How to Build an Online Marketplace Website [2024 Insights]

Online marketplace platforms are believed to be among the most promising e-commerce industries. However, two-thirds of them close in the first year. But why?

In this article, NEKLO experts share insights on how to avoid mistakes when creating a marketplace website and choosing the right platform, a step-by-step guide on building a successful marketplace store, and more. Buckle up!

Key Takeaways

  • The main benefits of building a marketplace are reaching wide audiences, profit generation according to the monetization model, and boosting online presence for brands.
  • The key features of an online marketplace include quicklogin and onboarding, easy search and navigation, analytics tools, convenient user accounts, and more.
  • Marketplace website development requires thorough planning and research. Building an MVP first can be an excellent way to prove your project's concept and receive feedback.

What Is a Marketplace?

A marketplace is an online platform where sellers and buyers find and interact with each other. Such platforms have very different specializations – from universal trading platforms with goods for all occasions to industry-specific marketplaces for services. For example, financial, insurance, or consulting. Depending on the website's specificity, companies and individuals can act as sellers.

How are marketplace platforms different from ordinary online stores?

There are several main differences between marketplaces and common online stores:

  • The number of sellers and goods on the website

An online store usually offers products of one or more brands. The marketplace presents products from various sellers, often from many different categories. In this sense, it is like a large online hypermarket.

  • Offline presence

Many online stores exist offline, too, in the form of brick-and-mortar stores. Marketplaces usually do not have offline stores, but there are pickup points.

  • Audience and geography

Marketplaces tend to focus a lot of attention and resources on user acquisition. Therefore, they have a larger audience and traffic than normal online stores. In addition, advanced logistics allow marketplaces to work with a wider geography.

Online Marketplaces by Type

There are several types of marketplaces. Let’s take a look at the table below to get a bird’s eye view on their types before creating a marketplace website.

Types of marketplaces: B2B, B2C, C2C, Hybrid, Vertical, horizontal, Services marketplaces, goods marketplaces.

If you want to build a marketplace website, you should know all the options: by specialization, by application, and by target audience.

B2B (business-to-business)

This type of business model allows companies to trade goods and services. For example, Alibaba marketplace facilitates selling products in bulk between businesses. Monetization schemes for such platforms usually involve transaction or membership fees.

B2C (business-to-consumer)

A  model where businesses sell products and goods to individual customers while the marketplace charges a small percentage for every sale as a commission. An example of such a marketplace is Walmart, allowing businesses to achieve wide recognition and offer an extensive product range.

C2C (consumer-to-consumer)


A type of marketplace where individuals buy and sell products or services. The monetization source for such platforms is either a transaction or a listing fee. A prominent example of a C2C marketplace is Craigslist, where you can find everything from furniture and appliances to clothes, housing, and jobs.

Hybrid

This type combines all the abovementioned marketplace approaches. How does it work? Let's look at Amazon. Although it is primarily a B2C marketplace, the platform has expanded over the years and now offers B2B opportunities (Amazon Business) and C2C options (Amazon for used items).

Online Marketplaces By Specialization

This categorization is based on the level of the platform's narrow focus on the specific areas. The options are:

Vertical marketplaces

Vertical marketplaces have narrow specialization, allowing them to sell only particular types of goods/services: real estate, vintage items, digital products, and musical instruments. For example, Chewy focuses exclusively on pet supplies, offering a wide selection of food, treats, toys, and accessories for all kinds of pets.

Horizontal marketplaces 

Horizontal marketplaces do not have specific niches and offer goods and services across multiple industries. Such platforms usually charge a transaction fee, and eBay is one of them. Started as an auction site, it has evolved into a massive marketplace with both new and used products.

Online Marketplaces By Application

Age-old question: mobile app or web app? The best practice from industry leaders is to have both.

Mobile marketplace 

Mobile marketplace apps allow on-the-go browsing and are very convenient and accessible. Additionally, smartphones enable marketplaces to offer location-specific deals or services. Nevertheless, when building a marketplace mobile app, remember that it will have a simpler interface and smaller screen size, which might not suit some customers.

Web marketplaces

Web marketplace is convenient to use from the desktop, but also must be responsive to provide the best user experience for mobile users. The advantages include a larger screen compared to mobile apps, allowing for more detailed view and research-intensive purchases, and smooth running of complex transactions.

