Different Types of P2P Payment Apps That Exist Today

To develop a P2P payment app that triumphs in today’s diverse marketplace – where conventional banking apps, standalone P2P payment apps, Crypto payment apps and social apps with built-in payment coexist – it becomes essential to understand the latest features and trends.

We’ll circle back to that later, but first, let’s look at the types of P2P payment that exist today.

  • Standalone P2P Payment Apps
  • Crypto Payment Apps
  • Messaging Apps with In-Built Payment
  1. Standalone P2P Payment Apps

Payment apps like Venmo and PayPal focus explicitly on payments, unlike traditional banking apps. They don’t rely on any financial institutions and have their own autonomous system for managing and safeguarding funds.

The best feature of these apps is that they act as “Digital Wallets”, allowing users to store money securely in an app, with the flexibility to transfer effortlessly to people we trust or transact to their bank accounts.

  1. Crypto Payment Apps

A crypto wallet app is a P2P payment app letting people send and receive crypto as cross-border transactions. Though, you’ll need to do a lot of homework in finding a P2P payment app for crypto as, say, PayPal. A handful of examples consist of Raby Wallet and BitValve.

Specifically, there’s a lot to pay attention to as crypto tokens and coins have unique addresses. Plus, the payment still needs to be managed by QR codes or type in long strings of symbols for transactions.

  1. Messaging Apps with In-Built Payment

There’s no doubt, social apps like Facebook Pay, SnapCash are no exception to financial domains. These apps allow users to make transactions using credit/debit cards, run a fundraising campaign or donate to creators in a protected climate.

The subtle yet crucial differentiation is that here payments are tightly embedded with a chat.

How Do P2P Money Transfer App Work?

Constant internet connectivity has been the driving force behind P2P Payment app success. Peer-to-Peer payment services allow users to link their bank accounts to the app that facilitates the digital transactions between two people, even if they have accounts in different banks.

It’s not much of a surprise that they have grown in popularity. With more than 8 in 10 consumers admitting to using a P2P app, entrepreneurs and brands should certainly be interested in where their money is going with these apps.

In layman’s terms, P2P money transfer has revolutionized the way we manage our money, making transactions safe, easy and quick. But, how exactly does the P2P payment app work?

Here’s  a brief overview:

  1. User Registration

First and foremost step in using a P2P payment app is registration. Users are required to sign up for an account by providing their personal credentials like, name, email address, contact number etc.

  1. Linking Bank Account

For easy and quick transactions, users must link their bank accounts or cards to the app. This enables seamless transactions between peer-to-peer, peer-to-bank, bank-to-peer, or bank-to-bank.

  1.  Add Contact

P2p payments allow adding contacts within the app for quick and secure transactions. Also, you can search for other users by their registered contact number or email address.

  1. Transaction Initiation

To carry a transaction, users just have to enter the amount and select the recipient from their contact list.

  1. Security Validations

For secure financial transactions, P2P payment apps use several measures like encryption and two-factor authentication.

  1. Transaction Completion

Once a transaction gets successfully completed, users get notification confirming the same.

  1. Balance Management

This is inescapable as it allows users to check on their balance, view transaction history and simultaneously manage their funds.

  1. Fund Withdrawal and Deposit

App users can withdraw money or deposit money to their respective bank accounts instantly.

How to Build a P2P Payment App?

Developing a P2P payment app consists of numerous steps, each ensuring the app’s functionality and success. Let’s have a quick rundown before we explore the nitty gritty.


Much before you start building a P2P payment app, there are numerous things that need attention at priority. It all begins with – “Strategy”.

1.1 Strategize for Your Business Model

Before you kickstart to develop a P2P payment app, it’s important to identify your target audience needs, in other words, study your targeted market and find their pain points in context for using your solution. This will refine your app’s USP (USP) while ensuring it’s a product-market fit.

  • Who will be your app user?

Are you building a payment app for millennials, families, senior people or a community like staying-at-home moms and dads? Can it be used globally? The more demographic features you instill, the more legwork needs to be done.

  • Define what and when of your app for users?

This is just a reference, you can go beyond this – review what situation inspires people to use the app, how often they use the app and will they willingly use the app for on-the-spot, face to face transactions?

  • What monetization strategy should you choose?

Untold startups often skip this aspect. However, it’s strongly recommended to know how your app will make money from the start. After all, this is what matters at the end of the day, right!

Following this will help you understand your already existing competition. Also, you can find a lot of helpful information on trusted software review sites, in-app stores etc.

1.2 Understand and Adhere Regulatory Compliance

Undoubtedly, the feasibility of your idea significantly depends on regulatory compliance. Cross-border payment transaction apps often face challenges because of the varying compliance requirements of every geography.

Therefore, it’s advised to start with the U.S nearby regions. Ensure your fintech app development company is well-versed in working with PI DSS (Payment Card Industry Data Security Standard).

1.3  Handhold Key Partnerships

Building a P2P payment app without key partnership with a financial institution is a fable. Every major neo banking app is backed by a traditional bank, and many follow these trails.

So, weigh your options beforehand and seek key partnerships that will secure payment app features.

1.4 Select a Reliable Tech Partner

After outlining the product-market fit, reviewing legislation barriers, and discussing it with potential partners, it’s time to pick your tech partner.

