Checkout Customization and Payment Rules Engine for a High Growth D2C Fashion Brand

Overview

In high growth ecommerce, acquisition often gets the spotlight. But for a rapidly scaling D2C fashion brand operating across UAE and Saudi Arabia, revenue leakage was happening much later in the funnel at checkout.

Despite strong traffic and healthy demand, the brand faced a 34 percent cart abandonment rate during checkout, significantly above regional benchmarks.

Analysis revealed the issue was not product or pricing but payment experience friction and lack of personalization.

The objective was to redesign checkout into a dynamic payment decisioning system capable of:

• Reducing cart abandonment

• Increasing prepaid conversions

• Improving BNPL adoption

• Controlling COD risk exposure

• Optimizing checkout performance

The final solution introduced a Shopify Functions based Payment Rules Engine designed to personalize payment visibility in real time.

Problem Statements

• High checkout abandonment rates

• Cash on Delivery overexposure

• Low prepaid order adoption

• No payment personalization

• High return to origin losses

• Manual intervention for risky orders

The checkout experience remained static while customer behavior and risk continuously changed.

Challenges

Payment Preference Misalignment

Cash on Delivery appeared as the default payment method despite increasing customer preference for digital payment options.

• Lower prepaid conversion

• Reduced cash flow predictability

• Higher checkout friction

Uncontrolled COD Risk

All customers had equal payment access regardless of behavioral signals.

• 28 percent return to origin rate

• Higher reverse logistics cost

• Operational inefficiencies

Lack of Checkout Intelligence

• No real-time payment evaluation

• No customer segmentation

• No dynamic payment visibility

Process

Step 1: Checkout Audit and Behavioral Analysis

The team evaluated:

Step 2: Shopify Functions Payment Rules Engine

Amwhiz implemented PayRules using Shopify Functions.

Payment methods were dynamically controlled using:

Buy Now Pay Later options were prioritized for:

• Orders above AED 200

• Returning customers

• Low risk customer profiles

Step 5: Time Based Rule Scheduling

Dynamic restrictions adjusted payment behavior during:

• Post Eid periods

• January refund cycles

• Known high RTO windows

Step 6: Analytics and CRM Integration

The solution included:

• Prisma optimization layer

• HubSpot CRM integration

• Conversion monitoring

How the System Worked