Other Types

  • Decentralized: a newish trend in marketplace website development that diverges from the traditional way of running a business. Built on blockchain technology, decentralized marketplaces create a peer-to-peer connection, allowing users to interact directly without a central authority. They are good for selling digital goods, data sharing, and financial services. Monetization models for this type include protocol and service fees and token-based models. For example, OpenSea is the world's first and largest decentralized marketplace for non-fungible tokens.
  • Service-focused platforms connect service providers with clients and include freelance websites, food delivery, home services, and pet care. For example, Upwork is a vast freelance website that connects businesses and individuals with freelance professionals for all sorts of digital and creative work.
  • P2P rental: such marketplaces help connect people offering temporary rental services with those needing them. A well-known example of such a platform is Airbnb. It offers many affordable accommodations and provides the platform and tools for hosts to list their properties, set pricing and availability, and communicate with potential guests.

Key Features of an Online Marketplace Website

Let's skip the most obvious features, such as well-designed pages or strong security measures, and concentrate on the other amazing features that can make your marketplace stand out.

Simple log-in and sign-in process 

Ask only for necessary information and enable social sign-in to save time and keep vendors' and customers' attention focused.

Easy onboarding

Facilitate website familiarization for newbies by creating clear FAQs and how-to videos for sellers. Provide some tips in dashboard navigation to ensure no one is left puzzled.

Convenient personal accounts

Make the personal account page easy to navigate and change settings, as no one likes to spend hours unraveling complex solutions.

Easy search and navigation

Make sure people can find what they want in an ocean of diverse goods and services. Organize categorization properly to avoid confusion.

Mobile friendliness

If you are considering creating a marketplace website, think about the convenience of its use on mobile devices. A responsive interface is the key.

Payment gateways

Don't frustrate customers with scarce payment methods. Integrate your marketplace's most popular payment systems to create a seamless checkout experience.

Advanced analytics

Decide how you will track marketplace website metrics, marketing, and sales performance. Develop a dashboard with an intuitive interface and data visualization capabilities. 

Ratings and reviews

Other customers' experiences can provide valuable insights into a product, making it more likely to be bought or highlighting its sufficient cons. Enabling product reviews can help your customer make the most informed purchase decision.

Social media sharing options

Let people boast about their purchases on social media! Boost engagement by adding social sharing buttons to your marketplace pages.

Personalization

A tailored approach to your customers is the one thing you cannot ignore in the 21st century. Create personalized offers and recommendations and give your customers exactly what they need.

Technology Stack

While giants such as Amazon, Uber, or Etsy are setting trends in the marketplace domain, this does not mean there is no room for new projects. It is never too late to fill a niche or bring new ideas to life. What technologies and tools can help you with that task? We are going to explore marketplace website development tech stack.

What are the components of the tech stack? 

It includes programming languages, libraries, frameworks, and other tools to create software, such as a marketplace website.

What defines the tech stack in marketplace website development? 

The answer is pretty obvious: budget, time, and project size. The development stage can involve building a marketplace from scratch or customizing and modifying an existing solution.

There 3 main technologies that are particularly suitable for building a marketplace and are acknowledged worldwide:

  • MEAN stack strongly focuses on JavaScript and includes MongoDB, a flexible, non-relational database; Express.js, a lightweight web framework for Node.js that simplifies building web applications; Angular.js, a frontend framework; and Node.js, an efficient runtime environment. MEAN provides the product's scalability, enables fast development, and allows the implementation of real-time features. On the other hand, it has a steeper learning curve for beginner developers, and debugging may require more effort.
  • Ruby on Rails focuses on developer productivity and consists of Ruby, known for its great readability, the Ruby on Rails web framework, and PostgreSQL, a powerful and open-source relational database. The stack allows fast prototyping, is mature and stable, and has a large community. Despite all the advantages, Rails applications might require more optimization for high-traffic scenarios.
  • LAMP focuses on reliability and efficiency, which are gained through its well-integrated components. Linux is the operating system layer in the stack; Apache web server software handles client requests and delivers web pages to users. MySQL is a database management system, while PHP is the core development language (Perl or Python can replace it). The stack is cost-effective and versatile, with many professionals available. Still, the product built on this stack can be challenging to scale and configure.

How do you choose the right stack for creating a marketplace website? 

It considerably depends on the type of platform you want to develop: B2B, C2C, B2C, or hybrid. B2B marketplaces may prioritize seamless integrations to handle complex transactions. In contrast, B2C marketplaces might focus on a user-friendly and intuitive interface requiring a powerful frontend framework.

If you have any concerns about choosing the right stack, our team of professionals in e-commerce software development is ready to consult you and carefully review your project.

Benefits & Risks of Building Marketplace Websites

Marketplace website development advantages: wider customer base, revenue generation, competitive pricing. Risks: high initial investments, high competition, dependence on sellers.

