Why teams connect ClickHouse and Rillet

Land the financial records from Rillet in ClickHouse 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 Credit Memo, Bill, Journal Entry, Invoice Payment from Rillet into tables in ClickHouse in real time, and the connection works in both directions: values computed in ClickHouse 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

  • 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.
  • Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.

Finance analytics without ETL

Invoices, payments, and customer records from Rillet arrive in ClickHouse 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 ClickHouse for reporting the finance system cannot do alone.

Write-back of computed fields

Scores or segments computed in ClickHouse, like payment-risk flags or customer tiers, sync back onto records in Rillet where the finance team can act on them.
