How Hardware Engineering Services Solve BOM Cost Challenges

Technology May 26, 2025 29 Add to Reading List

In the development of any hardware product, one of the most critical aspects is managing the Bill of Materials (BOM). The BOM includes a detailed list of all the materials, components, subassemblies, and the cost of each required to manufacture a product. Accurate and optimized BOM cost management directly impacts a product’s final price, time-to-market, and overall profitability. This is especially crucial for companies operating in the IoT (Internet of Things) space, where components and sensors must be sourced from various suppliers globally, and cost efficiency plays a key role in competitiveness.

A recent Gartner report forecasts that IoT-enabled devices will account for more than 20 billion devices by 2025. As demand for IoT solutions grows, so do the complexity and cost considerations of the hardware that powers them. This makes efficient BOM management even more important for IoT manufacturers, who must balance performance, cost, and component availability.

In this article, we will explore how hardware engineering services help businesses address BOM cost challenges, optimize their supply chains, and ensure the efficient and cost-effective production of IoT devices. We will also highlight the role of IoT hardware development companies and embedded software services in tackling these challenges.

The Importance of Bill of Materials (BOM) in Hardware Development

The BOM serves as the blueprint for a product’s assembly. It specifies every component that goes into the design, as well as its associated costs. From microcontrollers and sensors to circuit boards and connectors, a BOM is central to both the engineering and manufacturing processes.

A poorly managed BOM can lead to:

Overpriced components: Sourcing from the wrong suppliers or failing to optimize the component selection.
Supply chain inefficiencies: Delays in procurement or shortages of critical components.
Design rework: Changes in component selection or specifications leading to cost increases.
Increased time-to-market: Slow or costly iterations of product development due to poor cost management.

With these potential risks in mind, managing BOM costs is a critical focus for hardware engineers and product developers. Let’s examine how effective hardware engineering services can mitigate these challenges.

Key Challenges in BOM Cost Management

1. Component Sourcing and Supplier Management

One of the biggest challenges in managing BOM costs is sourcing the right components at the right price. With many IoT products requiring specific components like sensors, microcontrollers, and wireless communication modules, identifying reliable suppliers who offer competitive prices is crucial.

Challenge: Sourcing high-quality components at a reasonable cost can be difficult, especially when working with international suppliers. Exchange rates, tariffs, and supplier reliability can introduce unpredictable costs into the BOM.
Solution: Hardware engineering services often include expertise in supplier management, allowing businesses to select suppliers based on factors like cost, lead time, and quality. These services help build relationships with trusted suppliers, negotiate better terms, and even identify alternatives when a component is out of stock or too expensive.

2. Overengineering

Overengineering is when a design includes unnecessary or overly complex components that increase BOM costs without providing proportional benefits. It’s easy to get caught up in choosing advanced components for the sake of performance, but this approach can significantly inflate costs.

Challenge: Engineers may select high-end components like premium microcontrollers or sensors that deliver superior performance but add considerable cost to the BOM.
Solution: IoT hardware development companies are skilled at understanding the balance between performance and cost. They can help optimize designs to ensure that the right components are selected, avoiding unnecessary features while meeting the product’s technical requirements.

3. Manufacturing Process Complexity

The more complex the manufacturing process, the higher the associated costs. This includes the type of assembly required, the difficulty of component placement, and the testing procedures involved.

Challenge: Some components require specialized assembly or testing, which increases labor costs and production time.
Solution: Hardware engineering services can optimize the design for manufacturability (DFM). This includes ensuring that the product is easy to assemble, minimizing the need for specialized manufacturing processes, and designing for high yields in production.

4. Component Obsolescence and Lifecycle Management

The lifespan of electronic components is finite. As new versions of components become available, older ones are phased out or discontinued. This can create challenges in sourcing components, especially for products with long development cycles.

