Why teams connect DuckDB and Hyperline

Work with Hyperline's financial data straight from DuckDB: 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 Payments, Billable events, Credit notes, Customers from Hyperline into Schemas, Tables, Views, External files (Parquet/CSV/JSON) in DuckDB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against DuckDB, and rows your code writes or updates flow back into Hyperline with validation, so the finance system stays the system of record.

Common use cases

  • Push metered usage events from a product database into Hyperline to drive usage-based invoicing.
  • Sync invoices and payments into a data warehouse or accounting system for revenue reporting and reconciliation.
  • Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.

Write back safely

Updates written to the synced tables in DuckDB propagate into Hyperline, so automations can create or correct finance records without custom integration code.

React to financial events

Changes in Hyperline appear in DuckDB 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 Hyperline live in DuckDB as regular tables or collections your team can join, index, and query.

What you can sync between DuckDB and Hyperline

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.

DuckDB objects Hyperline objects
Views SQL views used to shape or filter data for downstream consumers. Credit notes Adjustments and refunds synced for accurate revenue reporting.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Customers Billing accounts that syncs match against CRM and product records.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Subscriptions Active plans and their lifecycle state, synced to show billing status elsewhere.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Products / prices The catalog of products and price configurations referenced by subscriptions.
Schemas Namespaces within a database used to organize tables in sync outputs. Invoices Issued billing documents synced into accounting and reporting systems.
Tables Columnar tables created via SQL; the destination for materialized sync data. Payments Settlement records used to reconcile revenue against invoices.
