With ecommerce sales reaching $6.3 trillion in 2023 and expected to hit $8.1 trillion by 2026, figuring out how to build a marketplace app sounds like a lucrative idea. However, with giants like Amazon, AliExpress, and eBay roaming the market, businesses may feel like entering the space is too challenging.

Luckily, multiple niches still require filling in, and new opportunities arise every day. If you are ready to begin your own project, this article will help you understand how to create a marketplace app that succeeds. We will also explore the most prominent niches, top applications on the market, suitable tech stacks, and app development costs for the business-to-consumer and business-to-business ecommerce marketplace spaces.

Fastest-growing marketplace niches in 2024

With giants like Amazon and eBay snatching up significant market share, it may seem like penetrating the market is impossible. However, there are a few emerging niches for ecommerce marketplace development.

  • Digital artwork & NFT

The NFT market is growing fast, and its market value is expected to hit $342.54 billion by the end of 2032. The digital art industry is gaining more and more traction and recognition, so creating an NFT marketplace where users can sell and buy art might be a great idea.

  • Home office equipment

Many people were forced to work from home during the peak of the pandemic, and even now, more than half of them share that they would be willing to take a pay cut to keep working remotely. The home office equipment market is here to stay for years and years, and launching a specialized marketplace platform would be beneficial.

  • Home gym & fitness equipment

The pandemic has also changed the way people work out and exercise. With many people working from home, they purchase home fitness equipment to stay in shape during the lockdown. The home fitness market was predicted to reach $16.55 billion in 2023 and is projected to experience a 10.1% growth by 2027. If you are interested in this niche, this is the year to jump on this train.

  • Eco-friendly products

With the growing concerns regarding climate change, more people strive to consume more environmentally conscious and make eco-friendly purchases. The diversity of products is quite broad, including metal bottles, reusable straws, sustainable clothes, biodegradable garbage bags, etc.

  • Online education

The way people get educated and deepen their expertise has drastically shifted in recent years. Online education allows people to access knowledge easier, faster, and more affordably. You can launch a marketplace where users can share their ebooks, courses, tutorials, lessons, and other educational materials.

  • Professional services

Instead of going through agencies and paying high fees, users nowadays prefer finding professional help online. You can create a marketplace app where people can offer their services and find gigs directly.

Crucial stages to create a marketplace app MVP that takes off

MVP stands for minimum viable product and serves as a budget-friendly idea validation process. Technically, it is a basic version of an app that holds the essential functions of the future solution and allows developers to get a feel of the app and collect some first feedback. In this part, we will focus on the benefits of MVPs and prototyping and talk about the creation process.

Benefits of prototypes in developing a marketplace app

  • Discover potential improvements

Mobile ecommerce app prototyping helps developers conceptualize the idea early in the development process and make adjustments. This stage allows the development team to gather feedback regarding the design and navigation and make improvements until the product is marketable.

  • Higher predictability

Creating a vision for the app based on the prototype enables the team to plan out the entire development cycle. The prototype, combined with detailed specifications, allows engineers to estimate the project's duration, break the process down, and evaluate the budget.

  • UX validation

According to Statista, the retention rate drops from 33.7% on the day of installation to 8.7% in just one month. This is a worrying statistic for marketplace app owners, and one of the best practices for mitigating such a drop is focusing on user experience. Create a prototype and run a user test to validate the UX design and continue to work on it in the future.

  • Smooth development process

Having an approved prototype is like working with a blueprint that saves time and eliminates misunderstandings. The prototypes can be used as a reference for developers, leaving no room for misinterpretation or errors.

The benefits of building an MVP

  • Securing funding: An MVP is a fully functioning product that can be used and interacted with. Although its functionality is limited, the app will be able to solve the main user problem and do the job. If you are interested in securing funding for your solution, it is recommended to build an MVP to demonstrate to potential investors and pique their interest.
  • Flexibility: Launching a feature-heavy product right away can be challenging, as it would complicate changes and adjustments. When compared to traditional websites — including an auction website or an ecommerce website — the app market is relatively volatile, and emerging technology forces it to constantly change. Further, your company can opt for ecommerce automation to drive the change faster and optimize processes. Starting gradually and taking small iterative steps allows companies to enable changes on the go without wasting too much time and resources.
  • Verifying market demand: There is also quite a lot of uncertainty in the world that can kill your idea in one day. For example, the COVID-19 pandemic took a toll on the hospitality industry, and releasing a tourism-related app in 2020 was not a great choice. Much like nowadays, the supply chain crisis hinders multiple sectors at once. Consider the current situation in the world before launching an app, and test your idea with an MVP to avoid monetary losses.

