eBay is a globally recognized trend that has achieved its marketing position by combining its online auction model with buy-now items. This solves the issue of price discovery and liquidation for inventory of uncertain value. The dual business model maximized profit potential for sellers while streamlining its revenue with a combined fee-based model. In this article, we discuss how to create an online marketplace like eBay.
-
Competing with an eBay-like marketplace requires implementing a vertical niche specialization to attract the first vendors.
-
Consider implementing both auction and fixed-price models, but test and validate which one brings more conversions.
-
Combine Buyer Protection Guarantee, dispute resolution mechanism, and feedback ratings to build and maintain the platform’s trust and credibility.
What Type of Website Is eBay, and How Does It Work
eBay is a global platform that continuously integrates buyers and sellers, representing a multi-vendor marketplace. By intertwining online auction and fixed-price models, the website enables sellers to maximize the sale price of every item, ensuring robust revenue growth.

Multi-Vendor Marketplace Explained
A multi-vendor platform operates as a host, not a retailer. The platform provides essential technical infrastructure, including listings, payment processing, and dispute resolution, to connect buyers and sellers. The vendor remains responsible for storage, packaging, handling logistics, and shipping.
How eBay's Business Model Operates
eBay operates via the fee-based business model, implying the platform earns revenue without owning physical goods. The fee structure includes the following types:
-
Insertion or Listing Fees: a small portion of a non-refundable fee for placing the item. The fee is imposed even if the good is not sold. These fees help cover server and maintenance costs.
-
Final Value Fees: this relates to the commission eBay takes when the item is sold (including shipping). This key revenue-generating fee is categorized and calculated differently for each item type.
-
Promoted Listing: acting like an internal-system revenue stream, eBay enables sellers to pay an extra fee for item promotion to achieve higher placement in search results.
-
Managed Payment Fees: eBay takes a small payment portion for the internal payment processing, as it doesn’t rely on third-party payment processors.
Marketplace vs Auction: What's the difference?
Both marketplace and auction models can coexist within platforms like eBay, but their dynamics in determining the final product price and sale completion are quite different.
Marketplace Business Model
The marketplace model is standard for retail e-commerce, which means that the client can buy the item instantly. They don’t have to place a bid and wait for results, as in the auction model. These are the key determinations of the marketplace model:
-
Final Pricing: the seller sets a fixed price, which is non-negotiable or set as a specific ‘Best Offer’ option.
-
Transaction Speed: The transaction is complete nearly instantly when the buyer agrees to pay the determined price.
-
Competition: customers don’t compete with each other for the specific item. The competition revolves around inventory and time (whether the vendor has the item available).
-
Marketplace Model Suitability: the model is suitable for mass products, especially for vendors that prioritize sales volume and price consistency.
Auction Model
In contrast to the marketplace model, an auction is about the competition between clients for the final selling price to receive the product.
-
Price Setting: the price is determined by the highest competitive bid placed on the auction. One of the central factors is the expiration of time. The process starts with the minimum bid.
-
Transaction Speed: transaction speed is delayed as the sale can be completed after 3, 5, or 7 days, and only if the specific customer’s bid wins.
-
Competition: buyers compete against each other by placing bids. The competition is the core price driver.
-
Auction Model Suitability: rare items, collectibles, bulk used goods, and items with uncertain or variable market prices.

Why Build a Website Like eBay in 2025?
The power of eBay on the global market is indisputable, yet the platform creates opportunities for new entrants. Building a marketplace in 2025 is about switching to the contemporary e-commerce trends to cover specialized, high-margin market segments, as well as solve eBay’s pain points.
Focusing on Niche Specialization & Expertise
One of the central drivers to make a website like eBay today is the potential for vertical specialization. eBay’s breadth makes it generic, implying that modern consumers are more likely to prefer platforms with deep domain expertise and guaranteed quality within a specialized niche.
Focus on Authenticity & Trust
The authenticity guarantee might prove niche expertise and the platform’s narrow specialization if it were dedicated solely to a certain niche. This would enable a higher level of vetting and specialized customer service that the traditional marketplace cannot ensure. Despite focusing on a niche, the platform could implement eBay-like marketplace and auction models.
Emphasis on Personalization
Niche marketplaces contribute to fostering the community. The platform can tailor features like search filtering and marketing directly to highly specific language and customer base needs (e.g., collectible coin metrics). The high level of personalization increases its recognition, loyalty, and customer retention.
