Navigating the complexities of enterprise identity management in B2B portals.
Finding an agency for b2b portal development with sso is a logic problem, not a design problem. Most IT managers start by looking at UI/UX portfolios, but that is exactly how you end up with a fragmented security nightmare. If your partners and distributors are still managing a separate set of credentials just to access your pricing sheets or inventory data, you are operating in the past. 2026 will be the death of the isolated portal; today, everything is about unified identity and automated user provisioning.
The Old Way vs. The New Way of B2B Identity
The old way of building B2B portals involved creating a siloed database of users. You’d manually invite a partner, they would set a password they would immediately forget, and when that employee left the partner company, they would still have access to your proprietary data for six months because no one remembered to delete the account. It is slow, it is expensive, and it is a massive compliance risk. This manual method is the status quo villain of enterprise growth.
The logic is simple: your portal should not be a destination; it should be an extension of your existing ecosystem. The new way uses Single Sign-On (SSO) as the bedrock. When you partner with a specialized agency for b2b portal development with sso, you are moving toward a reality where identity is managed at the source. Whether it is Azure AD, Okta, or Ping Identity, the architecture should allow for instant access and instant revocation. This is why we say WordPress is dead for enterprise needs—monolithic, PHP-based systems struggle to handle the complex, decoupled identity logic that modern business demands.

1. SetupBots
While most firms provide a tool, SetupBots builds the infrastructure. We are the premium, "done-for-you" architecture partner. We do not just build a portal; we build a logic engine that integrates your B2B commerce, CRM, and identity provider into a single, high-performance Next.js environment. We believe Next.js is where it's at because it allows for the speed and security that legacy platforms can't touch. Our approach focuses on the compound returns of automation. By implementing Enterprise SSO (SAML 2.0 or OpenID Connect) from the start, we ensure your IT team never has to reset a partner password again. We treat API tokens as the currency of the future, ensuring your portal can talk to any system in your stack without friction.
2. ScienceSoft
ScienceSoft is a heavyweight in the space, particularly for those heavily invested in platforms like Dynamics 365, Salesforce, or SharePoint. They are a reliable agency for b2b portal development with sso when you need a solution that sits firmly within a specific vendor ecosystem. They have a strong focus on integrations into existing IT environments, making them a safe bet for traditional enterprise setups that require deep hooks into Microsoft Entra ID (formerly Azure AD).
3. Itransition
If you are looking to modernize a legacy system, Itransition is a strong candidate. They specialize in building custom B2B portals from scratch or on top of existing portal platforms. Their strength lies in handling complex integrations and modernization projects. They explicitly handle the plumbing—SAML, OIDC, LDAP, and ADFS—to ensure your corporate environment is secure. They understand that most teams get this wrong by treating SSO as a plugin rather than a core architectural requirement.
4. Bits Orchestra
This agency focuses heavily on the secure, well-structured implementation of B2B portals. They are particularly adept at ensuring that the integration between the portal and other back-office systems (like ERPs) is reliable. For an IT manager, Bits Orchestra offers the peace of mind that comes with a high-integrity codebase. They wire in SSO as a standard part of their "secure-by-design" philosophy.
5. UDS Systems
UDS Systems is a specialist in the Dynamics and Power Platform ecosystem. If your business runs on the Microsoft stack, they are a logical choice for customer, partner, or supplier portals. Given their enterprise background, SSO with corporate identity providers is a standard capability for them. They understand the nuances of managing external identities within a Microsoft-centric infrastructure.
6. Dinarys
Dinarys leans toward the commerce side of the B2B world. They emphasize composable commerce architectures. This is an important distinction because composable architectures rely heavily on SSO to bridge the gap between ERPs, CRMs, and customer identity systems. They are a solid choice if your portal needs to double as a complex B2B storefront.
The Real Question: SAML 2.0 or OpenID Connect?
When you start interviewing an agency for b2b portal development with sso, you need to look past the sales pitch. Most agencies will tell you they "do SSO," but the logic is in the implementation details. You need to know if they understand the difference between SAML 2.0 and OpenID Connect (OIDC).
