Fusion Scale Hobbies review for Trunk ‑ Stock Sync & Bundling

July 27, 2025

We really wanted Trunk to be the answer for syncing inventory between our Shopify stores, but unfortunately, it ended up creating more problems than it solved. At first, it seemed like a solid tool, but over time it became a constant headache. The monthly subscription price kept creeping up, which might have been manageable if the software actually worked as expected — but it didn’t. The biggest issue we faced was inventory accuracy. With thousands of SKUs, Trunk repeatedly made mistakes when updating stock levels between stores. We dealt with frequent oversells and found in-stock items marked as unavailable. These errors weren’t just annoying — they hurt our bottom line and disrupted our operations. Fixing these issues required a lot of manual intervention, which completely defeats the purpose of using an automation tool in the first place. It’s been time-consuming, costly, and damaging to customer confidence. After giving it plenty of time and chances to improve, we’ve decided to walk away. If you’re managing a large catalog or multiple stores, be careful — this app might end up doing more harm than good.