Increased Margins
Providing specialized services like authentication, expert appraisal, and escrow of high-value goods enables niche platforms to set and justify higher transaction fees.
Addressing Modern E-Commerce Trends
New platforms can leverage contemporary technological advancements and business models to differentiate themselves from eBay’s aging infrastructure and a set fee structure.
Personalized Discovery
The new eBay-like platform can embed an advanced AI and machine learning mechanism to achieve maximum search personalization. This approach shifts from a simplistic keyword search, enabling clients to experience better matching and access unique inventory that might frustrate collectors on massive sites.
Integrating Social Commerce
New platforms can integrate social media-relevant features like live auctions, influencer endorsement, and user-generated content. This proactive approach can increase the dynamics in the shopping experience, stimulate engagement, and present the possibility for the items to go viral as compared to the static listing page.
Payment & Finance Integration
The new eBay-like marketplace can seamlessly incorporate modern fintech options like Buy Now, Pay Later (BNPL), as well as integrate blockchain and smart contract support to improve access for traditional users and crypto-savvy customers with different income levels.
Solving eBay’s Pain Points
Although eBay takes one of the leading positions in global e-commerce, the launch of the new platform can contribute to fixing its model’s weaknesses.
Optimizing Dispute Resolution
Despite the presence of the eBay dispute resolution system, it’s criticized for favoritism and slow performance. The new platform can deliver accelerated and clearer dispute resolution with rigid buyer protection policies. To be specific, businesses can leverage blockchain and smart contracts to achieve a strategic advantage. The platform can ensure fast, fair, and automated dispute resolution by coding the predefined buyer protection system rules into a smart contract.
Seller Costs Minimization
A new platform can offer a lower flat-fee structure or performance-based incentives for the high-volume traders while keeping eBay’s combined fee structure serving small businesses.
UX Optimization
Despite the global recognition, eBay’s interface remains dated, which can be a strategic advantage for the new platform. Demonstrating a clean, mobile-first, and intuitive user experience that minimizes friction can influence conversion rates considerably.
Step-by-Step Guide: How to Create an Online Marketplace Like eBay
In order to create a marketplace like eBay, it’s critical to understand the market to define what niche to enter and what specific feature set the application will contain. This will determine how the platform will attract the target audience and increase conversion.
Step 1: Find and Validate Your Marketplace Idea
The first critical step you need to take when developing a website like eBay is finding and validating the marketplace idea that would detect and solve a real problem. Since it’s impossible to compete with eBay on breadth, or the overall inventory, consider competing in depth or specialization. This is about identifying the underserved niche where a dedicated platform can demonstrate a specialized experience, as compared to the trade giant.
Identify & Define the Niche
Shift from the general and broad category to the highly specific vertical. For instance, vintage mid-century classic furniture from England. You have to analyze the fragmentation of where the buyers and sellers are struggling to connect. That’s basically a market where the inventory is unique with uncertain value, while the trust level is low.
Then, it’s time to define the target audience. Who exactly are your buyers and sellers? Are they collectors? Casual users? Or professional dealers? This point is crucial as it enables you to solve the specialized pain points eBay might lack.
Validate the Pain Points
Identify what real frustrations your eBay-like marketplace is going to solve? Without validating their essence, your platform won’t get the traction. For instance, your platform might contribute to solving:
-
Trust & Authenticity Issues: if the market is at risk of counterfeits (especially for luxury items), then the platform’s core value should offer guaranteed authentication services.
-
Logistics & Shipping Problems: you must determine whether the sellers deal with challenging inventory, including the large, fragile items or fine art that are difficult to ship internationally. If so, your platform must integrate a unique, specialized shipping solution currently unavailable on eBay.
-
Valuation Uncertainty: define whether your items present a fluctuating value. If so, your platform can integrate an auction model combined with an expert appraisal or price discovery tools.
Perform Competitor Analysis
You have to define how your competitors serve the selected niche by identifying gaps and determining your differentiation. In gap identification, you have to point out what services are present and missing. eBay offers a general feedback score, while your platform can focus on a public and verifiable provenance record for each item.
Idea validation can be wrapped up only if you can define how your platform’s specialized features, lower fees, or exquisite UX will compel users to switch from their current preferred solutions.
Step 2: Solve the Chicken-and-Egg Problem
The chicken-and-egg paradox is a primary issue for any two-sided marketplace. Buyers will not utilize your marketplace until you have sellers; sellers will not list their items until they know you have customers. To overcome this dilemma, you will need to focus on developing one side of the marketplace first, so that the first side can attract an initial batch of users.
