Why teams connect DuckDB and Sage 300

Give your engineers Sage 300'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 AR Invoices and Receipts, AR Customers, AP Vendors, GL Accounts from Sage 300 into DuckDB and keeps both sides consistent in real time. Whatever Sage 300 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 Sage 300 with its validations respected.

Common use cases

  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.
  • Push aggregates computed in DuckDB out to a CRM or business tools so analysis results reach operational systems.
  • Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
  • Sync AR customers, invoices, and balances into a CRM for multi-currency account visibility.

Where Sage 300 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.

Controlled write-back

Choose exactly which tables and fields may flow from DuckDB back into Sage 300, keeping the ERP authoritative.

Read ERP records with a query

Records from Sage 300 live in DuckDB as ordinary tables or collections, joinable with the rest of your data.

What you can sync between DuckDB and Sage 300

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 Sage 300 objects
Schemas Namespaces within a database used to organize tables in sync outputs. Purchase Orders Procurement documents read for spend visibility and receiving.
Tables Columnar tables created via SQL; the destination for materialized sync data. Inventory Items Item master with costing and quantities, synced to storefronts and WMS.
Views SQL views used to shape or filter data for downstream consumers. AR Invoices and Receipts Billing and payment records replicated for cash and revenue reporting.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. AR Customers Receivables customer master synced to CRMs and billing tools.
Attached databases Additional database files or external systems attached into one session for cross-source queries. AP Vendors Payables vendor master synced with procurement and payment systems.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. GL Accounts Chart of accounts read for transaction mapping across integrations.
