When launching an online store to sell products or services, the payment system is one of the most critical elements to review thoroughly. If a customer finds an item they like but encounters an error at checkout or discovers their preferred payment method is missing, they will likely abandon the purchase. Especially if you target both local and international shoppers, connecting multiple payment methods smoothly is essential.

If you built your site using an AI website builder like ROYJU, you can easily add payment options by entering a few details directly in the dashboard. Here are the practical steps and benchmarks to follow so you can avoid mistakes and provide a seamless checkout experience for your customers.

1. Setting Up Credit Cards and Manual Bank Transfers for Local Customers

The foundation of running a local online store relies on credit card processing and manual bank transfers. Since these are the most familiar methods for shoppers, omitting them makes generating sales difficult. Navigate to the payment settings menu in your administrative dashboard to locate the domestic payment gateway integration options.

  • Credit Card: Select an integrated payment gateway module such as PayApp, enter your business details, and activate it.
  • Manual Bank Transfer: Accurately input the receiving bank account number and the account holder's name.
  • Display Currency: Set the default currency to match your target region so local customers can view prices comfortably without confusion.

A frequent mistake here is mistyping digits in the account number or using an account holder name that does not match the registered business, which leads to customers inquiring about payment confirmation. After entering the details, run a test payment or place a test order yourself to verify that submissions process correctly.

2. Integrating PayPal for International Customers

If you offer services or physical goods to foreign visitors or overseas buyers, a global payment solution like PayPal is indispensable. If your multilingual website supports multiple languages, ensure that currency displays automatically convert to the appropriate currencies as well.

When connecting PayPal, verify that your business account is properly linked and that the redirect settings returning customers to your site after payment completion work smoothly. If you encounter hurdles during the setup process, refer to the AI agent or administrative guides for troubleshooting.

3. Finalizing Order and Payment Management

Once payment integration is complete, test whether you receive immediate admin notifications upon new orders and verify that order forms and payment statuses update in real time. Clearly display your refund and cancellation policies near the footer or checkout pages to minimize unnecessary customer service inquiries.

Exact pricing can vary depending on the chosen subscription plan or additional services, so reviewing the pricing information page beforehand is recommended. Rather than aiming for absolute perfection on day one, we suggest completing the basic setup, running test transactions, and refining details gradually.
