Days of Cover

Days of Cover tells you which products to reorder, when, and how many units to buy. It ranks by profit rather than sales volume, because your biggest seller is not always the one worth your money. Give it a budget and it funds your most urgent products first, then says what it could not fund. Once a month it estimates what stockouts cost you. Every suggestion expands to its arithmetic. It is read-only: marking a purchase order received here does not change your Shopify inventory.
