1. What is a marketplace?
1.1. Marketplace : definition
A marketplace is an online platform that connects sellers and buyers in order to facilitate commercial transactions. Unlike a traditional e-commerce store, where a single actor offers their products, a marketplace allows multiple sellers to offer their products on the same site. This intermediation model offers numerous advantages:
- For buyers, there is a diversity of products and prices.
- For sellers, it is an opportunity to reach a wide audience without having to invest in the logistics and marketing of their own site.
In addition to connecting parties, the platform often provides complementary services such as payment management, logistics, and customer support, thereby ensuring a secure and optimized framework for all transactions. Concrete examples such as Amazon, Etsy, or Vinted perfectly illustrate this concept, offering intuitive interfaces and handling the technical and legal aspects.
It is crucial to understand that a marketplace is based on the idea of pooling resources and benefiting from significant network effects, where the platform’s value increases with the number of registered users. This definition will help you grasp the challenges and opportunities related to building your own marketplace.
2.2. What are the different types of marketplaces?
Marketplaces come in several typologies depending on the actors involved and the nature of the products or services offered. They are generally divided into six main categories:
- B2B (Business-to-Business): These platforms connect businesses. They are used for the sale of industrial products, the provision of specialized services, or to facilitate strategic partnerships between companies.
- B2C (Business-to-Consumer): Here, companies sell directly to end consumers. Iconic examples include Amazon or Ebay, where user experience and inventory management are key elements to meet mass market demand.
- C2C (Consumer-to-Consumer): These marketplaces facilitate transactions between individuals. They often rely on rating and feedback systems to build trust, as seen with Vinted.
B2B2C (Business-to-Business-to-Consumer): This model is based on a partnership between two companies the supplier and an intermediary (marketplace, retailer) who handles marketing the products to consumers. In this way, the supplier benefits from the intermediary’s visibility and logistics while maintaining its brand image.
C2B2C (Consumer-to-Business-to-Consumer): Here, consumers contribute to the offer (ideas, content, or products) that a company then leverages and offers to other consumers, as demonstrated by BackMarket. This model fosters collaborative innovation and a fine-tuned adaptation of the offer to market expectations.
Service Marketplace: This model connects service providers (freelancers, consultants, artisans) with end clients, relying on rating systems to build trust and ensure the quality of the services provided.
Some platforms adopt a hybrid model, where the operator offers its own products in addition to those provided by other sellers. These distinctions are essential for choosing the positioning strategy and defining the functionalities of your marketplace. Indeed, the design of the interface, logistics, and payment management will vary depending on the type of marketplace chosen. Therefore, it is crucial to identify the typology that best aligns with your objectives and market demand.
Before you get started, analyze the demand and the competition. A well-targeted marketplace model (B2B, B2C, C2C, services...) will enable you to maximize engagement and profitability. If you opt for a niche, make sure it has growth potential, and that there are enough buyers and sellers to drive your platform.

2. Difference between build a marketplace and build a boutique-style e-commerce site
- In a classic online store, a single merchant is responsible for the entire sales chain: stock management, pricing, shipping, and after-sales service. This offers complete control over quality and the user experience, but also limits the offer to what the company itself provides.
- Conversely, a marketplace acts as an intermediary by bringing together several independent sellers on a single platform. The operator’s role is to provide a robust technical infrastructure, secure payments, and ensure the legal compliance of all transactions. This model allows for a much greater variety of products and services than a single store, thereby attracting a larger number of buyers. However, this multiplicity of parties also poses challenges in terms of dispute management, consistency of the user experience, and verification of the quality of the offers.

3. How to build a marketplace?
3.1. Conduct market research
Before building a marketplace, the first step is to conduct an in-depth market study. It is imperative to understand the sector in which you wish to operate, to identify unmet needs, and to analyze the competition. This involves collecting data on purchasing behaviors, consumption trends, and the positioning of the existing players. A thorough market analysis will allow you to validate the viability of your project and to adjust your strategy accordingly. You must also identify your target audience and create detailed personas that represent your future users, both for buyers and sellers. This approach will help you pinpoint the essential features to integrate into your platform. Finally, do not forget to budget for this analysis phase, as it forms the basis of your business plan and financial projections.
3.2. Define your concept
After studying the market, you must precisely define the concept of your marketplace. It is essential to differentiate yourself: choose whether you want to position yourself in a general market or, on the contrary, exploit a specific niche. A niche positioning allows you to focus your marketing efforts and offer a unique value proposition to a specific segment of users.
The definition of your concept must include a description of the products or services offered, the added value compared to the competition, and how you plan to create synergies between sellers and buyers. Also, consider the technological and ergonomic aspects that will make your platform attractive and intuitive. A clear vision of your concept will serve as a roadmap for all the subsequent steps of the project.
3.3. Determine your persona
Creating personas is an essential step to understand and segment your audience. It involves outlining typical profiles of your future users by identifying their needs, behaviors, and obstacles. On the buyers’ side, you must define their expectations regarding navigation, security, and product quality.
For sellers, it is necessary to understand their motivations, their expectations in terms of management tools, and the criteria that would encourage them to join your platform. These personas will allow you to customize the user interface, define tailored customer journeys, and guide your marketing strategy. By relying on both quantitative and qualitative data gathered from surveys and interviews, you will be able to refine your offering so that it meets the identified needs precisely.

