III. Types of FinTech Applications and Their Cost Estimates in Vietnam

The development costs of FinTech applications largely depend on the type of app you want to create. Popular FinTech app categories include banking apps, lending apps, investment apps, personal finance apps, and insurance apps. Below is an overview of these app types along with their realistic cost estimates in Vietnam, where development costs are significantly lower compared to Western markets.

Banking Apps

Banking apps allow users to handle financial services entirely online, from creating accounts to applying for loans. These apps eliminate the need for visiting physical branches and can efficiently manage various banking needs.

For instance, one of our clients, a European bank, implemented an AI-based mobile banking solution that reduced manual processes by 35% and improved customer retention by 20%. The app now handles over 50% of customer service requests through an integrated chatbot.

In Vietnam, the cost of developing a banking app ranges between $15,000 and $100,000, depending on complexity. A more streamlined alternative is a Neobank app, which operates entirely online, offering services exclusively via mobile platforms. Developing a Neobank app in Vietnam would fall within the same range depending on its features.

Lending Apps

The peer-to-peer (P2P) lending industry is rapidly growing globally and is gaining traction in Vietnam as well. These apps simplify the lending process by allowing users to apply for loans digitally, backed by AI and machine learning algorithms to verify identities, assess creditworthiness, and predict payment risks with precision.

Lending apps in Vietnam cost between $20,000 and $80,000 to develop. The cost to build a FinTech app depends on the integration of features like credit score analysis, loan tracking, and payment reminders.

Personal Finance Apps

Personal finance apps help users track their income, expenses, and budgets in real-time. These apps act as digital financial journals, enabling users to manage their finances effectively. Popular features include expense categorization, savings trackers, and financial forecasting.

In Vietnam, the cost to build a personal finance app typically ranges from $20,000 to $120,000. The final price depends on features like AI-powered budgeting tools, notifications, and multi-currency support.

Insurance Apps

The insurance sector is also undergoing a digital transformation, with FinTech apps modernizing how insurance policies are purchased, managed, and claimed. These apps offer faster claims processing, policy comparisons, and real-time updates, enhancing user experiences for both customers and agents.

In Vietnam, developing an insurance FinTech app costs around $25,000 to $100,000, depending on the complexity of features like policy management dashboards and AI-driven fraud detection systems.

Investment Apps

Investment apps give users access to tools for trading, crypto exchanges, and mutual fund investments. These apps often include features like real-time market updates, portfolio management tools, and AI-driven investment recommendations.

The cost of developing an investment app in Vietnam ranges from $30,000 to $80,000, depending on features such as data visualization, live trading capabilities, and blockchain integration.

IV. Smart Tips to Optimize FinTech App Development Costs

Developing a FinTech app doesn’t have to break the bank. Over the years, we’ve worked with numerous FinTech companies and discovered practical strategies to minimize costs while maintaining quality. Here are our top three tips to help you stay on budget:

Tip #1: Start with an MVP (Minimum Viable Product)

It’s tempting to pack your app with every feature you’ve dreamed of, but this approach can backfire. A feature-heavy app doesn’t guarantee user engagement—it might even have the opposite effect by overwhelming your users with cluttered interfaces or unstable functionality. Plus, adding extra features significantly increases development costs and timelines.

Instead, focus on building an MVP that includes only the most essential features. For example, if you’re developing a lending app, prioritize core functionality like credit scoring, loan applications, and automated repayment systems. Once your app proves successful, you can gradually introduce additional features like gamification elements or multi-currency support. This approach not only saves you money upfront but also allows you to test and refine your app based on real user feedback.

Tip #2: Outsource vs. In-House Development—Choose Strategically

When it comes to development, the choice between outsourcing and in-house teams isn’t just about cost—it’s about what aligns best with your business strategy.

In-house development gives you more direct control over the process, but it comes with long-term financial commitments, including salaries, benefits, and infrastructure. For startups or small businesses with tight budgets, these recurring expenses can be overwhelming.

Outsourcing, on the other hand, offers greater flexibility. While the initial cost may seem higher, you’re not tied to ongoing overheads once the app is launched. Plus, outsourcing allows you to focus on growing your business while the development team handles the heavy lifting. By partnering with experienced agencies, you can scale your spending based on your needs and avoid unnecessary expenses.

Tip #3: Leverage Third-Party Services

Why reinvent the wheel when you can integrate existing, reliable solutions? One of the smartest ways to reduce FinTech app development costs is by using third-party services.

For example, instead of building financial data-sharing capabilities from scratch, you can integrate with platforms like Plaid. These external services provide pre-built solutions for features like payment processing, account verification, and data connectivity. Not only does this approach save on development time, but it also ensures a smoother, more reliable user experience.

At TECHVIFY, we’ve made it a habit to leverage third-party tools whenever possible, enabling our clients to save both time and money while still delivering top-notch functionality.
