B2B marketplace development is building an online platform where many suppliers sell to business buyers, with features for bulk orders, negotiated prices and repeat purchasing. The platform owner runs the marketplace and usually earns a commission or subscription from each side.
You can build a B2B marketplace on ready-made marketplace software, extend an eCommerce platform such as Adobe Commerce, or build a custom platform. A first version (MVP) focuses on supplier listings, search, quotes, orders and payments; features such as ERP integration and tiered pricing follow.
Based on Intelivita's project pricing, a custom build costs from £12,000 for a simple first version and rises above £120,000 for a complex marketplace.
What Is a B2B Marketplace?
A B2B marketplace is an online platform where many suppliers list products or services and business buyers compare, order and pay in one place. The marketplace owner does not usually hold stock; it connects both sides and manages trust, payments and disputes.
Three differences set it apart from other online selling models:
- B2B marketplace vs B2B eCommerce site: a B2B eCommerce site sells one company's products to trade customers. A marketplace hosts many suppliers. A single-supplier trade shop follows the eCommerce web development process; a marketplace adds supplier accounts, commission and payouts.
- B2B vs B2C marketplace: B2B orders are larger and repeat often, prices are negotiated or tiered, and buyers often pay on invoice with credit terms. B2C marketplaces sell fixed-price items to consumers who pay by card.
- Marketplace vs directory: a directory lists suppliers but transactions happen elsewhere. A marketplace handles the order and payment.
Examples of B2B Marketplaces
- Alibaba.com: global marketplace connecting manufacturers and wholesale buyers.
- Amazon Business: Amazon's marketplace for business buyers, with business pricing and VAT invoices.
- Faire and Ankorstore: wholesale marketplaces connecting brands with independent retailers, both active in the UK.
Many B2B marketplaces are vertical: they serve one industry, such as construction materials, food service supplies or medical equipment, where buyers need specialist product data and verified suppliers.
What Are the Types of B2B Marketplace?
The three main types of B2B marketplace are buyer-oriented, supplier-oriented and intermediary. The type depends on who the platform mainly serves.
| Type | Who it serves | How it works | Typical use |
|---|---|---|---|
| Buyer-oriented (eProcurement) | A small number of large buyers | Buyers post requirements; suppliers bid; buyers choose the best terms | Procurement for large organisations |
| Supplier-oriented (eDistribution) | Suppliers reaching many buyers | Suppliers list products and prices; buyers browse and order | Wholesale catalogues |
| Intermediary | Both sides equally | Buyers and sellers sign up; the platform handles the transaction and takes a fee | Most independent marketplaces |
Marketplaces are also either vertical, serving one industry in depth, or horizontal, serving many industries with general products. Starting vertical is often easier, because suppliers and buyers in one industry are easier to find and serve.
Which Type of B2B Marketplace Should You Build?
Choose the type by the role your platform plays:
- If your platform gives suppliers a place to show products to many buyers, build a supplier-oriented marketplace.
- If it helps a few large buyers find suppliers for their requirements, build a buyer-oriented marketplace.
- If it is a neutral bridge where both sides transact through you, build an intermediary marketplace.
Once the type is clear, you can define the business model, research the market and brief the development team precisely.
How Do B2B Marketplaces Make Money?
B2B marketplaces make money mainly from commission on each order, with subscriptions, listing fees and paid services as extra or alternative income. Most combine two or more:
- Commission: a percentage of each order, taken when the buyer pays. It needs payments to run through the platform.
- Subscription: suppliers or buyers pay a monthly or yearly fee for access or for premium features.
- Listing fees: suppliers pay to list products or to appear higher in search.
- Paid services: financing, logistics, verification, data reports or advertising sold to either side.
The model affects the build. Commission needs split payments and seller payouts. Subscriptions need billing and plan management. Listing fees need ranking and promotion tools.
What Features Does a B2B Marketplace Need?
A B2B marketplace needs supplier and buyer accounts, product listings with search, request for quote, order management, payments and an admin dashboard. Build these first as a minimum viable product (MVP), then add features as suppliers and buyers ask for them.
MVP Features
| Feature | What it does |
|---|---|
| Registration and verification | Buyers and suppliers create accounts; the platform checks company details before approval |
| Company profiles | Company name, description, contact details, logo and certifications |
| Product listings and search | Suppliers list products with specifications and prices; buyers search and filter |
| Request for quote (RFQ) | Buyers request a price for a quantity or specification; suppliers respond with quotes |
| Messaging | Buyers and suppliers clarify details and negotiate inside the platform |
| Order management | Suppliers manage orders and invoices; buyers track order status |
| Payments | Card and bank payments through a gateway, with the platform's commission taken automatically |
| Admin dashboard | The platform owner approves suppliers, moderates listings, monitors orders and handles disputes |
B2B Features That Set It Apart
- Tiered and contract pricing: prices that fall with volume, or prices agreed for a specific buyer.
