DEAR Inventory to Twenty CRM integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between DEAR Inventory and Twenty CRM: authenticate both systems, choose the objects to sync (such as DEAR Inventory's Sale orders and Purchase orders), map fields visually, and changes propagate both ways in milliseconds — no code required.

Change detection on DEAR Inventory: Polling with modified-since filters; webhook notifications for sale and purchase events are available on subscriptions that include the Automation module. On Twenty CRM: Webhooks on record create, update, and delete events, or polling on record update timestamps. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.

On the Twenty CRM side: Tasks, Notes, Custom Objects, Attachments, plus custom fields where Twenty CRM exposes them. On the DEAR Inventory side: Locations, Products, Stock levels, Sale orders. Stacksync auto-detects both schemas and converts types between the two systems.

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
