developing a Sezzle-like BNPL app presents a strategic opportunity. This blog provides all the information needed to develop a BNPL app like Sezzle so you can tap into a demographic eager for transparent and flexible payment solutions.

What Is A Sezzle App?

Sezzle is a digital payment solution that allows users to purchase items online and split the total cost into four interest-free payments over six weeks. This helps users manage their expenses without extra fees. This app also offers a transparent and convenient alternative to traditional credit. Utilizing advanced risk assessment technology, Sezzle provides quick and equitable credit approvals while extending financial access to more users.

Partnering with over 40,000 merchants, Sezzle helps businesses boost sales, increase basket sizes, and improve conversion rates. By taking on the credit risk, they enable retailers to reach a wider audience and grow their business. With over 2.9 million active users, Sezzle is highly rated on Trustpilot for its user-friendly approach and dedication to customer satisfaction, making it a preferred payment choice for today’s consumers.

How Does The Sezzle App Work For Users?

Here is a detailed scope to understand Sezzle’s user-friendly payment method:

• Sezzle simplifies payments with a straightforward approach: users pay 25% upfront at checkout, followed by three equal installments every two weeks. This spreads the purchase over six weeks, without accruing interest or additional fees for on-time payments.
• Users can choose from several payment methods customized to their preferences. Automatic ACH transfers ensure fee-free transactions directly from their bank accounts. Alternatively, payments can be made via prepaid, credit, or debit cards, with a $5 fee per transaction.
• Maintaining account activity requires timely payments. A late payment of two days leads to temporary account deactivation until the overdue amount, plus a $15 reactivation fee, is settled.
• Sezzle sets individual spending limits, with transparency varying. Users can discover their limits by setting up ACH transfers as their default method or through the app, especially when upgrading to Sezzle Up.
• Users can enhance their benefits by upgrading to Sezzle Up, which includes credit bureau reporting upon:

• Identity verification, including Social Security number
• Defaulting to ACH transfers or debit cards
• Successful repayment of a Sezzle loan

• There are beta upgrades such as Sezzle Premium that offers expanded merchant access, exclusive deals, and priority customer support. Users can also earn rewards through Sezzle Rewards by accumulating points with select merchants for future discounts.
• For single-payment purchases, Sezzle Pay-in-Full allows users to earn rewards while building a positive repayment history.
• Sezzle simplifies payment flexibility, ensuring a seamless shopping experience with transparent terms and valuable upgrades. Discover how Sezzle can streamline your transactions today.

How Does The Sezzle App Work On The Backend?

Sezzle operates as a Buy Now, Pay Later (BNPL) service, using a robust API to enable smooth transactions between consumers and merchants. Here’s a breakdown of how Sezzle functions in the backend:

1. Merchants integrate Sezzle’s API into their e-commerce platforms. This integration allows the merchant’s system to interact directly with Sezzle.
2. When a shopper chooses Sezzle at checkout, the merchant’s system sends a request to Sezzle’s API with details about the purchase, such as the amount and items bought.
3. Sezzle’s system reviews the request and decides whether to approve the payment plan. This decision is based on the shopper’s account history and other factors. If approved, Sezzle provides a payment plan and a link to the Sezzle checkout page.
4. The shopper is redirected to the Sezzle checkout page to complete the payment. Once done, they are directed back to the merchant’s website, confirming the transaction.
5. After the payment is completed, the merchant’s system sends a request to Sezzle’s API to finalize the payment. Sezzle processes this request and sends a confirmation back to the merchant.
6. For users enrolled in the Sezzle Up program, Sezzle reports payment activity to major credit bureaus. This helps users build or improve their credit history.

Sezzle’s backend operations are designed to optimize user experience, ensure transaction security, and boost financial growth—a pivotal element for enhancing customer satisfaction and driving business success.

Market Stats Of Buy Now Pay Later Services

In 2023, the global Buy Now, Pay Later (BNPL) market was valued at USD 30.38 billion. It is projected to increase from USD 37.19 billion in 2024 to USD 167.58 billion by 2032, with an annual growth rate of 20.7% during this period.

