Why teams connect IBM AS/400 and Rillet

Work with Rillet's financial data straight from IBM AS/400: 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 Account, Customer, Vendor, Invoice from Rillet into Physical files (tables), Logical files (views), Members, Rows / records in IBM AS/400 and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against IBM AS/400, 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.
  • Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.

Query finance data like any other data

Customers, invoices, and payments from Rillet live in IBM AS/400 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 IBM AS/400; Stacksync handles the API calls, rate limits, and retries against Rillet.

Write back safely

Updates written to the synced tables in IBM AS/400 propagate into Rillet, so automations can create or correct finance records without custom integration code.

What you can sync between IBM AS/400 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.

IBM AS/400 objects Rillet objects
Libraries The schema-equivalent containers that scope which files a sync reads. Account Synced with incremental and full sync per the Stacksync docs.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Customer Synced with incremental and full sync per the Stacksync docs.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Vendor Synced with incremental and full sync per the Stacksync docs.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Invoice Synced with incremental and full sync per the Stacksync docs.
Rows / records The unit of read and write, accessed via SQL or record-level access. Credit Memo Synced with incremental and full sync per the Stacksync docs.
Journals and journal receivers The change log that enables log-based CDC on journaled files. Bill Synced with incremental and full sync per the Stacksync docs.

How the IBM AS/400 and Rillet connectors work

IBM AS/400

Integration surface
SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access
Authentication
IBM i user profile credentials (database credentials)
Change detection
Journal-based CDC by reading journal receivers on journaled files; polling as a fallback
Capabilities
read · write · CDC
Rate limits
Bounded by system resources and subsystem configuration rather than an API quota.

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.
