In this guide to a cross-border payment app, we cover it all from the concept, working process, requirements of the app, methods, and a complete step-by-step development process of a cross-border payment app.

Hence, without any further ado, let’s get started.

What is a Cross-Border Payment App?

A cross-border payment app allows users and businesses to send, receive, and hold multiple currencies across different countries. These apps bypass traditional, slow bank wire systems by offering instant currency exchange and a seamless local payment method.

Depending on the nationality and region, the cross-border payments functionality changes. This cross-border payment industry now utilizes many payment modes such as credit cards, cross-border gateways, wire transfers, e-wallet, distributed ledger technology, APIs, etc., every day to facilitate international payments.

Different determinants of cross-border payment apps are:

• Digital Payments Regulatory and Compliance Frameworks
• User-Facing Interface
• Compliance Modules and Settlement Mechanisms
• Backend Processing
• Beneficiary Payout and Confirmation

But how does the cross-border payment work?

How Does a Cross-Border Payments App Work?

In the fintech market, the apps are unlimited, but the working process of the apps differs based on their targeted market and audience.

The cross-border payment app goes through a complete step-by-step working process:

Step 1: Initiation

Under this step, the sender creates a payment instruction with their bank or even a payment provider. Here, the user enters all the details of recipient’s details, such as bank account number, UP ID, and phone number.

Step 2: Currency Conversion

Here, the sender’s local currency is further converted to the recipient’s currency based on the foreign exchange rates. In this step, the currency is converted only when both currencies are different.

Step 3: Immediate Processing

Banks and fintechs process payments across different networks and systems. It is a real-time backend workflow. This step securely captures the payment details, executes instant compliance screenings, and conditionally settles funds across borders.

Step 4: Compliance Checks

Compliance is mandatory and non-negotiable for the cross-border apps; here, these apps check the compliance for both sides.

Step 5: Settlement

Under this step, you process the complete settlement, where the funds are routed and delivered to the recipient.

Step 6: Confirmation

Both parties get the notification of confirmation related to the payment received and debited. This confirmation is sent via message, mail, and other electronic means.

Here, the fintech startups often ask, “Why should merchants use cross-border payments?”

Why Should Merchants Use Cross-Border Payments?

Do we need a separate money transmitter license for every state or country where we operate?

Yes, you generally need a separate license for every country, or here you can use an EU/EEA passporting system to cover 27 countries or partner with another global banking-as-a-service provider.

Inappropriate licensing can result in voiding the contract agreement of your fintech business, which can even restrict you from a certain region or country. Get a license for your cross-border payment app to launch your business.

Should we build our own payment rails from scratch? What’s the real cost difference long-term?

No, you should not build your own payment rails from scratch unless you process over $100 million annually or payments are your core product, where building custom payment rails is a massive misallocation of resources. If you build it later, the difference can be huge, but building your own payment rails from scratch it will comprises of a wide resources.

The struggle with high transaction costs can end with building your own payment rails; however, building it from scratch will take a lot more resources.

What tech stack should I choose for building a scalable cross-border payment app?

The right tech stack to include for creating a scalable cross-border payment app is a polyglot, API-first architecture that balances real-time foreign exchange with the heavy transaction volume.

For the scalable cross-border payment app, you can make use of cloud-native microservice architecture.

Well, here, most of the startups and fintech enterprises often ask, “What can be the right monetization strategies for my cross-border app?”

The money-making strategies for a cross-border payment app can vary from a subscription model, a usage-based model, and a hybrid model.

In the following section, you can learn them all.

What are the Monetization Strategies for a Cross-Border Payment App?

The key monetization strategies for a cross-border payment app are a subscription model, which combines a fixed recurring fee for API access, a usage-based model, a freemium model, and a transaction fee model.

Let’s discuss all these fintech monetization models below:

1] Subscription Model

The subscription model is a cross-border payment model that helps users and businesses to pay a recurring monthly and annual fee for accessing international transfers and premium financial tools.

Here you will charge the users a recurring fee to access premium features, usually bundled with reduced transfer costs.

2] Usage-Based Models

A usage-based model in a cross-border payment app works by offering a certain number of free requests to the users per month, and then charging the users for further requests.

Here you can consider an example of Google Maps, which offers 28000 requests for free, and the platform charges a suitable amount. This model charges based on the resources used and the API calls that are made.

3] Hybrid Model

Under the hybrid model, you offer a combination of monetization strategies to your customers. Here, you can allow users a subscription policy along with the limited API calls.

When you create a cross-border payment app, you can include the two models as a subscription plan model and a usage-based model.

4] Freemium Model

The freemium model for the cross-border payment app does offer a basic version for free. It lowers the entry barriers to build mass adoption, then uses “upgrade triggers” like usage caps or locked capabilities.

For instance, you can offer the users some free transactions, and then opt for usage caps or locked capabilities.

5] Transaction Fee Model

A cross-border transaction fee model is simple; it charges the customers per transaction through the API. This is a standard model in the fintech APIs.

This model charges for moving money across the digital and geographical borders, and is highly variable depending on facilitating the merchant checkouts, and peer-to-peer remittances.

Well, if you are ready to go ahead with the cross-border payment app development process, then connecting with the right app developers can help.
