# Which ecommerce platforms sync inventory in real time when sales spike during a peak campaign?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">We've been looking at which <a class="a a--md" elv="true" href="https://www.g2.com/categories/e-commerce-platforms">e-commerce platforms</a> sync inventory in real time when sales spike during a peak campaign, and this is the scenario where the difference between platforms that hold up and platforms that create overselling problems becomes most visible. The question is not whether a platform supports inventory sync but whether that sync stays reliable when order volume spikes in a short window.</p><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Three platforms that come up most specifically on real-time inventory performance under load: Shopify, BigCommerce, and NetSuite.</p><ol>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/shopify/reviews"><strong>Shopify</strong></a><strong>:</strong> Centralises product, inventory, and order management so stock levels update in the same backend regardless of which channel the sale comes through; multi-channel selling is built in rather than bolted on; the platform is highly scalable so businesses can grow without worrying about performance degradation. App integrations and customisation options make both standard setups and more specific peak campaign configurations manageable.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/bigcommerce/reviews"><strong>BigCommerce</strong></a><strong>:</strong> Reliable platform with no downtime issues noted across reviewer base; API integrations allow syncing orders and inventory to external systems; used by retail and wholesale businesses that need consistent performance during high-traffic periods; went live within 3 months for one small team with no performance issues since.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/woocommerce/reviews"><strong>WooCommerce</strong></a><strong>:</strong> Open-source with full customisation control over hosting infrastructure; inventory sync during peak periods depends significantly on the hosting setup and plugin configuration, giving teams direct ownership of performance decisions rather than relying on a shared platform.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/salesforce-b2c-commerce/reviews"><strong>Salesforce B2C Commerce</strong></a><strong>:</strong> Enterprise commerce platform designed for large-scale retail operations; built for high-volume peak periods with scalable infrastructure and real-time inventory management across channels; used by enterprise retailers where peak campaign volume is the expected operating mode rather than an exception.</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 teams that have run a platform through a genuine peak campaign spike: where did inventory sync hold and where did it create overselling or stock discrepancy issues, and was the failure a platform performance problem or a configuration issue that could have been prevented?</p>

Oversell during a spike usually isn&#39;t a performance problem or a config bug, it&#39;s a race that exists at any nonzero sync latency. Even &quot;real-time&quot; sync has a floor of a few seconds, and in a peak window your sales rate can exceed that interval, so two channels both sell the last unit inside the same sync window before either learns the other did. That&#39;s why raw speed doesn&#39;t fix it: the real controls are a per-channel safety buffer, holding back a few units so the race can&#39;t reach zero, and decrementing against one authoritative counter instead of per-channel copies.
