  • There are multiple types of B2B portals, including supplier, customer, partner, and self-service portals, each serving different business needs.
    
  • Development costs vary by stage, with expenses covering planning, design, development, integration, testing, and ongoing maintenance.
    
  • B2B portals can be integrated with existing business tools such as CRM, ERP, inventory management, and marketing automation.

So, what is a B2B portal?

A B2B (business-to-business) portal is an online platform that helps businesses communicate and collaborate. By default, these websites are trickier than B2C portals, which are made for individual consumers.

Unlike your average online store, B2B software cannot focus on just buying and selling. On this platform, users should be able to comfortably manage supply chains, inventory, customer interactions, and many other things depending on what the main goal of the portal is.

Key aspects of B2B portals

The features you would expect from well-built B2B portals include (but aren’t limited to):

• • Centralized communication. Businesses should be able to communicate seamlessly with partners and suppliers.
  • Automated transactions. Naturally, this is important if your B2B portal is all about orders, invoicing, and payment processing.
  • All-in-one solutions & self-service options. Users should easily access order management, support, and account settings.
  • Tailored to one’s needs. Usually, B2B portals can be customized depending on your unique business objectives.

What are the most common types of B2B portals?

Let’s dive deeper into that “tailored to one’s needs” part. Basically, it means that different goals require different B2B portals. Some of them resemble B2C marketplaces (just more significant and more complex), and others lean more towards planners, classifieds, or even task trackers.

Here are the most common ones.

1. Supplier portals

The main purpose of these portals is to connect suppliers and buyers. It serves as a centralized hub where companies can manage acquisitions, track orders, exchange documents, and collaborate with vendors.

⭐Our experience   A Swiss entrepreneur wanted to make Look4pro, a B2B platform that’ll let European SMEs post unique requests for services, goods, or investments. Initially considering a P2P platform for rare item searches, they pivoted to B2B. We helped with market research, came up with a design concept that got praised even by Swiss startups, added multilingual content, and integrated the Stripe payment system. As a result, we created a unique platform with a clean and user-friendly design that left the client happy and inspired for new milestones. Look4Pro is a platform where entrepreneurs can find suppliers, contractors, and potential business partners, even in niche areas

2. E-commerce portals

Even people who aren’t in business may know how these look. E-commerce portals enable online sales between businesses, ideally providing secure payment processing and catalog and inventory management.

One of the most obvious examples would be Alibaba.com, the world’s biggest B2B e-commerce brand. Among the things it does best are catalog optimization, multiple language options (from English and Chinese to Spanish and Russian), and customizable business solutions (you can get in touch with suppliers and forge your own deal).

Another well-known example of a B2B e-commerce web portal is Amazon. It’s not too different from its B2C fellow portal when it comes to design and appeal. However, it seamlessly shifts focus to what’s important for various industries.

3. Customer portals

Business doesn’t just sell. It also has to stay in touch with suppliers and customers. That’s exactly the main function of B2B customer portals — a secure, self-service platform that empowers businesses to manage tasks and access their communication history, all in one convenient place.

That’s where web customer portals like Zendesk come into play — by giving users control over their interactions, businesses can boost satisfaction and build stronger relationships. When you have an order to manage, you don’t just want to know how much it costs and how to buy it — you also want to stay updated on its status and receive support when needed.

4. Partner portals

Businesses can be clients, but they can also be partners, either trying to look for new contacts or fostering the already existing ones. That’s what partner B2B portals are for: they help establish and enhance business relationships between distributors, resellers, and affiliates.

One of the biggest web portals that serve this purpose is Impact while not selling products or managing invoices and orders. It offers “direct access to global brands,” from affiliate and influencer marketing to SaaS and analytics services.

⭐Our experience   A client approached us with an idea to create a database with 60 million records that would help companies find leads — a true game changer for any B2B sales department. The challenge wasn’t just to turn this many records into a user-friendly lead generator but also to integrate it with lots of different CRMs and regularly update and maintain them — something we continue to do today. An online lead generation software has to have the capacity to integrate as many CRMs as possible so that any company can instantly incorporate them into their workflow We also implemented a powerful search engine, email verification, and the BrainTree payment system. In the end, we managed to create a service that outplayed big competitors like ZoomInfo, Clearbit, and D&B Hoovers.

5. Enterprise Resource Planning (ERP) Portals

These B2B portals are basically platforms that integrate with existing systems to manage operations. This is where businesses can connect with real-time data on operations, finances, inventory, and more.

If that sounds too complex, you can think of ERP portals as a smart home control system. In a smart home, you need to control many systems at once: lighting, heating, security, appliances, etc. In business, an ERP portal connects departments from finance to inventory, and makes sure they are all accessible from one place.

Solutions like SAP and Oracle ERP portals are a good example of such platforms.

6. Custom Web Portals

Of course, the variety of B2B portals doesn’t end with that. Any unique solution that can be integrated with what’s already done for specific business needs can be defined as a custom web portal.

