Why teams connect Freshsales and HubSpot

Run Freshsales and HubSpot 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 Products, Contacts, Accounts, Deals in Freshsales with Product, Ticket, Quote, Goal in HubSpot 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

  • Push product-qualified leads from the warehouse into Freshsales as contacts with lifecycle stages set.
  • Keep Freshsales accounts aligned with a billing system so plan and revenue fields stay current.
  • Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.
  • Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or 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.
