Featured Image

Payment apps are a fast and popular way to make payments and send money for services. One of the most demanded services in modern society. According to the data, about 97% of millennials today use mobile banking applications.

And clients will definitely appreciate the high functionality and perfection of custom payment programs. Therefore, it is worth working on it. So let’s remember how to create payment applications according to the requirements of 2022.

We create a reliable payment app

In order to develop a high-quality and useful app, you should first perform several actions:

  • analyze payment needs and accordingly develop a number of requirements for the app;
  • plan the project: choose a design, including;
  • integrate the app with support and further development.

This is not an easy task, so it costs good money and takes half a year or a year. After all, the process manager, analyst, solution architect, and designers are involved in the project.

Payment apps differ in their capabilities:

Banking app

A traditional way of fast and economical money transfer.

Personal financial app

It is used in a non-bank structure. Can focus on various types of currencies, including digital. Mostly relevant for social networks.

Mobile payment app

It is a digital wallet that autonomously supports online payments. It is convenient to use anywhere and anyone can handle it.

Features of a good payment app

How to decide which app is best for your customers? Consider its functionality and accessibility. It should cover:

  • all types of payments and transfers, including multi-currency ones
  • deep linking technology that directs clients to the payment section with precise amounts, streamlining navigation
  • to be a platform for receiving and sending international transfers;
  • opportunities to work online and offline;
  • processing payments in real-time;
  • the possibility of paying mobile payments.

Tracking of payment histories

In addition, customers should be able to track their payment transactions and have a complete payment history, except for automatic reminders for financial transactions (such as credit card repayments).

Cost management

One of the most important features of a high-quality and convenient payment app is the ability for customers to manage expenses: analyze current and future expenses and automatically receive notifications about them for the corresponding period.

Account management

Most of the operations that the user performs during a certain period – account top-ups, monthly and one-time payments, and others – should be automatic. Having specified a certain algorithm once, the client can count on the app to perform this function for him in the future. For this, the app must contain a custom payment template.

Automatic work with accounts

This is an important point for both companies and users. After all, the former can automatically create and generate the necessary invoices, and the latter can pay in the same way.

Privacy and security

Since the app works with the user’s personal data, it must be protected. Security must meet all international requirements and include multi-level authentication.

How is the cost of a payment app formed?

In order to perform a budget for the costs of creating a payment app, it is necessary to analyze exactly what features it will contain. This series forms the cost of the project as a whole. Example:

  • app type;
  • number and complexity of functions;
  • features of the platform (mobile, web, or combined);
  • number of likely users;
  • interface requirements;
  • scaling capabilities;
  • data protection requirements.

An important point is testing the finished app to identify inaccuracies that will slow down further work. It has several stages and is aimed at monitoring the quality and speed of given operations and opportunities already in the process of work. The best option is continuous monitoring and optimization of the app for compliance with standards, and security rules and to ensure stable operation.

Implementation stages of creating a payment app

In general, there are six stages during which the app is formed, improved, tested, and launched.


All members of the work team are involved, and together with the customer, they determine the features of the future system.


At this stage, the server code, user interfaces, and database are implemented.

Integration of the necessary systems

Here it is determined which systems will be used: banking or other.

Quality control

Multi-stage testing – integration, non-functional and functional allows you to find and correct defects and inaccuracies.


After all the settings and the backup procedure, the payment app appears in the working environment.


This stage continues constantly because it allows not only to support the functionality of the payment app at the initial level but also to improve it.

Based on the results of the features and requirements for the creation of payment systems in 2022, it can be noted that the main focus is on functionality and ease of use. And each app is aimed at maximum satisfaction of the client’s consumer needs.
