Why teams connect SQL Server and Twenty CRM

Treat Twenty CRM 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 People, Companies, Opportunities, Tasks from Twenty CRM into Columns, Primary and Unique Keys, CDC Change Tables, Stored Procedures in SQL Server with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Twenty CRM 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

  • Two-way sync of People and Companies between Twenty and a production Postgres database so engineers can query CRM data with SQL.
  • Push product usage or billing data from a warehouse into Twenty custom fields to give reps account context.
  • Bi-directional sync between SQL Server rows and CRM objects so .NET line-of-business apps and sales tools share one dataset
  • Expose SaaS records as SQL Server tables that existing SSRS reports and internal apps can query

Internal tools without API code

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

Trigger workflows from CRM changes

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

Query the CRM like a database

Accounts, contacts, and custom objects from Twenty CRM become tables in SQL Server you can join with application data directly.

What you can sync between SQL Server and Twenty 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.

SQL Server objects Twenty CRM objects
Schemas Namespaces (dbo and custom) used to organize synced tables. People Individual contact records with emails, phones, and company links; a core target for contact syncs.
Tables The primary sync target; rows map to records in connected systems. Companies Account-level records that group people and opportunities.
Views Read-side projections used as outbound sync sources. Opportunities Deal records tracked through pipeline stages, synced for forecasting.
Columns Field-level mapping targets with T-SQL types. Tasks To-dos linked to people, companies, or deals.
Primary and Unique Keys Match keys for idempotent upserts and conflict handling. Notes Free-form notes attached to records, useful for mirroring activity from other tools.
CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers. Custom Objects User-defined objects created in Twenty's data model settings, addressable through the same APIs as standard objects.
