In today’s complex manufacturing environment, a single error in your component inventory can trigger a costly cascade of production delays and quality issues. For machine builders, the stakes are exceptionally high—with each build integrating hundreds or thousands of parts, the risk of costly mistakes multiplies exponentially. The implementation of proper software bill of materials (SBOM) systems has become not just advantageous but essential for compliance with the Cyber Resilience Act (CRA) and operational excellence.
At Noux Node, we’ve witnessed firsthand how machine builders transform their operations through advanced digital solutions that eliminate inventory discrepancies, version control issues, and procurement bottlenecks. The right management system doesn’t just prevent errors—it becomes the foundation for innovation and competitive advantage.
This guide unpacks how innovative low-code BOM solutions can revolutionize your production processes, slash costly errors, and position your business for sustainable growth in an increasingly regulated industry landscape.
The hidden costs of BOM errors in machine building
When a bill of materials contains even minor inaccuracies, the financial impact reverberates throughout the entire production cycle. Industry research reveals that BOM errors typically cost manufacturers between 4-5% of annual revenue—a staggering figure for businesses operating on slim margins. For a mid-sized machine builder with €10 million in revenue, that translates to €400,000-€500,000 lost annually to preventable mistakes.
The most insidious BOM errors include outdated component specifications, incorrect quantity calculations, and missing regulatory compliance documentation. These seemingly small oversights trigger expensive rework cycles, delayed shipments, and in worst-case scenarios, field failures that damage customer relationships permanently. One European machine builder recently reported a three-week production delay costing €75,000 when an incorrect component version was specified in their BOM, resulting in compatibility issues that weren’t discovered until final assembly.
Beyond immediate financial impacts, BOM errors create significant operational inefficiencies as engineering and production teams divert valuable time to troubleshooting instead of innovation. Without proper BOM management, meeting CRA compliance requirements becomes virtually impossible, exposing manufacturers to regulatory penalties and market access limitations.

Why traditional BOM management approaches fall short
Despite their widespread use, conventional approaches to managing bills of materials create more problems than they solve in today’s complex manufacturing landscape. Spreadsheet-based systems—still used by 67% of small to mid-sized machine builders—present critical limitations in version control, often resulting in multiple conflicting “sources of truth” circulating across departments.
Manual tracking processes not only consume excessive labor hours but introduce abundant opportunities for human error. One misplaced decimal or transposed part number can initiate a chain reaction of manufacturing mistakes. Most concerning is the disconnect between engineering BOM systems and procurement platforms, creating dangerous information silos where critical updates fail to propagate through all stages of production.
Traditional approaches also struggle fundamentally with the increasing complexity of modern machinery, where software components and hardware elements must be tracked with equal precision to ensure proper functionality and regulatory compliance. As CRA requirements intensify scrutiny on software supply chains, these legacy systems leave machine builders exposed to significant compliance risks and security vulnerabilities.
“Managing our bill of materials through disconnected systems was costing us nearly two days of engineering time per project. The inability to track component changes across departments created constant rework and compliance headaches.” – Manufacturing Engineering Director
Key features of effective CRA machine builder BOM software
Modern bill of materials management solutions deliver transformative capabilities that address the unique challenges machine builders face. At the foundation is centralized data management—creating a single, authoritative source of truth that eliminates version conflicts and ensures all stakeholders access current information. Automated validation tools instantly flag potential issues like missing components, duplicate entries, or compatibility conflicts before they impact production.
Component standardization features enable manufacturers to reduce parts proliferation by identifying opportunities to use preferred components across multiple machine designs, streamlining procurement and reducing inventory costs. The integration with procurement systems creates a seamless digital thread from design to purchasing, eliminating transcription errors and ensuring accurate ordering.
For manufacturers navigating CRA compliance requirements, advanced software provides essential tools for tracking software dependencies, documenting component origins, and generating compliance reports. The ability to manage both hardware and software elements in a unified system is particularly critical as industrial machines increasingly blend physical components with sophisticated control software.

Implementing BOM management systems: Best practices for success
Transitioning to a robust bill of materials solution requires thoughtful planning and execution. Begin with comprehensive data assessment—understanding your current BOM structure, identifying information gaps, and establishing data cleansing protocols. Successful implementations typically follow a phased migration approach, starting with a single product line to validate processes before expanding company-wide.
Invest adequately in team training, recognizing that technology adoption depends on user acceptance. Cross-functional implementation teams yield the best results, incorporating perspectives from engineering, manufacturing, procurement, and quality control. Establish clear workflow protocols that define review processes, approval hierarchies, and change management procedures.
Measuring implementation success requires establishing baseline metrics before deployment, then tracking improvements in key indicators like BOM accuracy rates, engineering change order processing time, and component standardization percentages. The most successful implementations maintain executive sponsorship throughout the process, ensuring adequate resources and organizational alignment.
Case study: How manufacturers reduced errors by 85% with BOM software
A Finnish automation equipment manufacturer struggling with recurring production delays implemented our low-code BOM management system across their operation. Within six months, they documented an 85% reduction in BOM-related errors, translating to approximately €240,000 in saved rework costs annually. Their engineering change order processing time decreased from an average of 14 days to just 3 days, dramatically improving responsiveness to market changes.
Similarly, a German machine builder specializing in packaging equipment leveraged advanced BOM software to standardize their component library, reducing unique parts by 30% and negotiating better supplier pricing through consolidated purchasing. Their procurement team reported a 42% reduction in emergency orders and expedited shipping fees, while inventory carrying costs decreased by 18%.
Beyond operational improvements, both companies reported significant advantages in meeting regulatory requirements through streamlined SBOM generation and documentation. The ability to quickly produce compliant bills of materials for CRA certification eliminated compliance bottlenecks and accelerated time-to-market for new machinery.
