Why teams connect AWS S3 and Rillet

Land the financial records from Rillet in AWS S3 continuously, and write results back, without building or maintaining a pipeline.

Finance data belongs in the warehouse: revenue, invoices, payments, and customers joined with everything else the business measures. Getting it there usually means an extraction pipeline that breaks quietly and delivers yesterday's numbers.

Stacksync syncs Invoice Payment, Charge, Reimbursement, Custom Field from Rillet into tables in AWS S3 in real time, and the connection works in both directions: values computed in AWS S3 can be written back to fields in Rillet where you want them operational. Schema changes are handled, API limits are managed, and the sync is something you configure rather than code you maintain.

Common use cases

  • Push billing events from a product or usage-metering system into Rillet for revenue recognition.
  • Sync AR and collection status back to customer success tools ahead of renewals.
  • Trigger incremental sync runs from S3 event notifications when new files land in a prefix.
  • Stage bulk loads for warehouses that ingest from object storage.

Queryable history for audit and reconciliation

A continuously synced copy in AWS S3 gives you a durable, queryable record of financial data for month-end and audit questions.

Finance analytics without ETL

Invoices, payments, and customer records from Rillet arrive in AWS S3 as queryable tables, current within seconds instead of a day behind.

Revenue joined with everything else

Analysts combine Rillet's financial records with product, marketing, or operational data already in AWS S3 for reporting the finance system cannot do alone.

How the AWS S3 and Rillet connectors work

AWS S3

Integration surface
REST API (the S3 API), accessed directly or through AWS SDKs
Authentication
AWS IAM credentials with SigV4 signing; commonly a role scoped to specific buckets and prefixes
Change detection
S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge; list-based polling as a fallback
Capabilities
read · write · webhooks
Rate limits
Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes

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.
