When you start selling products online, handling transactions is often the most stressful part. If you want to cater to both local and international customers, building separate payment gateways can cause massive headaches. Especially without deep development knowledge, getting stuck at this stage can delay launching your business entirely.
ROYJU helps minimize this hassle by allowing you to set up all necessary payment methods at once. Let us walk through the practical standards for preparing and applying e-commerce payment integration so your customers do not abandon their carts during checkout.
Setting Up Payment Options for Local and Global Shoppers
Website visitors have different preferences. Some want to pay quickly and easily using a smartphone and credit card, while others prefer bank transfers or wire payments. If you are targeting the global market, enabling international currency transactions is also essential.
Generally, e-commerce payment integration relies on these three core pillars:
- Domestic Credit Cards & Express Checkout: Boosts conversion rates with an intuitive interface.
- Bank Transfers / Wire Payments: Ideal for shoppers who prefer direct account transfers or cash receipts.
- International Payments (PayPal): Supports global currencies such as USD, JPY, and EUR.

Step-by-Step Configuration in the Admin Dashboard
In the past, getting approved by a PG (Payment Gateway) provider and embedding complex modules into website source code could take weeks. Nowadays, the process is streamlined by simply entering the required details directly within the builder.
Once you log into the ROYJU admin panel, you can easily locate the payment settings menu. Here, you simply fill out the required fields for your PayApp account info and PayPal integration details. For bank transfers, make sure to accurately input your bank account number and account holder name.
After finishing the setup, you must run test transactions to ensure money flows correctly without errors. One common mistake is entering API keys or merchant IDs with accidental spaces, which causes the payment window to close unexpectedly. Always run a small test transaction after inputting your credentials to verify normal operation.
The Details of Multi-Language Environments and Currency Auto-Conversion
If international visitors land on your site and only see prices in your local currency, they are unlikely to make a purchase. It is crucial to set up your store so that the language and currency adapt automatically based on the visitor's country.
| Payment Method | Supported Currencies | Primary Target Shoppers |
|---|---|---|
| PayApp | Local Currency & Domestic Payments | Local Shoppers |
| PayPal | USD, JPY, EUR, etc. | International Buyers |
| Bank Transfer | Local Currency | Customers Preferring Wire Transfers |
By configuring these options, the appropriate currency and payment module will automatically match depending on where your customer is visiting from. If you run into any hurdles during setup, you can ask the AI agent for quick fixes via chat or refer to the relevant guides.
Connecting Beyond Payments to Reservations and Order Management
If payments go through smoothly but order records are poorly managed, communication with customers will suffer. Once your payment system is successfully linked, you need to establish a routine to check order counts and pending deposit statuses in real time right from your admin screen.
Exact costs may vary depending on your site status and chosen pricing plan, so it is best to review the Pricing page for specific feature scopes. If you want to visualize the finished product first, check out these Example Sites.
