Why teams connect Cin7 and DuckDB

Give your engineers Cin7's data in DuckDB: read it with normal queries, write back through the sync, and skip the ERP API entirely.

ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.

Stacksync mirrors Sales orders, Purchase orders, Contacts, Branches / locations from Cin7 into DuckDB and keeps both sides consistent in real time. Whatever Cin7 is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in DuckDB sync back into Cin7 with its validations respected.

Common use cases

  • 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.
  • Consolidate stock movements from multiple branches into one reporting database.
  • Publish Cin7 inventory levels to storefronts, marketplaces, and a CRM so every channel quotes real availability.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Cin7 interface, limits, and retries.

React to ERP changes

Updates in Cin7 arrive as row changes in DuckDB, so jobs and triggers can respond as the business record changes.

Where Cin7 is the HR system of record: people data for internal systems

Worker and org records stay current in DuckDB for provisioning, access, and reporting systems that read from the database.

What you can sync between Cin7 and DuckDB

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.

Cin7 objects DuckDB objects
Sales orders Orders captured from all channels; the main object for fulfillment and revenue syncs. Attached databases Additional database files or external systems attached into one session for cross-source queries.
Purchase orders Supplier orders synced with procurement and accounting workflows. Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage.
Contacts Customers and suppliers, matched to CRM records to keep account data consistent. Schemas Namespaces within a database used to organize tables in sync outputs.
Branches / locations Warehouse entities that scope every stock movement and order allocation. Tables Columnar tables created via SQL; the destination for materialized sync data.
Stock adjustments and transfers Inventory movements read for audit and reconciliation reporting. Views SQL views used to shape or filter data for downstream consumers.
Credit notes / returns Return documents synced so finance and support see the same refund state. External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format.
