Creating a multivendor marketplace is both a strategic move and an ambitious project. Though the business model eliminates the need for inventory management, it requires strict technical, logistical, and regulatory planning—particularly when it comes to multiparty payments. In this article, we offer a step-by-step guide for creating multivendor marketplaces, from initial design to launch.

Key takeaways

• A multivendor marketplace allows multiple independent sellers to offer their products and services to buyers. Marketplaces are subject to a complex legal framework stemming from several European directives and French laws, including EU Regulation 2019/1150 on platform-to-business (P2B) relations, the Digital Services Act (DSA), the General Data Protection Regulation (GDPR), the revised Payment Services Directive (PSD2), and the seventh revision of the EU Directive on Administrative Cooperation (DAC7).
  
• A marketplace can facilitate business-to-business (B2B), business-to-consumer (B2C), or consumer-to-consumer (C2C) transactions; it can be general-purpose or specialized, and it can even offer its own products and services. It has several options for generating revenue: sales commissions, subscriptions, fees for ancillary services, and fees for listings.
  
• From a technical standpoint, platform operators must choose between a software-as-a-service (SaaS) solution, open-source software, or a custom software solution. Financial flows are often managed by a payment service provider (PSP), but marketplaces can also become certified or obtain an exemption through the French Prudential Supervision and Resolution Authority (ACPR) in order to process transactions on behalf of third parties.
  
• Creating a multivendor marketplace requires meticulous planning. You must decide on a concept, positioning, and business model; choose a technical solution and legal structure; ensure compliance with regulations, guarantee secure payments; and recruit your first partners.
  

What is a multivendor marketplace?

A multivendor marketplace is a digital platform that connects buyers and sellers of goods or services. It acts as a trusted intermediary between the two parties, centralizing sellers’ offers and presenting them to buyers.

The multivendor marketplace model is based on a relationship between the following three parties:

• The marketplace provides the technical infrastructure that hosts sellers’ offers and makes them available to end customers. The marketplace typically handles the listing of offers, advertising on the platform, and ensuring transactions are secure.
  
• Sellers set their own prices, manage their inventory, and ship orders. The marketplace enables them to increase their visibility and expand their customer base without the complexity of managing a proprietary ecommerce site.
  
• End customers benefit from a wide array of products and services at competitive prices. They can easily browse offerings from multiple sellers and consolidate their purchases in one place.
  

Examples of marketplaces in France include Fnac, Darty, Boulanger, Cdiscount, and La Redoute.

What is the legal framework for a multivendor marketplace in France?

The legal framework for a multivendor marketplace depends on the scope of its role in the business relationship. Whenever a marketplace plays an active role in presenting, promoting, or optimizing offers on its platform—or collects funds on behalf of third parties—its operations become subject to a strict and nuanced regulatory framework.

This multifaceted framework includes both French laws and European directives, including:

• EU Regulation 2019/1150 on platform-to-business (P2B) relations: Requires the framework of a contractual relationship with sellers and full transparency on the criteria used to rank offers, as well as the grounds for suspension or termination
  
• French Consumer Code and the EU Omnibus Directive: Requires the drafting of general conditions of use (CGU) that clarify the respective roles and responsibilities of the marketplace and sellers
  
• Security and Regulation of the Digital Space (SREN) Act, derived from the Digital Services Act (DSA): Requires platforms to verify the identities of sellers before displaying their offers, ensure algorithm transparency, and use responsive tools to prevent illicit content
  
• General Data Protection Regulation (GDPR): Governs the collection, processing, and security of personal data belonging to both buyers and sellers
  
• The revised Payment Services Directive (PSD2), transposed into the French Monetary and Financial Code (CMF): Regulates financial flows passing through the platform and requires funds to be held in escrow via a segregated account
  
• The seventh revision of the EU Directive on Administrative Cooperation (DAC7), transposed into the French General Tax Code (CGI): Requires platforms to report annually to the tax authorities the revenue generated by their sellers, as a measure to combat fraud
  
• Digital Markets Act (DMA): Targets very large platforms (designated as “gatekeepers”)
  

How do you choose the right marketplace and monetization model?

