To make a marketplace website, validate a real need on both the buyer and seller side, choose how the marketplace earns money (commission, listing fees or subscriptions), pick a build route (a marketplace SaaS, WordPress with a multi-vendor plugin, or custom code), set up split payments and seller verification, then launch a minimum viable product and improve it with real usage data.
Key Takeaways
- An online marketplace is a two-sided platform: the operator connects third-party sellers with buyers and usually earns a fee on each sale.
- Poor product-market fit and running out of money are among the most cited reasons startups shut down, so validation and a clear revenue model come before features.
- Ready-made tools lower the cost of a first version: Sharetribe plans started at $39 per month as of October 2026, and the Dokan plugin turns a WooCommerce store into a multi-vendor marketplace.
- Marketplace payments need a split-payment service (for example Stripe Connect) that pays sellers and keeps the platform fee.
- Marketplaces carry legal duties to verify sellers, such as the US INFORM Consumers Act (in force since June 27, 2023) and the EU Digital Services Act.
Right now, you might have seen your share of the online marketplaces, which start with a promising idea but generally fail to generate proper traction and end up closing down shortly after.
There are several common reasons for that: no real market need, an unsustainable business model, poor software choices, weak marketing, and running out of money before the marketplace gains traction.
How to Develop A Marketplace Website
Here, you will come to learn ways to start your marketplace business. Right from covering the market research to choosing the right business model, selecting proper software, and launching your marketplace, there are many steps to focus on. But before any of that, it is better to start with the basics.
Start by researching the target marketplace
To answer your question on how to build a marketplace website, this guide walks through the core steps below. Aimprosoft, a software development company, has also published an article on the topic, linked above.
Whether you are here to create a marketplace website from scratch or switching from a regular online store to a multi-vendor marketplace, you have to complete your market research first.
- Starting an online marketplace without a clear understanding of the target audience and the market’s needs is a poor way to start a business.
- A viable marketplace needs a clear understanding of both sides of the market. Learn who your buyers and sellers are, what they need, and which solutions they use today.
- Furthermore, you need to assess the market. It is your job to understand what you are getting yourself into before you start working on it.
Selecting the right business model
Many startups fail because they build something no one is looking for: in a CB Insights analysis of 431 venture-backed companies that shut down since 2023, poor product-market fit was cited in 43% of cases. Another common reason is when a business runs out of cash, which the same analysis found in 70% of shutdowns, usually as the final cause rather than the root problem. Creating a valuable product that people need is not the end of the story. You also need a way to make it profitable in the long run.
Whatever your industry or background, design a viable business model before you build the website. How the marketplace makes money depends on the revenue streams you choose, such as sign-up fees, subscriptions, insertion or listing fees, and selling fees (commissions).
Plan out for the marketplace operations
Building a working marketplace website is one thing; running a marketplace business successfully is another. Even a regular e-commerce business gets complicated because of the tasks that must be handled every day.
- Marketplace operations are harder because the platform serves two sides, buyers and sellers, so plan for the challenges you will face daily.
- You have to manage sellers every day so that orders are fulfilled and delivered on time.
- As the marketplace owner, you also manage the product catalog: listing quality, categories, prohibited items and the inventory sellers show online.
- Plan your online payment processing. carefully. Marketplace payments are more complicated than payments in a regular store because the platform collects money from buyers, keeps its fee, and pays the rest out to sellers.
Outline the significant marketplace features
If you build an online marketplace with features users do not need, you waste time and money. Some marketplace projects spend so long in development that they never launch.
The primary advice is to start with the essentials and then launch one MVP early. Then improve the platform as the business grows and the requirements become clearer. Essential features fall into three sides: the buyer side (search, listings, checkout, reviews), the seller side (sign-up, listing management, orders, payouts), and the admin side (seller approval, moderation, commissions, disputes and reporting).
Add advanced marketplace features as you grow
Advanced marketplace features belong after the essentials work and real users show which ones they need. They help a growing marketplace scale, but they rarely decide whether the first version succeeds.
Typical additions include reporting tools, advanced marketing and selling features, your own mobile apps, and integrations with third-party e-commerce services.

What Is an Online Marketplace?
An online marketplace is an e-commerce website where multiple third parties offer products or services, while the marketplace operator runs the platform and usually processes the transactions. Amazon, eBay and Taobao are retail examples; Upwork is an example for freelance services. Unlike a single-vendor online store, a marketplace does not need to own stock: its job is to bring buyers and sellers together and make trading between them safe.
Types of marketplaces
| Type | Who trades | Examples |
|---|---|---|
| B2B (business-to-business) | Companies buying from suppliers, often in one product category | Industrial and wholesale supply platforms |
| B2C (business-to-consumer) | Businesses selling to individual shoppers | Amazon, Taobao |
| C2C (consumer-to-consumer) | Individuals trading with each other through an intermediary | Peer-to-peer and sharing-economy platforms such as Airbnb |
| Service marketplace | Freelancers or providers selling time and skills | Upwork |
How Do Marketplace Websites Make Money?
Marketplace websites make money mainly by charging sellers, buyers or both. Most combine two or more of the models below, and the right mix depends on how often transactions happen and how much value each one creates.
| Revenue model | How it works | Works best when |
|---|---|---|
| Commission (selling fee) | A percentage of each sale goes to the platform | Transactions happen on the platform and payments run through it |
| Listing or insertion fee | Sellers pay to publish each listing | Listings are valuable on their own, such as property or vehicles |
| Subscription | Sellers or buyers pay a recurring fee for access or extra tools | Users trade often and want predictable costs |
| Sign-up fee | A one-time fee to join | Membership itself is worth paying for |
| Featured listings and ads | Sellers pay for more visibility | The marketplace already has steady traffic |
Which Platform Should You Build a Marketplace On?