Challenge: If a key component is discontinued or its availability becomes limited, the BOM must be updated, often resulting in higher costs or sourcing challenges.
Solution: By maintaining strong supplier relationships and staying informed about component life cycles, hardware engineering services can help ensure that the BOM remains up-to-date and avoid last-minute sourcing difficulties. Additionally, they can select components with longer life cycles to minimize disruption.

5. Custom vs. Off-the-Shelf Components

Custom-designed components often come with higher upfront costs, whereas off-the-shelf components are typically more cost-effective but may not always meet the exact requirements.

Challenge: The decision to use custom components may increase initial costs, but relying entirely on off-the-shelf components may limit the product's functionality or performance.
Solution: Experienced hardware engineering services help companies make informed decisions on whether to use custom or off-the-shelf components, ensuring that the design meets both performance requirements and budget constraints.

How Hardware Engineering Services Help Solve BOM Cost Challenges

1. Component Optimization

One of the primary ways hardware engineering services address BOM cost challenges is by optimizing the selection of components. They analyze the requirements of the device and recommend components that strike the best balance between performance and cost. This may involve:

Alternative components: Identifying lower-cost alternatives that still meet the technical specifications.
Standardization: Reducing part count by selecting components that serve multiple functions or can be used across different products.
Bulk sourcing: Negotiating bulk discounts or long-term contracts with suppliers to reduce per-unit costs.

2. Design for Cost Efficiency

Hardware engineers are adept at designing products with cost efficiency in mind. This includes:

Minimizing board size: By optimizing the PCB layout, engineers can reduce the number of layers and materials needed.
Reducing part count: Engineers analyze the circuit design to reduce the number of components while ensuring functionality is not compromised.
Design for manufacturing: The design process includes considerations for ease of assembly, reducing the need for manual interventions and expensive manufacturing processes.

3. Supply Chain Optimization

Hardware engineering services often work closely with supply chain managers to ensure smooth procurement of components. They can:

Negotiate pricing: They help secure better terms with suppliers by leveraging long-standing relationships and bulk purchasing.
Ensure availability: By working with reliable suppliers, engineers can reduce the risks of stockouts and delays in component availability, which can lead to higher procurement costs.
Identify alternatives: If a component becomes unavailable or too expensive, they can quickly identify alternatives that meet the requirements.

4. Prototyping and Testing

Prototyping allows hardware engineers to test a product design before full-scale manufacturing begins. This iterative process ensures that potential issues in design, cost, or functionality are identified early on. With prototypes, engineers can:

Optimize the BOM: Engineers can analyze prototypes to ensure that the components selected provide the best value and functionality.
Test manufacturability: Testing the product at the prototype stage allows for adjustments that can reduce complexity and cost in the final product.

5. Lifecycle Management and Sustainability

Managing the lifecycle of the product is a critical aspect of BOM cost optimization. Hardware engineers help businesses make informed decisions about component longevity and sustainability, ensuring that products remain cost-effective over time.

Sustainable sourcing: Engineers can prioritize sourcing components that have longer lifecycles or are more widely available, reducing future BOM risks.
Component reusability: In some cases, components can be reused in multiple products, driving down the cost for future iterations.

The Role of IoT Hardware Development Companies and Embedded Software Services

IoT hardware development companies play a pivotal role in solving BOM cost challenges by offering expertise in selecting, sourcing, and optimizing components for IoT devices. These companies bring deep knowledge of the IoT ecosystem, supplier relationships, and cost-effective hardware design practices.

On the software side, embedded software services also contribute to optimizing BOM costs. They ensure that the software interacts efficiently with the hardware, which can reduce the need for additional or more expensive hardware components. For instance, low-level software optimizations can enable better utilization of hardware resources, lowering the need for high-end components.

Conclusion

Managing BOM costs is a critical challenge for hardware development, particularly in the rapidly evolving world of IoT. Effective hardware engineering services offer a range of solutions to address these challenges, from optimizing component selection to ensuring design for manufacturability and supply chain efficiency. By leveraging the expertise of IoT hardware development companies and embedded software services, businesses can significantly reduce BOM costs while maintaining product quality and performance.