To choose the marketplace and monetization model that’s the best fit, you need to analyze your target audience, the nature of your offering, your operational capacity, your budget, your long-term goals, and market trends. Note that the model you choose can affect the platform’s popularity and profitability.

Marketplace models

There are three major marketplace categories that differ by target audience: business-to-business (B2B), business-to-consumer (B2C), and consumer-to-consumer (C2C).

The B2B model facilitates commerce between businesses. It’s used primarily for procurement, wholesale purchasing (particularly of raw materials), and sourcing of specialized services. This multivendor marketplace model requires a high level of proficiency in managing B2B relationships, which are often complex.

The B2C format connects professional sellers with individual consumers. This is the most widespread model, but also the most competitive, focused on a seamless user experience. Examples include Amazon, Cdiscount, eBay, and Fnac.

C2C marketplaces, such as Vinted, leboncoin, and BlaBlaCar, allow individuals to trade directly with one another. This model relies primarily on community trust and ease of use.

Beyond the target audience, the structure of a multivendor marketplace depends on the nature of its catalog and its positioning. For instance, a platform might be designed exclusively for products (such as La Redoute) or, conversely, for services (such as Airbnb, Uber, Doctolib, and Malt).

At the same time, a platform could offer a wide range of categories (much like Cdiscount and Rakuten), or it could target a specific niche (such as fashion, technology, or construction) to establish itself as an expert in that sector. In France, ManoMano, Boulanger, and Back Market are examples of specialized marketplaces.

There are also hybrid marketplaces that sell their own products in addition to those of their partner sellers.

Monetization models

The business model of a multivendor marketplace determines how it generates revenue for its service. Marketplaces can use multiple monetization models at once, including:

• Commissions: The marketplace charges a percentage or a fixed fee on each transaction made through it. This model generates revenue in proportion to sales volume. It’s particularly well suited for marketplaces that handle a high volume of transactions.
  
• Subscriptions: Sellers or buyers pay a fixed fee each month or year to access the platform. This model offers marketplaces predictable recurring revenue—which can help manage liquidity—and builds a base of loyal users. However, it can also discourage users who are hesitant to subscribe.
  
• Listing fees: The marketplace charges sellers for each listing published on the platform. This ensures revenue as soon as a listing goes live (without waiting for a sale), but it also creates a significant barrier to entry.
  
• Fees for advertising and additional services: The marketplace charges for advertising or offers ancillary services (e.g., integrated shipping, gift wrapping, insurance) to boost revenue. This strategy is often used by mature platforms.
  

What technical tools are available for creating marketplaces?

There are three types of technical solutions for creating a marketplace: software-as-a-service (SaaS), open-source software, and custom software. SaaS solutions are cloud-hosted and accessible via the internet. They’re useful for getting started quickly with ready-to-use features. The interface can be customized, but you’re still limited to what the solution offers.

Open-source software, on the other hand, is developed in collaboration with other users. It offers more flexibility than SaaS and a high level of technical control: you have access to the code, which is ideal for highly skilled technical teams. However, you are responsible for hosting, maintenance, and security costs.

Custom-built software offers maximum flexibility, but at a high cost and with a long startup time. It’s best suited for unique, complex projects that require a tailored solution. Custom software is recommended only for operators with a substantial development and maintenance budget.

Regardless of the technical solution you choose, the user experience (for both buyers and sellers) must be at the heart of the decision. It’s key to prioritize user-friendliness, simplicity, accessibility, and seamlessness. Features must be robust and high-performing, ensuring fast navigation for buyers and intuitive back-end management for sellers.

Key marketplace features include:

• An efficient search engine with advanced filters
  
• Detailed product and service listings that include price, description, and availability
  
• A customer review system
  
• A secure checkout and payment process
  
• A real-time order tracking tool
  
• A reliable, intuitive seller interface with a simple registration process, dedicated seller profiles, and performance dashboards
  

How to manage multivendor payment flows

To manage multivendor payment flows in a compliant manner, marketplaces must be certified by the French Prudential Supervision and Resolution Authority (ACPR) to collect funds on behalf of third parties (a lengthy, costly process), or use an ACPR-certified payment service provider (PSP) (the most common solution). Under certain conditions, a marketplace can obtain exemption from certification, but this option is very rare in practice.