Here’s a synopsis of the team you’ll be working with:

  • Full-stack developers for the server-side
  • Mobile app developers
  • UX/UI designers
  • QA to minimize errors
  • Project managers to ensure everyone is on the same page
  • Product manager to keep goals aligned with the client’s objective.

Undoubtedly, a battle-tested team well-versed in fintech app development services will assist you throughout the landscape, including technological and business challenges of the envisioned solution.

Step 2: Define and Design the App

Herein, we’ll discuss everything about defining and designing app’s user experience.

2.1 Who’ll Manage the P2P Payment App’s architecture?

To manage the app’s architecture, someone of a CTO (Chief Technical Officer) potential supported with highly skilled mobile wallet app developers is required.

2.2 How Does That Actually Work?

Same like in the game of Lego, here, you choose frameworks, databases, programming languages, APIs, cloud services – almost everything that pour life into your idea.

2.3 Questions To Ask Your P2P Payment App Developers?

Finally, the architecture and tech stack depends on the developer’s expertise and strength. Thus, it is important to follow a collaborative approach, asking questions that matter most to end-users and the owners.

  • How many users will it take to bring the app to a screeching halt?
  • How many transactions are processed /second out the gate?
  • How easily scalability is met?
  • What practices are followed to keep software secure?
  • How easily and quickly a new feature can be introduced in the app later down the road?

These basic questions will lead to fundamental decisions about your P2P payment app.

Step 3: Sketch the App’s UX/UI

This phase includes prototyping. The objective is to craft an engaging graphical shell of the app that anyone can use and easily understand its working. Prototyping can also happen simultaneously with scoping architecture.

3.1 Why Prototyping is Required?

Presenting the graphical shell of an app and collecting all screens together through “hot points” is not even an inch close to the actual cost of developing a P2P payment app. Plus, prototyping takes less time in comparison to complete coding.

Thus, opting for a prototype for your app is a strategic move. It not just proves cost-effective but also allows you to visualize the user journey and ensure the app truly fits in the market gaps. After all, isn’t it smarter to detect roadblocks during the prototyping phase rather than post-development?

3.2 How Does Prototyping Work?

Prototyping is used with a handful of test users matching your demographics to analyze how the app works. As a result, you get insights to leverage in the prototype to make it easy to use and seamlessly address user’s requirements.

Once the UI/UX of the app is done, designers mark up all graphical assets and make them  ready for coders, i.e design hand-off steps in.

Step 4: Magic Behind the Curtain of P2P App Development

You are well-positioned to start P2P payment app development. Though, businesses like you may find this phase boring, let me shed light on it inside-out.

4.1 Who Develops Your P2P Payment App?

This is where development actually starts. Mobile app developers build an app in Android and iOS, full-stack developers engineers code the back-end with databases, APIs and front-end developers develop browser-based money transfer portals for customers as well as admins.

Next, QA engineers help them establish a testing environment and identify any visual and functional error. This collaboration ensures your Peer-to-Peer payment app is error-free and optimized. To ensure everyone is on the same page, the project manager tracks the team’s performance daily. Besides, product managers make sure that the development aligns with the business owner’s vision.

4.2 How Does P2P Payment App Development Work?

At Apptunix, we follow an agile development approach. So, if you partner with a firm on a fixed-price basis, the situation will be different.

With agile, the development process is pretty predictable. The team creates the array of tasks, plan two-weeks sprints, and implement the scheduled tasks while analyzing their performance during the last sprints. Our project managers ensure client’s get complete access to facilitate transparency in the process, ensuring project’s longevity.

And, once you have a market-ready version of the app, you are all set to roll-out the app in the public. Often, the deployment process takes a week, including deploying web apps to a productive environment, uploading apps to app stores, and testing all the functionality again.

The agile approach lets us skip on a slow and often misguided specification phase, saves on time-to-market and ensures seamless and efficient delivery. Simultaneously, agile approach balances the complexities and nuances of creating a P2P payment app with speed, flexibility and customer-oriented development.

In essence, agile approach allows for constant advancements and adaptations, which are crucial in a dynamically evolving fintech market. So, whether it’s addressing the user feedback or adding new functionalities, our agile development approach makes sure your payment app stays up-to-date, catering the needs of your customers effectively.

Step 5: The App Roll’s Out – What’s Next?

Often, business owners don’t pay much attention to post-releasing an app. But, the irony is, the party only breaks up once you launch your P2P payment app.

Firstly, you’ll need to identify opportunities for improving apps based on user feedback. This may include making improvements in user flows or introducing new features (adding a borrowing request choice, etc).

Secondly, ensure your app orchestrates with Apple and Google new mobile OS version releases. After all, update frequency is among the important metrics defining an app’s success.

So, are you all set to build your P2P payment app? Remember, launching the app is just a tip of the iceberg. The journey starts when users begin interacting with your app. It’s a continuous process of learning, refining, and upgrading to cater ever-evolving needs and technological innovations.

On the whole, isn’t it right that the most successful apps are the ones that never stop improving and scaling.

P2P Payment App Development: Proven Best Practices

You must feel like some gaps still exist, like lists of specific technologies or advice on building the admin side of the app.

So, where should you focus when building an online P2P payment app?

The thing is, these imperatives vary significantly from project to project. Still, we are mentioning a handful of things to make sure you get the most of whatever team you partner with.

Voice Oriented Messaging Interface

Imagine completing a transaction with a simple voice command. Sound’s amazing, right!