A marketplace can be built on a hosted marketplace platform, on WordPress with a multi-vendor plugin, or with custom code. The table compares the three routes as of October 2026; check each vendor’s current pricing before you commit.
| Build route | Example | Cost and effort | Best for |
|---|---|---|---|
| Hosted marketplace software (SaaS) | Sharetribe | Build plan $39 per month; Live plan $199 per month billed yearly or $259 billed monthly; 14-day free trial; no Sharetribe transaction fee, but Stripe charges its own processing fee | Testing an idea quickly without developers |
| WordPress and WooCommerce with a multi-vendor plugin | Dokan (30,000+ active installations of the free version on WordPress.org) | Hosting, themes and premium add-ons cost extra; you maintain updates and security | Teams that already know WordPress and want control |
| Custom development | Your own code and payment integration | Highest cost and longest timeline | Unusual workflows or scale that packaged tools cannot handle |
If you choose WordPress, the guide on deploying an e-commerce site on WordPress covers the store setup that a multi-vendor plugin builds on. For general planning, see what to know before developing an e-commerce website.
How Do Marketplace Payments Work?
Marketplace payments work by splitting each order: the buyer pays the platform, the platform keeps its fee, and the seller receives the rest as a payout. A standard checkout for a single store cannot do this on its own, so marketplaces use a payment service built for platforms.
Stripe Connect is one widely used option. According to Stripe’s documentation, it lets a marketplace collect payments from customers and automatically pay out a portion to sellers or service providers, and it includes tools to collect and verify the information required for each connected seller account. Sharetribe notes that Stripe’s processing fee is typically around 1.5% to 3% of the transaction. For a wider look at gateways, read how a payment gateway affects website business growth.
The 2Checkout service linked in the original article was acquired by Verifone, which announced the deal on September 8, 2020; the service has since been increasingly offered under the Verifone name.
What Legal Rules Apply to Marketplace Websites?
Marketplace websites have legal duties that a single-vendor store does not, mainly around verifying who the sellers are. The two best-known examples are below; this is general information, not legal advice, so check the rules in every country where you operate.
- United States, INFORM Consumers Act: in force since June 27, 2023. According to the Federal Trade Commission, a high-volume third-party seller is one with 200 or more separate sales and $5,000 or more in gross revenue in any continuous 12-month period during the previous 24 months. Marketplaces must collect such a seller’s bank account, tax ID and contact details within 10 days, verify them, and have sellers certify the information at least once a year. Sellers with $20,000 or more in annual gross revenue on the marketplace must have their name, physical address and contact information disclosed to buyers. The FTC lists civil penalties of $53,088 per violation as of January 2025.
- European Union, Digital Services Act (DSA): applies to all online platforms in the EU since February 16, 2024. The European Commission states that marketplaces must verify and display sellers’ contact details and make reasonable efforts to carry out random checks on products sold on their service. Fines can reach up to 6% of global annual turnover.
Privacy, consumer-protection, tax and payment rules also apply. Visible seller verification and clear policies help build buyer confidence, a theme covered in why trust badges matter for e-commerce.
Step-by-Step Checklist to Launch a Marketplace
- Pick a niche and confirm that buyers and sellers both have a problem your marketplace solves.
- Choose the revenue model (commission, listing fee, subscription or a mix) and check that the numbers cover your costs.
- Choose a build route: SaaS, WordPress with a multi-vendor plugin, or custom development.
- Define the minimum features for buyers, sellers and admins, and leave everything else for later.
- Set up split payments, seller onboarding and seller verification.
- Write the terms of service, seller policy, prohibited-items list, refund and dispute rules, and privacy policy.
- Recruit a first group of sellers before opening to buyers, so the marketplace does not launch empty.
- Launch the MVP, measure where users drop off, and add features based on that evidence.

Frequently Asked Questions
How much does it cost to build a marketplace website?
The cost of a marketplace website depends on the build route. As of October 2026, hosted software such as Sharetribe started at $39 per month for its Build plan, with the Live plan at $199 per month billed yearly. A WordPress build adds hosting and plugin costs, and custom development costs the most.
Can I build a marketplace website without coding?
Yes, a marketplace website can be built without coding. Hosted marketplace platforms such as Sharetribe and WordPress plugins such as Dokan, which works with WooCommerce, provide seller accounts, listings and checkout out of the box.
What is the best business model for a marketplace?
Commission on each sale is a common marketplace business model because the platform earns only when sellers do. Listing fees suit high-value listings, and subscriptions suit users who trade often. Many marketplaces combine two or more models.
What features does a marketplace MVP need?
A marketplace MVP needs buyer search and checkout, seller sign-up and listing management, split payments with seller payouts, reviews, and an admin panel for approving sellers, moderating listings and handling disputes. Advanced features can wait until real users ask for them.
Do marketplace owners have to verify sellers?
In many places, yes. In the United States the INFORM Consumers Act requires marketplaces to collect and verify information from high-volume third-party sellers, and in the European Union the Digital Services Act requires marketplaces to verify and display sellers’ contact details.
