What Is a B2B Marketplace? How It Works for Suppliers and Buyers

In short. A B2B marketplace is an online platform where businesses find and contact, or buy directly from, other businesses. There are two broad types: transactional marketplaces such as Alibaba.com and Amazon Business, where orders and payments run through the platform, and directory or lead-generation platforms such as Europages, wlw, Kompass and national directories like Romanian Supplier, where buyers discover suppliers and contact them directly. For a supplier, a marketplace delivers visibility and inquiries, not contracts.

What is a B2B marketplace?

A B2B (business-to-business) marketplace is a website or app that brings many sellers and many business buyers together in one searchable place. Suppliers publish company profiles, products or services; buyers search, compare and send inquiries or orders. The platform earns money from subscriptions, commissions, advertising or a mix of these.

The definition sounds simple, but the term covers very different business models. When a Romanian furniture maker hears "marketplace", they may picture Amazon: a shopping cart, a checkout, a logistics network. When a German procurement manager hears it, they may picture a supplier database where they shortlist five manufacturers and then email them. Both are B2B marketplaces. They work differently, they attract different buyers and they reward different supplier behaviour.

Three elements are common to almost every B2B marketplace:

1. Supply side: companies that list what they make or offer, usually with a structured profile (industry, products, certifications, markets served, contact details).
2. Demand side: professional buyers, from procurement teams in large groups to small retailers and distributors, who search for sources of supply.
3. Matching mechanism: categories, search filters, requests for quotation (RFQs), recommendations or direct messaging that connect the two sides.

What differs is what happens after the match: does the deal close on the platform, or does the platform hand the conversation over to the two companies?

What types of B2B marketplaces exist?

There are two main families. Transactional marketplaces process the order and the payment inside the platform. Directory and lead-generation platforms help buyers discover and contact suppliers, and the negotiation, contract and payment happen outside. Many platforms mix elements of both, so look at how a deal is actually completed.

Transactional marketplaces

On a transactional marketplace the buyer can place an order, pay and often track delivery without leaving the platform. Two well-known examples:

• Alibaba.com. A global wholesale marketplace where buyers can search products, post RFQs and order. Alibaba describes its Trade Assurance programme as built-in order protection: buyers pay through the platform, orders follow documented terms and disputes go through a structured resolution process.
• Amazon Business. Amazon's procurement marketplace for organisations. In August 2025 Amazon said Amazon Business served more than 8 million organisations in 11 countries, with more than $35 billion in annualised gross sales (PYMNTS, 20 August 2025).

These platforms suit standardised products with clear prices, stock and shipping terms: office supplies, packaging, components, consumables. For a supplier, they require operational readiness (price lists, stock management, fulfilment, returns) and usually involve commissions or fees per sale.

Directory and lead-generation platforms

A directory platform focuses on discovery. The buyer finds a supplier, reads the profile and makes contact. The platform does not handle the order or the money. Examples:

• Europages. A pan-European B2B platform operated by Visable. Visable states that Europages has about 2.2 million registered companies and around 1 million buyers per month. Buyers use it free of charge, suppliers can create a free profile, and paid options increase visibility in search results (Visable, B2B platforms).
• wlw (formerly "Wer liefert was"). Also operated by Visable, focused on Germany, Austria and Switzerland. Visable describes a free standard profile and paid professional options, with profiles showing company size, delivery region, certifications and an overview of products or services (Visable magazine).
• Kompass. A long-established international business directory that also sells company lists; on its website Kompass refers to more than 60 million companies across 70 countries (Kompass).
• National and niche directories. Platforms that focus on one country's suppliers or one industry. Romanian Supplier is one of them: a directory of Romanian manufacturers and suppliers built for international buyers.

These platforms suit custom manufacturing, contract production, industrial components, private label, food products with specific requirements and services: anything where the price depends on specifications, volumes and negotiation.

Side-by-side comparison

Neither model is "better". They answer different needs. Many Romanian manufacturers who make products to order will find directory platforms a more natural fit. Producers of packaged, standard goods may use both. For a wider overview of European options, see our guide to Alibaba alternatives in Europe.

How do B2B buyers actually search for suppliers?

Professional buyers combine several routes: keyword search on Google and on platforms, browsing industry categories, posting RFQs and, more and more, asking AI assistants for shortlists. Most of the early research happens before any contact with a salesperson, so a supplier's online information has to answer questions on its own.

Gartner's March 2026 survey of 646 B2B buyers found that 67% prefer a rep-free buying experience and 45% used AI during a recent purchase (Gartner, 9 March 2026). In practice this means a buyer may have read your profile, compared you with three competitors and formed an opinion before you know they exist.

