# Can I ensure checkout is blocked if the order does not meet the limit requirements?

**Yes.** To block checkout when orders don’t meet the limit rules, you need to enable checkout validation. This is especially important if your theme is not fully compatible with the app.

Steps:

1. Go to **Settings > Checkout validation** and turn **off** the option *Allow all customers to complete checkout*.
2. In Shopify admin, go to **Settings > Checkout > Checkout rules** (at the bottom) and make sure **Uppush checkout rules** are not disabled.
