Checkout alerts

Block payments and display error messages directly on the checkout page for Shopify Plus stores

Unlike Shopify Functions, this extension isn't limited by line item quantity and offers better optimization.

• Go to "Checkout alerts" menu
• Add block "Pareto - Limit Checkout" in checkout page as guide here
• Check "Show notification" option to display an alert when the customer's order does not meet the limit rule.

• Checked "Show product component" option to display details of products that do not meet the limit rule. This allows customers to add or remove products to ensure their order complies with the rule.

Important notes: When enable Checkout Alerts works automatically across Shopify channels, including: Shopify POS, Online Store, Shop App. If a customer’s order violates your limit rules, the checkout will be blocked and the alert message will appear.
