Digital lending is picking up steam. Key factors driving the rapid growth include:

• the increasing adoption of digital technologies and smartphones,
• the need for a better experience for lenders,
• government commitment to protecting digital lending,
• greater transparency and options for borrowers and lenders,
• growing demand for digital lending platforms among SMEs, etc.

Experts say the demand for such solutions will only increase. According to the report by Vantage Market Research, the global digital lending market is expected to grow to $22.4 billion by 2028.

As borrowers appreciate the benefits of digital lending over the traditional loan application process, banks, and other financial institutions need to become more digitally driven to keep up with fintechs that are ahead of the competition with their fast, creative, and convenient solutions. The good news is that starting a loan app isn’t as difficult as it seems at first glance. Read on to learn how to create a money lending app, what integrations will come in handy, loan lending app development costs, and what pitfalls you should avoid.

How to Create a Money Lending App – Itexus Expertise

Let’s take a closer look at the steps involved in developing a money lending app. To help you better understand the process, we’ll illustrate it with the example of our recent project, an online lending platform for small businesses. It is a digital lending platform with a mobile app client that fully automates the entire lifecycle of a loan – from online loan application, KYC, and credit scoring to underwriting, payments, reporting, and bad deal management. The app features a custom AI analysis and scoring engine, virtual credit cards, and integration with major credit reporting agencies and a bank account aggregation platform. The following team was involved in this project: 2 iOS developers, 1 project manager, 1 business analyst, 1 data scientist, 3 backend developers, and 1 QA engineer.

Step 1. Discovery Phase

The discovery phase is the research and planning phase that allows to fully prepare for the loan app development phase. It focuses on gathering essential information about the project, specifying requirements, determining the scope of work, validating assumptions, designing the solution architecture, defining the product roadmap, and accurately estimating loan lending app development time and cost. If you want your project to stay on budget, be delivered on time, and be successful once released, you should begin discovery.

During this phase, our business analyst and software architect conducted a thorough market and requirements analysis and created the initial project documentation. As a result of the discovery phase, our client received the following deliverables:

Software Requirements Specification (SRS)
This is a document describing all functional requirements with use cases, diagrams, user screen mockups, user journey, etc.
Software Architecture Document (SAD)
This document describes the suggested technology stack and architecture of the system considering third-party integrations, security, performance, reliability, and other non-functional requirements.
• Project plan and work estimate
A detailed project plan with all work divided into iterations, established priorities, dependencies, and team structure.

Step 2. UI/UX Design

A simple and intuitive design is crucial for the overall success of the project. Your solution should help users complete their tasks quickly and easily. The simpler the interface is, the easier it will be for users to navigate it, and the more comfortable it will be to use your app. Conversely, an app overloaded with icons and features will put users off. Therefore, it is important to find a balance between functionality and utility. This is where UI/UX designers come in. Experienced specialists will apply best practices to ensure that your lending app is easy and enjoyable to use.

In this step, UI/UX designers create an intuitive user interface for your future lending app. Marketing materials such as landing pages, promotional videos, etc. can also be created at this stage.

Step 3. Development

Depending on the project scope and specifics, the team works according to one of the many project management methodologies. For our lending app project, we used the Agile/Scrum methodology. The loan lending app development process was divided into two-week sprints, with demonstrations of the new product versions and feedback gathering at the end of each sprint. This phase involves developing and deploying the app itself and integrating it with third-party services. It also includes a combination of unit tests, automated service and UI level tests, and manual testing.

Step 4. Launch, Support & Maintenance

After the app is live, it needs to be updated and maintained. You can do this yourself (in this case, you need to have in-house specialists) or continue to work with your loan app development team if they provide support and maintenance services.

Digital Lending Development: Pitfalls & Best Practices

Over the years of hands-on experience in software development for financial services companies, we’ve got a solid grasp on all fintech ins and outs. We know how to create a money lending app that will bring value to your business – and we are happy to share that knowledge with you. Below, we’ve listed the pitfalls you should avoid when developing a loan lending app, as well as some actionable tips that might help you along the way.

Authentication & Authorization

First, you need to set up an appropriate authorization and authentication process. The best bet is to combine OAuth 2.0, the industry-standard protocol for authorization, with a proper authentication method, such as 2FA.

2FA stands for two-factor authentication and requires users to provide two different authenticators to verify themselves. Typically, the combination of authenticators includes login credentials and either a one-time password (OTP) received via SMS or biometric verification.

• OTP is the most common authentication method, and is quite simple in both implementation and subsequent use, although it is not fully PSD2 compliant.
• Biometric verification relies on users’ unique biological characteristics and is typically performed by scanning the retina or fingerprint. This option is easy to use and is highly appreciated by users.