Sometimes, you need your B2B portal to be a bit of a supplier platform with a sprinkle of customer portals. Or you want your ERP to include some functions of a partner database. It really depends on your business infrastructure and goals, and sometimes, generic examples simply don’t match them.

⭐Our experience   We developed a smart web application Appt that helps new businesses automate lead generation and enhance their online presence. It doesn’t really fall into any other B2B portal type, but it sure does serve a lot of purposes, from order management to reporting tools. We made sure the navigation is intuitive and all necessary features are a click away. This way, Appt provides an opportunity to describe your business, raise funds, make appointments, and receive feedback Analytics is vital for any business, which is why we provided a handy dashboard for that, too. It’s a smart tool used to track KPIs and important business metrics

How will B2B portal development actually help your business?

An efficient B2B portal can be a lifesaver, especially if your business has a lot of processes to automate and centralize. Let’s look into the key benefits of having a B2B portal:

• • Improved business efficiency. Less manual work and more processes made automatic.
  • Enhanced customer satisfaction: self-service portals help resolve any issues more quickly.
  • Better inventory management: a B2B portal helps you track stock levels, reducing delays and shortages.
  • Secure transactions: robust security measures for payments and data exchange that you have full control of.
  • Improved business relationships: collaboration between business partners and suppliers becomes way easier.

Keeping up with the trends: according to IoT Analytics’ B2B Technology Marketplaces Market Report, just B2B software marketplaces are expected to make up 10% of all global enterprise software purchases by 2030.

We don’t just say that B2B portals are trendy out of nowhere. Oren Greenberg’s statistics, among other things, confirm that the B2B e-commerce market is projected to grow to $47,772.6 billion by 2030, with an estimated annual growth rate of 11.8% from 2021 to 2030.

Checklist of essential features of a perfect B2B portal

Let’s make it clear — you don’t have to adjust your B2B portal to any templates. However, having a checklist of features that will most likely benefit your platform may still help.

• • User Management. This one includes things from creating and managing the account to controlling the different levels of access for various users. Role-based permissions help maintain data privacy and streamline operations.
  • Order Management. Automate order processing, track shipments in real time, and reduce errors by integrating with inventory and fulfillment systems. In many cases, this is one of the most important features of a B2B portal.
  • Payment Integration. Unless you’re doing charity or feeling generous, your B2B portal should offer seamless, reliable, and secure payment processing. Remember about different payment options: from bank cards to digital wallets.
  • Inventory Management. Monitor stock levels, receive low-stock alerts, and optimize supply chain operations. Real-time inventory tracking prevents overstocking or stockouts, so everyone receives their order on time, and the “not in stock” label isn’t an unpleasant surprise to anybody.
  • Customer Relationship Management (CRM). A built-in CRM helps store and manage customer data, track interactions, manage ticketing systems, and automate follow-ups.
  • Reporting Tools. Analytics is an integral part of any business. The more accessible and user-friendly your reporting tools are, the easier it is to generate detailed reports on sales, orders, payments, and customer behavior.

6 main steps in B2B portal development

At Purrweb, we prefer to map out our development process. Keep in mind that it may differ in other agencies, but if you decide to develop your B2B portal with us, here are the steps we would take.

Step 1. Requirement analysis

This is arguably the most important step of the entire process, with its main goal being to identify business needs and define business goals. In project management, this step is also known as the project discovery phase. Here, we analyze the market, the competitors, the audience, industry standards, and many other things.

At Purrweb, this step can take up to 8 weeks, and the cost starts at $3,000. This may seem like a long time and a lot of money, but this is the stage where the most important research is done. It is also the best time to discover hidden problems and not-so-obvious pitfalls — in the end, fixing them will save you a lot more money.

⭐Our experience   We sure know how product discovery helps cut costs. When we developed the Journey Verse travel planner, we managed to save our client almost $40,000 and make a viable and effective MVP. Our client’s first idea was to create a social network for travelers, but the product discovery phase helped us come up with a much more useful product: an app that would help plan trips. Thanks to interviews and market research, we identified the audience and their main pain: planning takes a lot of effort and may become stressful if things go sideways That’s why it was better to turn Journey Verse into a travel planner. Because it saved time and energy, people were ready to pay for it. People prefer free solutions but are ready to pay for the product if they see its value

Before writing a single line of a B2B portal code, here are the goals we would set:

• • Identifying the key problems the portal should solve (e.g., order management, supplier collaboration, self-service options).
  • Defining the target audience and their needs (suppliers, distributors, business clients, etc.).
  • Conducting market research and competitor analysis to ensure the portal provides unique value.
  • Outlining essential and advanced features, integrations, and scalability needs.

Step 2. UI/UX design

Then begins the journey to create an intuitive user engagement experience. Even with complex features, a good B2B portal must be easy to navigate. Here’s what needs to be done to make sure that happens:

1. Wireframing and Prototyping. It’s about designing the structure and layout before development.
2. User Flow Optimization. This is where it’s important to ensure smooth navigation for different roles (e.g., admin, suppliers, buyers).
3. Accessibility & Responsiveness. Making the portal user-friendly across mobile devices, tablets, and desktops is a must in 2025.
4. Branding & Personalization. Last but not least, it’s about customizing the interface to align with company identity and user expectations.

