Portal development companies: 9 vendors compared for 2026

What portal development companies build

Portal development companies build logged-in web applications where customers, partners, or employees see their own data and complete tasks themselves. Typical examples are a customer portal, a self-service portal, a B2B partner portal, and an employee portal. Projects stall when buyers scope a portal as a website with a login, because permissions, identity, and back-office integration carry most of the work.

The scope usually spans a discovery phase, permission and identity design, ERP and CRM integration, interface build, WCAG 2.2 accessibility testing, and post-launch support.

Authenticated web applications and portals typically include role-based access, identity integration, and ERP and CRM connectivity for enterprise clients. Portals are often paired with a companion enterprise mobile application, so teams planning that route should settle architecture, security, and integration questions early.

We recommend settling role-based access control and single sign-on (SAML and OpenID Connect) design first, because both set the integration and testing scope that follows. Role models tend to grow from a handful of roles to dozens once partner organizations join, and each customer's identity team has to approve its own federation setup.

A website serves anonymous visitors the same content. A portal authenticates a known user, shows data scoped to that user's organization and role, and lets them write back: approve an order, open a ticket, update a record.

Gated pages on a CMS cover read-only document access, but live ERP or CRM data with per-organization permissions calls for portal engineering. How much engineering depends on the number of user organizations, the identity providers involved, and whether the back-office systems expose APIs.

Types of portals and what each one demands technically

Portal types differ most in authentication and tenancy. A customer portal serves individuals of one organization through one identity store, while a B2B partner portal serves many companies, each with its own users, hierarchy, and often its own identity provider. Employee, vendor, patient, and self-service portals sit between those poles.

Customer portal development company

A customer portal development company should show it can run a single-organization model: one user directory, email or social login, MFA, and role-based access control with a short role list such as account owner and viewer. The hard parts are account linking, recovery flows, and CRM and billing integration. Choose the assurance level from what the portal exposes, using NIST SP 800-63.

Salesforce Experience Cloud fits when the CRM is already Salesforce. Liferay or a custom build fits when the portal carries workflows the CRM does not model.

B2B portal development companies

B2B portal development companies are tested on multi-tenancy. Each partner organization needs its own administrator, a parent-regional-branch hierarchy, isolated data, and single sign-on (SAML and OpenID Connect) against the partner's own identity provider, so offboarding happens on the partner's side.

Our view is that role-based access control alone produces a role explosion across hierarchies. Add attribute rules keyed to organization and region. Liferay's organization model and Salesforce Experience Cloud partner experiences cover common cases. Many distinct identity providers usually push teams toward a custom build on an identity broker.

The caveat: with only a handful of partners, per-partner federation is overbuilt. A shared login with enforced MFA ships faster.

The remaining types compared side by side:

Portal type	Authentication	Tenancy	Technical demand	Vendor tags
Employee portal	SSO through the corporate IdP (SAML or OpenID Connect)	Single organization	Directory-driven roles, HR and ERP integration	Microsoft SharePoint, Liferay
Vendor portal	Federated or local accounts with MFA	Multi-tenant by supplier	Purchase order and invoice flows, ERP integration	Custom build, Liferay
Patient portal	Identity proofing, MFA	Single organization, per-patient record access	HIPAA right of access, audit logs, EHR integration	Healthcare-specialist or custom build
Self-service portal	Inherits from the host portal	Follows the host portal	Workflow engine, knowledge base, ticketing and CRM integration	Salesforce Experience Cloud, Liferay

When shortlisting vendors, ask which row of this table each one has shipped, beyond the platforms it resells.

How portal vendors handle ERP, CRM and legacy integration

Portal vendors handle ERP and CRM integration by auditing API readiness first, then assigning each data object a sync model: real-time, event-driven, or batch. The audit belongs in the discovery phase. It records, for each system, the documented endpoints, authentication method, rate limits, sandbox availability, and whether write-back is supported.

Real-time calls through an API gateway suit lookups such as pricing and credit limits. Event-driven sync (webhooks or a message broker) suits status changes such as order shipped. Nightly batch ETL suits catalogs and invoice history.

The choice per object depends on how stale the data may be and how much load the source system tolerates. Single sign-on (SAML and OpenID Connect) is part of the same audit, because the portal's role-based access control depends on the claims each identity provider sends. The three failure modes below are the ones we would probe first:

Failure mode	What breaks	Vendor mitigation	Question that exposes a weak answer
Undocumented legacy APIs	SOAP services, stored procedures, or file drops behave differently from what the one remaining developer remembers	Characterization tests against the legacy system, then an API facade behind the gateway so the portal never calls it directly; contract tests catch drift	"Which legacy endpoints did you reverse-engineer last time, and how do you detect a changed contract?" Answers like "we'll read the database directly" are a warning
Batch-only ERP exports	Users see yesterday's inventory or balance; re-running a failed file creates duplicates	Show an "as of" timestamp, key imports on the ERP record ID so reloads are idempotent, and use a live read-through call for the few fields that must be current	"What does a user see between exports, and what happens when the same file loads twice?"
Multiple partner identity providers	Each partner's SAML or OpenID Connect provider names attributes differently, rotates signing certificates on its own schedule, and drifts on clock skew	An identity broker such as Keycloak normalizes claims into one internal role model, with alerts on certificate expiry. Assertion handling should follow NIST SP 800-63C	"How do you onboard the tenth partner identity provider, and who is paged when a signing certificate expires?"