Strategy 1: Attract the Supply (Sellers)
Attracting suppliers is the primary strategic approach to resolving the dilemma. Inventory is the backbone of any marketplace that can serve as an element of differentiation from the competitors.
-
Optimize Fee Structure: minimize fees or implement discount listing and transaction commissions for the first set of anchor sellers. This reduces the risk of refusal, enhancing their interest in investigating a new platform.
-
Ensure Access to Exclusive Tools: provide sellers with access to advanced elements they won’t find on eBay, including specialized inventory management, streamlined custom shipping solutions, or free access to authentication or appraisal services.
-
Focus on Initial Attraction: manually enroll a small number of high-quality and high-value sellers. High-value sellers can include some well-known resellers within a collectibles niche who have unique inventory and, therefore, will attract the first batch of buyers and will ultimately give your marketplace legitimacy.
Strategy 2: Attract the Demand (Buyers)
Once the minimum, high-quality inventory is secured, you can shift the focus from supply development to demand development with some buyer rewards for early sellers.
-
Offer Discounted Shipping/Incentives: lower the barrier to entry by offering users discounted shipping for their first purchase.
-
Start with a Significant Event: Instead of launching the marketplace on Google Play or the App Store, start with a specific date event. Why not create a buzz with a live auction on the limited-edition drop of the specific product?
-
Targeted Outreach: if it’s a niche eBay-like platform, implement targeted advertising and content marketing to reach the most motivated consumers by placing ads in specialized collector forums.
Step 3: Define Core Features for Sellers, Buyers, & Admins
When idea validation and solving the chicken-and-egg problem are over, it’s time to define the eBay-like platform’s Minimum Viable Product features. Since the marketplace is going to be two-sided, you have to identify the necessary tools for three categories: Sellers, Buyers, and Admins.
Principal Features for Sellers (the Supply Side)
Sellers need tools that would assist in minimizing the administrative time and simplifying shipping, while enabling them to maximize profitability.
Principal Features for Buyers (the Demand Side)
On the other hand, buyers are interested in tools that would power trust, simplify discovery, and reduce risks.
Principal Features for Admins
Admins are responsible for platform control to support safety by handling its financial health and enforcing policy.
Step 4: Select Tech Stack or Platform (Custom vs. SaaS vs. No-Code)
The selection of the technological foundation is the fundamental decision that will determine the upfront cost of the overall marketplace, including time to market, scalability, and performance integrity. In order to build a website like eBay, the decision is made whether you prioritize flexibility (custom) or development speed (SaaS/No-Code).
Custom E-Commerce Solution
Developing a website like eBay requires the highest upfront investment, especially for sophisticated features like AI. That’s due to the potential for the highest scalability. Additionally, the business will be the owner of the final product, implying complete ownership of every element. This is critical for highly specialized features like blockchain integration, complex bidding logic, and unique shipping integrations.
The overall time to market will be longer than SaaS, based on the platform complexity and prior MVP development. Finally, businesses that aim to target the high-value specialized niche and are interested in durable growth can apply the custom software development approach.
SaaS
Software as a Service or SaaS platforms, including CS-Cart Multi-Vendor, present a pre-built marketplace infrastructure that you can utilize to cut development time. A SaaS solution requires a medium initial cost; however, it operates within the monthly/transaction fees. This option fits controlled budgeting, but can be compromised when the volume grows. Scalability is at the medium level when speaking about middle-level platform complexity. The high-frequency and real-time auctions might degrade the performance.
Pay attention to the moderate flexibility, as you’ll have to sacrifice brand uniqueness. Features have to fit the platform’s existing models. The buy-now model support is flexible, yet the auction mechanics remain limited. SaaS solutions fit startups that prioritize time over unique features, aiming to target less specialized niches.
No-Code Option
The no-code opportunities, indeed, enable businesses to build a marketplace. However, it will be suitable only for pre-MVP prototyping or exclusively for a highly specialized and narrow niche that will operate within a low-traffic environment. Keep in mind that this development option does not support the auction model, which will only mimic the eBay-like platform, but will not support its full functionality.
The no-code approach is fast in deployment, but compromises on flexibility as integrating complex commission tiers or managed payments will be technically complicated. It’s appropriate to use the no-code option for idea validation before transitioning to custom development or a SaaS solution.