- Company accounts: several users per buyer company, with roles, spending limits and approval steps.
- Credit terms and invoicing: pay on invoice with 30- or 60-day terms, not only by card.
- Bulk and repeat ordering: order by spreadsheet upload, quick reorder and saved lists.
Features to Add After Launch
| Feature | What it does |
|---|---|
| Advanced search and filters | Filters by product attributes, certifications, location and ratings |
| Inventory management | Suppliers track stock levels and set reorder points |
| ERP and CRM integration | Orders, stock and customer data sync with suppliers' and buyers' business systems |
| Supplier and buyer ratings | Ratings for product quality, delivery time and service |
| Multi-language and multi-currency | Local languages, currencies and tax settings for international trade |
| Analytics | Reports on sales, categories and trends for the owner and suppliers |
The marketplace type decides which features matter most. A buyer-oriented platform needs strong RFQ and bidding tools first; a supplier-oriented one needs catalogue and search tools first.
Should You Use Marketplace Software or Build a Custom B2B Marketplace?
Use ready-made marketplace software to test an idea quickly and cheaply. Build a custom B2B marketplace when your workflows, pricing rules or integrations do not fit what the software offers. A common path is to start on software and move to a custom build once demand is proven.
| Option | Examples | Best for | Main limit |
|---|---|---|---|
| Ready-made marketplace software | Sharetribe, CS-Cart Multi-Vendor, Yo!Kart B2B | Testing an idea; standard listings, orders and commission | Limited B2B features such as RFQ, credit terms and complex pricing |
| eCommerce platform with marketplace extensions | Adobe Commerce with a multi-vendor extension; Shopify Plus B2B with marketplace apps | Businesses already on that platform | Extensions add cost and can limit how far the platform can be changed |
| Custom build | A web platform built on a framework such as Laravel, Node.js or React | Unique workflows, ERP integration, large catalogues, long-term ownership | Highest upfront cost and longest build |
A custom build gives you full ownership of the code and data, and no software subscription; payment gateway fees still apply. Ready-made software costs less upfront but charges monthly fees and limits how far you can change the buying process.
How Do You Build a B2B Marketplace?
To build a B2B marketplace, research the market, define the scope, design the buyer and supplier journeys, build an MVP, connect payments and business systems, test, then launch with a first group of suppliers.
Step 1: Research the Market
Research shows whether the idea is viable before you spend on development. Customer research covers both sides: what buyers struggle to source and what suppliers need to reach new buyers. Competitor research identifies existing marketplaces, distributors and procurement tools in your industry, their strengths and their gaps.
Step 2: Define the Scope and Milestones
The project scope sets the deliverables, features, timeline and budget. Split the work into milestones, such as accounts, catalogue, RFQ and payments, so progress is visible. A short timeline gets you to market sooner, but too short a timeline lowers quality.
Step 3: Design the Buyer and Supplier Journeys
UI/UX design turns the scope into wireframes and a clickable prototype. Design separate journeys for buyers, suppliers and the admin team. The prototype lets you test the journeys with real users and helps when raising investment.
Step 4: Build the MVP
Developers turn the designs into a working platform: the front end that users see and the back end that handles accounts, listings, quotes, orders and the admin dashboard. A project manager tracks each milestone, such as login, catalogue and API development.
Step 5: Connect Payments and Business Systems
The platform connects to a payment provider that can split payments and pay suppliers, plus accounting, logistics and, where needed, ERP systems. Integrations take longer in B2B than B2C, because each supplier and buyer may use different systems.
Step 6: Test the Platform
Test every journey: supplier sign-up and approval, listing, RFQ, ordering, payment, payout, refund and dispute. Test security too, including access controls between companies, because one company must never see another's prices or orders.
Step 7: Launch With a First Group of Suppliers
Launch with suppliers already on board, so buyers find products on day one. Collect feedback, fix problems quickly and add features in short release cycles. Maintenance continues after launch: security updates, bug fixes and new features as the marketplace grows.
How Do Payments Work in a B2B Marketplace?
In a B2B marketplace, the buyer pays the platform, the payment provider splits the money, the platform keeps its commission, and the supplier receives the rest as a payout. This needs a payment provider built for marketplaces, such as Stripe Connect, PayPal for Marketplaces or Adyen for Platforms.
A marketplace payment set-up covers five jobs:
- Supplier onboarding: the payment provider checks each supplier's identity and bank details before they can be paid.
- Split payments: one buyer order can include several suppliers; the payment is divided between them automatically.
- Commission: the platform's fee is taken before each payout.
- Payouts: suppliers receive funds on a schedule, often after delivery is confirmed, which protects buyers.
- Invoicing and credit terms: many business buyers pay by bank transfer on 30- or 60-day terms. Trade credit providers can pay suppliers upfront and collect from the buyer later.
