Why teams connect Freshsales and Outreach

Run Freshsales and Outreach 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 Notes, Sales activities, Products, Contacts in Freshsales with Sequence states, Mailings, Calls, Tasks in Outreach 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 Sync sales activities and appointments into analytics tools for rep productivity reporting.
  • 02 Two-way sync of contacts and accounts between Freshsales and a Postgres database so product and data teams query CRM data with SQL.
  • 03 Suppress prospects across systems when a contact unsubscribes or a customer churns.
  • 04 Enroll leads in sequences automatically by writing sequence-state records when a lead crosses a scoring threshold in the warehouse.

Common sync patterns

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.
