Experience Cloud vs Custom Portals: Making the Right Choice

You need to give your customers, partners, or community members access to information and functionality from your Salesforce org. Maybe it's a customer self-service portal, a partner relationship management system, a member community, or a distributor ordering platform.

You have two fundamental paths:

1. Use Salesforce Experience Cloud (formerly Community Cloud) to build a portal within the Salesforce ecosystem
2. Build a custom portal using external web technologies that integrate with Salesforce via APIs

Both approaches work. Both have successful implementations. But they have radically different cost structures, capabilities, development timelines, and long-term implications.

This guide will help you understand the true comparison—not just the marketing promises—so you can make an informed decision for your specific situation.

What is Experience Cloud?

Salesforce Experience Cloud is a platform for creating digital experiences (portals, websites, mobile apps) that connect directly to your Salesforce data and processes.

Think of it as "Salesforce for external users." You can create branded portals where customers, partners, or community members can:

• Log in to view their data (orders, cases, account information)
• Submit requests (support cases, orders, applications)
• Access resources (knowledge articles, documents, training materials)
• Collaborate with your team and each other
• Complete transactions (purchases, renewals, bookings)

It's all built on top of your existing Salesforce org, using the same data model, security rules, and automation you've already configured.

Experience Cloud Editions and Pricing

Experience Cloud comes in several flavors:

Customer Community ($2 per login/month, or $5/member/month):

• External users can view their related data
• Submit cases and track status
• Access knowledge articles
• Basic self-service functionality

Partner Community ($2 per login/month, or $5/member/month):

• Everything in Customer Community
• Partners can manage their own opportunities and leads
• Collaborative selling features
• Partner relationship management

Experience Cloud Sites (starts at $25/login/month):

• Full customization using Lightning Web Components
• Advanced integration capabilities
• Tailored member experiences
• Enterprise-grade features

Add-ons: Additional features like enhanced personalization, advanced security, and premium analytics can add to costs.

Important: "Per login" means you only pay when users actually log in each month. "Per member" means you pay for registered users regardless of whether they log in. Choose based on your expected usage patterns.

What is a Custom Portal?

A custom portal is an application you build using standard web technologies (React, Vue, Angular, Node.js, etc.) that integrates with Salesforce through APIs.

Instead of building within Salesforce's platform, you create a completely separate application that pulls data from Salesforce, displays it to users, and writes data back.

For example:

• A React-based customer portal that calls Salesforce APIs to display order history
• A custom-built partner portal that retrieves lead and opportunity data from Salesforce
• A member management system built in Ruby on Rails that syncs with Salesforce contacts and accounts

You control everything—design, functionality, infrastructure, user experience—but you're also responsible for everything.

The Real Comparison: Experience Cloud vs Custom Portals

Let's break down the comparison across the dimensions that actually matter.

Development Cost and Timeline

| Aspect | Experience Cloud | Custom Portal | |--------|-----------------|---------------| | Initial Development Time | 4-12 weeks for standard portal | 12-24+ weeks for full-featured portal | | Development Cost | $10,000 - $40,000 NZD | $40,000 - $150,000+ NZD | | Skillset Required | Salesforce developers (Experience Cloud expertise) | Full-stack developers + Salesforce integration experts | | Time to Launch | Faster (leverage existing Salesforce config) | Slower (build everything from scratch) | | Prototype/MVP Speed | Very fast (can launch basic portal in days) | Slower (weeks minimum for meaningful prototype) |

Why the difference?

With Experience Cloud, you're building on top of existing infrastructure:

• Your data model already exists
• Security and permissions are already configured
• Authentication is built-in
• Workflows and automation already work
• UI components are pre-built

With custom portals, you're building from the ground up:

• Design and implement user authentication
• Build database schema (even if syncing with Salesforce)
• Create API integration layer
• Develop every UI component
• Implement security and authorization
• Build admin interfaces
• Create mobile-responsive design

Bottom line: Experience Cloud gets you to market 2-3x faster and typically costs 50-70% less for initial development.

Ongoing Operating Costs

| Cost Category | Experience Cloud | Custom Portal | |--------------|-----------------|---------------| | Platform Licensing | $2-25/user/month (depending on edition) | $0 (no Salesforce portal licenses needed) | | Infrastructure Hosting | $0 (included in Salesforce) | $200-2,000+/month (AWS, Azure, etc.) | | Maintenance & Updates | $500-2,000/month (admin support) | $2,000-8,000+/month (developer maintenance) | | Security Patches | Automatic (Salesforce handles) | Manual (your team's responsibility) | | Scaling Costs | Linear (per user) | Variable (infrastructure + development) |

Let's model a real scenario:

100 active portal users, moderate complexity:

Experience Cloud:

• Licensing: 100 users × $5/month = $500/month
• Admin support: $1,000/month
• Total: $1,500/month = $18,000/year

Custom Portal:

• Hosting: $500/month (AWS infrastructure)
• Maintenance: $3,000/month (part-time developer)
• Total: $3,500/month = $42,000/year

Over 3 years:

• Experience Cloud: ~$54,000
• Custom Portal: ~$126,000

But here's the nuance: if you have thousands of users, the math changes.

