These are some common scenarios where we often guide customers to make portals.
If you work with channel partners, distributors, or affiliates, a partner portal streamlines processes. These portals enable secure collaboration and information sharing with business partners. Through a partner portal, resellers or agents can access marketing materials, register deals, submit leads, or track joint projects. Partner portals help you empower your partners with the tools and information they need to sell or work with your product more effectively.
Customer Reviews
I was astonished that, in such a short period of time, something that other companies had taken months to understand, this company was able to execute. Since then, we have never looked anywhere else. I would never consider another company. This is how much we believe in them.
The other agencies we looked at, frankly, wanted to tell us how great they were. Sembit instead asked a lot of probing questions and provided the kind of consultation that really made us comfortable in hiring them.
It's been excellent every step of the way. The initial conversations were excellent — we had an instant human connection. In addition to being professional, they also had a human touch that's irreplicable.
I've really loved working with them. Sembit always delivers what they say they're going to deliver, in the time they say they'll deliver it. Whenever we have a deadline for a task delivery, the team gives us detailed and frequent updates about their progress. It's been a great partnership.
Sembit's team really took on the mindset of our business which resulted in a better product with thoughtful decisions from developers. We have been able to have healthy discussions about the pros and cons of a design choices which ultimately makes a better product in the long run.
Sembit has over-delivered on their promises at every step of the process. They've come in ahead of schedule and below budget, and they let us know if we are asking for too much. They are clear communicators, and it made a world of difference for our company.
At Sembit, we've built fully-custom B2B web portals across a number of industries like manufacturing, healthcare, and logistics. Every case study showcases unique workflows and integration needs.
One example is our work with Hino Motors, a Toyota subsidiary shipping heavy-duty truck parts across the world. We built a custom portal where dozens of users across the Caribbean and Latin America log in via mobile or desktop, place parts orders, and behind the scenes the portal interfaces with an IBM i (AS400) mainframe system. This legacy integration meant taking a green-screen system and wrapping it in a user-friendly web experience, empowering a whole network of repair shops and distributors to manage logistics with ease via a portal. Despite the complexity under the hood, the result is a fast, mobile-friendly custom portal interface that transformed how Hino handles ordering, tracking, and fulfillment.
For a Fortune 50 medical company, we created a physician-facing portal for ordering medical devices, managing profiles, and accessing sales collateral, all through a single integrated interface. This B2B portal became the central point for physician customers as well as sales staff to place orders. The portal integrated with Salesforce and JD Edwards, their backend ERP system.
Also in healthcare, we developed a HIPAA-compliant patient portal, integrating with their EMR system to give patients secure access to medical data and physician communication.
Whether the use case is warranty registration, distributor ordering, or medical data visibility, our team handles it end to end., We do UI/UX design, custom portal web development, secure cloud hosting configuration, and long-term support. From onboarding and UI/UX design to secure cloud hosting and long-term support.

Sembit is an Oregon-based software team that specializes in complex B2B web applications, and custom portal development isn't new to us. We're a full-service agency, taking care of design, integrating with your legacy systems, deploying, and providing ongoing maintenance and support. Our developers have been working with web technologies, databases, and legacy systems for decades (ever since they weren't legacy!) This means we are comfortable taking on the tricky integration parts of custom web portals such as IBM i (AS400) or older systems. Because we are a smaller, senior-heavy team, you don't get handed off to junior staff.

A B2B portal needs to pull and push data to your existing business systems. For example, integrating the portal with your ERP (for inventory, orders) and CRM (for customer info) ensures that the data on the portal is always up-to-date and eliminates double entry. We design portals with integration in mind: whether it's connecting to an SAP or Oracle backend, a Salesforce CRM, or any third-party application (payment gateways, shipping providers, analytics tools), the portal will do what you need it to do. This means your stakeholders using the portal will get accurate, real-time information.
If your portal involves selling or ordering products/services, a comprehensive catalog and order management system may be needed. This includes detailed product information (specs, pricing tiers, availability). On the ordering side, custom B2B portals often include specialized cart options vs. generic Shopify options. For example, we built a B2B portal for a company that wanted multiple named shopping carts, something that no standard e-commerce “shopping cart” could provide.
