Pros & Cons
IInfor LN
Pros
- Very strong project manufacturing and engineer-to-order support, with project budgeting, earned value management and progress billing tied directly into financials.
- Logistics transactions post automatically to the general ledger, and intercompany transactions are generated automatically across financial companies.

- PeerSpot reviewers rate stability and scalability highly, with deployments ranging from hundreds to thousands of users.
- Several reviewers find it more cost-effective than SAP for complex manufacturing.
Cons

- Reviewers find the interface unintuitive for occasional users, with navigation that takes many clicks.
- Configuring workflows, alerts and reports still needs technical skill, and implementations rely on experienced consultants.