As a trusted intermediary, a marketplace must ensure transaction security and protect payment data. Its role consists of verifying sellers’ identities via a process called Know Your Customer (KYC) or Know Your Business (KYB), collecting funds on behalf of sellers, segregating the collected funds from its own cash reserves, and then disbursing the balance to the various sellers after deducting its commission (if its business model so provides).

What are the steps in creating a multivendor marketplace?

From planning to launch, creating a multivendor marketplace requires careful consideration. Here are the steps to setting your platform up for success:

• Define the concept and market positioning
  First, decide what your platform will sell and identify the target audience. Develop your value proposition by specifying what sets you apart from your competitors. Then, choose the marketplace model best suited for your offering and target audience.
  
• Conduct market research
  Next, study the competition, the expectations of sellers and buyers, market trends, and purchasing behaviors. This information will help you better meet the needs of your target audience and refine your differentiation strategy.
  
• Choose a business model
  The next step is to select your marketplace’s revenue model. Will you generate income through sales commissions or subscriptions? Do you plan to charge for ancillary services or listing fees?
  
• Choose a legal structure
  Choosing the right legal structure is important, as it determines your business’s tax regime, filing obligations, and governance methods. The legal structure needs to fit your current situation while also supporting your future growth. A single-shareholder simplified joint-stock company (SASU) is a good fit for a solo entrepreneur, while a simplified joint-stock company (SAS) is often the preferred choice when launching with multiple partners.
  
• Establish a projected budget
  Before committing, it’s important to determine the costs associated with building and maintaining the platform, as well as your marketing budget. Be sure to include expenses related to technology and legal compliance.
  
• Choose a technical solution
  Your choice of technical solution will depend on your budget, requirements, available expertise, and timeline. The solution must ensure the smooth operation of your marketplace and simplify the daily experience for your users.
  
• Implement a reliable payment process
  Processing multivendor transactions requires the integration of a secure payment system that offers buyers multiple payment options. To satisfy legal obligations related to managing funds on behalf of third parties, you must either obtain ACPR certification or use an authorized PSP like Stripe Connect.
  
• Ensure legal compliance
  Often overlooked during the early stages of a business, legal compliance is fundamental to your platform’s success. You must draft your company bylaws and ensure that your legal documents—general conditions of use (CGU), general conditions of sale (CGV), and privacy policy, as well as your partner contracts (e.g., for payment or logistics services)—are finalized and signed. Do not overlook the obligations related to personal data protection, transaction security, and the annual reporting of seller revenue.
  
• Recruit and onboard sellers and service providers
  A simple registration process, rigorous vetting, easy listing of products, reliable seller support, and performance dashboards are all key to attracting your first partners. It’s important to select trusted sellers and service providers to validate your concept and bring it to life.
  
• Create a responsive customer support team
  You must also consider the buyer experience. Establishing a responsive customer service team and a clear framework for resolving disputes will help streamline the purchasing process and improve the customer experience.
  
• Launch
  The final step in creating a multivendor marketplace is to create a launch and marketing strategy. To achieve this, you can leverage social media, targeted advertising, search engine optimization (SEO), welcome offers for early adopters, or partnerships with influencers. Integrating a loyalty program from the outset can also encourage repeat purchases on your platform.
  

How much does it cost to create a multivendor marketplace?

The cost of developing a multivendor marketplace varies depending on its technical and legal requirements. A SaaS solution with basic features can cost a few hundred euros per month, on top of installation and customization fees (typically ranging from €20,000 to €80,000). The cost of robust, scalable, custom-built architecture often starts around €50,000 to €150,000 and can reach several million euros for large-scale projects.

You must also factor in the costs of legal compliance, hosting, maintenance, and marketing, as well as any commissions charged by the PSP (if applicable).
