Why teams connect DEAR Inventory and Plex ERP

Two ERPs, one set of facts: Stacksync keeps DEAR Inventory and Plex ERP consistent in real time, whether they split the business or one is replacing the other.

Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.

Stacksync syncs Products, Stock levels, Sale orders, Purchase orders in DEAR Inventory with Suppliers, Shipments, Quality records, Parts in Plex ERP bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.

Common use cases

  • 01 Keep supplier and purchase order data aligned with the accounting system for accrual accuracy.
  • 02 Sync stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.
  • 03 Sync production and inventory data from Plex into a warehouse or Postgres for plant-level analytics.
  • 04 Keep customers, parts, and pricing aligned between Plex and the CRM the sales team uses.

Common sync patterns

Split by function

Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.

Two-tier roll-up

Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.

Migration in parallel

When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.

What you can sync between DEAR Inventory and Plex ERP

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
