Why teams connect Hyperline and PostgreSQL

Work with Hyperline's financial data straight from PostgreSQL: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Payments, Billable events, Credit notes, Customers from Hyperline into Views, Materialized Views, Schemas, Columns in PostgreSQL and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against PostgreSQL, and rows your code writes or updates flow back into Hyperline with validation, so the finance system stays the system of record.

Common use cases

  • Sync Hyperline customers and subscription status into a CRM so sales and success teams see billing state on the account record.
  • Push metered usage events from a product database into Hyperline to drive usage-based invoicing.
  • Let an application write to its own database and have those rows appear as records in business systems in near real time
  • Consolidate data from several microservice databases into one operational Postgres store

Internal tools without API plumbing

Build dashboards and back-office tools directly on PostgreSQL; Stacksync handles the API calls, rate limits, and retries against Hyperline.

Write back safely

Updates written to the synced tables in PostgreSQL propagate into Hyperline, so automations can create or correct finance records without custom integration code.

React to financial events

Changes in Hyperline appear in PostgreSQL as row changes, so you can trigger downstream logic with the database tooling you already use.

What you can sync between Hyperline and PostgreSQL

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.

Hyperline objects PostgreSQL objects
Credit notes Adjustments and refunds synced for accurate revenue reporting. Views Read-side projections used to expose joined or filtered data to a sync.
Customers Billing accounts that syncs match against CRM and product records. Materialized Views Precomputed result sets synced outward on a refresh schedule.
Subscriptions Active plans and their lifecycle state, synced to show billing status elsewhere. Schemas Namespaces that scope which tables a sync reads and writes.
Products / prices The catalog of products and price configurations referenced by subscriptions. Columns Field-level mapping targets; types are mapped to the connected system's field types.
Invoices Issued billing documents synced into accounting and reporting systems. Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution.
Payments Settlement records used to reconcile revenue against invoices. JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata.
