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

Yes. Stacksync provides a managed, real-time two-way integration between DEAR Inventory and Insightly: authenticate both systems, choose the objects to sync (such as DEAR Inventory's Assemblies / Production and Locations), 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 Insightly: Polling on record updated-date fields. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.

On the Insightly side: Products, Custom Fields, Contacts, Organizations, plus custom fields where Insightly exposes them. On the DEAR Inventory side: Stock levels, Sale orders, Purchase orders, Customers. 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.

Common patterns for DEAR Inventory and Insightly: One customer master; Where DEAR Inventory manages people and org data: keep Insightly aligned; Where DEAR Inventory handles order-to-cash: closed-won flows through.
