OrderRules Store Open Limits
Caps Shopify orders by day, product or customer so you stop overselling what you can't make.
OrderRules is a free Shopify app that enforces daily, weekly or monthly order caps, automated store hours, and per-product and per-customer limits directly at checkout through native Shopify Functions, not just a storefront banner. It also handles delivery and pickup date-and-slot capacity, counting each order against the delivery date chosen rather than the order date, and exports shipment data in the official column layout Japanese carriers require.

Mind the limits
