Why teams connect DEAR Inventory and Lemlist
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Lemlist and DEAR Inventory.
The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Lemlist 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Team Members, Campaigns, Leads, Activities in Lemlist with Assemblies / Production, Locations, Products, Stock levels 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
- Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
- Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
- Sync stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.
- Push sale orders from a storefront or CRM into DEAR for fulfillment without manual re-entry.
Master data corrections travel
A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.
