Why teams connect DEAR Inventory and Resend
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Resend and DEAR Inventory.
The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Resend is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.
Stacksync syncs Audiences, Broadcasts, Domains, Email events in Resend with Stock adjustments and transfers, Assemblies / Production, Locations, Products in DEAR Inventory bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.
Common use cases
- Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
- Trigger transactional sends when a row changes in an operational database, such as an order status update.
- Land orders, costs, and inventory movements in a warehouse for margin and stock-turn reporting.
- Keep supplier and purchase order data aligned with the accounting system for accrual accuracy.