Marketplace app version 2.0

After developing an MVP and conducting user testing, collect all the valuable input and make changes to the current app. In the later stages, you can focus on fine-tuning the product, adding something unique that helps you stand out, and expanding the functionality. You can utilize various technologies to make your application more useful and interactive, as well as integrate business-oriented capabilities, such as by incorporating big data in ecommerce tools.

Key features of a marketplace app MVP

An MVP consists of basic features that are sufficient to solve a particular problem your target audience faces. Here is a list of essential elements your MVP should have.

Registration & signup

Registration allows users to sign up for the app and create their user profiles. Make sure to implement quick registration with existing Google, Facebook, and other social media accounts to streamline signup after downloading the application from an app store.

User profile

Users should be able to create and edit their profile pages, including contact information, payment preferences, and in-app pictures, as well as manage security options, such as turning on two-factor authentication.

Product search

Allow your users to browse the marketplace and search for items using keywords, with results preferably provided in real-time without loading delays. Add filtering options to fine-tune the search entry and find exactly what users need, including limiting results based on product pricing, size, color, material, or other relevant factors. Implement additional functions such as voice search or ML- or AI-assisted search.

Product page

Sellers or service providers need to be able to list their goods and services in as much detail as possible. Include keywords, tags, descriptions, images, 3D walkthroughs, and more to improve their experience and offer a straightforward template to accelerate product page creation.

Shopping cart

The shopping cart is one of the essential features when you’re figuring out how to build a marketplace app. It contains all the chosen items and their prices, as well as the total cost of the purchase. Make sure users can edit their shopping list and remove or add items quickly to checkout seamlessly.

Payment gateway

Payment gateways that create a secure payment system and support several payment methods to offer your users some variety are ideal. Consider having options for credit and debit cards, PayPal, Stripe, cash, cryptocurrency, etc., as part of your marketplace business model.


Whenever someone is interested in the user’s services or products, send them push notifications. You can also alert users about promotions, discounts, incoming messages, new arrivals, and other events to enhance engagement.

Admin panel

The admin panel allows the app owner to collect data, conduct analyses, remove or ban users, and manage payments, discounts, products, and other behind-the-scenes activities.

Outstanding features of a robust marketplace app version 2.0

After your MVP has gone through testing and feedback collection, you can move on to the next part and add new features or more advanced capabilities to your B2C or B2B marketplace app.

Social media integration

Social media platforms like Instagram are perfect for ecommerce integration through the use of an API. Instead of posting photos and encouraging users to visit your app, you can integrate your shop into Instagram and allow users to shop directly from there.

Advanced search

You can expand your search options by implementing tools commonly found in web apps, like image search, autocomplete, or machine learning algorithms. These sophisticated features will increase engagement and result in higher sales revenue.

Voice recognition

Voice recognition has become more prominent recently and allows people with visual impairments or certain mobility challenges to use the app without issues. Add this feature to the search engine as well as to the product page and shopping cart in your custom app for a smooth experience.

Messaging & chats

A messaging option can help customers get in touch with service providers and sellers for details. This leads to better experience and satisfaction as it allows for direct communication, making it a wise addition to your product development plan.

Augmented reality

Companies like Sephora have already implemented AR app features into their website to allow customers to try out their products right at home. They can apply beauty products to see if it’s the right color or texture through a web camera. This feature also works for apartment rentals, clothes, shoes, and other types of marketplaces.

Challenges in building a marketplace app

Building a marketplace app is an ambitious undertaking that requires tech skills and planning. In this part, we will focus on challenges you might face and how to mitigate them.

Choose a development stack

When choosing the appropriate technology stack for frontend and backend development of your vertical or horizontal marketplace app, focus on security, flexibility, and scalability. Don’t go with the most recent and emerging solutions, as they might not be as reliable yet and lack the seasoned engineers you will need to develop a marketplace app. Here are some of the most popular tech stacks that will help you deliver the best app you can:

  • LAMP (Linux, Apache, MySQL, PHP or Python)

LAMP is one of the oldest tech stacks and definitely stands the test of time. Linux is an operating system known to be reliable and secure. Apache is a web server used by giants like PayPal and Apple, whereas MySQL is a highly reliable database. Finally, PHP and Python are languages that are easy to learn, adapt, and integrate into servers and databases.

