How Infor Small Parcel Shipping (SPS) connects to Infor LN
Native module of Infor WMS
SPS lives inside Infor WMS rather than inside the ERP. Orders and shipments originate in the ERP (LN here, though M3 and CloudSuite are also named), flow to WMS for picking and packing, and the parcel step then runs inside WMS.
ERP to WMS integration layer
Orders, items and shipment confirmations pass between the ERP and WMS through the integration your Infor deployment uses, commonly ION messaging. The exact documents differ by ERP, so check the LN-specific WMS integration guide.
What data moves
| From | To | Data | When |
|---|---|---|---|
| Infor LN | Infor WMS | Sales or transfer orders, items, ship-to addresses | Order release to the warehouse |
| Infor WMS | Carrier services | Package weight, dimensions, service level and addresses for rating | Pack or ship step in WMS |
| Carrier services | Infor WMS | Rate, tracking number and label | Shipment is rated or manifested |
| Infor WMS | Infor LN | Shipment confirmation with tracking numbers and freight cost | Shipment closed in WMS |
Setting it up
- 1Confirm WMS and ERP versionsCheck the Infor WMS release and the LN integration documentation for the parcel features you need.
- 2Set up carrier accountsConfigure UPS, FedEx and USPS accounts and credentials, and decide which services are allowed per customer or order type.
- 3Maintain item dimensions and weightsRating depends on accurate weights and dimensions, so load or clean them before go-live.
- 4Configure packing and label printersSet up thermal printers and label formats for carrier compliance, and test each carrier's label at the pack station.
- 5Configure LTL rating if neededFor US and Canada LTL, set up the rate tables or carriers according to the Infor documentation.
- 6Test end to endShip test orders from LN release through manifest to confirmation, and check tracking numbers return to the ERP.
What usually breaks
- !Missing or wrong item weights and dimensions cause under-rated parcels and carrier adjustments after the fact.
- !Address validation errors surface at the pack station when they should have been caught at order entry.
- !Carrier credentials or account numbers that expire stop all label printing at once.
- !Shipment confirmation that does not return freight cost to the ERP leaves landed cost and billing incomplete.
- !Label stock and printer settings differ between carriers, and a generic template produces unscannable labels.
A private AI layer across both systems
Shipping exception triage
A private assistant reads failed rates, address errors and unconfirmed shipments across WMS and LN, groups them by cause and drafts the fix for approval.
Freight cost reconciliation
It compares carrier invoices with the freight recorded in LN and explains differences caused by weight corrections or accessorials.
Plain-language shipment questions
Customer service asks where an order is and which tracking number applies, with the data read from both systems on your own servers.

Ten questions to score whether your warehouse is ready for a WMS, or whether ERP inventory control and process fixes come first.
When something else fits better
- A standalone multi-carrier shipping product may be simpler if your volume is low or WMS is not in scope.
- If you use a 3PL, their carrier tooling may make a native parcel module unnecessary.
- Carrier web portals work for very low shipment counts but do not return data to the ERP.
Frequently asked questions
Is SPS part of Infor LN?
No, it is a native module of Infor WMS, which Infor documents alongside LN, M3 and CloudSuite. You need Infor WMS in the picture, and the LN to WMS integration carries the orders and confirmations.
Which carriers does it support?
Infor documents rating and labels for UPS, FedEx and USPS, plus configured LTL rating for US and Canada shipments. Check the current WMS release documentation for the exact services supported.
What can AI add around shipping?
Exception triage, freight reconciliation and plain-language status questions across WMS and the ERP. It reads data read-only on your infrastructure, and any correction to an order or shipment goes through a person.
