Why teams connect PostgreSQL and Rillet

Work with Rillet'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 Credit Memo, Bill, Journal Entry, Invoice Payment from Rillet into Custom Types and Enums, Tables, Views, Materialized Views 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 Rillet with validation, so the finance system stays the system of record.

Common use cases

  • Mirror journal entries and contract revenue data into a warehouse for board and ARR reporting.
  • Push billing events from a product or usage-metering system into Rillet for revenue recognition.
  • Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
  • Let an application write to its own database and have those rows appear as records in business systems in near real time

Internal tools without API plumbing

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

Write back safely

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

React to financial events

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

What you can sync between PostgreSQL and Rillet

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.

PostgreSQL objects Rillet objects
JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata. Invoice Payment Synced with incremental and full sync per the Stacksync docs.
Sequences Generate surrogate keys for rows created by inbound syncs. Charge Synced with incremental and full sync per the Stacksync docs.
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. Reimbursement Synced with incremental and full sync per the Stacksync docs.
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. Custom Field Synced with incremental and full sync per the Stacksync docs.
Views Read-side projections used to expose joined or filtered data to a sync. Account Synced with incremental and full sync per the Stacksync docs.
Materialized Views Precomputed result sets synced outward on a refresh schedule. Customer Synced with incremental and full sync per the Stacksync docs.

How the PostgreSQL and Rillet connectors work

PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL frontend/backend protocol)
Authentication
Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user
Change detection
Logical replication (wal_level = logical) for change data capture via the "Postgres" connector; database triggers (TRIGGER grant + stacksync_logging schema) via the trigger-based "Postgres Heroku" connector where
Capabilities

Rillet

Integration surface
REST API (OpenAPI-specified, with production and sandbox environments)
Authentication
API key generated in Rillet (Organization Setting -> API Access); uncheck Read Only for bidirectional sync, check Read Only for one-way sync
