Control how many items each customer can buy per order or per day. Prevent bulk buying during launches and ensure every customer gets fair access.
Everything you need to manage purchase limits on your store
Choose between per-order limits (max items per checkout) or per-day limits (max items across all orders in a day). Switch anytime.
Customers see a warning banner and checkout is disabled the moment their cart exceeds the limit. No surprises at checkout.
Daily purchase counts reset automatically at midnight in your configured timezone. No manual intervention needed.
Set your own error message to match your brand voice. Tell customers exactly what the limit is and when they can try again.
Client-side enforcement works on every Shopify plan, not just Plus. No checkout extensibility required.
Set your limit, choose your mode, write your message, and enable. Everything is managed from a simple settings page inside Shopify.
Three simple steps to protect your store from bulk buying
Choose per-order or per-day mode, set the maximum number of items, and write a custom error message.
Go to Theme Editor, toggle on the "Cart Item Limiter" app embed. No code changes needed.
Customers see a warning and checkout is blocked when they exceed the limit. Counts reset daily in per-day mode.
Per-order limits items in a single checkout. A customer with a limit of 4 can place multiple orders of 4 items each. Per-day tracks total items across all orders in a 24-hour period, so a customer with a limit of 4 can only buy 4 items total that day, regardless of how many orders they place.
Yes. The app uses a client-side theme extension that works on all Shopify plans (Basic, Shopify, Advanced, and Plus). It monitors the cart and blocks checkout when the limit is exceeded.
A warning banner appears on the cart page with your custom error message, and the checkout button is disabled. The customer needs to remove items to get back within the limit before they can proceed.
Per-order mode works for all customers including guests. Per-day mode requires customers to be logged in so their daily count can be tracked. We recommend requiring login at checkout if you use per-day mode.
