Why teams connect Azure Cosmos DB and Rillet

Work with Rillet's financial data straight from Azure Cosmos DB: 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 Partition keys, Change feed entries, Stored procedures and triggers, Databases in Azure Cosmos DB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Azure Cosmos DB, 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.
  • Sync CRM or ERP records into a Cosmos DB container that backs a customer-facing application.
  • Mirror Cosmos DB items into Postgres so teams can query operational data with standard SQL.

Internal tools without API plumbing

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

Write back safely

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

React to financial events

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

What you can sync between Azure Cosmos DB 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.

Azure Cosmos DB objects Rillet objects
Databases Top-level namespaces that scope containers and throughput provisioning. Invoice Payment Synced with incremental and full sync per the Stacksync docs.
Containers The unit of partitioning and throughput; each container maps to a synced collection. Charge Synced with incremental and full sync per the Stacksync docs.
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Reimbursement Synced with incremental and full sync per the Stacksync docs.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Custom Field Synced with incremental and full sync per the Stacksync docs.
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Account Synced with incremental and full sync per the Stacksync docs.
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Customer Synced with incremental and full sync per the Stacksync docs.