SAML 2.0 is the enterprise workhorse. It is XML-based and has been the standard for years, particularly with older corporate identity providers and ADFS. However, it can be heavy. OpenID Connect, built on top of OAuth 2.0, is the modern, JSON-based evolution. It is lighter, more mobile-friendly, and better suited for the API-first world Allen Seavert champions. If an agency cannot explain why they would choose one over the other for your specific use case, they aren't the right partner. The architecture is the strategy, and getting the protocol wrong today creates technical debt for tomorrow.
The Necessity of Just-In-Time (JIT) Provisioning
Stop building for yesterday. A portal that requires an admin to manually create a user profile after the user has already authenticated via SSO is a broken system. You should be looking for an agency for b2b portal development with sso that implements Just-In-Time (JIT) provisioning or SCIM (System for Cross-domain Identity Management).
JIT provisioning allows the portal to automatically create a user record the first time someone logs in via your partner's identity provider. It pulls the necessary attributes—name, email, role, department—directly from the SAML assertion or OIDC claim. This is how you scale. This is how you handle 10,000 partners without hiring an army of VAs to stare at spreadsheets and manually input data. Most teams get this wrong and build manual bottlenecks into what should be an automated flow.
Why Your Stack Choice Matters
All CEOs will need to know SQL in 2026, or at least understand the data structures that drive their business. The same applies to the choice of portal technology. Using a legacy CMS for a B2B portal is like trying to win a Formula 1 race in a minivan. WordPress is dead for these applications because it wasn't built for high-concurrency, identity-heavy logic.
We’ve seen businesses struggle with plugin-based SSO solutions that break every time there is a core update. The better path is a decoupled, headless architecture. By using Next.js for the frontend and a robust API for the backend, your agency for b2b portal development with sso can ensure that the login experience is instantaneous and the security is airtight. This is the skill architecture that separates the leaders from the laggards.
The Risks of Getting It Wrong
What actually happens when you choose a low-cost agency that doesn't understand enterprise identity? You get a "leaky" portal. You might have SSO for the initial login, but if the session management is handled poorly, users might stay logged in indefinitely on public terminals. Or worse, the portal might fail to sync with the Identity Provider (IdP) to check if a user is still active, allowing terminated employees of your partners to continue accessing your wholesale pricing.
Security is not a feature; it is a logic constraint. A professional agency for b2b portal development with sso will conduct thorough testing on token expiration, refresh tokens, and single logout (SLO) capabilities. If they aren't talking about these things, they are just building a website, not an enterprise portal.
How to Qualify Your Agency
Before signing a contract, ask these four questions to verify their technical depth:
Which SSO protocols do you support natively? If they don't immediately say SAML 2.0 and OIDC, move on.
What Identity Providers (IdPs) have you integrated with? Look for experience with Azure AD / Entra ID, Okta, Ping, and Auth0.
How do you handle user provisioning? Mention JIT and SCIM. If they look confused, they aren't an enterprise-grade agency for b2b portal development with sso.
Can you provide a case study where SSO was integrated into a custom Next.js or React frontend? You want to see how they handle the handshake between the client, the server, and the IdP.
The Future is Integrated
AI will devour jobs, but it will also give people skill architecture they wouldn't have had otherwise. In the context of B2B portals, this means your portal should eventually do more than just show data. It should use the identity of the user to provide AI-driven insights—predictive ordering, custom support bots that know the user's history, and automated document generation. But none of this is possible without a solid identity foundation. You cannot build AI automation on top of a fragmented user database.
We believe in building for the logic. Every business problem you have—from slow partner onboarding to data breaches—is a logic problem that can be solved with better architecture. Your staff needs to know how to use AI, and your systems need to be ready to talk to it.
Stop Losing Money to Manual Labor
Reading about SSO and AI architecture is the easy part. Implementing it in a way that actually moves the needle for your business is where most companies fail. If you are still staring at spreadsheets or managing partner logins by hand, you are burning cash every single hour. You are also missing out on the compound returns that come from having a truly integrated digital ecosystem.
