For startups, the cost will be minimal; however, for large enterprises, the price can vary as per the features, functionalities, customizations, integrations, etc.

Here are some influential factors that affect the cost of multi-vendor e-commerce marketplace development:

Unique Requirements

Your multi-vendor e-commerce marketplace development cost depends on what are your requirements with your marketplace website.

There are mainly two types of requirements in any e-commerce marketplace development project:

  • The regular (usual) features present in currently functioning websites in the market.
  • Unique features that are not present in any popular website in the current market.

If your requirement is general, you can fulfill it readily by leveraging some ready-made multi-vendor software. However, if your required features are unique and customized, you might need modules, extensions, plugins, or add-ons that can meet your multi-vendor e-commerce marketplace needs.

The Business Model

The choice of multi-vendor e-commerce marketplace depends massively on the type of business model you will follow. As a result, the choice affects the overall cost of your project. For instance, if you want to develop a simple B2C or B2B multi-vendor e-commerce marketplace to sell, you have all the options available at your disposal. You can choose free, premium, open-source, or SaaS options.

Investment in Upfront or Parts

Should you invest upfront or invest in parts? This is one of the crucial questions that can influence multi-vendor e-commerce development costs. If you go with open-source options, you will need to make some upfront investments to purchase the source code or purchase different modules to customize the marketplace. Although you can’t invest a heavy amount upfront, you can opt for a SaaS e-commerce platform.

Development Approach

Off-the-shelf software is the right choice for businesses that want to create and launch an online store as soon as possible. Moreover, when you are leveraging the already-built products, then the options like testing, wireframing, and development get skipped.

The per-hour hiring cost can range between $100 to $300, based on the location, skill-set, expertise, experience, and technology stacks. You can also fix one price for the entire project instead of the per-hour price.

UX/UI Design

When it comes to UX/UI design, the price can greatly vary. Your multi-vendor e-commerce marketplace design usually depends on your e-commerce site’s complexity, features, functionalities, integrations, design choice, size, budget, and more. It can take about $10,000 to $80,000 (or more), varying according to the number of pages and features.

Back-End and Front-End Development

The front-end and back-end developments are the soul and structure of the multi-vendor e-commerce marketplace. The more complex and time-taking your e-commerce marketplace will be, the more money it will require. However, back-end and front-end development costs can be anywhere around $50,000 to $200,000 or more, varying according to the requirements and complexities.
