The pandemic has reinforced the transition towards a more digital world and spawned changes in online shopping behaviors likely to have lasting effects. In addition, it has also backed online shopping, enabling e-commerce businesses to sell goods and services anywhere and allowing consumers to find different products in one place.

According to research, online consumer spending is expected to reach $36 billion in 2023, while the global e-commerce growth rate is forecasted at 10.4%. The e-commerce revenue is expected to surge to $6.5 trillion. These astonishing figures seem promising for entrepreneurs who want to invest in online marketplace development and develop their e-commerce platforms like Amazon, eBay, or Alibaba. This article sheds light on the essentials of building an online marketplace. Read on to know more. 

What is an Online Marketplace Platform?

An online marketplace or e-marketplace is an e-commerce platform that allows customers and sellers to exchange goods and services over the Internet. The platform typically serves as an intermediary, facilitating transactions between buyers and sellers and generating revenues.

Some of the most common types of online marketplaces include:

1. Consumer-to-Consumer (C2C) Marketplaces: These platforms connect individuals who want to sell their used or unwanted items with those who want to buy them.

2. Business-to-Consumer (B2C) Marketplace: These platforms connect businesses that sell products or services directly to consumers.

3. Business-to-Business (B2B) Marketplaces: These platforms connect businesses that buy and sell goods and services to each other.

4. Niche Marketplaces: These platforms cater to specific industries or interests, such as handmade goods, vintage items, or pet supplies.

How to Build a Marketplace Platform?

Building an online marketplace is a multi-stage process that comprises different stages. It requires a deep understanding of user needs, effective collaboration between designers and developers, and a focus on quality assurance to ensure a successful marketplace launch.

1. Research your Marketplace Idea

Before building a marketplace, conduct market research to identify which products and services you should display on your website. You can create either a horizontal or a vertical marketplace. A horizontal market sells various goods (like Amazon), while a vertical marketplace caters to specific customers (like Airbnb). A horizontal marketplace allows you to serve customers and sell products from numerous market segments. Conversely, a vertical marketplace lets you focus on a niche segment and offer a personalized service. 

2. Know your Target Audience

Before you embark on online marketplace development, you will define your target audience, acquire information about them, and precisely what they want. It can allow you to showcase apt products and services and devise ingenious sales and marketing strategies to meet their expectations, effectively promoting your goods and services and boosting your sales. 

3. Essential Functional Features

An online marketplace should display some basic functional features that are convenient and improve user experience.

  • Sign In: A sign-in feature allows users to register and create an account. Users can register by using their email ID or social media accounts.
  • Product page: It gives detailed product information and displays information, photos, and videos.
  • Shopping cart: This feature is essential as it allows customers to store the products they want to buy in one place.
  • Wishlist: Customers can create and store lists of items they want to buy later.
  • Security: You must ensure the security of your marketplace with necessary SSL certificates, firewalls, and two-factor authentication. 
  • Payment options: Provide various payment options to your customers by installing payment gateways such as credit/debit cards, PayPal, Square, Stripe, and Apple Pay.
  • Search: This feature allows users to search for the items of their choice by typing into the search bar, ensuring the search is visible and easy to use. 
  • Admin panel: An admin dashboard allows the marketplace owner to manage and oversee transactions, payments, and shipping. 
  • Shipping: This feature allows customers to choose the preferred shipping method for their products.

4. Technology Stack

You will also require an appropriate technology stack for building an online marketplace. Ideally, it will combine programming languages, frameworks, libraries, and tools to build and run a particular software application or system.

  • Front-end – JavaScript, TypeScript, React, Redux, Next.js, HTML5, CSS3, and Gatsby.
  • Back-end – Ruby on Rails, Django, Node.js, and Express.js. 
  • DevOps – Linux, Ansible, Docker, and Terraform. 
  • Infrastructure – Digital Ocean and AWS.
  • Database – PostgreSQL, MySQL, MongoDB, Redis, and Firebase. 
  • Integrations – Google Analytics, PayPal, Stripe, HubSpot, MailChimp, and Skylight.

5. Choose a Business Model

The business model of an e-marketplace will depend on various factors, including the platform’s target market, the type of goods or services being offered, and the platform’s overall strategy. However, building an online marketplace can generate significant revenue and become profitable by leveraging one or more revenue streams.

  • Commission-Based Revenue: One of the most common revenue models for online marketplaces is to take a commission on every transaction on the platform. For example, the platform might take a percentage of the sale price when a product is sold or a fee for listing an item for sale.
  • Advertising: Another common revenue source for online marketplaces is advertising. Platforms might sell advertising space to businesses looking to promote their products to users on the platform.
  • Premium Services: Some online marketplaces offer premium services to users, such as enhanced listing options, increased visibility, and other benefits. These services can be provided on a subscription basis or for a fee.
  • Data Monetization: Online marketplaces can also monetize the data they collect on their users. For example, they might sell aggregated data on user behavior or purchase history to businesses interested in this information.
  • Physical Goods and Services: Some online marketplaces sell physical goods and services directly to consumers. It might include electronics, clothing, or home cleaning or delivery services.

6. Create a Business Plan 

Before building an online marketplace, entrepreneurs and business owners must create a comprehensive business plan to help them boost their online marketplace development strategies.

A comprehensive business plan should cover the following topics:

  • Executive Summary: It briefly overviews the online marketplace, its purpose, target market, and business objectives.
  • Market Analysis: The market analysis includes an in-depth analysis of the market demand for the product or service, the target audience, and competitors.
