Why teams connect Infor LN and Infor M3
Two ERPs, one set of facts: Stacksync keeps Infor LN and Infor M3 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 Sales orders, Purchase orders, Production orders, Warehouse / inventory in Infor LN with Purchase Orders, Manufacturing Orders, Inventory Balances, Invoices in Infor M3 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
- Replicate LN data into a warehouse for production, OTIF, and supply chain reporting.
- Run a two-way sync of business partners between LN and a CRM so sales and manufacturing share account data.
- Keep supplier and purchase order data aligned between M3 and procurement tools
- Consolidate M3 transactional data into an analytics database for cross-plant reporting
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 Infor M3
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 | Infor M3 objects | |
|---|---|---|
| Business partners LN's unified customer/supplier records matched against CRM accounts. | Items Item master records provide the SKU, unit, and attribute data other systems price and sell against. | |
| Sales orders Demand documents synced in from EDI and commerce channels. | Customers Customer master records sync with CRM account records to keep one shared customer file. | |
| Purchase orders Supply documents shared with supplier and procurement systems. | Suppliers Supplier records align procurement tools with the vendors M3 purchases from. | |
| Production orders Shop-floor work orders synced with MES for execution visibility. | Customer Orders Orders created in commerce or CRM systems land in M3 for fulfillment and invoicing. | |
| Warehouse / inventory Stock positions exposed so external channels reflect real availability. | Purchase Orders PO headers and lines sync outward so buyers and receiving teams see the same demand. | |
| Projects Project structures used in engineer-to-order manufacturing scenarios. | Manufacturing Orders Production order status feeds portals and CRMs so promised dates reflect the shop floor. |

FAQ
Infor LN and Infor M3 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Infor LN and Infor M3: authenticate both systems, choose the objects to sync (such as Infor LN's Business partners and Sales orders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Infor LN and Infor M3: Shared master data; Split by function; Two-tier roll-up. Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.
-
Infor LN: SOAP and REST web services, with standardized BOD exchange through Infor ION in Infor OS deployments. Authentication: OAuth 2.0 via the ION API gateway in cloud deployments; application credentials on premises. Infor M3: REST API (M3 API programs exposed through the Infor ION API gateway). Authentication: OAuth 2.0 via Infor OS / ION API authorization. Stacksync manages authentication, retries, and rate limits on both sides.
-
Infor LN: Its canonical integration path is standardized Business Object Documents (BODs) published and consumed through Infor ION. Infor M3: Infor ION can publish standard Business Object Documents (for example sales orders and item master changes) as events for downstream consumers, giving an event-based alternative to polling once configured in ION. Stacksync's field mapping accounts for these differences between Infor LN and Infor M3 without custom code.
-
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 Infor M3 records are not retained after a sync operation.