The main search patterns are:

1. Category browsing

A buyer who knows the industry but not the suppliers starts from a category: "metal fabrication", "wooden furniture", "organic honey". Category pages work like a shelf. Being correctly classified, with the right industry and subcategory, determines whether you are on that shelf at all.

2. Keyword search

Buyers type specific terms, such as "CNC machining Romania", "private label cosmetics manufacturer EU" or "oak flooring supplier Eastern Europe", into Google or into the platform's own search box. Profiles that use the same words buyers use (product names, materials, processes, certifications) are found more often than profiles with generic descriptions like "quality products at good prices".

3. Requests for quotation (RFQs)

On some platforms, buyers post a requirement (product, specification, quantity, delivery terms) and suppliers respond with quotes. On Alibaba.com, for example, buyers fill in a "Post Request for Quotation" form and then compare the responses they receive. RFQs reverse the usual flow: the buyer describes the need and suppliers compete to answer it. Response speed and completeness matter a lot here.

4. Direct inquiry from a profile

On directory platforms the most common action is a message sent from the supplier's profile: a question about minimum order quantity, a request for a catalogue or a price list, or an invitation to quote. That message is the real "conversion" of a directory listing.

5. AI assistants and answer engines

Buyers increasingly ask ChatGPT, Perplexity, Gemini or Copilot questions like "Which Romanian manufacturers produce aluminium profiles?" These systems build their answers from publicly accessible, indexed web pages. A supplier with no clear public information (no website, or a thin website and no directory profiles) gives these tools little to work with.

The practical conclusion: buyers search in several places at once, and a supplier needs consistent, specific information across its own website and the platforms it uses.

What does a supplier get from a B2B marketplace?

A supplier gets three things from a well-chosen B2B marketplace: visibility in front of buyers who are already searching, a direct channel for inquiries, and an extra indexed web page that search engines and AI assistants can find. The value depends on how complete the profile is and how quickly the company answers.

Visibility where buyers already look

A marketplace gathers buyer demand in one place. A small manufacturer in Suceava or Bihor cannot easily rank on its own for "furniture manufacturer Romania" against larger players and aggregator sites. A profile inside a category that buyers browse puts the company in the comparison set.

Inquiries through a direct channel

Directory platforms turn visibility into messages: catalogue requests, quote requests, questions about capacity or certifications. Each inquiry is a sales lead that did not require cold outreach.

An indexed profile that supports SEO and AI visibility

A public company profile on an established platform is a separate web page about your business. When search engines crawl and index it, it can appear in results for your company name, your products or your region, and it can be used as a source by AI assistants. It also gives a buyer who is checking you a second, independent place to confirm your details.

Credibility signals

A structured profile (address, year founded, industry, products, markets, certifications) helps buyers do a first check quickly. On Romanian Supplier, information declared by companies, such as certifications, export markets or number of employees, is clearly marked as declared. How this works is explained in how Romanian Supplier reviews company data.

What does a B2B marketplace not give you automatically?

A marketplace does not guarantee orders, rankings or qualified leads. It does not replace a quote, a sample, a factory visit or a contract, and it does not do the follow-up for you. A listing is a starting point; results depend on profile quality, responsiveness and fit with what buyers are searching for.

It is worth being direct about the limits, because unrealistic expectations are the main reason suppliers abandon platforms after a few months:

• No guaranteed ranking or indexing. Google states that it does not guarantee it will crawl, index or serve a page, even if the page follows its Search Essentials (Google Search Central). The same applies to marketplace profiles: thin or duplicated pages are less likely to be shown.
• No guaranteed lead volume. Demand differs a lot by industry. A supplier of a widely sourced category will see more searches than a highly specialised one.
• No automatic lead quality. Some inquiries will be vague, from very small buyers, or simply price comparisons. Qualifying them is the supplier's job.
• No closing. On a directory platform the platform hands over the contact. Quoting, negotiation, samples, payment terms and logistics are between buyer and supplier.
• No substitute for your own website. A profile complements a website; it does not replace it. Buyers who are seriously interested will usually look for both.
• No factory audit. Directory platforms generally do not inspect production sites. Buyers still run their own due diligence before signing a contract.

How does Romanian Supplier work?

Romanian Supplier is a B2B directory that connects Romanian manufacturers and suppliers with international buyers. As of September 2026 it lists 11,113 Romanian companies classified into 18 industries. Buyers browse and search for free and contact companies directly; suppliers present their company, products, brands, services and solutions on dedicated pages.

