Why teams connect DEAR Inventory and MotherDuck
Put DEAR Inventory's records in MotherDuck as live tables for reporting and analysis, without extract jobs, and write results back where DEAR Inventory can use them.
ERP data is some of the most asked-for data in the warehouse and some of the hardest to get: the record types are many, the APIs are strict, and extract jobs are brittle. Whether DEAR Inventory carries financials, operations, workforce data, or all three, the analysis belongs in MotherDuck next to everything else the company measures.
Stacksync syncs Assemblies / Production, Locations, Products, Stock levels from DEAR Inventory into tables in MotherDuck continuously, managing API limits and schema drift along the way. The connection is bi-directional, so values computed in MotherDuck can be written back to fields in DEAR Inventory where that is useful.
Common use cases
- 01 Sync modeled MotherDuck tables outward to operational tools for activation
- 02 Share curated, synced datasets with other teams through read-only database shares
- 03 Keep supplier and purchase order data aligned with the accounting system for accrual accuracy.
- 04 Sync stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.

How changes propagate between DEAR Inventory and MotherDuck
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
DEAR Inventory MotherDuck Sub-second propagation
DetectionDEAR Inventory notifies Stacksync of record changes through webhook events. Polling with modified-since filters.
DeliveryEach detected change is applied to MotherDuck as a row-level write, with types converted between the two schemas.
MotherDuck DEAR Inventory Interval-based propagation
DetectionStacksync polls MotherDuck for changes on an incremental schedule, reading only records changed since the previous pass. Polling.
DeliveryEach detected change is written to DEAR Inventory through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- DEAR Inventory: Subject to the platform's per-account API rate limits.
- MotherDuck: Subject to the platform's compute and concurrency limits rather than per-request API rate limits.
