Two-way sync
Changes in Copper CRM or Nutshell instantly reflect in both systems. No stale data, no manual imports.
Keep Copper CRM and Nutshell 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 Projects, Pipelines, Custom Field Definitions, People in Copper CRM with Tasks, Notes, Products, Tags in Nutshell 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.
When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
Deal stage and value on shared accounts stay visible from either CRM.
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.
| Copper CRM objects | Nutshell objects | |
|---|---|---|
| Pipelines Stage definitions that give opportunity records their stage context. | Users Rep records used to resolve ownership when syncing assignments | |
| Custom Field Definitions Org-defined fields whose definitions are fetched to build dynamic field mappings. | Leads Nutshell's deal object; synced as the pipeline record linked to people and companies | |
| People Individual contact records, often created from Gmail interactions, and the main target of contact syncs. | People Individual contacts, kept consistent with marketing and outreach tools | |
| Companies Organization records linked to people and opportunities. | Companies Account records that group people and leads for account-level syncs | |
| Leads Unqualified prospects kept separate from People until converted. | Activities Logged calls, meetings, and emails used for engagement reporting | |
| Opportunities Deals tracked through pipelines and stages; synced for revenue reporting. | Tasks Rep to-dos mirrored into external work-management or reporting systems |

Yes. Stacksync provides a managed, real-time two-way integration between Copper CRM and Nutshell: authenticate both systems, choose the objects to sync (such as Copper CRM's Pipelines and Custom Field Definitions), map fields visually, and changes propagate both ways in milliseconds — no code required.
Copper CRM: REST API. Authentication: API key paired with the requesting user's email address, sent as request headers. Nutshell: JSON-RPC API over HTTPS; a newer REST API is also offered. Authentication: HTTP Basic with account email and API key. Stacksync manages authentication, retries, and rate limits on both sides.
Copper CRM: Leads are a distinct object from People; conversion creates a person (and optionally a company and opportunity), so syncs must handle the conversion transition. Nutshell: The deal object is called a Lead in Nutshell, and it links to separate People and Company records rather than replacing them. Stacksync's field mapping accounts for these differences between Copper CRM and Nutshell without custom code.
