Why teams connect Close and Intercom

Run Close and Intercom 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 Users, Smart Views, Leads, Contacts in Close with Articles, Contacts, Companies, Conversations in Intercom 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

  • Two-way sync between Close and a billing or ERP system so closed-won opportunities create customers and invoices automatically.
  • Keep Close contacts aligned with a marketing automation platform so outreach lists stay current.
  • Keep custom data attributes updated from billing or ERP systems so message segments reflect current plan and spend
  • Route qualified leads from Intercom conversations into the CRM as leads or opportunities in near real time

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 Intercom

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.

Close objects Intercom objects
Custom Activities User-defined activity types with their own custom fields, mapped like standard activities. Companies Company records group contacts and carry plan and account attributes used in segmentation.
Custom Fields Org-specific fields on leads, contacts, and opportunities; addressed by stable field ids in syncs. Conversations Support and sales threads sync outward for analytics and CRM context.
Users Sales reps referenced as owners on leads, opportunities, and activities. Tickets Structured ticket records track issues alongside conversational threads.
Smart Views Saved lead searches that can scope which records a segment-based sync pulls. Data Events Behavioral events pushed in from product databases trigger messages and flows.
Leads The top-level record in Close; represents a company and holds its contacts, opportunities, and activity history. Custom Data Attributes Typed custom fields on contacts and companies hold synced billing and usage data.
Contacts People nested under a lead, with emails and phone numbers used for outreach syncs. Tags Labels applied to contacts, companies, and conversations sync for routing and reporting.
