Key Features & Functional Overview

CartWisp provides a structured checkout governance system that allows Shopify merchants to control how checkout behaves based on operational policies, compliance requirements, customer eligibility, shipping restrictions, payment conditions, and advanced cart validation logic.

The platform is organized into multiple functional systems that work together to help merchants:

  • Prevent invalid orders
  • Reduce operational overhead
  • Improve checkout compliance
  • Protect fulfillment workflows
  • Control payment and shipping behavior
  • Enforce customer eligibility
  • Create more predictable checkout experiences

This page provides a detailed overview of the major capabilities available across CartWisp plans.

Basic Checkout Validation & Protection​

Minimum Order Value Enforcement​

CartWisp allows merchants to enforce minimum cart subtotal requirements before checkout can be completed.

This feature is commonly used by:

  • Wholesale stores
  • Delivery-based businesses
  • Margin-sensitive operations
  • Bulk order workflows

Example:

  • Require orders above $40 before checkout.
  • If the cart subtotal does not meet the required threshold, CartWisp blocks checkout and displays a validation message explaining the requirement.

Example customer message:

  • Minimum order value is $40. Please add more items to continue.
  • This helps merchants prevent unprofitable or operationally inefficient orders.

Maximum Quantity Per SKU​

CartWisp allows stores to limit how many units of a specific product can be purchased within a single order.

This feature is especially useful for:

  • Flash sales
  • Promotional items
  • Limited inventory products
  • Anti-reseller protection
  • Controlled inventory releases

Example:

  • Limit promotional item to 1 unit per order.
  • If the customer exceeds the allowed quantity, CartWisp prevents checkout until the quantity is corrected.
  • This helps merchants prevent inventory abuse and maintain fair product allocation.

Country & State Blocking​

CartWisp supports region-based checkout restrictions using country and state validation.

This feature allows merchants to prevent checkout for unsupported or restricted regions.

Example:

  • No alcohol shipments to Utah.
  • This is useful for:
    • Compliance enforcement
    • Restricted product sales
    • Operational delivery boundaries
    • Geo-sensitive products
  • If a restricted region is detected during checkout, CartWisp blocks the order before payment is completed.

Checkout Blocking with Clear Validation Messaging​

CartWisp can block checkout whenever configured rules are violated.

Instead of allowing invalid orders to proceed, CartWisp displays customer-friendly validation messages that explain:

  • What caused the restriction
  • Why checkout cannot continue
  • What action the customer should take next

Example:

  • Remove restricted item to continue.
  • This creates a more transparent checkout experience while reducing operational issues after purchase.

Disable Specific Payment Methods​

CartWisp allows merchants to dynamically restrict payment method availability during checkout.

Example:

  • Disable Cash on Delivery for international orders.
  • This feature helps merchants:
    • Reduce payment risk
    • Enforce payment policies
    • Prevent unsupported payment scenarios
    • Control region-specific payment behavior
  • Payment restrictions can be based on:
    • Customer location
    • Product type
    • Cart value
    • Customer category
    • Order risk conditions

Basic Rule Testing Mode​

CartWisp includes rule preview functionality that allows merchants to test rule behavior before activating it on a live store.

This helps merchants:

  • Prevent accidental checkout disruption

  • Test customer scenarios
  • Review rule outcomes safely

Rule testing mode is useful for stores implementing checkout controls for the first time.

Advanced Cart & Product Logic​
