Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureForecast demand, spot stockout risk and plan reorders before you run out. Forecasts learn each product's seasonality, leave out days it was out of stock so lost sales don't read as low demand, and time every order to your supplier's lead time. Add Amazon and both channels plan together, FBA transfers included. Each PO is drafted, then sent or held for approval.
Supremo connects inventory management, replenishment, purchase orders & warehouse operations for Shopify. Use demand forecasting, sales velocity, lead times, safety stock & reorder points to plan what to buy, when & how much. Automatically create purchase orders at reorder points for review & sending to suppliers, or create them in bulk.
