritize follow-up.
  • 03 Sync Copper people and opportunities into a warehouse for pipeline reporting beyond Copper's native dashboards.
  • 04 Two-way sync between Copper and an accounting or invoicing system so won opportunities become customers and invoices.

Common sync patterns

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.

Migration with a parallel run

When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.

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.

What you can sync between Close and Copper CRM

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.
