Get Listed
A Bill of Materials (BOM) is much more than just a list of components. It’s the foundation of your product, your procurement strategy and, ultimately, your production schedule.
Many manufacturers only revisit their BOM when there’s a problem, perhaps a component has become unavailable, lead times have suddenly increased or costs have spiralled. However, by the time these issues arise, production delays and unnecessary expenses may already be unavoidable.
Regular BOM reviews help identify risks before they become costly problems, allowing procurement teams to improve availability, reduce costs and keep production moving.
Here are ten signs it’s time to give your BOM a fresh review.
- Component Prices Have Increased
Have you noticed the cost of a particular component creeping up every time you place an order?
Price increases can happen for several reasons, including rising material costs, supply shortages, increased demand or manufacturers reducing production.
A BOM review may identify:
Lower-cost alternatives
Multi-source options
Newer replacement parts
Opportunities to consolidate suppliers
Even small savings across multiple components can significantly reduce overall production costs.
- Lead Times Keep Getting Longer
If lead times have increased from a few weeks to several months, it’s a warning sign that supply could become an issue.
Long lead times often indicate:
High global demand
Reduced manufacturing capacity
End-of-life production
Supply chain disruptions
Reviewing your BOM early allows time to source alternatives before production is affected.
- You’re Seeing More Last-Minute Purchasing
If your purchasing team is constantly firefighting, something isn’t working.
Emergency sourcing usually results in:
Higher prices
Increased shipping costs
Greater risk of counterfeit components
Production delays
A proactive BOM review can reduce the need for urgent purchases and improve planning.
- Your Product Contains Obsolete Components
Electronic components don’t stay in production forever.
Manufacturers regularly issue Product Change Notifications (PCNs) and End-of-Life (EOL) notices, meaning certain parts will eventually become unavailable.
A BOM review helps identify:
Obsolete components
Components nearing end-of-life
Suitable replacements
Long-term sourcing strategies
- You’re Relying on a Single Supplier
If only one supplier can provide a critical component, your business is vulnerable.
Unexpected factory closures, shipping issues or allocation policies could quickly halt production.
A BOM review identifies opportunities to:
Qualify secondary sources
Increase supply resilience
Reduce procurement risk
- Production Has Been Delayed by Missing Parts
Even one unavailable component can prevent an entire product from being built.
If you’ve experienced delays due to unavailable parts, it’s worth asking whether those risks could have been identified sooner.
Regular BOM reviews highlight vulnerable components before they become production issues.
- Your BOM Hasn’t Been Reviewed in Over 12 Months
The electronics industry moves quickly.
In just one year:
New components are released
Prices change
Manufacturers discontinue products
Lead times fluctuate
Better alternatives become available
If your BOM hasn’t been reviewed recently, it’s probably no longer fully optimised.
- Your Engineering Team Has Made Product Changes
Even minor design updates can affect sourcing.
New revisions may introduce:
Different package types
New manufacturers
Alternative specifications
Additional compliance requirements
Reviewing the BOM after engineering changes ensures procurement is working from the latest, most efficient version.
- You’re Looking to Reduce Costs
One of the biggest reasons companies request a BOM review is simple, they want to reduce spend.
A professional BOM review can uncover opportunities such as:
Equivalent approved components
Better purchasing options
Manufacturer alternatives
Consolidated sourcing
Reduced logistics costs
Sometimes substantial savings can be achieved without compromising quality or performance.
- You’re Planning Future Production
Perhaps the best time to review your BOM isn’t when there’s a problem, it’s before production begins.
Whether you’re planning for the next quarter or the next year, reviewing your BOM in advance allows you to:
Secure stock early
Lock in pricing where possible
Identify risks before they impact production
Build a more resilient supply chain
Planning ahead almost always costs less than reacting later.
Why Regular BOM Reviews Matter
A BOM review isn’t just about replacing unavailable components. It’s an opportunity to strengthen your entire supply chain.
The benefits can include:
Reduced component costs
Improved availability
Lower supply chain risk
Shorter lead times
Increased production resilience
Fewer emergency purchases
Better long-term planning
For many manufacturers, a BOM review quickly pays for itself through cost savings and reduced disruption.
How Electronics Direct Can Help
At Electronics Direct, we regularly review Bills of Materials for manufacturers across a wide range of industries, including aerospace, defence, medical, industrial automation, telecommunications and many more.
Our experienced sourcing specialists assess your BOM to identify potential risks, long lead-time components, obsolete parts and opportunities to reduce costs or improve availability.
Whether you’re looking to future-proof production, reduce procurement costs or simply gain peace of mind, we’ll provide practical recommendations backed by our global supplier network.
There’s no obligation…just expert advice and a fresh perspective to help reduce costs, minimise risk and save you time.
Final Thoughts
A BOM should never be treated as a static document. Component availability, pricing and manufacturing priorities are constantly evolving, meaning a BOM that worked perfectly last year could now be exposing your business to unnecessary cost and risk.
By reviewing your BOM regularly, you can identify issues early, strengthen your supply chain and keep production running smoothly.
If it’s been a while since your last review, now could be the perfect time to take another look.
