What is a P2P Payment System

A p2p payment system is a web/mobile application for making electronic transactions from one bank account to another and such platforms utilize payment gateways that handle money transferring operations in a fast and secure way. PayPal, CashApp, and Venmo are among the most popular peer to peer payment software.

 

4 Types of P2P Payment Apps

 

1. Standalone platform

It is a PayPal-like payment system that has its own money transfer payment gateway to facilitate transactions. This type offers full-featured wallet functionality to help end-users store, send, and withdraw funds.

PayPal and Venmo make the list of the top standalone platforms covering >200 countries and 300 mln of users that transfer money daily.

 

2. Bank-centric system

It means a peer to peer payment system developed by a banking institution to simplify the way users can make transactions.

Zelle is the most popular bank-centric P2P payment app designed by the top US financial institutions including Bank of America, Trust, Capital One, JPMorgan Chase, and others.

3. Social media-centric platform

Facebook Pay, Snapcash, and Square Cash are examples of top social media-centric platforms. They mean that end-users can transfer funds directly from the social media app connecting their bank account or debit/credit card.

 

4. Mobile OS focused system

This type of peer to peer payment system includes Apple Pay and Google Pay as the top examples. Mobile OS-focused systems refer to payment service providers integrated right into your iOS or Android smartphone.

Such P2P payment gateways help users transfer funds quickly and easily decrease the cyber threat risks on the operating system’s level.

Must-Have Payment App Features in 2022

 

Digital Wallet

It’s a heart of your P2P payment system as it enables end-users to store, transfer, request, withdraw and top up the funds.

Integrating VISA and Mastercard payment tokenization services is a must as these two providers cover most countries and banking institutions. These services also provide out-of-the-box functionality for your app users thus saving your funds on peer to peer app development.

Here is a great example of a peer to peer payment app digital wallet by PaypPal.

Send & Request Funds

Payment app users mostly perform two key operations – sending and requesting funds from other users. This fact makes it a must-have for your app to implement a robust payment gateway to handle transactions in a secure and lightning-fast way.

 

Send Bills/Invoices

Most organizations and peers tend to request a transaction invoice or bill to make sure the sender has performed the money transferring operation. So, you should implement and offer users an easy-to-use bill/invoice generating feature supporting the most popular formats like PDF, email-centric, and in-app.

Also, implement a convenient way to share the generated bills and invoices with the recipient with single click ease.

Convert Currencies Automatically

Your P2P payment app won’t become valuable and in-demand without an automated currency conversion functionality. Paying for goods and services abroad, making cross-border payments, transferring money to other currency-based cards, and many other activities become possible for users with automated currency conversion.

Technically, you should integrate your peer to peer payment app with exchange rate APIs that will help you handle automatic conversions at the time of each transaction.

 

Unique OTP and IDs

According to KMPG, 72% of enterprises witnessed different types of cyberattacks in 2018. They included phishing, DDoS, exploits of vulnerability, and spam activities that damaged the stability of over 100,000 end-users.

These statistics mean you should pay careful attention to the security of your payment gateway app. Here come one-time passwords (OTP) and unique IDs that users need to enter with the defined frequency. One of the most secure and non-distractive methods is to request an OTP for each login and transaction session.

In terms of unique IDs work similarly, but you can ask end-users to save and store their identifier once while creating their account. It means that hackers have no chance to get a unique ID from the client-side.

Here is an example of OTP and two-factor authentication functionality by PayPal.

Bank Account Transfers

Many users need to transfer funds to bank accounts, not only cards. Providing card-account transactions allows you to stay competitive as this functionality is a must. So, don’t leave your end-users without bank account transfers and meet the needs of any scale.

 

Transaction History

History of transactions helps end-users reconcile their inflows and outflows and keep track of their account’s balance. Try to allow users access as much information as possible.

If you want to stand out from the competition, provide users with deep filters like custom date range, smart sorting, etc. Also, enable customers to generate and download statements convert transaction history into PDFs, and share it via multiple apps and messengers.

 

Push Notifications

A win-win strategy for your payment gateway app. First, you can send new updates, releases, promotions, and offers. Second, end-users can get a notification of account’s receipts, debits, credits, and other activities.

Implement the feature of selecting the types of push notifications customers want to get in the settings so that you can avoid annoying them and keep them on board.

 

Messaging

Quite often, users need to attach comments and details to their money transfers so don’t leave them without this functionality. Implement the chat feature in your payment gateway app and enable users to message others while making transactions.

In case you have a chat app, a payment gateway will also become a great offering for your end-users to send money right there and then.

How to Build Payment Apps: Key Steps to Launch Fast

 

1. Put Your Requirements Together

Start building a payment platform with selecting the type of a payment gateway app you want to implement. As we’ve already discussed, there are 4 key options:

  • Standalone platform
  • Bank-centric system
  • Social media-centric platform
  • Mobile OS-focused system.

 

The type you choose will greatly influence the final money transfer app development costs.

Also, you can launch smartly and save expenses by prioritizing the mobile platform you want to build an app for. For example, you can initially develop your payment gateway app for iOS users.

First, this allows you to save funds on building a payment app on Android.

Second, you can get deep insights into the interests and behavior features of a smaller audience.

 

Next, define the list of must-have MVP features to launch fast and cost-efficiently. They should provide the core value of your peer to peer payment app to end-users.

It means that customers should try your minimum viable product after launch and realize its advantages over competitors. There is no need to implement additional nice-to-have features as the key goal of launching your MVP version is to validate your idea and collect feedback.

What’s more, the list of must-have features will help money transfer app developers understand how to build payment apps you need from a technical point of view.