3.4. Choose a business model
The business model defines how your marketplace will generate revenue. The classic options include sales commission, registration fees, subscriptions, or even one-time listing fees. Each model has its own advantages and disadvantages:
- Sales commission: Allows you to charge only when the transaction is successful, but requires carefully calibrated pricing to remain competitive.
- Subscriptions: Generate recurring revenue, but may discourage sellers if the cost is considered too high.
- Registration or one-time fees: Easy to understand, but risk deterring sellers due to a high initial cost.
The key is to adapt your model to your target market and the added value you offer. You can also consider a hybrid model that combines several of these options, in order to diversify your revenue streams and optimize the profitability of your platform.
3.5. SaaS, On-Premise, or Open Source
Building a marketplace involves choosing between three types of solutions: SaaS, On-Premise, and Open Source. Each presents advantages and disadvantages depending on your needs and resources. :
- SaaS (Software as a Service): A SaaS solution allows you to launch a marketplace quickly thanks to a turnkey platform accessible via the cloud. It offers a low initial cost with a subscription that includes maintenance, hosting, and updates, while ensuring security and scalability. However, the main disadvantage is that you do not actually own the solution.
- On-Premise: With an On-Premise solution, the software is installed directly on your servers, offering complete customization and total control without recurring fees. This model is suited for companies that wish to manage their infrastructure and avoid any dependency on an external provider. However, the initial investment can be high, and maintenance as well as updates require in-house technical skills, which can complicate the long-term management of the platform.
- Open Source: Open Source CMS solutions, such as WordPress or Prestashop with multi-vendor plugins, allow you to build a marketplace at a lower cost with no subscription or commission fees. They are a good option for testing a project before investing further. However, these solutions present limitations in terms of user experience, performance, and scalability, making their evolution difficult without a major overhaul in the event of significant updates to the CMS used.
The choice of model depends on your needs and resources. SaaS is ideal for a rapid launch, On-Premise for complete control, and Open Source CMS for testing a project at a lower cost. A detailed specification document is recommended to choose the best solution. You can learn more about this topic by reading our dedicated article on the subject.
3.6. Determine the payment system
The payment system is one of the crucial elements of a marketplace. In a multi-vendor model, managing transactions becomes more complex than in traditional e-commerce. You need to implement a payment system capable of managing the financial flows between buyers, sellers, and the platform operator. Several solutions exist, such as PayPal, Stripe, or specialized providers like MangoPay and Lemon Way. The important thing is to choose a solution that offers security guarantees, compatibility with multiple currencies, and the ability to handle subscriptions or recurring payments. Don’t forget to evaluate the transaction fees and the quality of the technical support provided by the provider, as these elements will directly impact your profitability and the trust of your users.
3.7. What is the legal framework for marketplaces?
The creation of a marketplace entails numerous legal and regulatory obligations. It is imperative to draft clear and comprehensive General Terms and Conditions of Sale (GTC) that specify the responsibilities of sellers, buyers, and the platform. These GTC should notably cover:- Payment and commission terms,
- Dispute resolution and returns management,
- The protection of personal data, in accordance with the GDPR
3.8. Define your budget
Establishing a projected budget is a fundamental step. You must take into account all costs related to:
- The design and development of the platform,
- Hosting and maintenance (especially if you opt for an On-Premise or Open Source solution),
- Marketing campaigns and communication,
- Legal and administrative fees for starting the business.
- The budget can vary considerably depending on the complexity of the project and the chosen technical solutions.
For example, custom development can cost from €35,000 to over €150,000 for a high-performing MVP. A precise estimate will allow you to raise the necessary funds and ensure sound financial management from the start.
3.9. Find sellers
Without quality sellers, even the best marketplace cannot thrive. From the very beginning, you need to implement a seller recruitment strategy. This involves drafting a convincing sales presentation that details the benefits of joining your platform (reduced commission, increased visibility, marketing support, etc.). It is important to target sellers that align with your niche or positioning, whether by conducting online research or by attending trade shows to find prospects. Also, be sure to verify their online reputation and reliability, because the quality of the sellers determines the credibility and success of your marketplace.

4. Prepare your launch
The launch of your marketplace must be carefully planned to maximize its impact. A pre-launch campaign helps generate excitement and gather initial feedback. It involves setting a launch schedule, crafting a strong marketing message, and choosing the appropriate communication channels (social media, email marketing, partnerships, targeted ads, etc.).
A successful launch strategy also includes offering promotional deals for early users, platform demonstrations, and online events. This moment is crucial to build your brand image and establish a trusting relationship with your future users. Regular monitoring and performance analysis from the outset will allow you to quickly adjust your strategy to ensure sustained growth and a gradual scaling of your marketplace.
5. Marketing strategy and post-launch follow-up
Once your marketplace is launched, the work doesn’t stop. The success of your platform strongly depends on a solid marketing strategy and regular performance monitoring.
First, it is essential to invest in search engine optimization (SEO) to ensure organic visibility. Advertising campaigns on Google Ads and on social media platforms such as Facebook, Instagram, TikTok, or LinkedIn should be deployed to reach your target audience. At the same time, it is recommended to implement content strategies (blog articles, explanatory videos, infographics) in order to attract and educate users about the advantages of your marketplace.
Next, post-launch monitoring is crucial. Use analytics tools to measure key indicators such as conversion rate, number of sign-ups, transaction frequency, and customer satisfaction. This data will allow you to
identify areas for improvement and optimize the user experience.
Furthermore, customer retention is a strategic aspect. Implementing a review and rating system, as well as loyalty programs, helps to establish a lasting relationship with your users. Finally, do not hesitate to enlist the help of a specialized provider to support the growth of your marketplace, such as Origami Marketplace, which offers a proven SaaS solution to accelerate the launch and scaling of your project.
Invest in SEO for natural referencing, use paid advertising for a quick start (Google Ads, Facebook, TikTok) and implement an engaging content strategy (articles, videos, testimonials). Build loyalty among your first users with reward programs and exclusive offers. Thorough performance analysis (traffic, conversion rates, customer satisfaction) will also be essential to adjust your strategy and optimize your results.