Benefits

  •  A large selection of goods or services from different suppliers attracts more customers than individual online stores. It is more convenient for suppliers to offer goods and services in the marketplace, where there is already demand, than to create and promote their website or online store;
  • The marketplace relieves the owner of problems with the delivery, communication with the buyer, and settlement order issues. All this falls on the suppliers, and the owner of the marketplace is engaged in attracting users and developing the online platform.
  • Revenue generation allows you to earn commissions on sales, reach more buyers with low listing fees, get discovered by targeted ads, unlock premium sales tools with memberships, and enjoy secure and easy transactions with minimal fees — the options are ample!
  • Without functions like inventory management, order fulfillment, and customer service, which are completely sellers' responsibilities, you can focus on your platform development and growth.

Risks

Even though today, the desire to create a marketplace website may seem a good idea to get quick profit, it is also necessary to remember the risks this business idea may bring:

  • The development and launch of a marketplace require a significant amount of investment at the start. You'll have to attract and retain buyers and suppliers at the same time. That is, the marketing budget needs to be doubled;
  •  You will need an experienced e-commerce consulting team to provide careful analytics at the start, help with a quick launch of an online service, attract users at an early stage, and help mitigate challenging situations.

What Do You Need To Start an Online Marketplace?

While building a marketplace, it is great to dream big and see your platform next to Amazon. Still, at the beginning of such a massive project, it is wise to start from small steps and check whether the sellers and customers will find your marketplace lovely.

The development of the minimum viable product (MVP) will allow you to launch your website quickly. After the start, you can and should develop the functionality of the marketplace.

On average, developing an MVP for a marketplace will take 3-4 months. This time includes the entire process, from analytics and design to development itself, if each stage is promptly coordinated.

To start an online marketplace you need:

  1. A robust product search feature will help customers find the right goods.
  2. Seamless and reliable checkout for better conversions and user experience.
  3. Order processing and tracking mechanism for customers' and seller's convenience.
  4. Order and catalog management for sellers for quick and reliable order fulfillment.
  5. Analytics and reporting for sellers to make data-driven decisions.
  6. Communication tools between all parties involved in marketplace activities.

Remember to include a payment module that will ensure the possibility of safe purchases and the protection of payment data of both suppliers and customers.

Other important marketplace features include tools for sales and marketing, QA, and tax management. As you can see, developing a marketplace website with basic features requires a lot of effort and determination. Let's examine the detailed step-by-step process of building a marketplace to learn how to run your own marketplace.

Steps To Build an Online Marketplace Website

Marketplace website building process: define the niche, make a plan, select the development team, develop core features and integrations, launch your marketplace, focus on promotion and growth.

Marketplace development is a complex process that requires maximum concentration and efforts, as well as a qualified e-commerce development service provider. To avoid difficulties in developing and launching a marketplace, you need to plan it carefully and make data-driven decisions at each step.

So, how do you build an online marketplace website? Check out our step-by-step guide below.

Step 1. Decide on the niche

Determine the marketplace type and monetization model you'll use. Before starting development, carefully analyze the chosen niche: conduct market research, examine competitors' products, and determine the target audience.

Step 2. Make a detailed plan

Make a detailed plan which will indicate all business processes and stages of interaction with users within the service. Keep in mind that:

  • The internal interface and website structure should be intuitive to the user. There should not be complex algorithms that can repel a client who first visited the resource.
  • The catalog of goods should be created based on generally accepted and well-known categories. You don't need to develop your own; you can analyze competitor sites in detail and use the ratings of popular queries and categories. In future, listen to user requests, upgrade existing product categories, or create new ones.
  • You should have a detailed marketing strategy, which will include online and offline promotion of the project. From the very beginning, it is necessary to provide all channels and sources of communication for each target audience.

Step 3. Define the required functionality

While defining the required functionality, it is important to list the features and prioritize them, as you probably won't be able to implement them all at once while building a marketplace. You can start from must-haves, moving to should-haves and nice-to-have features, or choose according to their value to users. Use market research results to determine the functionality and ensure that valuable features will be implemented first.

Step 4. Select the development team

Assemble a development team. Think over its composition, hierarchy, and the interaction model between employees of various departments. Determine which specialists will work with you in a team and which ones you will outsource.

Remember the 2 main principles before selecting a team to provide you with e-commerce services:

  • Firstly, specialists must be high-level, have knowledge of launching new projects, and have experience delivering custom ecommerce solutions.
  • Secondly, the most expensive services do not always equal the highest quality. That is why you should pay special attention to the expertise of the e-commerce website design company you are going to hire.

If assembling the team yourself seems burdensome, you can always hire a software development services company to assemble the right dedicated team tailored to your project's specific needs.

Step 5. Choose a technology stack

The tech stack for marketplace development can be divided into two parts: client-side technologies, which include the website's visual elements, and server-side technologies, which encompass programming languages, frameworks, and databases. 

