As organizations look for better ways to manage healthcare costs without reducing employee benefits, HSA platforms have become a key part of modern healthcare. What started as a tax-saving account has evolved into a smarter way for people to pay for medical expenses while building long-term savings. The growing popularity of HSA platforms is driven by rising healthcare costs and the increasing adoption of high-deductible health plans. Both employers and employees now see HSAs as more than just a savings account. They have become an important financial benefit that offers greater flexibility, tax advantages, and long-term value.

We’ve developed several HSA solutions that leverage secure banking API integrations and automated IRS compliance engines to simplify healthcare savings management for employers, administrators, and account holders. Drawing on this experience, we’re writing this blog to explain what it takes to build an HSA platform like HealthEquity, covering the key technologies and development considerations behind a secure, scalable solution.

The Market Size of Health Savings Accounts

According to Data Insights Market, the Health Savings Account provider market is projected to reach around $55 billion by 2025 and is expected to grow at a 12.5% CAGR through 2033. This steady growth is driven by rising healthcare costs and the growing use of HSAs as long-term financial tools rather than simple medical savings accounts. For businesses, this creates an opportunity to build platforms that combine healthcare payments, investment management, and secure financial services into a single user experience.

HSA Assets Reach Record Highs

One of the biggest reasons HSA platforms have become attractive businesses is the steady growth of assets held within them. As users keep their funds invested over the long term, platforms generate recurring revenue while managing larger pools of capital. HealthEquity is a strong example of this model, reporting $1.31 billion in annual revenue while managing more than $36 billion in HSA assets. It shows how a well-designed HSA platform can scale into a highly profitable healthcare fintech business. 

For an investor, this sustained asset growth offers clear advantages:

• Predictable Revenue: Larger asset pools yield higher, more stable custodial fees.
• Interchange Income: Increased balances lead to more frequent card transactions, driving steady payment processing revenue.
• Scale Efficiencies: As the total capital on your platform grows, your marginal cost to support each dollar drops significantly.

Employer Adoption Fuels Expansion

Corporate America is actively driving the expansion of the HSA market. Companies are shifting away from traditional plans and toward High-Deductible Health Plans paired with HSAs. Employers prefer this setup because it lowers their premium obligations and reduces their overall payroll tax burden.

To sweeten the deal for workers, many corporations now seed these accounts with direct contributions. This institutional backing ensures a steady, automated influx of capital into the ecosystem every single month. A modern HSA platform that integrates smoothly with enterprise HR software can capture these corporate fund flows right at the source, securing a defensive and loyal B2B user base.

Investment HSAs Create New Revenue

Many HSA users now view their accounts as long-term investment tools instead of using them only for everyday medical expenses. This shift is creating new opportunities for platforms that offer investment features alongside healthcare savings. Lively is a good example of this approach, managing more than $2 billion in assets under management and achieving an impressive 2,380% three-year revenue growth. It highlights how investment-focused HSA platforms can drive stronger user retention and unlock significant long-term business growth. 

How HealthEquity Built the Largest HSA Ecosystem?

HealthEquity started as a pioneer in consumer-driven healthcare and scaled into a dominant financial force. The platform operates as a massive custodian connecting millions of health savings accounts with enterprise employers. By aligning corporate cost savings with consumer wealth accumulation, the company created a blueprint for healthcare fintech monetization.

The platform generated an annual revenue of $1.31 billion, showcasing the immense profit potential available to institutional software. This top-line revenue is supported by three pillars: custodial fees from cash balances, recurring software fees from employer networks, and interchange revenue from card transactions.

Millions of Members and Billions in Assets

Scaling an HSA platform requires far more than acquiring new users. Success depends on building an infrastructure that can securely manage millions of accounts while meeting strict financial and healthcare regulations. HealthEquity demonstrates this at scale, serving over 10.6 million HSA accounts and managing approximately $36.5 billion in HSA assets. Its growth also shows the importance of early investment, as venture funding helped build the technology and operational foundation needed to support long-term expansion. 

Connected Employer and Benefits Networks

The core engine behind long-term retention is enterprise integration. HealthEquity expanded far beyond individual users by deeply embedding its software into corporate benefits systems. The architecture connects directly with employers, health insurance plans, and payroll networks to capture funds automatically.

• Integrated Benefits Ecosystem: The system manages FSAs, HRAs, and COBRA compliance alongside core HSA products.
• Sticky B2B Moats: Once an enterprise configures its HR systems to a platform, switching costs become painfully high.
• Predictable Recurring Revenue: Institutional automated payroll deductions create an uninterrupted pipeline of incoming deposits.

