What Aerospace & Defense Companies Need From an ERP
Aerospace and defence manufacturers must satisfy AS9100 and ITAR/EAR compliance while managing long-lifecycle programmes that span decades. ERP for this sector requires project-based manufacturing with earned value management (EVMS), configuration management, and full material traceability. Contract accounting under CAS and FAR regulations demands specialised cost accumulation and billing. Multi-level bills of material with effectivity dating support engineering changes across product revisions. MRO operations need to track component life limits, airworthiness directives, and service bulletins throughout the entire fleet lifecycle.
Verdict: IFS Applications is the stronger choice for Aerospace & Defense
IFS Applications scores higher across the five modules most critical to aerospace & defense: Manufacturing, Quality Management, Project Management, Procurement, Inventory Management. IFS Applications treats aerospace & defense as a primary market with pricing starting at $110/user/mo. SAP S/4HANA Private Cloud serves aerospace & defense as a secondary market but has weaker scores in key areas like Project Management.
