Why teams connect DEAR Inventory and DuckDB

Give your engineers DEAR Inventory'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 Products, Stock levels, Sale orders, Purchase orders from DEAR Inventory into DuckDB and keeps both sides consistent in real time. Whatever DEAR Inventory 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 DEAR Inventory 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.
  • Push sale orders from a storefront or CRM into DEAR for fulfillment without manual re-entry.
  • Land orders, costs, and inventory movements in a warehouse for margin and stock-turn reporting.

Read ERP records with a query

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

Internal tools and automations without API code

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

React to ERP changes

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