Why teams connect Nutshell and SQL Server

Treat Nutshell like part of your database: its records live in SQL Server as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in SQL Server, where it can be queried and joined like everything else.

Stacksync mirrors Companies, Activities, Tasks, Notes from Nutshell into Tables, Views, Columns, Primary and Unique Keys in SQL Server with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Nutshell with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • Keep People and Companies consistent between Nutshell and email marketing or outreach tools.
  • Write subscription or product data from internal systems into Nutshell so reps see account context.
  • Expose SaaS records as SQL Server tables that existing SSRS reports and internal apps can query
  • Mirror on-premises ERP data held in SQL Server into cloud CRM and support systems

Product events onto CRM records

Signup, usage, or lifecycle changes written to SQL Server sync onto the matching records in Nutshell, giving go-to-market teams live product context.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Nutshell API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Nutshell arrive as row changes in SQL Server, ready to drive jobs and notifications.

What you can sync between Nutshell and SQL Server

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.

Nutshell objects SQL Server objects
Tags Segmentation labels mapped to lists or filters in downstream tools Primary and Unique Keys Match keys for idempotent upserts and conflict handling.
Users Rep records used to resolve ownership when syncing assignments CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers.
Leads Nutshell's deal object; synced as the pipeline record linked to people and companies Stored Procedures T-SQL logic that can validate or post-process synced rows.
People Individual contacts, kept consistent with marketing and outreach tools Databases Instance-level databases that scope a sync's reads and writes.
Companies Account records that group people and leads for account-level syncs Schemas Namespaces (dbo and custom) used to organize synced tables.
Activities Logged calls, meetings, and emails used for engagement reporting Tables The primary sync target; rows map to records in connected systems.