The advice shifts with your stack. If the ERP is a current SaaS product with a maintained REST API, the legacy row mostly disappears, and a portal with one workforce identity provider does not need a broker. For a B2B partner portal with many companies, we recommend treating the broker as a day-one requirement.

Ask any shortlisted vendor to show a runbook from a previous integration: the retry policy, the dead-letter queue, and the reconciliation report between portal and ERP. A vendor that has run these in production can produce them quickly.

What a portal development engagement looks like, and what drives cost

A portal development engagement typically runs 5-8 months from discovery phase to launch, and four factors set the price: role count, integrations, compliance scope, and upstream API quality, in our planning experience.

The ranges below are our planning estimates for a mid-size portal with one or two ERP or CRM connections, not published benchmarks.

Phase	Duration (estimate)	Output
Discovery	2-4 weeks	Role matrix, integration audit, scoped backlog
Design and architecture	3-5 weeks	Identity model, data flows, UX prototypes
Build	10-16 weeks	Working portal, integrations, admin console
Hardening	3-5 weeks	Security testing against OWASP ASVS, WCAG 2.2 checks, load tests
Launch and hypercare	2-4 weeks	Production cutover, defect triage

A baseline feature set for most portals:

• Single sign-on over SAML or OpenID Connect
• Role-based access control, with attribute rules where roles multiply
• Role-specific dashboards
• Search across content and connected records
• Workflow with approvals
• Alerts and notifications
• An admin console for users, roles, and content

What drives cost

1. Roles: Each distinct role adds permission rules, a dashboard variant, and test cases. Role-based access control that depends on tenant or record attributes costs more than flat roles.
2. Integrations: A read-only batch feed is the cheapest ERP and CRM integration. Bidirectional write-back with real-time sync costs the most, because conflict handling and retries must be built and tested.
3. Compliance scope: HIPAA for patient portals or a WCAG 2.2 AA commitment adds audit logging, encryption controls, and independent testing.
4. Upstream API quality: An undocumented or rate-limited legacy ERP forces a middleware layer. The discovery audit should price that layer before the build starts.

Custom build or platform

The trade-offs side by side:

Option	Cost shape	Fits	Strain point
Custom build	Highest upfront, no per-user licence	Unusual workflows, deep write-back, many tenants	You own patching and upgrades
Liferay DXP	Subscription plus implementation partner	Configurable partner or employee portals	Heavy customization raises upgrade cost
SharePoint	Bundled with Microsoft 365 for internal users	Employee portal in a Microsoft shop	External identity and customer-facing UX need extra work
Salesforce Experience Cloud	Per-login or per-member licences	Customer or self-service portal on Salesforce CRM	Licence cost grows with external users; ERP data needs a separate integration layer

We recommend a platform when the portal is mostly a front end on one system of record, and a custom build when workflows or tenancy are the product. Model three-year licence cost at your projected external user count before deciding.

Login-based Experience Cloud licenses provision 20 login licenses for each monthly login purchased, so 1,000 logins yields 20,000 licenses (Salesforce Help: Experience Cloud User Licenses, 2025).

After hypercare, support usually moves to a retainer with severity tiers. Get response and resolution times per tier in writing (an illustrative P1 target is a one-hour response), and confirm who owns hosting, since uptime depends on it.

Checklist for verifying vendor claims

Run these checks before a shortlist call:

1. Portal type match: Ask for a live or demoed portal with your user type (customer, B2B partner, or employee), not a marketing site or mobile app.
2. Integration evidence: Ask which ERP or CRM was connected, through an API gateway, event-driven sync, or batch ETL, and who owned the upstream API changes.
3. Identity design: Ask how they handled SAML or OpenID Connect federation and role-based access control, and which OWASP ASVS level they tested against.
4. Compliance proof: For healthcare, request the vendor's HIPAA safeguards documentation and signed BAA terms. For public-facing portals, ask for a WCAG 2.2 conformance report.
5. Reference call: Speak to a client whose portal has been live for 12 months or more, because launch-day references hide maintenance cost.
6. Outcome figures: Ask for measured results from a past portal, such as adoption or support-ticket change, with the baseline and the measurement period.
7. Profile cross-check: Compare the vendor's team-size and project-count claims against its Clutch profile, noting the access date.

Check ERP integration first, because it carries the most delivery risk on a portal project.

Conclusion

The right portal development partner depends on who your portal serves, which systems it has to connect to and which compliance rules apply. The nine companies above cover different ground: B2B commerce portals, patient portals, banking portals, MVP-stage products and enterprise platforms.

Shortlist two or three whose case studies match your portal type and your ERP or CRM, then run the checklist above before you compare prices. Integration and identity work decide most of the cost and risk, so weigh them above the stack list.