Another report predicts that the global BNPL market size will grow at a compound annual growth rate of 26.1% from 2023 to 2030. This growth is mainly driven by consumers’ preference for flexible and convenient payment methods. BNPL services allow customers to make purchases without paying immediately, providing financial flexibility and reducing the burden of upfront costs.

The increase in e-commerce has also significantly contributed to the BNPL market’s expansion. As online shopping becomes more widespread, consumers seek seamless and efficient payment options. BNPL services integrate smoothly with online checkout processes, offering a quick and hassle-free payment experience. The growth of e-commerce platforms and the adoption of digital wallets have made BNPL solutions attractive to both consumers and merchants.

Why Should Businesses Invest In Developing A BNPL App Like Sezzle?

Investing in a Buy Now, Pay Later (BNPL) app like Sezzle can greatly enhance a business’s sales and customer satisfaction. Here are the key reasons why developing a BNPL app is beneficial:

1. Increase Sales:

A BNPL app can significantly boost sales. By allowing customers to pay in installments, businesses make expensive items more affordable. This encourages customers to make larger purchases and attracts those who might otherwise be hesitant.

2. Improve Conversion Rates:

High upfront costs often lead to cart abandonment in online shopping. A BNPL option addresses this issue by breaking down the total cost into smaller, manageable payments. This makes it easier for customers to complete their purchases, leading to higher conversion rates.

3. Attract And Retain Customers:

BNPL apps are appealing to both new and existing customers. New customers may choose your business over competitors due to the flexible payment options. Existing customers are more likely to return if they have a positive experience with your BNPL service. This helps acquire new customers and retain loyal ones.

4. Immediate Cash Flow:

Using a BNPL service like Sezzle ensures immediate payment to the business. When a customer opts for BNPL, the business receives the full payment upfront from the BNPL provider. This eliminates cash flow issues and reduces financial risks. The BNPL provider collects payments from the customer.

5. Competitive Advantage:

Offering BNPL can give your business a competitive edge. In the crowded e-commerce market, consumers often compare different sites before making a purchase. A BNPL option can be a deciding factor in attracting more customers and improving your market position.

Essential Features To Build An App Like Sezzle

Creating a Buy Now, Pay Later (BNPL) app like Sezzle involves incorporating several essential features:

1. User Registration And Authentication: 

Identifying and verifying users is essential. This usually involves collecting basic details (such as name, email, and phone number) and setting up secure login credentials.

2. Credit Check And Approval System: 

A BNPL app needs a system to evaluate a user’s creditworthiness and approve their financing. This may involve integrating with credit scoring APIs or using proprietary algorithms.

3. Payment Processing: 

The app must handle user payments and transfer funds to merchants. This requires integration with payment gateways and potentially banking APIs.

4. Installment Management: 

The app should allow users to view their installment plans, track payment schedules, and make payments. It should also send reminders for upcoming payments.

5. Merchant Integration: 

The app needs to connect with merchant platforms to be offered as a payment option at checkout. This might involve developing plugins or APIs for popular e-commerce platforms.

6. Customer Support: 

Handling customer inquiries and resolving issues is crucial. This could include a chatbot, a support ticket system, or integration with a customer service platform.

7. Regulatory Compliance: 

Depending on the region, BNPL providers must comply with financial regulations. This involves implementing data security measures, protecting user privacy, and adhering to lending laws.

8. User Interface (UI) And User Experience (UX): 

A user-friendly design is vital. The UI should be intuitive, and the UX should be smooth, ensuring users can easily navigate the app and complete their tasks.

9. Analytics And Reporting: 

These tools provide insights into user behavior, transaction trends, and app performance. They help in making data-driven decisions to improve and grow the business.

10. Flexible Payment Rescheduling: 

This feature allows users to manage their finances more effectively by adjusting payment dates to better align with their cash flow. Offering free rescheduling options can improve user satisfaction, reduce the likelihood of missed payments, and demonstrate your commitment to user convenience. Automated reminders and an intuitive interface for rescheduling can further enhance this feature’s effectiveness.