Industry best practices also include data encryption and clearance upon user request, not to mention adhering to security standards and complying with industry and government regulations, which is a must for fintechs.

Note that any personally identifiable information (PII) you collect must be encrypted in transit and at rest. Encryption in transit means that data is encrypted before transmission and decrypted & verified upon arrival. Encryption at rest protects stored data from system compromise or data exfiltration. The encryption method depends on the cloud provider you choose to host your solution.


We recommend that you collect as much user data as possible, even if you’re not going to use it later for KYC or scoring, as it is the biggest source of actionable insights about your audience. Data provides a comprehensive overview of users, allowing you to better understand their needs, make targeted offers, and deliver a personalized experience. The data collected at this stage can also be used for underwriting or behavioral scoring.

You can collect data provided by the users themselves, or enable your solution to collect additional data, such as the user’s location, smartphone model and operating system, installed apps, etc. Knowing these details, it is easy to find out the price of the user’s device and its release date, thus determining the user’s ability to pay. Moreover, access to user data enables the creation of more detailed user personas, which is crucial for product promotion and CX strategy.

The biggest stumbling block in this step is the country-specific requirements for data sovereignty. Some countries, such as China, Germany, France, Indonesia, and others, have a law that says data is subject to the laws of the country where it is collected and must be stored on servers within the country’s borders. So you need to find out if this law applies to your target country. If it does, you can not host your solution in a cloud and it’s advisable to set up on-premise servers in advance.


In general, you can implement any KYC (or KYB, if you are creating enterprise digital lending) solution. The key point, however, is that you most likely have a bank partner that will provide banking services to your app users, including account opening, money transfer, and so on. Each traditional bank has its own compliance policies and specific requirements for customers. The KYC provider selected for implementation should adhere to these policies and meet the bank’s requirements.

Therefore, we strongly recommend that you discuss this point with your bank partner. They can either specify certain requirements for the KYC providers and the user verification process and leave the further selection to you, or provide a list of appropriate KYC services.

As for the KYC process itself, there are three options:

  1. The most straightforward way is to select a third-party service that can be quickly and easily integrated into your solution, e.g., Jumio, Veriff, ShuftiPro. These services don’t allow customizing the user verification rules, you can only set up the color scheme and UI.
    The biggest advantage of such third parties is that they can be integrated very quickly and without much effort, however, they’re quite expensive – verifying a user through these services costs about $5. As your user base grows, so will your bills for KYC service.
  2. A slightly more advanced option is to integrate services like Acuant and Alloy, which allow you to configure verification rules – e.g., you can set specific criteria to filter out unwanted users more efficiently. While these services are more expensive to implement, they offer lower per-user verification costs. In this case, you’ll also need to hire a compliance officer to set up your verification flow, adjust it during the alpha and beta testing phases, and evaluate its efficiency.
  3. You can also implement a custom KYC solution using the same data providers as the aforementioned third parties. This option can significantly reduce the cost of per-user verification. However, we recommend postponing the implementation of a custom KYC solution and focusing on core functionality to speed time to market. Besides, you can always switch from a third-party KYC service to a custom solution later.

Loan Issuing & Disbursements

There are three ways to deliver the issued credit to a borrower, each with its specifics.

• Opening a bank account. This is the most common option, but not the best. Being a traditional banking tool, opening an account is quite inconvenient for users – they cannot use it to pay for goods right away, and ACH transfers take up to several business days. Therefore, cards are usually issued in addition to a bank account.
• Issuing cards. The most advantageous option is issuing virtual cards that users can link to their digital wallets. Issuing a physical card is more expensive because you have to pay for the printing and delivery of the card, as well as for additional services such as setting up a PIN code and velocity rules, reissuing the card if it is lost or damaged, etc.
• Another option that has gained popularity in recent years is to enable users to spend credits on goods or services within a particular e-store or marketplace. This is a good opportunity for e-commerce platforms to offer their customers a wider choice of payment instruments.


Domestic and international wire transfers are the traditional method for repaying loans in the United States. However, they are not very convenient because they are lengthy and do not provide a way to track payment status. Also, there are charges associated with a wire transfer, and it is expensive to process an alternative scenario if the money is lost during the transfer or if the payment was initiated but the required amount was not in the bank account at the time of settlement (e.g., in the case of autopay ).

Another option is card payments. These are instant, but more expensive, as the card transfer fee includes a commission of about 3%, which is charged by the banks and card providers (Visa & MasterCard).

