Which App to Choose
You were using Shopify built-in inventory tool and need a replacement, or you've outgrown spreadsheets and need to manage purchase orders, track multiple suppliers, and get low-stock alerts before you run out. EZStock covers the full PO lifecycle: create an order in DRAFT, mark it SENT when you email the supplier, mark RECEIVED when inventory arrives and stock updates automatically. Best for: Shopify-first brands with 50–2,000 SKUs managing restocks manually or via the built-in inventory tool.
You want the app to tell you what to order and when — not just manage the PO once you decide. Prediko uses AI forecasting to predict stockout dates based on your sales velocity and lead times, then auto-generates PO suggestions. Best for: merchants with seasonal demand swings or high SKU counts where manual reorder decisions become unmanageable.
Trunk is the right choice when you sell the same inventory on Shopify, Etsy, Amazon, and eBay simultaneously and need one source of truth for stock levels. Shopventory is built for merchants with multiple physical store locations and POS systems who need location-level reporting and transfers.
EZStock is free to install — replace built-in inventory tools in under 10 minutes
Purchase orders, supplier management, low-stock alerts, and COGS tracking — natively in Shopify. No spreadsheets, no built-in inventory tool needed.
