Why teams connect Kustomer and Twenty CRM

Run Kustomer and Twenty 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 Objects (Klasses), Users, Teams, Tags in Kustomer with Notes, Custom Objects, Attachments, Workspace Members in Twenty 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

  • Escalate conversation-derived signals into the CRM as tasks or opportunities
  • Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
  • Run a continuous sync from a legacy CRM into Twenty during a migration so both systems stay usable through cutover.
  • Two-way sync of People and Companies between Twenty and a production Postgres database so engineers can query CRM data with SQL.

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.