Five Advanced Features To Consider While Building An App Like Sezzle

When developing a Buy Now, Pay Later (BNPL) app similar to Sezzle, incorporating advanced features can significantly enhance its appeal and functionality. Below are five key features that can set your app apart and provide substantial value to your users:

1. Credit Building Feature: 

One standout feature of Sezzle is “Sezzle Up,” which allows users to build their credit scores through their BNPL transactions. Implementing a similar feature can attract users who are keen to improve their creditworthiness. This involves reporting timely payments to credit bureaus, thereby helping users establish or boost their credit scores. 

2. Subscription-based Premium Services: 

Introducing a premium subscription like “Sezzle Premium” can provide users with exclusive benefits. This could include access to a wider range of merchants, special deals, rewards, and priority customer support. Offering a tiered service model can enhance user engagement, encourage loyalty, and create an additional revenue stream for your business.

3. Rewards And Loyalty Programs: 

A rewards system can incentivize users to make more purchases. Implement a feature where users earn points for every dollar spent with partnered merchants. These points can be redeemed for discounts, future purchases, or other rewards. This not only boosts user activity but also strengthens partnerships with merchants.

4. Flexible Payment Options: 

Allowing users to reschedule their payments without incurring fees can be a valuable feature. This flexibility helps users manage their finances more effectively and reduces the likelihood of missed payments. Implementing automated reminders and an easy-to-use interface for rescheduling payments can improve user satisfaction and retention.

5. Integration With Google Pay And Apple Pay: 

Enhancing your app with support for popular digital wallets like Google Pay and Apple Pay can provide users with more payment options and a seamless checkout experience. This integration can simplify the payment process, increase security, and cater to the preferences of tech-savvy users who prefer using digital wallets.

Other Technical Implementation And Considerations

1. Credit reporting integration: Partner with major credit bureaus to report user payment activities. Ensure compliance with data protection regulations and maintain transparency with users about how their data is used.
2. Subscription service management: Develop a subscription management system that can handle different tiers of service, billing cycles, and exclusive content or services. Ensure that the system is scalable to accommodate growing user bases.
3. Rewards program algorithm: Create a backend system to track user purchases, calculate reward points, and manage redemption processes. Ensure the system is secure and can handle high volumes of transactions without performance issues.
4. Payment flexibility features: Implement a user-friendly interface that allows users to reschedule payments easily. Integrate this with your billing system to automatically adjust payment schedules and send timely reminders.
5. Digital wallet integration: Use APIs provided by Google Pay and Apple Pay for seamless integration. Ensure that your app meets all security standards required by these platforms to protect user payment information.

How To Develop A BNPL App Like Sezzle: A Step-By-Step Guide?

Here are the detailed technical steps required for the development of a Buy Now Pay Later app like Sezzle:

1. Understanding The BNPL Market: 

Start by analyzing the BNPL market to identify the needs of your potential users and the offerings of your competitors. Examine the demographics, income levels, and spending habits of your target audience. Study competitors’ features, pricing strategies, and customer feedback. Additionally, stay updated on emerging trends in e-commerce and fintech, especially those relevant to BNPL services. Use tools like Google Trends, SEMrush, and industry reports for market analysis. You can also conduct surveys and focus on groups to gather qualitative data.

2. Define The Project Scope:

Based on your market research, outline the scope of your project. Clearly define your target audience and their needs related to installment payments and financial flexibility. Determine the essential features and functionalities your BNPL app will offer to meet these needs effectively. Create detailed project documentation, including a Product Requirements Document (PRD) and a Software Requirements Specification (SRS).

3. Assemble A Development Team:

Gather a skilled programming team that includes frontend and backend developers, UX/UI designers, project managers, and quality assurance specialists. Ensure the team has a well-established development process and effective communication channels.

4. Design User Experience (UX):

Develop wireframes, mockups, and prototypes for your BNPL app. Focus on designing an intuitive and simple user interface that enhances the user experience, especially for installment payment tracking and management. Moreover, usability testing should be conducted to identify pain points and ensure smooth navigation and user satisfaction. Use Sketch, Figma, or Adobe XD for design. Conduct A/B testing and usability testing with tools like UserTesting or Optimal Workshop.