Client's interface: HTML, CSS, and JavaScript. 

Programming languages: C++, Java, Python, PHP, Ruby, etc.

Leading frameworks and libraries: Angular, React.js, Vue.js, Ruby on Rails, Fusion.Js, Backbone.js, Django.

Databases/database management system: MongoDB, MySQL, Oracle.

Cloud solutions: Amazon Web Services, Azure, Google Cloud.

Depending on the marketplace's size, the tech stack can vary. The well-known modern marketplaces work on completely different technologies yet bloom. That is why it is more about the correct use of technologies rather than trying to find one universal solution.

Step 6. Design the architecture

There are different types of software architecture that your future marketplace will be based on. The choice depends on your needs for scalability and flexibility, and user experience requirements. Here are some examples to consider:

Monolithic Architecture is a simpler structure where all functionalities are bundled together in a single codebase. It's sufficient for small marketplaces but can become cumbersome and difficult to maintain as the platform grows.

Microservices Architecture breaks down the marketplace into smaller, independent services that communicate with each other. It offers greater scalability and flexibility but requires more development effort.

Headless Architecture separates the front end (user interface) from the back end (data and logic). The backend provides APIs that can be accessed by any front end, making it a good choice for multi-platform marketplaces (web, mobile app, etc.).

Step 7. Develop core features and integrations

Creating a marketplace website starts with the main features and integrations. The solution must contain all features required for seamless operation. Leave all the should-haves and nice-to-haves to the further development cycles. 

What to start from? Marketplaces usually include user accounts and profiles, product listings and search, shopping cart and checkout, and product listing and order management. Provide a comprehensive admin interface for managing the marketplace, including adding sellers, monitoring transactions, analyzing platform usage, and setting fees.

Step 8. Choose hosting and deploy

Selecting a hosting provider is vital as the server characteristics influence your store’s load speed and overall performance. While choosing a hosting provider for your marketplace website, consider:

  • Pricing: choose the solution according to your budget
  • Performance: bad performance can lead to lost sales
  • Easy scaling: the ability of the server to deal with the increased traffic effectively
  • Content delivery network for better speed and performance
  • Security: SSL certificates, spam filters, firewall, DDoS protection
  • Automated backups: provide better customer’s data safety
  • Support: exceptional support from hosting providers facilitates troubleshooting

After selecting a suitable provider, ensure that your marketplace runs smoothly and provides a great user experience.

Step 9. Continue building a marketplace

When all the feedback from the previous step is collected and analyzed, and you are sure that the target audience warmly accepts your product, you can continue marketplace website development. At this step, you should focus on the feedback received and users' pain points and figure out how to resolve them. The development team will add more features to the product and even make some design changes or modify user flow.

Step 10. Focus on promotion and growth

As you planned the platform's promotion in advance at Step 2, it is now high time to launch the campaign! Social media marketing, ads, collaboration with influencers, content marketing, SEO, and partnerships — the array is impressively wide.

Both sellers and buyers will evaluate your commission rates and the design and platform's ease of use. 

How to attract sellers and customers: create clear refund policy, introduce review and rating feature, use quality media.

When a marketplace website creation is completed and everything launched, consider planning your platform growth and further development. It may include scaling, introducing new features and payment gateways, expanding to new markets, or building community features.

 If you follow the steps and recommendations outlined, you will have a better chance of finding your place in the market. Be bold and make mistakes; constantly improve your app, stay on top of current trends, and listen to your users.

Remember that with the right calculations, thought-out marketing, and PR activities, the payback of marketplace website development will be 1 to 3 years. Then, the website will work for a profit.

Neklo Expert's Tips on Creating a Marketplace Website

Our e-commerce development experts highlighted some tips to help you create a successful marketplace. Here they are:

  • Security must be the first thing to consider when building a marketplace. Think about your platform’s security measures and regulatory compliance at the planning step: introduce a role-based permission model, choose suitable fraud detection tools, and enable multi-factor authentication and a strict verification process for sellers to avoid counterfeit goods. Conduct regular data security checks, and do not forget about data backups.
  • Marketplace SEO optimization starts with listing optimization and is the sellers’ sole responsibility. Nevertheless, as the platform owner, you should provide the environment for that optimization through well-designed product description templates and breadcrumbs. Ensure your marketplace is mobile-friendly and encourage your sellers to create quality content.
  • Consider using automation on your marketplace for image improvement, customer service (chatbots), financial processes (invoicing), marketing processes (distribution of marketing content), analytics (auto generated reports), personalization (product upselling and targeted product offerings), etc. Automation increases efficiency and creates a better user experience for sellers and customers.
