Why teams connect Infor LN and Plex ERP
Two ERPs, one set of facts: Stacksync keeps Infor LN 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 Projects, Service orders, Items, Bills of material in Infor LN 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 Replicate LN data into a warehouse for production, OTIF, and supply chain reporting.
- 02 Run a two-way sync of business partners between LN and a CRM so sales and manufacturing share account data.
- 03 Keep customers, parts, and pricing aligned between Plex and the CRM the sales team uses.
- 04 Push sales orders captured in e-commerce or EDI systems into Plex for scheduling and fulfillment.
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.
What you can sync between Infor LN 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.
| Infor LN objects | Plex ERP objects | How this pairing syncs | |
|---|---|---|---|
| Sales orders Demand documents synced in from EDI and commerce channels. | Sales orders Demand records written in from e-commerce or EDI channels and read out for fulfillment status | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Purchase orders Supply documents shared with supplier and procurement systems. | Purchase orders Procurement records mirrored to accounting and planning systems | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Production orders Shop-floor work orders synced with MES for execution visibility. | Inventory On-hand balances and locations replicated for visibility outside the plant system | Production orders is specific to Infor LN and Inventory to Plex ERP — each maps to any object or custom field on the other side. | |
| Warehouse / inventory Stock positions exposed so external channels reflect real availability. | Production jobs Shop-floor work records combining ERP and MES data for output reporting | Warehouse / inventory is specific to Infor LN and Production jobs to Plex ERP — each maps to any object or custom field on the other side. | |
| Projects Project structures used in engineer-to-order manufacturing scenarios. | Customers Account records kept consistent with the sales team's CRM | Projects is specific to Infor LN and Customers to Plex ERP — each maps to any object or custom field on the other side. | |
| Service orders Aftermarket service documents synced with field service tools. | Suppliers Vendor records aligned with procurement and AP tools | Service orders is specific to Infor LN and Suppliers to Plex ERP — each maps to any object or custom field on the other side. |
How changes propagate between Infor LN and Plex ERP
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Infor LN Plex ERP Interval-based propagation
DetectionStacksync polls Infor LN for changes on an incremental schedule, reading only records changed since the previous pass. Event-style BOD publications through Infor ION where configured.
DeliveryEach detected change is written to Plex ERP through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations
- Infor LN: Subject to the ION API gateway's tenant rate limits in cloud deployments.
- Plex ERP: Subject to the platform's API rate limits.

-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Infor LN and Plex ERP records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Infor LN and Plex ERP connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Infor LN–Plex ERP integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Infor LN and Plex ERP. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Infor LN: Event-style BOD publications through Infor ION where configured; otherwise polling. On Plex ERP: Polling; no general-purpose change webhooks. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Infor LN side: Projects, Service orders, Items, Bills of material, plus custom fields where Infor LN exposes them. On the Plex ERP side: Suppliers, Shipments, Quality records, Parts. Stacksync auto-detects both schemas and converts types between the two systems.
