Trunk

Trunk is a cloud‑based multi‑channel inventory syncing platform designed to help e‑commerce sellers maintain real‑time stock accuracy across multiple sales channels. It works as a standalone web application, so there’s nothing to install — you just connect your sales channels and Trunk builds a centralized inventory database from your SKUs. Small and medium online businesses that sell on platforms such as Shopify, Etsy, eBay, Squarespace, Amazon, TikTok, Walmart, and WooCommerce find it particularly useful because it prevents overselling by syncing stock counts instantly whenever a sale happens on any connected channel. Trunk also allows merchants to handle bundles and kits, automatically adjusting component quantities when sales occur, which further simplifies inventory tracking. The onboarding process is quick, setup can be done within minutes, and a 14‑day free trial is available without a credit card. While Trunk excels at syncing real‑time stock levels across platforms, it currently focuses strictly on inventory quantities rather than full catalog or order management features, making it best suited for growing e‑commerce operations needing dependable stock accuracy.