The platform is operated by SC FABRICATINRO SRL in Iași, the team behind Fabricat în RO, which has been promoting Romanian producers since 2014. Romanian Supplier applies the same idea to export: making Romanian suppliers easy to find for buyers abroad.

What a supplier can publish

Each page is a separate, indexable URL. Buyers can find the content through the platform's own navigation, such as the company directory and the product catalogue, through Google, or through AI assistants that cite web sources.

How profiles get published

Every company profile is reviewed by the Romanian Supplier team before publication. The review checks that the profile is coherent and belongs in the right industry. It is not a factory audit: data declared by companies is marked as declared, and buyers should run their own checks before ordering.

How buyers contact suppliers

Buyers send messages to companies directly from their profiles or product pages: a request for a quote, a catalogue, samples or more information. The supplier receives the inquiry and replies. Negotiation, contracts and payments then happen directly between the two companies; Romanian Supplier does not intermediate transactions or take a commission on sales.

Plans

A free profile is available to every company. Paid plans (Basic, Professional and Enterprise) add more products, images and video, visible website and phone number, a featured position in industry hubs, promotion towards a specific foreign market and, at Enterprise level, multilingual profiles. Current details and prices are on the pricing page. If you are deciding whether an upgrade is worth it, our guide to the ROI of a premium supplier listing shows how to calculate it.

Illustrative example: one supplier, two platform models

The following scenario is illustrative. The company is fictional.

"Carpathia Metal Works" is a 40-person fabrication shop near Brașov making welded steel frames and laser-cut parts to customer drawings. The owner wants to find customers in Germany and Austria and has a modest marketing budget.

First attempt: a transactional marketplace. The team creates a storefront and tries to list "products". The problem appears immediately: everything they make is custom. There is no fixed price, no stock and no standard shipping weight. They upload a few sample parts with "price on request". Over three months they get a handful of messages, mostly from buyers looking for cheap standard brackets in small quantities.

Second attempt: directory platforms. The team rebuilds its presence around what buyers actually search for. On two directory platforms, including a Romanian one, the profile now lists:

• processes (laser cutting up to a stated sheet thickness, MIG/TIG welding, powder coating);
• materials (structural steel, stainless steel, aluminium);
• declared certifications (ISO 9001, EN 1090);
• typical batch sizes and lead times;
• export experience (already delivers to two EU countries);
• a services page for "laser cutting" and another for "welded steel frames".

Within the first months the inquiries are fewer than they hoped, but more relevant: a German machine builder asking for a quote on 200 frames, an Austrian distributor requesting a capability presentation. The owner answers within one working day, sends a short PDF capability deck and offers a video call.

The lesson is not that one model is good and the other bad. A custom manufacturer needed a discovery platform where buyers describe a need, not a shopping cart. A supplier of standard, priced goods might have had the opposite experience.

How do I choose the right B2B marketplace for my company?

Choose a marketplace by fit, not by size alone. Check five things: who the buyers are, whether your industry is well represented, how the platform charges, what kind of leads it generates and which languages and markets it covers. Then test it for a defined period with clear metrics.

Selection checklist

1. Audience

• [ ] Which countries do the platform's buyers come from? Does it publish any figures, and with what source and date?
• [ ] Are buyers professional (procurement, distributors, retailers) or mostly consumers?
• [ ] Is the platform's audience looking for suppliers from a country or region like yours?

2. Industry fit

• [ ] Does it have a clear category for what you make?
• [ ] Are there competitors already listed (a sign of buyer demand), and are there so many that you would be invisible?
• [ ] Can you publish product, service and capability pages, or only a short company card?

3. Cost model

• [ ] Free profile, subscription, commission per sale, pay-per-lead or advertising?
• [ ] What is included at each level, and is the contract monthly or annual?
• [ ] Are there cancellation terms or minimum periods?

4. Lead quality

• [ ] Do inquiries come with company name, country and a description of the need?
• [ ] Is there any filtering of spam or obviously unqualified requests?
• [ ] Can you contact the buyer directly, or only through the platform?

5. Language and market coverage

• [ ] Is the platform available in the languages of your target buyers?
• [ ] Can your profile be presented in more than one language?
• [ ] Does the platform help you target a specific export market?

6. Data and control

• [ ] Can you see statistics such as profile views and inquiries?
• [ ] Can you edit your profile yourself at any time?
• [ ] Is your profile publicly indexable, or hidden behind a login?

A practical rule: start with one or two platforms that fit your industry and target markets, complete the profiles properly, and only add more once you can measure what the first ones deliver.

How do I measure results from a B2B marketplace?

Measure a marketplace like any sales channel: track profile views, inquiries, qualified leads, quotes sent, deals won and revenue, and compare that with the cost and time invested. Give each platform at least six months, because B2B sales cycles are long and early numbers are small.