  • MEAN (MongoDB, Express.js, Angular.js, Node.js)

This tech stack is relatively easy to use and learn. It offers flexibility and allows developers to be innovative in their coding. MongoDB is a database that is easy to work with, while Angular is a simple tool for making single-page apps. Node.js will provide you with better performance than most frameworks, and Express will allow you to be innovative.

Be the soonest with MVP

According to Business of Apps, the number one reason for app failure — with 42% — is a lack of market research. Even though the business model seemed solid, these companies failed to identify market needs correctly and launched product or service marketplace apps that nobody wanted. To avoid this fate, work with a marketplace app development company and start with an MVP to test the idea and make sure users react positively to your solution and find it helpful.

Get ready to hire fast once you are growing

If you’re just learning how to build a marketplace app and have never hired software developers, you might feel overwhelmed and confused about where to start when building a team.

You can begin by collaborating with three or four development companies and assigning them a small task to assess their work. After choosing the right partner, they can augment their staff for your purposes and continue working on your project. Finally, selecting a proven tech stack is advised to make sure the corresponding pool of talents is available and accessible.

How does a marketplace app make money?

Now that you’ve established the functionality and got some regular users, you might wonder how to create a marketplace app that generates income. In this part, we will go over the most popular monetization models for a marketplace platform.

  • Commission on transactions

The commission is the most popular monetization method in ecommerce and marketplaces in general. For each transaction, the app gets a commission that varies depending on the products, delivery times, location, industry, etc.

Example: Amazon

  • Subscription

You can offer your app on a subscription basis, whether weekly, monthly, or yearly. We recommend including a free trial period to allow the customer to see what they can gain from the app before spending any money.

Example: Patreon

  • Listing fee

Another valid option for marketplace app monetization is taking a moderate listing fee for each posting.

Example: Upwork

  • Advertising models

You can sell your website and app space to companies willing to work with you and promote their products on your platform.

Example: Zillow

  • Pay per lead

This model is suitable for niche services and products that have lower engagement. The seller will only pay whenever a user interacts with the listing.

Example: LinkedIn jobs

  • Freemium

A freemium model offers free access to the app's basic features while requiring a fee for more advanced functions.

Example: Craigslist

Growth-hacking tech stack for creating a marketplace application

Online marketplace app development is a complicated process that requires technical know-how and experience. Here, we will explore some tools and hacks to help you smoothen your journey.

Quick prototyping

We have already talked about the benefits of prototyping and how it could enhance collaboration and save costs. Do not skip this step if you want to build a mobile marketplace app that finds its users.


Cross-platform development allows you to develop an app across multiple platforms using one code base. The three industry leaders are React Native, Flutter, and Xamarin. React Native is a framework that offers native platform capabilities and delivers top-notch UI elements that improve performance. Flutter is a newer solution with a hot reload and useful widgets that enrich the design. Finally, Xamarin provides a near-native experience and simplifies the process and cuts the time it takes to develop applications.

Programming languages

If you decide to create native solutions, you can choose between Kotlin and Java to build a complete marketplace app for Android. With apps like Uber, Spotify, and Instagram, Java is a world-renowned language still in use due to its security, simplicity, and debugging tools. Kotlin is a newer technology that has already gained appreciation from the community thanks to its lightweightness, Java interoperability, and short learning curve.

For iOS app development for marketplace solutions, you have a choice between Objective-C and Swift. Objective-C is an older technology that offers a wide pool of talents, lots of helpful documentation, and a high level of stability. On the other hand, Swift is a newer language that is much faster and safer and delivers better performance compared to its competitors.


When it comes to servers, we recommend sticking to Apache, NGINX, and Amazon EC2. Apache is the most popular web server: reliable, stable, and flexible. The server is continuously updated with new security patches and suits for beginners.

NGINX is another prominent server that offers simplicity, high speed, minimum memory usage, and a large community. Finally, Amazon EC2 provides reliability, a high level of security, flexibility, and excellent scalability.


DevOps is a part of agile methodology that has become widespread in the development community. This best practice will deliver faster deployment and improve the quality of the application. You can also achieve better transparency across the processes and higher productivity within the teams. Finally, DevOps practices will automate mundane tasks and help your developers focus on more creative activities.


The choice of databases is quite vast, so we will focus on just three. MySQL is a popular database that provides high performance, security, and scalability. DynamoDB is beloved for its cost-effectiveness, scalability, and serverless nature. Finally, PostgreSQL has a large community, reduced production costs, and fantastic security.
