Why teams connect Azure SQL Database and Kustomer

Treat Kustomer like part of your database: its records live in Azure SQL Database 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 Azure SQL Database, where it can be queried and joined like everything else.

Stacksync mirrors Customers, Conversations, Messages, Companies from Kustomer into Schemas, Rows and columns, Stored procedures, Change tracking / CDC tables in Azure SQL Database with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Kustomer 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

  • Escalate conversation-derived signals into the CRM as tasks or opportunities
  • Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
  • Feed an Azure SQL operational database with orders and inventory from an ERP in near real time.
  • Expose SaaS data (billing, support tickets) as tables in Azure SQL for reporting teams already on Microsoft tooling.

Trigger workflows from CRM changes

Field and stage updates in Kustomer arrive as row changes in Azure SQL Database, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Kustomer become tables in Azure SQL Database you can join with application data directly.

Product events onto CRM records

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

What you can sync between Azure SQL Database and Kustomer

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.

Azure SQL Database objects Kustomer objects
Rows and columns Standard relational records with typed columns; primary keys anchor upserts. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline.
Stored procedures Existing business logic that some teams invoke on write instead of direct table inserts. Users Agent records map conversation ownership to people in other systems.
Change tracking / CDC tables System-maintained change records used to drive incremental sync. Teams Team assignments support routing parity and reporting.
Tables The primary sync target; rows map one-to-one to records in the paired system. Tags Labels on conversations and customers sync for categorization and analytics.
Views Read-only projections used when the sync should expose a curated shape rather than raw tables. Notes Internal annotations carry context alongside synced conversations.
Schemas Namespaces that organize tables and control which objects a sync user can reach. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it.
