10 Best Trunk Inventory Alternatives

Trunk is a lightweight inventory syncing tool built for ecommerce sellers. It connects platforms such as Shopify, Etsy, Amazon, and maintains consistent stock levels across them.

One of its key features is real-time inventory sync, ensuring that when an item sells on one platform, it’s instantly updated everywhere.

It also supports bundling, which is helpful for merchants who sell kits or combo products made of multiple SKUs.

For smaller catalogs and straightforward setups, Trunk can be a solid starting point. But as your operations grow, it often becomes more of a limitation than a solution.

Where Trunk Falls Short

• Limited functionality beyond syncing: Trunk isn’t a full inventory management solution. It lacks core features like purchase orders, restock forecasting, warehouse tracking, or detailed reporting.

• Not built for scale: If you’re handling a large number of SKUs or processing high volumes of orders daily, Trunk starts to show cracks. Syncing can become unreliable, especially with complex setups.

• Bundle syncing issues: Many users report that Trunk fails to deduct shared components correctly when multiple bundles are purchased in one order.

For example, if Bundle A and Bundle B both include SKU Y, Trunk might only subtract it once, leaving your stock overstated and potentially causing overselling.
