Why teams connect HubSpot and Salesforce

Run HubSpot and Salesforce 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 Deal, Line Item, Product, Ticket in HubSpot with Cases, Campaigns, Tasks and Events, Products and Price Books in Salesforce 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

  • Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
  • Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.
  • Consolidate multiple Salesforce orgs into a single database for cross-org reporting after an acquisition.
  • Sync Accounts, Contacts, and Opportunities bi-directionally with Postgres so engineering teams read and write CRM data with plain SQL.

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.

Where both track pipeline: deal visibility across systems

Deal stage and value on shared accounts stay visible from either CRM.

What you can sync between HubSpot and Salesforce

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.

HubSpot objects Salesforce objects
Product Synced with incremental and full sync per the Stacksync docs. Custom Objects Org-specific tables with the __c suffix; discoverable via describe metadata so field mappings can be generated.
Ticket Synced with incremental and full sync per the Stacksync docs. Accounts Company records that anchor most syncs; typically mapped to customer tables in a database or ERP.
Quote Synced with incremental and full sync per the Stacksync docs. Contacts People linked to Accounts; synced two-way with marketing, support, and warehouse person records.
Goal Synced with incremental and full sync per the Stacksync docs. Leads Unqualified prospects; often written into Salesforce from enrichment or product-signup pipelines.
Owner Synced with incremental and full sync per the Stacksync docs. Opportunities Deal records with stage and amount; synced to databases for pipeline reporting and to ERPs at close.
Pipeline Synced with incremental and full sync per the Stacksync docs. Cases Support records; synced with help desk tools or internal databases for escalation workflows.