We also recommend integrating a third-party service to verify that the user initiating a transfer from an account is also the owner of that account. This is crucial because account numbers are not private and anyone can access them. Therefore, to protect users and their money, it is advisable to integrate a special service to verify account ownership. Plaid and MX are used for this purpose in America and Canada, and Aiia is popular in Europe.

Credit Scoring

Efficient scoring is crucial for digital lending because it enables data-driven decision making on granting loans and eliminates the risk of non-payment. In a nutshell, you can either integrate a pre-built scoring model from Experian or a similar service, which is fast but quite expensive, or implement a custom scoring solution. Let’s take a closer look at the latter.

• With custom rule-based scoring, you set up rules based on desired or undesired borrower characteristics. Each rule assigns a set amount of points to a borrower. When a borrower reaches the required score, he or she is approved for lending. This solution is cheaper and faster to implement.
• The other option is the ML engine, which is more expensive and takes more time to implement. However, it is far more flexible as it allows to evaluate the borrower’s creditworthiness not only based on a set of predefined attributes, but also on the borrower’s behavior within the lending app. Note that to build an efficient scoring model, the ML engine requires a large amount of data. So, you need to obtain a database for your engine to analyze and build a model that will define borrowers’ creditworthiness. If you are considering implementing ML scoring, a good option is to start with rule-based scoring, collect a suitable data set, and then use it to train the ML scoring model.

Loan Management Module

The traditional loan management process is meticulous and time-consuming and requires collecting and verifying information about applicants, their trustworthiness, and their credibility. Further, the process involves calculating interest rates and supervising payments. A loan servicing software not only automates these procedures but also provides useful analytics and insights for lenders and borrowers.

For the initial stages of your product, it makes sense not to implement it from scratch but to choose services from the market, for example, Canopy.

Integrations to Build a Money Lending App

Now that you know how to build a loan app, let’s explore some third-party that would help you speed up the loan lending mobile app development process by quickly adding features and tools to your app that might take many months to develop from scratch. Integrations also help ensure a seamless and consistent digital experience for your users. Below, we have listed the top integrations that will make your lending app more useful to users and allow you to save development time and money.

Payment Gateways

Payment gateways serve as a channel for making and receiving payments and ensure a smooth payment process by securely validating the customer’s card details and guaranteeing the availability of funds. They encrypt sensitive credit card data, ensuring secure transmission of information. When selecting a payment gateway for your lending app, consider the following: integration opportunities, accepted transactions, payment processing fees, security and fraud protection, and availability in your target region. The most popular payment gateways for lending solutions are Stripe, PayPal, Marqeta, and MangoPay.

Financial Data Aggregators

Data aggregators pool customers’ personal and financial data from a variety of sources and make it easily and conveniently accessible in a single place. This information is a great source of actionable insights that you can use to provide a more personalized experience for your customers or offer new financial products based on data-driven decisions. For a lending app, consider the following bank data aggregators: Plaid, Truelayer, Yodlee.

KYC Providers

KYC is a mandatory customer identification and verification process that financial institutions use to ensure that their customers are who they say they are. AML is a set of regulations, laws, and procedures that prevent criminals from disguising illicit funds as legitimate income. AML requires financial institutions to collect customer data, monitor and audit their transactions, and report suspicious activity to financial regulators.

Fintechs are required by law to implement these two procedures to reduce the risk of being used as a vehicle for financial crime. There are several KYC/AML providers in the market that help fintechs comply with regulatory requirements, these are the most prominent: Jumio, Alloy, Shufti Pro.

Communication Services

These help fintechs stay in touch with their customers and provide a better customer experience by streamlining communication. There are many solutions on the market – you can consider Twilio, Plivo, or others.

Digital Credit Scoring Providers

Credit scoring providers help make better lending decisions. They scan data about users collected by credit bureaus. Based on this data, the provider creates a credit history of the user that includes public records and account openings. The user is then given a score, which you can use to assess how likely they are to repay their loan. As a top credit scoring provider for your lending app, we recommend Experian.

E-Signature Providers

When it comes to digital lending, the first thing that comes to mind is a great customer experience. Then it’s only logical that when users need to sign a document, they expect to be able to do so directly in the lending app. This is where eSign providers come in. These services enable certified online delivery, acknowledgment, electronic signature, and storage of eDocuments over the Internet, allowing users to sign loan agreements and other documents. There are many solutions on the market that offer eSignature, but DocuSign is the most popular.

Loan Lending App Development Cost

The final cost of developing a money lending app depends on several factors, such as the overall complexity of the solution, the features required, the tech stack, the hourly rate of the developers, the composition of the team, etc. In this part, we will go over the key points that make up the final price of the app. All cost estimates are in working hours for simplicity. However, you can calculate the final loan lending app development cost by multiplying the figures by your developer’s hourly rate, which is on average between $35 and $50.