By consolidating these disparate benefits under a single dashboard, the platform solves an administrative headache for corporate HR teams. This ecosystem strategy shifts the product from an optional perk to an essential piece of corporate infrastructure.

Growth via Innovation and Acquisitions

Continuous product evolution is mandatory to defend market leadership. HealthEquity maintains its edge by offering advanced investment workflows, automated mutual fund trading, and a streamlined mobile interface. These technical capabilities attract high-balance savers who maximize their investment returns.

Organic product development is accelerated through bold portfolio acquisitions. A major milestone includes the buyout of the BenefitWallet HSA portfolio for $425 million. This single transaction transferred 616,000 accounts and $2.7 billion in active assets directly onto the HealthEquity platform.

Products and Services Offered by HealthEquity

HealthEquity’s success comes from offering a complete benefits ecosystem instead of a single HSA product. Along with Health Savings Accounts, the platform supports other tax-advantaged benefit accounts, allowing employers to manage multiple programs through one solution. This approach increases customer retention, creates additional revenue opportunities, and makes the platform more valuable for enterprise clients looking for an all-in-one benefits management system.

1. HSA and Investment Solutions

The foundational core of the platform is the pre-tax Health Savings Account. The system allows users to deposit pre-tax funds, pay for qualified medical bills, and invest their unused cash. The platform lowers the barrier to entry by enabling automated investments once a user crosses a minimum cash threshold, which is typically set at $2,000. 

Once a user crosses this cash threshold, the platform unlocks access to mutual funds and institutional investment options. This dual cash-and-investment structure creates two distinct revenue models for the business:

• Cash Interest Spreads: The platform earns interest on the base cash balances held in depository partner banks.
• Investment Management Fees: The system captures assets under management fees as users build long-term investment portfolios.

2. Flexible Reimbursement Accounts

To capture users who do not qualify for an HSA, the platform provides a full suite of reimbursement accounts. This includes Healthcare FSAs, Dependent Care FSAs, Limited Purpose FSAs, and Health Reimbursement Arrangements (HRAs). Managing these varied fund pools requires a flexible ledger architecture that can track distinct expiration dates and compliance rules.

All these accounts run on a unified backend infrastructure. Employees use a single payment card that automatically pulls funds from the correct account based on the transaction type, creating a frictionless user experience.

3. COBRA and Commuter Benefits

Enterprise clients require help navigating complex federal compliance mandates. The platform solves this by automating COBRA continuation coverage and premium collection when employees leave a company. This regulatory automation shifts the operational burden away from the employer’s internal human resources team.

The software also manages pre-tax commuter benefits for parking and public transit. This feature leverages mobile-first digital enrollment to allow employees to adjust their monthly travel budgets on the fly. By bundling these compliance-heavy services, the platform protects itself from churn, as companies rarely dismantle systems that handle federal compliance.

4. Employer Platforms and Member Services

The true strength of the platform lies in its deep operational connectivity. The software integrates directly with over 100 payroll systems and major health insurance plans. This connectivity allows the system to process files, update coverage status, and sync employee rosters without human intervention.

On the user side, the platform delivers a modern mobile app alongside automated claims processing systems. This consumer software layer handles real-time digital reimbursements, receipt uploading, and financial wellness tracking. Providing this comprehensive support framework allows the platform to maintain its position as an industry leader.

Key Features of an HSA Platform Like HealthEquity

A successful HSA platform is built around simplicity, even though the technology behind it is highly complex. Users expect to manage contributions, pay medical expenses, track investments, and access tax documents without switching between multiple systems. At the same time, employers need reliable tools to administer benefits and stay compliant, making a seamless experience for both groups essential to the platform’s success.

1. Secure Account Onboarding

HealthEquity makes getting started simple with a fully digital onboarding experience that lets users open and activate their HSA without paperwork. After the account is created, users can manage beneficiaries, link bank accounts, automate contributions, and update account preferences from a self-service dashboard. This approach reduces support overhead while giving members greater control over their healthcare savings.

2. Payments and Smart Reimbursements

HealthEquity users manage their daily healthcare expenses through a centralized transaction hub. The platform issues a dedicated Visa debit card that pulls funds directly from the member’s HSA cash balance at the point of sale.

• Direct Provider Payments: Users swipe their card directly at pharmacies, clinics, and hospitals.
• Out-of-Pocket Reimbursements: If a user pays with personal cash, they use the dashboard to push an electronic reimbursement straight to their linked checking account.
• Linked Bank Transfers: Members can link external bank accounts to transfer money back and forth within a standard two-day settlement window.

