B. Comparing Ways to Build a Marketplace Platform
Now, let’s see the different ways in which you can build an e-commerce marketplace website. Keep in mind that use cases are different and it is not possible to figure out the best way to build one for every business. We will look at each option to help you gain a better understanding. To get a precise recommendation, you need to get in touch with your e-commerce web development company.
1. Coding from scratch
If you want everything just the way you imagined and if you can hire professional developers, this option will be suitable for you. In this method, you will have complete access to the code, no third-party software, and complete ownership of licensing.
On the other hand, this approach is quite time-consuming because a platform that handles all the transactions in a secure and smooth way is difficult to build. Even for adding custom features, a lot of experiment has to be done, which will definitely put a drain on your pocket.
What is the cost of this approach?
Building your marketplace platform from scratch typically starts from $50,000 to $1,00,000, depending on features, security, scalability, and integrations.
2. Website Builder
Creating a marketplace website through a website builder is affordable. You can choose platforms like WordPress + WooCommerce, Magento (Adobe Commerce), or Shopify with marketplace extensions. For more information, go through our blog on Best E-commerce CMS for Online Businesses.
These solutions come with extensive customization options. Choosing this method is one of the cheapest ways if you can handle plugins and other tools.
What is the cost of this approach?
Building a marketplace website through website builders usually costs between $15,000 and $30,000
3. No-Code / Low-Code Marketplace Platforms
No-code and low-code marketplace platforms offer one of the fastest ways to launch a multi-vendor marketplace with minimal technical effort. These platforms provide pre-built workflows, vendor management features, and payment handling, allowing businesses to go live quickly without building everything from scratch. They are especially suitable for early-stage startups, MVPs, or businesses looking to validate an idea before investing heavily in custom development.
What is the cost of this approach?
Creating a marketplace website via a non-code method generally costs $5,000 to $15,000 per year
4. API-First Marketplace Development
API-first marketplace development is a modern approach where the core marketplace functionalities are built or integrated using APIs, while the frontend and user experience are developed independently. Instead of tightly coupling all features into a single system, this approach allows businesses to connect best-in-class services for payments, search, notifications, analytics, and vendor management through APIs.
Although this approach requires a skilled API development team and a higher initial investment than no-code solutions, it provides long-term control, customization, and performance benefits, making it ideal for businesses planning sustained growth and multi-channel expansion.
What is the cost of this approach?
Creating a marketplace website using an API-first approach typically costs between $20,000 and $40,000