A simple measurement funnel

Practical tips

• Tag the source of every lead. Ask "How did you find us?" and record the answer. Use UTM parameters on links to your website where the platform allows it.
• Track response time. Many lost deals are lost in the first 48 hours. Measure how long your team takes to answer an inquiry.
• Calculate cost per qualified lead. Divide what you spend on the platform (subscription plus staff time) by the number of qualified leads, not by all inquiries.
• Account for long cycles. In industrial sourcing, the time from first inquiry to first order can be many months. Record early pipeline value, not only closed deals.
• Watch indirect effects. A profile may bring buyers who later contact you through your website or by phone. Ask, and record it.
• Review quarterly. Update the profile with new products, photos and certifications and check whether the numbers change.

How do I make a marketplace profile work harder?

A profile works when it answers a buyer's first questions without a phone call: what you make, from which materials and processes, in what volumes, with which certifications, for which markets, and how to reach you. Specific, complete and current profiles receive more relevant inquiries than generic ones.

The essentials:

1. Write for the buyer's search terms. Use product names, materials, processes and standards, not slogans.
2. Show real production. Photos of the workshop, machines, finished products and packaging. Add a short video if the plan allows.
3. State capacities and conditions. Minimum order quantities, lead times, monthly capacity, Incoterms you work with.
4. List certifications precisely. Standard, scope and issuing body, and keep the documents ready to send.
5. Separate products, services and brands. Each on its own page, so each can be found on its own.
6. Answer fast. Treat a marketplace inquiry like a phone call from a prospect.
7. Keep it current. An outdated profile is a negative signal for both buyers and search engines.

Our step-by-step guide on building a supplier profile buyers trust covers each point in detail.

Why does this matter specifically for Romanian suppliers?

Romanian companies sell online less than their EU peers, so many international buyers have little digital information about Romanian suppliers. A complete presence on the right B2B platforms is a relatively low-cost way to close that information gap and to appear when buyers search for European alternatives.

Eurostat data for reference year 2022 shows that 22.9% of EU enterprises made e-commerce sales, while Romania had the lowest share in the EU at 12.9% (Eurostat, E-commerce statistics). That gap is a problem and an opportunity. It means fewer Romanian suppliers are visible online, but those who invest in a clear, specific digital presence face less competition from domestic peers when a foreign buyer searches for "manufacturer Romania".

For buyers, it explains why sourcing from Romania can feel harder than it should: good manufacturers exist, but many are not easy to find. National directories that focus on one country's suppliers try to close exactly that gap.

Frequently asked questions

What is the difference between a B2B marketplace and a B2B directory?

A B2B marketplace usually lets buyers order and pay on the platform. A B2B directory helps buyers find suppliers and contact them; the deal happens outside the platform. In everyday use, "B2B marketplace" covers both, and many platforms combine elements of each.

Is Romanian Supplier a transactional marketplace?

No. Romanian Supplier is a directory and lead-generation platform. Buyers find Romanian companies, view their profiles, products, brands, services and solutions, and contact them directly. Orders, contracts and payments are handled between the buyer and the supplier, with no commission taken by the platform.

Do I need a B2B marketplace if I already have a website?

A website and a marketplace profile do different jobs. Your website presents your company in full; a marketplace places you where buyers compare suppliers and adds another indexed page about your business. Most exporting companies benefit from having both, with consistent information.

How much does it cost to list a company on a B2B marketplace?

It depends on the model. Directories often offer a free basic profile and paid plans for more visibility; transactional marketplaces typically charge commissions or fees per sale, sometimes with a subscription. On Romanian Supplier, a free profile is available and paid plans are listed on the pricing page.

How long does it take to see results?

Expect several months. Profiles need time to be indexed, and B2B buying cycles are long. Measure profile views and inquiries in the first months and qualified leads and deals over six to twelve months.

Does a marketplace verify suppliers?

It depends on the platform, and the word "verified" can mean very different things. Romanian Supplier reviews every profile before publication but does not audit factories; information declared by companies is marked as declared. Buyers should always do their own due diligence before signing a contract.

Can buyers use Romanian Supplier for free?

Yes. Buyers can search companies, products and services and contact suppliers without paying.

Next step

If you are a Romanian manufacturer or supplier, the fastest way to test a B2B directory is to publish a complete profile and measure what it brings over the next six months. List your company on Romanian Supplier for free, then compare the plans on the pricing page once you know which features you need.

If you are a buyer looking for suppliers in Romania, start with the company directory, filter by industry and send your first inquiry directly to the manufacturers that match your requirements.
