Kark: Multi Location Inventory

Using this app for nearly 2 years across 12 warehouse locations. Does exactly what it promises: shows per-location stock on every product page, with virtually zero setup once installed.

What really stands out is the support. Kets has been incredibly responsive — we had a sync timing issue on draft products, he enabled a draft opt-in for us within hours. We then asked for a per-product Flow action, and he shipped it in days. Custom support like this is rare on the App Store. Highly recommended.
