Why teams connect Kommo and SQL Server

Treat Kommo 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 Pipelines & Statuses, Tasks, Notes, Custom Fields from Kommo into Primary and Unique Keys, CDC Change Tables, Stored Procedures, Databases in SQL Server with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Kommo 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

  • Replicate Kommo leads and contacts into a database or warehouse for reporting beyond built-in dashboards
  • Push web form and product signups into Kommo pipelines as they are submitted so messenger-based follow-up starts quickly
  • 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 Kommo API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Kommo 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 Kommo become tables in SQL Server you can join with application data directly.

What you can sync between Kommo 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.

Kommo objects SQL Server objects
Custom Fields Per-entity custom fields hold data written from external databases and enrichment. Stored Procedures T-SQL logic that can validate or post-process synced rows.
Users Account users map lead ownership to people in other systems. Databases Instance-level databases that scope a sync's reads and writes.
Chats Messenger conversations from WhatsApp, Instagram, and other channels attach to leads and contacts. Schemas Namespaces (dbo and custom) used to organize synced tables.
Leads The central pipeline record; external signups and form fills sync in as leads. Tables The primary sync target; rows map to records in connected systems.
Contacts Person records sync with other CRMs and databases for a shared contact file. Views Read-side projections used as outbound sync sources.
Companies Organization records map to accounts in ERPs and invoicing tools. Columns Field-level mapping targets with T-SQL types.