Step 5: Build a Marketplace MVP (Must-Have Features First)
In the MVP stage, the business representatives have to shift from the validated niche idea to the practical realization of the functional platform. The Minimum Viable Product has to facilitate the principal function between the merchant and client: transaction. Other nice-to-have and advanced elements, like AI, are not reasonable at this stage.
The MVP development has to ensure that the platform can solve the principal pain point of the user by integrating the core workflow, including:
-
Item Listing: the merchant can place inventory seamlessly.
-
Discovery Flow: the client can find the required items with ease (basic keyword search).
-
Transaction: the client can pay securely, while the vendor receives payments.
-
Trust: the embedded rating mechanisms for both parties to assess the cooperation.
Step 6: Design Seamless UX for Trust and Retention
The next UI/UX Design phase focuses on transforming business requirements into a functional and easy-to-use interface. This step matters to maintain trust and impact conversion rates.
The UI/UX Design covers:
Wireframing: a structural blueprint of all pages, including landing, search results, listing creation, error occurrence, etc., to underline flow and element placement.
Prototyping: validate the design before development by generating an interactive mockup to check the user’s flow.
UI Design: incorporating the brand’s unique visual identity within the specific color palette, fonts, and iconography for internal design validation. This step is essential so that the developers can remain consistent while crafting the core.
Mobile-First Approach
The design process should start with adapting to the smallest screens, progressively to tablets, and web variants. The mobile-first approach is about prioritizing the most critical elements, like bidding or checkout, that should result in a clear desktop experience later.
Finally, interfaces should be designed with a simplified navigation flow for critical actions. A minimized number of steps with effective responsiveness will directly stimulate operational simplicity and maintain retention.

Step 7: Launch and Onboard First Sellers
When crafting the MVP and establishing the core transaction functionality, it’s time to shift the platform from developing to operating. This phase focuses on a strategic and controlled launch to validate the overall platform and onboard the vendor segment.
Strategic Launch
Focus on a soft launch instead of the direct encompassing targeting, as it’s critical to attract the core sellers first. Consider Alpha/Beta testing, aiming to check how both sellers and buyers interact with the platform. This enables early detection of bugs and evaluating the payment flow before going public.
Then, list the top inventory, to attract the first wave of critical buyers. Finally, narrow the scope and announce the launch within the specialized communities, like industry groups or specialized social media. This is critical to attract the target audience specifically, to gain initial recognition.
Premium Onboarding
In order to capture the attention of target vendors, you have to focus on highly personalized seller onboarding. This can include the abovementioned lower fees, access to early features, and simplified shipping. That’s because it’s essential to recruit vendors manually by solving their key pain points.
Reconsider the initial setup payment approach. Enable sellers to use the platform for free, which will lead to uploading dozens of photos and listing numerous items. Friction removal is central at this point.
Finally, summarize onboarding with time-limited and attractive incentives, including free three-month trial or guaranteed sale threshold. This can be presented in the form ‘We’ll credit fees if you don’t sell $X within a 3 months threshold.’ This approach will stimulate retention, building trust and loyalty.
Step 8: Test, Optimize, and Gather Feedback
In the final stage, you’ll have to use the real-world data to define the overall bottlenecks in the platform’s performance, and check whether the UX flow runs as intended. This is an ongoing and cyclical process, required to ensure smooth website operability.
Testing & Optimizing the Core Transaction Flow
That’s about checking the overall fundamental actions, including listing, searching, bidding/buying, and checkout. The purpose is to eliminate even the slightest point of friction to prevent any drop-offs and reputation loss.
A/B testing can be a central approach to decoding clients’/buyers’ preferences about button placement, pricing models (auction/buy now), and to check which one generates the highest conversion. Apply tools like Optimizely and VWO.
Monitoring performance is a critical part of testing, especially on mobile devices, as it’s about the pace of content and processes loading. This is critical to keep retention. Apply tools like New Relic or Google PageSpeed Insights.
Finally, error reporting mechanics is central to capturing log errors during transactions and checkout. Apply Firebase Crashlytics.
Gathering Behavioral and Qualitative Feedback
Qualitative tools will indicate why the specific issue is happening. Don’t ignore behavioral tracking and interviews, as they illustrate insights into the actual user’s interaction with the platform.
Conduct behavioral tracking to visualize how clients navigate the site and detect the drop-off points and whether the niche-specific features function in a correct manner. Use Hotjar, Microsoft Clarity, or Mixpanel.
Perform user interviews to gain profound insights into vendors’/users’ experience with the platform, as compared to eBay. Apply tools like Zoom or UserTesting.
