Why teams connect Close and Supabase

Treat Close like part of your database: its records live in Supabase 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 Supabase, where it can be queried and joined like everything else.

Stacksync mirrors Custom Fields, Users, Smart Views, Leads from Close into Storage Object Metadata, Tables, Views, Schemas in Supabase with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Close 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

  • Write product usage or firmographic data from an internal database onto Close lead custom fields to prioritize follow-up.
  • Sync Close leads and opportunities into Postgres or a warehouse for pipeline reporting outside Close's built-in reports.
  • Reflect auth.users state into support and CRM systems so teams see account status without querying the database
  • Push product events captured in Supabase Postgres to marketing tools for lifecycle campaigns

Trigger workflows from CRM changes

Field and stage updates in Close arrive as row changes in Supabase, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Close become tables in Supabase you can join with application data directly.

Product events onto CRM records

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

What you can sync between Close and Supabase

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.

Close objects Supabase objects
Contacts People nested under a lead, with emails and phone numbers used for outreach syncs. Row Level Security Policies Row-level access rules that govern what the REST layer exposes.
Opportunities Deal records with value, confidence, and status; commonly synced to reporting and billing systems. JSONB Columns Semi-structured payloads such as event properties or nested objects.
Activities Calls, emails, SMS, notes, and meetings logged against a lead; the source for engagement analytics. Database Functions Postgres functions that can transform or validate synced rows.
Tasks Follow-up items assigned to users; synced for workload and SLA reporting. Storage Object Metadata File metadata rows that can be joined to synced application data.
Custom Activities User-defined activity types with their own custom fields, mapped like standard activities. Tables Standard Postgres tables; the primary two-way sync target.
Custom Fields Org-specific fields on leads, contacts, and opportunities; addressed by stable field ids in syncs. Views Read-side projections exposed to outbound syncs.
