Two-way sync
Changes in Nimble or Nutshell instantly reflect in both systems. No stale data, no manual imports.
Keep Nimble 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 Contacts, Companies, Deals, Tasks in Nimble with Notes, Products, Tags, Users 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.
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.
| Nimble objects | Nutshell objects | |
|---|---|---|
| Tasks To-do items tied to contacts, mirrored into work-management tools or reporting tables | Companies Account records that group people and leads for account-level syncs | |
| Activities Calls, events, and interaction history used for engagement reporting outside Nimble | Activities Logged calls, meetings, and emails used for engagement reporting | |
| Notes Free-text records attached to contacts, replicated for a complete account timeline | Tasks Rep to-dos mirrored into external work-management or reporting systems | |
| Tags Segmentation labels that map to list membership or filters in downstream systems | Notes Free-text history attached to leads and contacts, replicated for a full timeline | |
| Custom fields Account-defined contact attributes that carry enrichment or internal identifiers | Products Line items attached to leads, used to sync sold products into billing | |
| Contacts Person records with multi-value fields for email, phone, and social profiles; the primary sync entity | Tags Segmentation labels mapped to lists or filters in downstream tools |

Authenticate Nimble and Nutshell with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Nimble and Nutshell objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Nimble and Nutshell: authenticate both systems, choose the objects to sync (such as Nimble's Tasks and Activities), map fields visually, and changes propagate both ways in milliseconds — no code required.
On the Nimble side: Contacts, Companies, Deals, Tasks, plus custom fields where Nimble exposes them. On the Nutshell side: Notes, Products, Tags, Users. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for Nimble and Nutshell: Where both track pipeline: deal visibility across systems; Post-acquisition consolidation; Migration with a parallel run. Deal stage and value on shared accounts stay visible from either CRM.
Nimble: REST API (JSON). Authentication: API key; OAuth 2.0 available for registered applications. 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.
Nimble: Nimble auto-enriches contacts from social profiles and email signatures, so synced records can change without a user edit. 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 Nimble and Nutshell without custom code.