3. Investment and Wealth Management Tools

HealthEquity goes beyond helping users save for healthcare expenses by offering built-in investment options for long-term wealth growth. Once users meet the required balance, they can invest their HSA funds in mutual funds, monitor portfolio performance, and manage their investments from the same platform. This makes the HSA more than a spending account and encourages users to treat it as part of their long-term financial planning.

4. Mobile App with Real-Time Access

The mobile application is the primary touchpoint for daily user engagement within the HealthEquity ecosystem. Members use the app to check active balances before paying for care, ensuring they have sufficient funds available. The app uses push notifications to alert users the moment a transaction occurs. If an unexpected medical bill arrives, users can take a photo of the invoice, submit a claim, and track the approval status directly from their smartphone screen.

5. Employer Admin and Payroll Integration

HealthEquity is designed not only for individual account holders but also for large employers managing workforce benefits at scale. Supporting more than 100,000 corporate employers, the platform provides dedicated administrative tools for handling employee enrollments, payroll contributions, and benefit management. It also integrates with HR and payroll systems, making it easier for organizations to manage HSA programs without adding extra administrative work.

6. Claims, Receipt, and Expense Management

Tax compliance is a primary concern for HSA users, and HealthEquity addresses this with a digital document repository. Members use their mobile camera to capture images of receipts and medical invoices right at the doctor office. The system categorizes these documents and links them directly to the corresponding debit card transaction. This creates an IRS-compliant audit trail that protects the user during tax season, allowing them to archive years of medical documentation securely.

7. Alerts, Support, and Financial Insights

HealthEquity keeps users engaged by providing timely notifications and proactive account updates throughout the year. The platform alerts users about important milestones, such as approaching HSA contribution limits, helping them avoid unnecessary tax issues. When users need assistance, they can access live chat or 24/7 customer support, giving them quick access to help without disrupting their healthcare savings experience.

How to Build an HSA Platform Like HealthEquity?

Creating a successful HSA platform takes more than strong technical development. We combine secure fintech infrastructure with healthcare compliance and scalable cloud architecture to build platforms that are ready for long-term growth. Our focus is on simplifying complex workflows, automating critical processes, and delivering a seamless experience for both employers and account holders. This is the approach we use to build HSA platforms that can compete with established players like HealthEquity.

1. Business Models and User Segments

Before writing a single line of code, we work with you to lock down your target audience and monetization strategy. Selecting your primary user segments dictates the entire software design, regulatory footprint, and sales pipeline. Our development strategy scales across multiple operating models:

• The Employer Channel: Targeting HR teams to capture massive blocks of employees simultaneously.
• The Institutional Channel: Partnering with regional banks, insurance providers, or Third-Party Administrators who need modern white-label software.
• The Direct Consumer Channel: Attracting affluent savers looking for superior, low-fee investment pipelines.

2. Secure Account Onboarding

A smooth onboarding experience is essential for user adoption, so we build fast and secure account setup workflows that minimize friction. By integrating identity verification, KYC, and eligibility checks directly into the registration process, we help users open HSA accounts in minutes instead of dealing with lengthy paperwork. This creates a better first impression while ensuring the platform remains secure and compliant from day one. 

3. Payroll, Banking, and Health Plan Integration

Behind every successful HSA platform is a strong integration layer. We connect the platform with payroll systems, banking networks, and insurance providers to automate contributions and keep account data synchronized across every system. This reduces manual work for employers, improves accuracy, and helps ensure contributions stay within annual IRS limits without creating extra administrative effort.

4. Payments and Investment Tools

The true value of an HSA platform lies in its transaction engine. We build robust systems that handle everyday point-of-sale spending while supporting sophisticated wealth management capabilities for long-term savers. We integrate your platform with premium card issuers to provide branded debit cards that work smoothly at physical medical terminals.

For wealth accumulation, our engineering team builds automated sweep features. When a user cash balance passes a pre-set threshold, our system pushes the excess capital directly into high-yield market funds to generate asset management fees.

5. Compliance and Enterprise-Grade Security

When dealing with healthcare data and banking assets, security is your primary product feature. We build every layer of your software following zero-trust security principles to safeguard sensitive user information.

• Data Protection: We apply AES 256-bit encryption for all data resting in databases and TLS 1.3 for all information moving across networks.
• Regulatory Frameworks: Our code architecture is built from the ground up to achieve SOC 2 Type II certification and maintain strict HIPAA compliance.
• Financial Auditing: We deploy immutable ledger tracking systems that log every balance shift, creating an ironclad audit trail for IRS reporting.

