Why teams connect Acumatica and Plex ERP

Two ERPs, one set of facts: Stacksync keeps Acumatica 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 Opportunities and Cases, Customers, Vendors, Sales Orders in Acumatica with Shipments, Quality records, Parts, Inventory 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 Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.
  • 02 Mirror stock items and quantities to external channels so availability stays accurate across systems.
  • 03 Feed quality and scrap data to dashboards supervisors check without logging into Plex.
  • 04 Sync production and inventory data from Plex into a warehouse or Postgres for plant-level analytics.

Common sync patterns

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

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.