How Much Does It Cost to Build a Marketplace Like eBay?
The cost of building a marketplace like eBay is determined by its complexity and overall approach to development. The approximate cost of creating a middle-level platform like eBay ranges from $108,000 to $215,000+.
MVP Development Costs
First of all, let’s clarify the MVP development costs. Despite the support of core functions, the MVP can include sophisticated features if speaking about an enterprise-grade platform.

The Overall Platform Development Cost
When it comes to the overall full-fledged platform development, the cost will be calculated based on the development stages.
In-House & Outsourcing Team
Finally, don’t forget that creating an eBay-like marketplace requires investment in the development team. Despite the complexity level, the overall process of development can be shifted to the outsourcing vendor. This presents a strategic advantage, including cost reduction and closing the talent gap.
How to Scale Your Marketplace After Launch
Launching an efficient marketplace in the domestic market is an undeniable achievement. Nevertheless, if scaling up, the platform has to keep retention from the global sellers and clients, requiring expanding the user base, strategic geographical growth, and investment in smart technology.
Growing Seller Base
The primary driver that will stimulate user flow and behavior is the inventory, or the number of items available on the marketplace. Scaling of an eBay-like website requires aggressive growth and attraction from the seller side.
Targeted Onboarding
Focus on strategic recruitment and onboard specific types of sellers that could close the immediate product gaps or secure high-value inventory. This can include onboarding small businesses or boutique retailers.
Minimize Seller Friction
Leverage the potential of simplified listing and payment processes. Add tools like bulk listing options or automated inventory management to improve affordability for sellers.
Leverage Exclusivity
Include opportunities like premium support, early access to features, and tiered commission structures to motivate high-volume sellers to prioritize your platform over the competitors’.
Marketing & SEO Optimization
A marketplace should build organic traffic and strong brand visibility beyond paid advertising.
SEO for Long-Tail Keywords
Streamline product pages by including the long-tail keywords (multiple words within a specific category to describe an item). This can attract collectors directly from search engines and add to organic traffic.
User-Generated Content (UGC)
Why not encourage clients to leave detailed reviews and feedback? They can generate unique content that the search engines will index and add to the platform’s trust scores. The feedback might not only include the overall experience with a specific seller but the overall customer journey from the simplicity of search to speed of the payment processing.
Targeted Content Marketing
If this is a collectible marketplace, the targeted content marketing could include expert guides, price trackers, or collector forums to increase the website’s authority in the field.
Explore the promotion tactics you can apply before launching your marketplace.
Adding Advanced Features (AI Integration, Loyalty, Mobile Apps)
When the platform matures, it’s time to shift investment from core development to integrating new features that enhance functionality and enhance user experience.
AI Integration
Regardless of the advanced keyword-based search and filtering, AI empowers users to upload pictures of the items as a reference, while the AI algorithms can find similar listings on the platform. This can bypass the text-based search.
Loyalty Programs
Experiment with the badge systems, loyalty tiers, or embedded reward systems to promote repeat purchases. This can include lowering fees for loyal users.
Highly Intuitive Mobile Applications
If your website has a mobile version, then it must ensure a feature-rich experience with minimal disruption, lag, or slow performance. The essential tasks for marketplace mobile apps are browsing, status updates on bids/sales, and fast photo-based listing uploads.
Expanding to New Markets or Regions
Scalability requires investigating new markets once the domestic market is optimized.
Phased Rollout
Focusing on one or two adjacent regions brings consistency in trading after the platform tailors the marketing and tests its operational stability. The gradual market optimization promotes a balanced international expansion.
Targeted Localization
This is one of the most demanding scalability elements for platforms like eBay. It goes far beyond the contextual linguistic translation, but an in-depth adaptation to the market’s payment methods, regional tax requirements, and cultural preferences. This can even include partnerships with local shipping agencies, rather than relying on global delivery networks.
Cross-Border Integration
Why not implement eBay’s model for international logistics? You can integrate currency conversion and subsidized cross-border tracking for simplified international shipment processing.
Summary
If you’re wondering how to create a website like eBay, the key aspects you have to consider include eBay’s analysis (strengths & weaknesses), niche selection, and vendor/buyer attraction approaches. Underline a mobile-first strategy and focus on MVP first to validate ideas and the rationality of key features.
Ponder over the launch by starting at the targeted communities, as you can access the target audience directly. Finally, hire an outsourcing or in-house team to complete the development and make the platform scalable, efficient, and memorable.
