Why teams connect Postgres Heroku and Rillet

Work with Rillet's financial data straight from Postgres Heroku: 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 Sequences, Follower Databases, Tables, Views in Postgres Heroku and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Postgres Heroku, 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

  • Keep customers and invoices aligned between Rillet and a CRM so finance and sales work from the same account records.
  • Mirror journal entries and contract revenue data into a warehouse for board and ARR reporting.
  • Expose CRM objects as Postgres tables the Heroku application can query and join directly
  • Sync Heroku Postgres into a warehouse for reporting without running ETL dynos

React to financial events

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

Query finance data like any other data

Customers, invoices, and payments from Rillet live in Postgres Heroku as regular tables or collections your team can join, index, and query.

Internal tools without API plumbing

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

What you can sync between Postgres Heroku 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.

Tables Standard Postgres tables; the primary two-way sync target for app data. Customer Synced with incremental and full sync per the Stacksync docs.
Views Read-side projections exposed to outbound syncs. Vendor Synced with incremental and full sync per the Stacksync docs.
Materialized Views Precomputed result sets synced outward on refresh. Invoice Synced with incremental and full sync per the Stacksync docs.
Schemas Namespaces that scope which tables a sync reads and writes. Credit Memo Synced with incremental and full sync per the Stacksync docs.
Primary and Unique Keys Match keys for idempotent upserts from connected systems. Bill Synced with incremental and full sync per the Stacksync docs.

How the Postgres Heroku and Rillet connectors work

Postgres Heroku

Integration surface
SQL wire protocol (standard PostgreSQL)
Authentication
Database credentials from the Heroku DATABASE_URL config var; SSL required
Change detection
Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings
Capabilities
read · write
Rate limits
No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan

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
Change detection
Near real-time updates via change tracking; incremental sync per object, with delete detection (some objects checked every 1h or 4h)
Capabilities
read · write · CDC · webhooks
Rate limits
Subject to the platform's API rate limits.
