Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureYour store is one channel. If you also sell on Amazon or TikTok Shop, your stock, orders and margins sit in separate dashboards that never agree. Inventory Hero reads them together and puts an AI agent on top, so you can ask questions in plain language instead of interpreting charts. Ask which SKUs run out before your next shipment lands, what a product actually earned after fees, or where stock is sitting.
Sizo trains a model on your shop: every product, variant, location and season. It forecasts demand and recommends what to do next, with the reasoning behind it. Planning an order? It recommends how much, in which sizes or variants, and where each unit goes. Days an item was sold out don’t count as low demand. Ask about your shop in plain English and get a decision, not a report.
