Yes, Simple Bundles excels at inventory sync for 3PL and fulfillment centers. When a bundle is sold, it automatically breaks down the order into individual SKUs, allowing your fulfillment team to pick and pack each item separately. The app integrates with major 3PL providers, warehouse management systems (WMS), and shipping services like ShipStation. This prevents overselling and ensures accurate inventory tracking across all sales channels, reducing fulfillment errors by up to 80% according to merchant feedback.

This feature allows customers to create fully customizable bundles with unlimited product combinations, free from Shopify's variant restrictions. You can build dynamic mix-and-match bundles, subscription boxes, or wholesale packs with thousands of possible configurations. The backend handles all the complexity while providing a smooth customer experience on your storefront.
