Why teams connect DEAR Inventory and Klaviyo
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Klaviyo and DEAR Inventory.
The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Klaviyo 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Metrics, Campaigns, Flows, Templates in Klaviyo with Products, Stock levels, Sale orders, Purchase orders 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
- Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
- Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
- 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.