Each portal audience is unique. If the users are out in the field performing inspections or practicing trades, they will have different priorities than procurement specialists or healthcare professionals sitting with dual monitors in an office setting. Furthermore, different demographics and generations each have UI and UX patterns that are the most straightforward to them. We conduct user research and perform user tests to ensure that each portal is easily navigated by the people who will use it most.
We can incorporate features like a knowledge base (with FAQs, guides, documentation) and support ticketing or live chat integration. This means when your client has an issue or question, they can log in to find troubleshooting steps or submit a support request without hassle. For questions that require human help, we integrate support ticketing systems or live chat so users can submit requests directly through the portal, complete with attachments, screenshots, and automated status updates. This centralizes all support interactions inside the portal, instead of scattering information across emails, spreadsheets, or separate tools. By giving your partners and customers clear pathways to self-serve or escalate issues, you reduce support overhead, improve response times, and create a smoother experience for every user who relies on your portal.
Custom B2B portals may require a central repository where users can access product information, marketing materials, technical documents, or training resources. We build or connect to structured document management systems that make it easy to upload and categorize documents. Users can quickly find what they need without digging through emails or outdated PDFs. Permissions ensure that each partner or customer only accesses the content intended for them. This reduces support requests, improves partner enablement, and keeps all stakeholders aligned with the most current information.
Most B2B portals need to be mobile-friendly and responsive. Users are likely engaging with the portal on their phone or tablet as well as desktops and laptops. In some cases, a dedicated mobile app might be recommended for even more convenient access (for example, to send push notifications about order updates or allow offline functionality).
FAQs About Our Custom Web Portal Development Services
Yes. Sembit typically handles portal projects end-to-end. This includes UI and UX design, user research, integration with backend systems, coding, cloud deployment, and long-term support. Most clients come to us for full lifecycle development. We make sure the portal launches smoothly and continues to run reliably.
Yes. Integration is one of the most common reasons companies hire us. We have experience connecting modern web portals to external systems such as IBM i (AS400), Salesforce, EMR systems, and other platforms. We pull data from the systems you already have and present it through a modern, user-friendly interface. Our team is comfortable working with older technology stacks that many firms are not equipped to handle.
Yes, we can develop portals that follow strong privacy, encryption, and security practices, and we deploy them into cloud environments that meet compliance requirements such as SOC 2 and HIPAA. The compliance certification belongs to the cloud provider, not the custom code itself. Our job is to design and develop the portal securely and ensure all data flows are protected. We work with your hosting preferences so your organization maintains full control over compliance.
Yes. Many clients ask if we provide ongoing support after launch, and the answer is always yes. We continue to assist with updates, improvements, cloud configuration, integrations, and troubleshooting. We also help evolve the portal over time as your business needs change. If you prefer, we can hand off support to your internal development team.
Yes. Clients often ask which cloud to use when storing sensitive or regulated data. Azure, AWS and Google Cloud are the most common, but we also work with smaler cloud providers. Each option has strengths in compliance, security, and cost. We help guide you to the right choice for your portal.
Yes. We decouple the web portal from your back-end system to ensure that neither is slowed down by the other. This allows arbitrary scaling by queuing up new transactions, such as orders, and replicating product pricing and inventory information. We can load-test your portal with much higher volume than you currently experience to ensure it is effective for years to come.
Yes. Many companies come to us with an existing portal that needs support, modernization, or ongoing maintenance. We can step in to manage the current system, diagnose issues, stabilize performance, and improve the codebase over time. If needed, we can also plan a gradual transition to a more modern architecture without disrupting your users. Whether the portal was built in-house or by another vendor, we can take it over and keep it running smoothly.
Yes! Every company benefits from a customized system that streamlines interactions between businesses. B2B portals are used across every industry, from manufacturing to healthcare. We have developed portals for ordering systems, warranty management, physician access, patient access, distributors, and extended workforces. Any business that needs customers or partners to log in and do something specific can benefit from a custom portal.
