Two-way sync
Changes in Kommo or Nutshell instantly reflect in both systems. No stale data, no manual imports.
Keep Kommo 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 Leads, Contacts, Companies, Pipelines & Statuses in Kommo 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.
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.
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
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.
| Kommo objects | Nutshell objects | |
|---|---|---|
| Contacts Person records sync with other CRMs and databases for a shared contact file. | Leads Nutshell's deal object; synced as the pipeline record linked to people and companies | |
| Companies Organization records map to accounts in ERPs and invoicing tools. | People Individual contacts, kept consistent with marketing and outreach tools | |
| Pipelines & Statuses Stage definitions structure lead progress and drive stage-change syncs to reporting tools. | Companies Account records that group people and leads for account-level syncs | |
| Tasks Follow-up records keep rep activity consistent across systems. | Activities Logged calls, meetings, and emails used for engagement reporting | |
| Notes Free-text and system notes attach context to synced leads and contacts. | Tasks Rep to-dos mirrored into external work-management or reporting systems | |
| Custom Fields Per-entity custom fields hold data written from external databases and enrichment. | Notes Free-text history attached to leads and contacts, replicated for a full timeline |

Yes. Stacksync provides a managed, real-time two-way integration between Kommo and Nutshell: authenticate both systems, choose the objects to sync (such as Kommo's Contacts and Companies), map fields visually, and changes propagate both ways in milliseconds — no code required.
Kommo: The API uses OAuth 2.0 with short-lived access tokens refreshed via refresh tokens, and supports webhooks on record lifecycle events. Nutshell: Nutshell's most full-featured API is JSON-RPC: each call names a method such as findLeads or editLead instead of hitting resource URLs, though a newer REST API is also available. Stacksync's field mapping accounts for these differences between Kommo and Nutshell without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Kommo and Nutshell records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Kommo and Nutshell connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Kommo–Nutshell integration in-house.
Yes — Stacksync ships production-grade connectors for both Kommo and Nutshell. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Kommo: Webhooks on record add and update events, plus polling for backfill. On Nutshell: Webhook subscriptions for record events, with polling as fallback. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
