Essential features for developing a payment app

It’s imperative to incorporate the following features to align with user expectations and distinguish your offering in the competitive landscape of financial technology:

Peer-to-peer (P2P) transfers

Users should have seamless capabilities to send and receive money, whether for splitting bills, repaying loans, or sharing expenses.

Bill payments

This functionality should encompass bill reminders and scheduled payment options.

Transaction alerts

Real-time notifications are crucial to keep users updated on each transaction made via the app. These notifications build confidence, provide transparency, and assist users in monitoring their financial transactions.

Global money transfer

Facilitating seamless international money transfers, global remittance capabilities are essential for users conducting transactions worldwide. This essential feature should ensure cost-effective and cross-border money transfers.

Multi-currency support

Users involved in international transactions or dealing with diverse currencies should have the ability to operate in multiple currencies, providing them with flexibility and convenience.

Expense management

Expense management features assist users in effectively managing their finances. This includes categorizing transactions, offering insights into spending habits, and providing a comprehensive overview of financial activities.

Customer support

Provide users with various customer support channels, such as live chat, email, and helpline, ensuring instant access and convenience for resolving queries and issues.

7 Steps to develop a payment application

Here are 7 steps to help you define how to develop a mobile payment application that meets modern needs and requirements:

1. Outline your objectives and target audience

The first step is to outline your app’s objectives and identify your target audience. Determine if your app will cater to peer-to-peer transactions, enhance in-store mobile payments, or optimize online purchases. Conduct market research to understand current trends, research the competitor apps and user preferences. It is essential to research the most popular payment apps like Apple Pay, Google Pay, PayPal, and Cash App.

2. Outline payment app features and requirements 

The second phase involves defining the functionalities required and planning their integration into your app. Additionally, consider incorporating advanced features such as contactless payments, biometric authentication, social payments, and cryptocurrency integration, beyond the essential features mentioned earlier.

3. Regulatory and security compliance 

Legal compliance and security of your payment app are essential steps in building user trust. Particularly within the European Union, strict adherence to the General Data Protection Regulation (GDPR) is critical. This involves robust security measures such as firewalls, encryption, and intrusion detection systems to protect sensitive data from unauthorized access. To ensure your app’s security, integrate tools dedicated to detecting and preventing suspicious transactions. This proactive approach not only improves user safety but also ensures compliance with Anti-Money Laundering (AML) regulations. Integrating a Know Your Customer (KYC) module not only ensures compliance with regulatory standards but also enhances the overall security and transparency of your payment application.

4. Choose the appropriate development strategy

The development of financial software demands a methodical approach, characterized by technical proficiency and industry insight. Two primary strategies exist for creating a payment app:

Build software from scratch

Building from scratch offers the advantage of complete customization, guaranteeing that the application aligns with your precise specifications. You retain complete authority over the development process, enabling flexibility and adjustments as necessary. However, this approach is time- consuming and typically entails higher initial expenses due to the extensive time and resources involved.

Use a ready-made Core Banking Platform

Opting for a ready-made core banking software can significantly reduce both the time and costs involved in money transfer app development. Advapay introduces a cloud-based core banking system designed to fast-track your mobile payment app development. With this ready core banking software, you secure a powerful foundation that accelerates app launch and facilitates seamless scalability for various mobile wallet functionalities.

5. Integrate with payment services providers 

Establish integration between your core banking or payment system and essential partners, such as banks, payment gateways, or other financial service providers. Seamless integrations guarantee interoperability and facilitate a smooth flow of funds between your company and partnering entities.

6. Develop a user-friendly interface

Creating a payment app with convenient user interface (UI) and user experience (UX) is crucial for ensuring user satisfaction and adoption on mobile platforms. Here are the examples of payment apps with user-friendly UI/UX:

Intuitive navigation

Intuitive navigation is the key to unlocking user engagement and loyalty. Ensure users can easily access the app, add payment methods, and initiate transactions effortlessly.

Efficient onboarding

Offer your users a streamlined onboarding process, guiding them through account setup and linking their bank accounts. 

Personalization and customization

Enable users to personalize their account settings and preferences. This customization fosters a user-centric design, accommodating individual preferences within the app. Besides, emphasizing a user-friendly interface, personalization, and a streamlined onboarding process are critical in the development of a successful payment app. It is crucial to focus on the following factors: payment gateway features (such as supporting various payment methods like credit/debit cards, mobile wallets, and bank transfers to cater to a diverse user base), compliance, API documentation, and security measures.

7. Launch your payment application

After the payment integration is finalized, release your payment app on the selected platform. It’s also crucial to monitor and maintain it in order to preserve its efficiency and implement any necessary adjustments.
