See every featureEzy-OTB turns your live Shopify sales data into open-to-buy budgets, demand forecasts, and purchase orders, so buying decisions come from your numbers instead of a spreadsheet that's already out of date. Set category-level budgets tracked against real spend and sell-through, get reorder suggestions before you're caught short, and raise purchase orders from a supplier PDF, a photo, a CSV, or from scratch.