Discovery phase

Your team will conduct a thorough study of the money lending app market and create clear documentation, an accurate project estimate, and a well-rounded plan for further loan lending mobile app development. In addition to all the necessary deliverables, you will receive a clickable UI/UX prototype of the future app.

The discovery phase can take between 150 and 200 hours, depending on the depth of the research and the level of detail provided in the documentation.

Development phase

The length of this phase depends on whether you want to develop an MVP or a fully functional product. Your lending app MVP will include the following features:

• sign up & sign in, 2FA
• credit scoring module
• loan application
• loan origination
• linking a card to the account
• notifications

The MVP may also include some integrations – for example, a credit scoring provider and a payment gateway. This feature set is sufficient to test the initial assumptions on early adopters, get feedback from them, and optimize the product.

loan lending app development cost

If you want to develop a final product, the numbers will differ. To the listed features, the team will add the following:

• an advanced scoring module
• KYC and security modules
• additional data sources for accessing bank accounts and transaction data
• an automated module for bad deal management
• in-app chat and chatbots, etc.

Adding each new feature requires additional working hours. Taking into account the above points, the development of a functional money lending app in the basic version without advanced features takes about 3000 – 3700 hours. Given that the hourly rate of a fintech developer starts at $35, it comes to an estimated amount of about $105,000 to get started.

But that’s not the final loan lending app development cost. We haven’t factored in the full design, testing, and launch. Also, your app should have ongoing support and maintenance after launch, so those costs should be considered as well.

If you’re an early-stage startup, consider these things before the development phase

We recommend considering the points listed below for startups looking at how to start a loan app.

things to consider before the development phase

✔️ Register legal entity

Before you register your legal entity, you need to decide which legal form is best for your business. Small businesses and startups usually register as an LLC (limited liability company) or a corporation. These forms differ in the way profits and losses are distributed:

• in an LLC, profits and losses are distributed according to the agreement;
• in a corporation, profits and losses distribution depends on the ownership shares of each member. A corporation also brings with it more tax reporting and accounting requirements.

✔️ Register a business name

The name should be new, unique, memorable, and free. If you are registering the name in the United States, you can check the availability of the name here.

Note that your business name does not necessarily have to be identical to your domain name. The main difference between the two is that the former is used for identification, branding, and legal purposes, while the latter is primarily a digital address for your website. It is advisable to make your domain name short & catchy.

✔️ Raise initial capital

There are several ways to raise money for a startup:

• Get VC funding. To get venture capital from investors, you should provide them with a detailed business plan and pitch deck. If you have attracted investors’ interest, you will get money, but keep in mind that depending on the agreement, investors will receive shares in your project or you will have to pay a fixed amount. If you have no idea where to start, you can consider raising the funds for your startup in partnership with a software development company.
• Initial Coin Offering. In an ICO, a limited amount of tokens are issued and sold to investors.
• Take out a bank loan. This is not the most common option, but it certainly has a right to exist. Before taking out a loan, check all bank offers and choose the most favorable one.

✔️ Hire a lawyer & a financial specialist

Depending on your needs, you can either engage a seasoned fintech lawyer on an as-needed basis or hire a permanent in-house legal counsel. Either way, it’s always a good idea to have a reliable and experienced specialist to help you out of many a tight spot, because as a fintech startup, you’ll face a wide range of legal issues – from securing funding to protecting intellectual property and understanding local market regulations, etc.

Since the financial industry is heavily regulated, consider hiring a financial specialist in addition to a lawyer. These people are responsible for keeping your policies and procedures up to date, complying with financial regulations, and managing the risks associated with lending. The perfect team member should have hands-on experience working in the lending sector, preferably in a bank.

✔️ Find a bank partner

You’ll need to keep your money and that of investors and users somewhere, so decide on a bank partner. This cooperation will help you in the future to solve many problems related to the introduction of new loan products. However, you aren’t limited to working with just one bank – there are new offers all the time, so check the updates regularly to make sure you get the most favorable terms.

✔️ Outline loan agreement

This document has two main functions: it helps your users become familiar with the terms of the loan, and it ensures that both parties are on the same page regarding the loan and repayment process, which allows you to align expectations and avoid problems in the future. Therefore, you should make sure that your loan agreement is properly drafted.

✔️ Consider local regulations

Depending on your target market, you’ll have to comply with local regulations, which vary from region to region. For example, if you are targeting the European market, your app must be GDPR compliant, and for apps for California, CCPA compliance is a must.
