Published at September 25, 2023

Why should you invest in developing with Rails? Because Ruby on Rails is an easy-to-use and powerful tool for building the eCommerce platform you dream of. 

Ruby on Rails e-commerce platform helps reduce the complexity of managing websites for companies. In the latest Stack Overflow developer survey, 7.2% of professional software developers said RoR is a powerful tool.

Expanding your e-commerce platform to reach customers worldwide can significantly increase your business growth potential. 

A critical aspect of international e-commerce is that it supports multiple currencies. However, implementing multi-currency support has its challenges, especially when it comes to integrating payment gateways.

So, how to add multi-currency support to a Ruby on Rails e-commerce store and navigate the challenges of payment gateways in a global market? Let's find out together.

The Need for Multi-Currency Support

Quoted from Bacancy, e-retail sales in 2020 will exceed 3.5 trillion, and they estimate that the share of eCommerce sales in global retail sales in 2023 will be 22%.

E-commerce businesses have a global reach, which means they cater to customers who use different currencies. To provide a seamless shopping experience, offering multi-currency support is imperative. Here are some reasons why:

  • Global Expansion: As businesses expand internationally, they encounter diverse currencies. Supporting multiple currencies allows them to tap into new markets and attract a broader customer base.
  • Enhanced User Experience: Shoppers prefer to see prices and complete transactions in their local currency. This familiarity enhances user trust and comfort, which can lead to increased sales.
  • Competitive Advantage: Providing multi-currency support can be a competitive advantage. It sets your e-commerce store apart and demonstrates a commitment to serving a global clientele.

How to Add Multi-Currency Support to a Ruby on Rails E-Commerce Store

Adding multi-currency support to your Ruby on Rails e-commerce store is a multi-step process that involves both backend and frontend changes. Here's a simplified guide on how to get started:

  • Database Schema: Upgrade your database schema to store product prices and transactions in multiple currencies. This often requires changes to your product and order models.
  • Currency Conversion: Integrate a reliable currency conversion API to provide real-time exchange rates. This ensures that prices are always up-to-date, reflecting the current market conditions.
  • User Preferences: Allow users to select their preferred currency. Store this preference in their user profile or session data.
  • Display Currency: Use the selected currency to display product prices and totals throughout the shopping experience. This includes product listings, shopping carts, and checkout pages.
  • Payment Gateway Integration: This is where the challenges genuinely begin. Not all payment gateways support multi-currency transactions, and those that do may impose restrictions or require additional configuration.

Payment Gateway Challenges

Payment gateways serve as the bridge between your e-commerce store and the customer's financial institution. When dealing with multiple currencies, several challenges can arise:

1. Limited Currency Support

Not all payment gateways support a wide range of currencies. You must choose a payment gateway that aligns with your target markets. Popular gateways like PayPal and Stripe offer extensive currency support, making them suitable for international e-commerce.

2. Currency Conversion Fees

Some payment gateways charge fees for currency conversion. Be sure to understand the fee structure of your chosen gateway to assess its impact on your business's profitability.

3. Currency Precision

Currency precision is a significant concern. Some currencies use decimals differently, leading to rounding errors in your e-commerce platform. Ensure your system can handle different precision levels.

4. Geo-Blocking

Sometimes, International payments restrict transactions from certain countries due to legal or regulatory reasons. This can limit your ability to serve a global audience.

5. User Experience

Providing a seamless and user-friendly experience for customers from different countries is vital. Ensure your payment gateway's integration fits well with your store's design and user interface.

Solutions to Payment Gateway Challenges

To address these challenges, consider the following strategies:

  • Choose a Multi-Currency Friendly Gateway: Opt for payment gateways that provide robust multi-currency support, such as PayPal, Stripe, or Braintree. These gateways often handle currency conversion internally.
  • Real-Time Rate Updates: Regularly update exchange rates to ensure accurate pricing. Implement a mechanism to handle rate updates seamlessly.
  • Refund Policies: Communicate refund policies to customers and consider refunding in the original currency to avoid discrepancies.
  • Consistent Pricing: Monitor exchange rates and adjust prices to maintain consistency. Implement rounding rules to ensure pricing looks clean in all currencies.
  • Legal Compliance: Work closely with legal experts to understand and comply with international currency conversion and taxation regulations.

The Best Payment Gateways for Multi-Currency E-Commerce

Selecting the right payment gateway is paramount for multi-currency e-commerce in Ruby on Rails. Here are some of the top choices:

  • PayPal: PayPal is renowned for its global reach and comprehensive currency support. It seamlessly handles multi-currency transactions and offers competitive conversion rates.
  • Stripe: Stripe is another favourite among developers. It supports multiple currencies and provides detailed documentation for easy integration into Ruby on Rails applications.

To Sum Up
