Overview

In today’s competitive eCommerce market, collecting accurate customer information during checkout is critical for smooth order fulfillment. Our client, operating an international Shopify store, faced a major challenge with the default checkout system.

Shopify’s standard checkout page collects only basic details such as name, email, phone number, address, and postal code. However, in some countries, such as the Gulf countries and European countries, additional delivery information is required to ensure accurate shipping.

This case study explains how we implemented a custom location based checkout solution in Shopify to solve the issue.

The Problem: Limited Default Checkout Fields in Shopify

The client required extra customer information during checkout, including:

City Name

Specific Location Code

Detailed Area Information

Complete Address Format (as per UAE delivery standards)

However:

Shopify’s default checkout did not provide region-specific dynamic fields.

The client had to manually contact customers for missing information.

Order fulfillment was delayed.

Customer experience was affected.

For customers from Dubai (UAE), detailed address information is essential. But for customers from India, the standard Shopify checkout fields were sufficient. The client needed a location-based dynamic checkout system.

Our Solution: Custom Shopify Checkout UI Extension

We developed a Shopify Custom Checkout UI Extension that dynamically displays additional fields based on the customer’s shipping country.

Key Features of the Solution:

1. Country-Based Conditional Logic

If the customer selects UAE (Dubai) → Additional fields automatically appear. If the customer selects India → Default Shopify checkout remains unchanged. This ensures the checkout experience is smooth and relevant for each location.

2. Custom Checkout Fields Added

For UAE customers, we added:

City Name Field

Specific Location Code Field

Detailed Address Field

Area Information

All fields were validated to ensure accurate data entry.

3. Seamless Backend Integration

The collected custom data is:

Stored within Shopify order metadata

Visible in the Shopify Admin panel

Accessible to the fulfillment team

Ready for shipping label generation

No third-party workaround. Fully integrated with Shopify’s checkout system.

Technical Implementation

We used Shopify Checkout Extensibility features to:

Build secure UI extensions

Apply real-time country detection

Trigger dynamic field rendering

Validate custom input fields

Ensure performance optimization

This solution is scalable and can support additional countries in the future.

Results & Business Impact

After implementing the custom checkout solution:

70% reduction in manual follow-ups

Faster order processing

Improved delivery accuracy in the UAE

Better customer checkout experience

Reduced shipping errors

The client now has a location-aware Shopify checkout system that adapts automatically based on customer geography.