6. Employer and Member Portals

Every HSA platform serves two very different user groups, so we design separate experiences for employers and account holders. We build administrative dashboards that help HR teams manage employee benefits and contributions efficiently, while the member portal gives users an easy way to view balances, submit claims, manage investments, and track their healthcare savings from a single place.

7. Cloud-Native, API-First Architecture

Long-term scalability starts with the right architecture, which is why we build HSA platforms using a cloud-native, API-first approach. This allows the platform to handle growing user demand while making it easy to add new services as the business expands. Whether you plan to introduce FSAs, HRAs, or other employee benefits in the future, we create a flexible foundation that supports growth without requiring a complete rebuild.

Cost to Build an HSA Platform Like HealthEquity

The cost of building an HSA platform depends on the features you want to launch, the level of compliance required, and the overall complexity of the system. We follow a phased development approach that helps businesses control costs while validating the product at each stage. This allows you to launch faster, scale confidently, and invest in advanced capabilities as your platform grows. 

MVP Development Cost

Launching with an MVP is the fastest way to validate your idea and enter the market without building every feature upfront. We focus on the core functionality needed to onboard users, manage HSA accounts, and support employer contributions, creating a solid foundation for future growth. In most cases, an HSA platform MVP can be developed in 4 to 6 months, allowing businesses to gather user feedback and attract early customers or investors. 

Enterprise Features and Compliance

As your HSA platform grows, we help expand it with advanced features that support enterprise clients and long-term user engagement. At this stage, we focus on strengthening security, automating compliance, and building systems that can handle large volumes of users and transactions. This ensures the platform remains reliable, secure, and ready to scale as your business grows.

Ongoing Infrastructure and Maintenance

Building the platform is only the beginning, which is why we provide ongoing maintenance and technical support after launch. We help keep the platform secure, reliable, and up to date while monitoring performance as the user base grows. We also help businesses plan for recurring operational costs such as cloud infrastructure, software licenses, and third-party services, ensuring the platform remains stable over the long term.

• Cloud Infrastructure Hosting: Scalable cloud computing environments require roughly $2,500 to $6,000 per month depending on active database traffic.
• Banking & Verification APIs: Continuous identity checks, debit card processing networks, and brokerage connectivity run between $1,500 and $4,000 monthly.
• Engineering Updates & Audits: Quarterly software tuning, security patches, and regulatory compliance maintenance typically average $35,000 to $65,000 annually.

By budgeting for these ongoing operational costs, you ensure your software remains fast, secure, and ready for institutional enterprise adoption.

Why B2B2C Matters More Than Direct Consumer Acquisition?

A strong go-to-market strategy is just as important as building the right technology. Most successful HSA platforms grow by partnering with employers, benefits administrators, and insurance providers instead of acquiring individual users one by one. This B2B2C approach reduces customer acquisition costs, accelerates user growth, and creates a more predictable path to long-term revenue.

1. Employers Drive Faster Acquisition

The biggest advantage of the B2B2C model is that a single enterprise partnership can bring thousands of users onto the platform. Instead of spending heavily on individual customer acquisition, HSA providers grow by working with employers and benefits administrators who introduce the platform during employee enrollment. This creates a more efficient and scalable growth strategy.

WEX is a strong example of this approach. By serving employers and benefits administrators, the company generated more than $800 million in annual benefits segment revenue while supporting over 21 million accounts. It shows how enterprise partnerships can become a powerful driver of long-term growth for HSA platforms.

2. B2B2C Creates Predictable Revenue

Partnering directly with corporate employers creates highly defensive, predictable revenue streams that outperform consumer wallets. Individual retail users frequently switch financial applications based on short-term market trends. Corporate benefit implementations, by contrast, are protected by exceptionally high structural switching costs.

This corporate distribution engine is how major financial institutions lock in dominant long-term market control. Fidelity Investments harnessed its enterprise workplace relationships to grow total HSA assets to over $24 billion, managing more than 3.3 million funded accounts. Their massive asset volume is driven by capturing corporate 401k clients and cross-selling them comprehensive healthcare wealth software.

3. Integrations Strengthen the Ecosystem

Enterprise integrations are one of the biggest factors that determine the success of an HSA platform. Connecting with HRIS, payroll, and benefits systems allows employee contributions and account information to stay synchronized automatically. This reduces manual work for HR teams and improves accuracy across the platform.

These integrations also create a strong competitive advantage. Once an employer relies on a platform for payroll synchronization, contribution tracking, and benefits administration, switching to another provider becomes far more difficult. That makes enterprise connectivity a key driver of customer retention and long-term business growth.
