Two-way sync
Changes in Freshsales or Twenty CRM instantly reflect in both systems. No stale data, no manual imports.
Keep Freshsales and Twenty CRM in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Appointments, Notes, Sales activities, Products in Freshsales with Workspace Members, People, Companies, Opportunities 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.
Deal stage and value on shared accounts stay visible from either CRM.
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
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.
| Freshsales objects | Twenty CRM objects | |
|---|---|---|
| Notes Free-text records attached to contacts, accounts, and deals. | Opportunities Deal records tracked through pipeline stages, synced for forecasting. | |
| Sales activities Configurable activity types logged against records, useful for engagement scoring. | Tasks To-dos linked to people, companies, or deals. | |
| Products Catalog items attached to deals for line-level revenue data. | Notes Free-form notes attached to records, useful for mirroring activity from other tools. | |
| Contacts Person records carrying lifecycle stages; the main entity for two-way CRM syncs. | Custom Objects User-defined objects created in Twenty's data model settings, addressable through the same APIs as standard objects. | |
| Accounts Company records kept aligned with billing, ERP, and warehouse tables. | Attachments Files linked to records. | |
| Deals Pipeline records synced to a warehouse for revenue reporting. | Workspace Members User accounts used for record ownership and assignment mapping. |