Not every gateway supports split payments, so check this before choosing one. The comparison of UK online payment gateways covers fees and features for the main providers.
How Much Does It Cost to Build a B2B Marketplace?
A custom B2B marketplace costs from £12,000 for a simple first version and rises above £120,000 for a complex platform, based on Intelivita's project pricing. An MVP usually takes 4–6 months to build, and a full-featured marketplace 6–12 months.
Intelivita prices marketplace projects in stages:
| Stage | What it covers | Intelivita price |
|---|---|---|
| Initial consultation | Scoping, requirements, quotation, fixed cost and timeline | £0 |
| UX/UI design and clickable prototype | Buyer, supplier and admin journeys, wireframes, Figma design, prototype | £4,000–£20,000 |
| Development | Web platform, back end and APIs, admin dashboard, payments and integrations | £8,000–£100,000+ |
| Post-launch support | Maintenance, security updates, platform upgrades, improvements | £400–£2,000 a month |
Five things move a marketplace up the range: B2B features such as RFQ and contract pricing, the number of integrations (ERP, accounting, logistics), split payments and credit terms, a mobile app alongside the web platform, and the number of languages and currencies. Ready-made marketplace software costs less to start but adds monthly fees.
The factors behind app development costs in the UK apply here too, with extra work for supplier onboarding, payouts and multi-company permissions.
What UK Rules Apply to a B2B Marketplace?
A UK-based B2B marketplace must report seller income to HMRC, handle VAT correctly on marketplace sales, protect personal data under UK GDPR, and publish clear terms for buyers and suppliers.
- HMRC reporting rules for digital platforms: since 1 January 2024, UK platforms that connect sellers with buyers must collect seller details and report their income to HMRC each year, by 31 January for the previous calendar year. Small occasional sellers below set thresholds are excluded†.
- VAT on marketplace sales: an online marketplace can be liable for VAT on goods sold by overseas sellers, for example goods already in the UK or consignments of £135 or less. When the business buyer gives a valid UK VAT number, the marketplace does not charge VAT on those low-value imports; the buyer accounts for it instead†.
- UK GDPR and the Data Protection Act 2018: the platform holds personal data about suppliers' and buyers' staff, so it needs a privacy notice, secure storage and clear data-sharing rules between companies.
- Platform terms: terms of use for buyers and suppliers should cover listing rules, fees, payment timing, disputes and liability.
- Payments: a regulated payment provider holds and moves funds for you. Handling buyers' money yourself can require authorisation from the Financial Conduct Authority.
This is general information, not legal or tax advice. Confirm your obligations with HMRC or a qualified adviser.
What Are the Main Challenges of B2B Marketplace Development?
The main challenges are attracting the first suppliers and buyers, mapping complex B2B workflows, integrating different business systems securely, verifying suppliers, and scaling under heavy use.
- The cold-start problem: buyers will not come without suppliers, and suppliers will not join without buyers. A common solution is signing up a core group of suppliers before launch and focusing on one industry or region first.
- Complex business processes: B2B orders involve quotes, approvals, contracts and credit terms. Each workflow must be mapped with suppliers and buyers before it is built.
- Data integration and security: the platform connects to systems owned by different companies. Strong encryption, access controls and regularly updated authentication keep each company's prices and orders private.
- Supplier onboarding and verification: checking company details, certifications and compliance takes time, but it is what makes buyers trust the platform.
- Scalability and performance: the platform must handle large catalogues, bulk orders and traffic peaks without slowing down or failing.
FAQs
What does B2B marketplace mean?
A B2B (business-to-business) marketplace is a website or app where many suppliers sell products or services to other businesses. Buyers compare suppliers, request quotes, order and pay in one place, and the platform owner earns a fee.
What are some examples of B2B marketplaces?
Alibaba.com, Amazon Business, Faire and Ankorstore are well-known B2B marketplaces. Many others serve a single industry, such as construction supplies or catering equipment.
Are online marketplaces profitable?
A marketplace becomes profitable when commission and fees from enough repeat orders cover development, marketing and running costs. Profit depends on order volume and repeat purchasing more than on the number of sign-ups, which is why B2B marketplaces with regular reorders can earn steadily once both sides are active.
How long does it take to build a B2B marketplace?
An MVP usually takes 4–6 months, and a full-featured custom marketplace 6–12 months. Ready-made marketplace software can launch in weeks, with fewer B2B features.
Does a B2B marketplace need a mobile app?
Not at launch. Many B2B buyers order from desktops at work, so a responsive web platform comes first. Add an app later if suppliers or buyers need mobile ordering, stock updates or notifications.
What is the difference between a B2B marketplace and a B2B eCommerce website?
A B2B eCommerce website sells one company's products to trade customers. A B2B marketplace hosts many suppliers and needs extra features: supplier accounts, commission, split payments and payouts.
