Why teams connect Infor M3 and Plex ERP

Two ERPs, one set of facts: Stacksync keeps Infor M3 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 Purchase Orders, Manufacturing Orders, Inventory Balances, Invoices in Infor M3 with Production jobs, Sales orders, Purchase orders, Customers 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

  • Feed manufacturing order status to a customer portal for order tracking in fashion, food, or equipment supply chains
  • Keep supplier and purchase order data aligned between M3 and procurement tools
  • Mirror purchase orders and receipts to accounting or planning tools.
  • Feed quality and scrap data to dashboards supervisors check without logging into Plex.

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.

Shared master data

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