5. Implement Identity Verification:

Integrate an identity verification system to ensure the authenticity of your users. You can achieve this by partnering with third-party identity verification services or developing an in-house system to verify user identities securely, which is crucial for BNPL services to manage risk. For technical implementation, you can use third-party services like Jumio, Onfido, or ID.me. Moreover, you can implement multi-factor authentication (MFA) and secure login mechanisms (OAuth 2.0).

6. Develop Backend Services:

Create backend services for account management and payment processing specific to transactions from the BNPL model. This involves setting up databases, developing APIs, and implementing the necessary business logic to support your app’s functionality. Here, you can use RESTful or GraphQL APIs for communication, implement microservices architecture for scalability, and ensure data encryption (AES-256) and secure data transmission (HTTPS, TLS).

7. Build The Frontend:

Code the frontend components based on the UX design. Ensure seamless integration with backend services and optimize the app for performance across various devices, providing a consistent user experience. You can optimize for performance using techniques like lazy loading and code splitting. Moreover, you can ensure responsive design for different screen sizes and devices.

8. Integrate Third-party APIs:

Integrate with third-party APIs for payment gateways and fraud prevention. Consider using services like Stripe for secure payment processing and Sift for advanced fraud detection and prevention. For this you must use APIs provided by payment gateways like Stripe, PayPal, or Square. Moreover, you can implement fraud detection with APIs from Sift, Riskified, or Kount.

9. Ensure Regulatory Compliance:

Verify that your app complies with all relevant financial regulations. Implement data security measures and user privacy protections and ensure adherence to lending laws to avoid legal issues and build user trust. Ensure GDPR, CCPA, and PCI-DSS compliance and implement secure data storage and regular audits for compliance.

10. Testing And Deployment: 

Perform comprehensive testing to ensure security and functionality. Conduct user acceptance testing (UAT) with a diverse group of users to validate that the app meets user needs and expectations.

Once testing is complete and any issues have been resolved, proceed with deployment. Set up hosting, configure servers, and monitor app performance to ensure a smooth launch and operation. Use CI/CD pipelines for automated deployment (Jenkins, CircleCI, GitHub Actions) and set up monitoring with tools like New Relic, Datadog, or Prometheus. Apart from this, you must perform regular updates and maintenance.

5 Popular BNPL Apps Like Sezzle

1. Splitit

Splitit is a unique Buy Now, Pay Later (BNPL) service that allows users to divide payments using their current credit cards. It imposes no extra charges, applications, or credit verifications, appealing to responsible credit card users avoiding new loans.

2. Zip

Zip ranks first in PYMNTS’ BNPL Provider Rankings. Despite charging installment fees for its Pay-in-4 loans, Zip’s popularity can be attributed to its acceptance by over 80,000 merchants. The ‘Zip Anywhere’ feature also allows users to make purchases at merchants that don’t explicitly offer ‘Buy with Zip.’ Installment fees are $4 for purchases up to $99.99, $5 for purchases up to $199.99, and $6 for purchases of $200 or more.

3. Klarna 

With around 20,000 partner stores in the US, Klarna may not have the broadest reach, but it compensates with a one-time virtual card service similar to Zip’s. Klarna’s main strength is its interest-free Pay-in-4 and Pay-in-30 days options, both free of fees if payments are made on time. However, a late fee of up to $7 is charged for missed payments beyond ten days, which is considerably lower than Sezzle’s maximum late fee of $15.

4. Afterpay 

Having been available in the US since 2018, Afterpay distinguishes itself with a financial hardship policy. It offers the same 0% interest Pay-in-4 loans as Klarna and Apple Pay Later. While its monthly plan APR is slightly higher than Sezzle’s, Afterpay’s maximum late fee is only $8.

5. Affirm 

Affirm is notable for not charging late fees, claiming to have saved users $231 million in late fees from July 2016 to June 2023. Its Pay-in-4 loans are free from interest and fees, making them essentially risk-free. Affirm also ensures that using its pay-in-4 option won’t impact your credit score. However, while Affirm’s monthly payment plans can have a higher maximum APR than Sezzle, they can also offer 0% APR for users with excellent credit.

Cost To Build An App Like Sezzle