Step 3. Development

Now, we’re down to business! This is the most technical (and usually the longest) phase, where the actual web portal development begins. Key aspects include:

Choosing the tech stack. It’s about selecting web development frameworks that will work best for your custom platform.

Coding the platform. Here, we start implementing features like product catalogs, self-service portals, secure payment gateways, and real-time dashboards.

Implementing security measures. Never forget about robust security measures like SSL encryption, multifactor authentication (MFA), and access controls to protect business data.

Database & infrastructure setup. Finishing up with configuring databases (SQL, NoSQL) and cloud solutions for scalability and performance.

We also divide the development process into 2-week sprints. After each of them is completed, we provide all the progress reports.

Step 4. Integration

You don’t always need to integrate your B2B portal with enterprise systems, but when you do, it’ll happen at this stage. Your case may be different, but here are the examples of ways to integrate your portal with other systems that are already in place:

Type of integration	Examples of systems/services	What for
ERP integration	SAP, Oracle, or Microsoft Dynamics	For inventory management and financial reporting
CRM integration	Salesforce, HubSpot, or Zoho CRM	For lead tracking and customer relationship management
Payment and billing systems	Stripe, PayPal, Braintree	For payment processing and automated invoicing
Supply Chain & Inventory Management	NetSuite, TradeGecko, ShipStation	For real-time stock updates and logistics tracking

Step 5. Testing

In fact, we do our tests on every step to make sure things go smoothly and include the results in our progress reports. This way, it’s easier to catch bugs and fix them as soon as possible without letting them pile up.

However, in the end, there is a final testing round to ensure a smooth experience and unproblematic launch.

Step 6. Deployment and maintenance

Phew! It’s finally time to launch your B2B web portal. But that doesn’t mean it’s all over: we still need to provide post-launch support, help with data migration if necessary, and track its performance metrics for a while to make sure there are no bugs and the user experience is as smooth as we planned.

What are the key technologies used in B2B portal development?

To extend the domestic analogies, a B2B portal is like a house — it needs a solid foundation and structure. Web development frameworks provide the tools to build the frontend (what users see) and the backend (what powers the system behind the scenes).

1. Frontend technologies

Frontend, or UI(User Interface), is something the users see on the portal. Here is the tech stack commonly used at this stage:

2. Backend technologies

The backend is what powers the system behind the scenes. Here are the technologies used to build it:

3. Database management

Databases store and manage business data, including customer details, transactions, and inventory. Think of a database as a digital warehouse where all information is organized and retrieved when needed.

However, different types of data may require different technologies. Here are the perfect matches:

4. Cloud solutions

Instead of storing data and running applications on a local server (which can crash or slow down), B2B web portals rely on cloud platforms for scalability, speed, and security.

For example, if a wholesale food supplier suddenly receives 10x more orders because of a holiday rush, a cloud solution like AWS automatically scales up to handle the traffic. Without cloud hosting, the portal could crash, leading to lost sales.

5. Security measures

A B2B portal deals with financial transactions, contracts, and supplier details, making it a target for cyber threats. Strong security measures are essential. Here are the ones that commonly prove useful:

How much does each stage of B2B portal development cost?

Now to the (not-so) fun part. The cost of developing a B2B web portal depends on various factors. Here’s a breakdown:

Total cost may range from $75,000 to $180,000, depending on complexity and custom requirements. Let’s dive into why the prices are this way, at every stage.

At the requirements analysis stage, the cost comes from the need to conduct business and market research. Many may think this is something you can easily save on, but it’s much better to spend $3,000 on analysis than $50,000 on a project that turns out to be useless or under-researched.

When it comes to UI/UX design, the cost depends on how unique and sophisticated the prototype is. Highly customized designs with complex dashboards or, say, multirole user interfaces will inevitably be more expensive than basic layouts. But when you’re thinking big, you can’t always go basic.

The cost of the development phase, which is the longest and most expensive, is directly related to the previous step. If you have a unique and complex layout, it would cost a lot of money to bring it to life — prices can reach up to $150,000, depending on the tasks. However, basic B2B portals with standard e-commerce features are significantly cheaper than complex portals with AI-driven analytics.

In later stages, the process may become less costly. Depending on your goals, you may not need to integrate at all, and testing may not reveal any bugs. Then it’s just a matter of deployment and maintenance — although this part of the budget will inevitably become an annual one if you’re planning for the long term.

Conclusion

Building a B2B web portal is more than just creating a digital space for transactions. It’s about taking your business to a new digital level. Whether you’re looking to automate workflows, integrate with existing systems, or scale the whole thing, the right portal can transform the way you do business.

Of course, development is no small feat. From choosing the right technologies to ensuring smooth integrations, every stage requires strategic planning and expert execution. That’s where Purrweb comes in. Our team is no stranger to creating intuitive, scalable, secure B2B portals that align perfectly with your business needs.
