Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureOther hours apps only hide buttons or show popups — shoppers can still check out. BlockHour enforces your hours at checkout with Shopify Functions: orders outside your hours are rejected before payment, on any Shopify store, with no theme code. Set per-day hours in 30-minute steps, including overnight (e.g. 22:00–02:00).
BoomGate adds a validation layer to your checkout that decides which orders can be completed. Build conditional rules from cart contents, product details, quantities, customer tags, order history, and shipping or billing addresses, then block checkout with a clear custom message when an order doesn't qualify.