The more functionality you prepare before money transfer app development, the higher are chances to get the payment gateway app you’re looking for.

 

2. Validate Regulation Compliance

The industry of p2p payment apps and fintech is strictly regulated in many countries. Depending on the region you want to launch your app in, you should conduct deep research. It’s crucial to ensure that your peer to peer payment app will be compliant with the current legislation.

Apart from specific regulations, ensure your app complies with all Payment Card Industry Data Security Standard or PCI-DSS requirements. It’s a one and only must-have standard including 12 requirements to handle cardholder data and become a service provider for card payment transactions.

Acquire the PCI-DSS certificate to boost transparency and trust before launching your peer to peer payment app.

 

3. Design UI and UX

The visually-appealing and modern user interface is a must for your product to compete and succeed. There are two reasons.

 

The interface is the first crucial touch with your end-users.

The more contemporary and killing your design is, the higher chances are you gain users’ hearts. You should make it unique yet intuitive to find the golden mean engaging with customers.

 

Competitors are on the alert.

There are dozens or hundreds of similar offerings in the market. This means your rivals are also trying to follow the latest design trends and amaze end-users with new interface killer features. Think outside the box and embed a high-quality user interface and experience from scratch.

 

You can get inspired and train your visual experience by surfing through Pinterest, Dribbble, and Designspiration where other companies and specialists publish their designs.

In terms of the user experience, we recommend building a clickable prototype, mockups, or wireframes that represent the final user’s flow. This will help you get deep insights into the way customers will navigate through your payment gateway app.

 

4. Build MVP Features

Once your design is in process, you can start implementing the selected must-have MVP features. There are several ways to succeed:

 

Outsource to a money transfer app development company

If you decide to outsource building a payment platform to a company, follow the next simple rules. They will help you choose the most reliable and experienced provider.

 

  • Make sure a company has a solid portfolio.

If the company is proving its background on a blob, then it should become an indicator of double-checking its specific skills. Consider companies that know how to build payment apps based on their expertise and success stories. This will save much time and funds for your business.

 

  • Check testimonials to ensure transparency.

If the provider cannot offer clients’ reviews and testimonials, there are no grounds to believe its words and consider it as an outsourcing company.

 

  • Ask whether a company provides flexible cooperation approaches.

If the company doesn’t offer flexible engagement models, there are high chances to bump into scalability issues during the project development process.

 

  • Ensure a provider offers a project discovery phase.

In case the provider doesn’t offer a project discovery phase, it should become an indicator of the potentially low quality of works. At Ascendix, we offer to conduct a project discovery session in most cases. This allows us to get a deep understanding of the project for both our team and a client.

 

 

Hire freelancers

Freelance teams of money transfer app developers can become a great option as they are dumping the market rates and may offer high-quality services. But we recommend following the next principles when hiring freelancers.

 

  • Try not to opt for the lowest price.

Don’t choose the minimal rates you find on the platform. They often mean a little background and low quality of works that freelance specialists provide. However, it doesn’t mean you can’t find an experienced team of money transfer app developers at affordable rates.

 

  • Pay careful attention to the level of communication.

Better avoid working with foreign freelancers that have communication barriers or a low English level. This will directly influence the final peer to peer payment app quality as the provider should perfectly understand what you need.

 

  • Find and check clients’ testimonials.

One of the core challenges of working with freelance money transfer app developers is the missed deadlines. Take a careful look at the team’s reviews to know what previous entrepreneurs said about working with it.

 

Find a CTO / technical partner

Finding a technical partner for your online payment project is a great yet time- and cost-consuming initiative. The chances are high to spend lots of time on finding a perfect match which increases the time-to-market period and requires lots of your engagement.

But still, an ideal technical partner and CTO should perfectly know how to build a p2p payment app, create a solid technical team, recruit talents, and roll out your payment gateway app to the market.

 

5. Launch, Feedback, Scale

Once the app’s design and features are ready, you should deploy the new version to production and launch your app. The key goal here is to validate your project’s idea through the feedback you will get from early users.

Process any comments to collect as much data from users as possible. The gathered information should indicate what features to change, add, or even remove. Then, convert these notes into a detailed technical specification for money transfer app developers to improve and scale on.

You can perform several test launches and MVP releases. This is normal as your core goal is to transform the minimum viable product and know how to build a mobile payment system with full-featured functionality for end-users. It should be ready to handle thousands of users and provide stability on load.

3 Ways to Monetize Your Payment Gateway App

As an entrepreneur, your key goal is to generate profit from launching and offering a peer to peer payment app. Here are 4 main ways to monetize your money transfer app.

 

Charge Per Feature

One of the core business models is to charge users per feature. This means you provide specific basic functionality for free but offer paid pricing plans. They should include extra features that users are ready to pay as this functionality meets their specific needs.

For example, you can provide users with deep analytics tools and a smart balance moneybox that will automatically round up about 0.1% of each transaction and save it beyond the user’s balance.

 

Charge App Fees

This monetization model means you charge a fixed amount per each transaction so that users get net payments. It is a great yet aggressive business model which may distract some users as they’ve already come up with a specific sum to transfer.

What’s more, refund and chargeback scenarios shouldn’t include additional fees as many users perceive it as non-fair activity. But you can implement flexible payment gateway app fees that work great both for your business and customers.

 

Charge Per Usage

This strategy is similar to the revenue share and app fee models but implies that users pay for high account activity and don’t charge them for each transaction.

This approach works well if you analyze and count the monetary amount over a specific period per user. Then, you can charge customers on a regular basis. The process will become easier if you work with a billing platform that automates per-usage charging for your business.
