# Which PLM software keeps the bill of materials accurate across multiple design revisions without engineers having to manually reconcile changes?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">I am looking for input on <a class="a a--md" elv="true" href="https://www.g2.com/categories/product-lifecycle-management-plm">product lifecycle management (PLM) software</a>, specifically on BOM accuracy across design revisions, the specific failure mode where a design change in CAD doesn't automatically propagate to the BOM, and engineers are manually reconciling two disconnected sources of truth, and production releases are built from a BOM that no longer reflects the actual design.</p><ol>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/openbom/reviews"><strong>OpenBOM</strong></a><strong>:</strong> CAD add-ins for SolidWorks, Fusion 360, and other tools automatically generate and update BOMs directly from CAD assemblies. Version tracking across multiple levels of the BOM allows teams to see the current version and trace back to previous states without digging through folder structures.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/siemens-teamcenter/reviews"><strong>Siemens Teamcenter</strong></a><strong>:</strong> BOM management is a primary daily use case, tracking parts and assemblies with a clear revision history that is easy to follow, identifying duplicate parts and flagging reuse opportunities, and automatically identifying impacted components when dependencies change. </li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/arena-plm/reviews"><strong>Arena PLM &amp; QMS</strong></a><strong>:</strong> BOM management with complete revision control is a core Arena capability. It can compare BOMs across revisions, identify exact changes between versions using the redline feature, and maintain where-used visibility for all components.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/duro/reviews"><strong>Duro</strong></a><strong>:</strong> BOM accuracy is maintained without requiring a dedicated PLM administrator to keep it clean. Designed for hardware startups and growing engineering teams that need BOM discipline from early in the product lifecycle rather than retrofitting it after the product is in production.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/aras-innovator/reviews"><strong>Aras Innovator</strong></a><strong>:</strong> The open platform architecture allows organizations to configure exactly how BOM changes propagate through the change management workflow, including the approval gates required before a BOM revision is released to manufacturing.</li>
</ol><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">For engineering teams that have dealt with BOM drift, at what point in the product lifecycle does the reconciliation cost become unsustainable? Is it during NPI when design is changing daily, during production when a BOM error triggers a recall, or during an audit when the history can't be reconstructed?</p>

&lt;p&gt;This usually isn’t just a PLM problem. If engineers are still making changes directly in CAD without thinking about downstream impact, even a good system won’t save you. The tools help, but discipline still does a lot of the work here.&lt;/p&gt;
