Top 10 Aerospace and Defense ERP Systems in 2024

Last Updated on March 17, 2025 by Sam Gupta

Aerospace and defense industries face unique challenges due to stringent quality and regulatory requirements. Unlike consumer-driven automotive sectors, A&D operates with long sales cycles and uncertainties, making supply chain planning intricate. The custom nature of A&D products, coupled with formal revision tracking, adds complexity, necessitating ERP systems with unique BOM structures. While collaboration with local suppliers has its own challenges, international supplier collaboration dictates trade compliance requirements at another level because of national security and geopolitical issues.

Equally challenging are manufacturing processes that vary per business model, requiring solutions tailored to each. While some ERP systems suit plastic manufacturers serving A&D OEMs, others offer versatility for diverse global business models. Despite looser margin requirements in A&D compared to automotive, stringent quality standards can impact margins. Highly engineered aerospace parts demand precise vendor collaboration and time sensitivity to avoid supply chain disruptions.

A&D companies engage in extensive pre-sales processes, involving multiple stakeholders and proofs-of-concept during R&D. This uniqueness underscores the need for ERP systems with built-in engineering and pre-sales workflows to support contract requirements. Some business models might require access to proprietary databases, integration with industry systems, and compliance requirements related to the upkeep of processes. Choosing an ERP system for the A&D industry requires a deeper study of business models and transactions, as generic solutions may necessitate significant investments in longer implementation cycles, which might be out of the range of most SMB companies. Find out which ERP systems are designed to meet the distinctive needs of the A&D sector.