5,000 active portal users:

Experience Cloud:

• Licensing: 5,000 × $5/month = $25,000/month
• Admin support: $2,000/month
• Total: $27,000/month = $324,000/year

Custom Portal:

• Hosting: $3,000/month (scaled infrastructure)
• Maintenance: $5,000/month (dedicated developer)
• Total: $8,000/month = $96,000/year

At high user volumes, custom portals can actually be more cost-effective.

Bottom line: Experience Cloud is usually cheaper for <500 users. Custom portals can be cheaper at scale (1,000+ users), but you need to factor in higher build costs and risks.

Maintenance Burden

Experience Cloud:

✅ Automatic updates: Salesforce releases new features three times per year; your portal gets them automatically

✅ Security patches: Salesforce handles infrastructure security

✅ Compliance: Salesforce maintains SOC 2, ISO certifications, GDPR compliance

✅ Performance optimization: Salesforce manages servers, CDN, database optimization

❌ Limited control: You're dependent on Salesforce's release schedule and priorities

❌ Occasional breaking changes: Salesforce updates can sometimes require adjustments to your customizations

Custom Portal:

❌ Manual updates: You must update frameworks, libraries, and dependencies

❌ Security responsibility: You're responsible for patching vulnerabilities, managing certificates, securing infrastructure

❌ Compliance burden: You must ensure and document compliance with regulations

❌ Performance management: You optimize databases, manage caching, scale infrastructure

✅ Full control: Update on your timeline, use exactly the tools you want

✅ Stability: No forced updates; change only when you decide

Real example: A client built a custom portal in 2019 using React 16 and Node.js 10. By 2024, both were outdated with known security vulnerabilities. They needed to invest $35,000 to update to current versions, refactor deprecated code, and test everything.

An Experience Cloud portal from the same era received automatic updates and security patches with zero additional investment.

Bottom line: Experience Cloud has lower ongoing maintenance burden for most organisations. Custom portals require dedicated technical resources for ongoing upkeep.

Customization and Flexibility

Experience Cloud:

✅ Pre-built components: Drag-and-drop page builder with ready-made components (case lists, article viewers, product catalogs)

✅ Branding: Customizable themes, colors, logos, fonts

✅ Lightning Web Components: Build custom components that integrate seamlessly

✅ Salesforce integration: Native access to all Salesforce objects, workflows, and data

❌ Platform constraints: Limited to what Salesforce's platform supports

❌ Design limitations: While flexible, you're working within Salesforce's design system

❌ Complexity ceiling: Extremely complex, unique interactions may be difficult or impossible

Custom Portal:

✅ Unlimited design freedom: Any design, any interaction, any user experience you can imagine

✅ Technology choice: Use any framework, library, or tool

✅ Integration flexibility: Integrate with any system (not just Salesforce)

✅ Performance optimization: Optimize exactly for your use case

❌ Everything is custom: What would be a pre-built component in Experience Cloud requires custom development

❌ Salesforce integration overhead: Every Salesforce interaction requires API calls, authentication, error handling

When Experience Cloud's customization is sufficient:

• Customer self-service portals (case submission, knowledge articles, account info)
• Partner portals (opportunity collaboration, deal registration, resource access)
• Community forums (discussions, user-generated content)
• Training and certification portals
• Standard e-commerce (with some limitations)

When you might need custom portal flexibility:

• Highly unique user experiences that don't fit standard patterns
• Complex, multi-step workflows with heavy custom logic
• Integration with many non-Salesforce systems as primary data sources
• Mobile-first applications requiring offline-first architecture
• Real-time collaboration tools (chat, video, collaborative editing)

Bottom line: 80% of portal use cases fit within Experience Cloud's capabilities. The 20% that don't genuinely require custom development.

Security and Permissions

Experience Cloud:

✅ Inherits Salesforce security: Object-level, field-level, record-level security all work the same as internal Salesforce

✅ Single sign-on: Easy integration with SSO providers (Google, Microsoft, Okta)

✅ Audit trails: Complete logging of user actions

✅ Proven at scale: Trusted by thousands of enterprises

❌ License-driven costs: More secure (authenticated) users = higher costs

❌ Sharing model complexity: Salesforce sharing can be complex to configure correctly

Custom Portal:

✅ Tailored security: Build exactly the security model you need

✅ Flexible authentication: Implement any auth system (though this is also a burden)

❌ Security is your responsibility: Vulnerabilities, data breaches, compliance failures are on you

❌ Complex permission logic: Must build and maintain all permission checking in your code

❌ API security: Must secure API endpoints, manage tokens, prevent abuse

Real example: A healthcare provider needed HIPAA-compliant patient portal. Experience Cloud provided built-in compliance features, audit logging, and field-level encryption. A custom portal would have required extensive security development and ongoing compliance auditing.

Bottom line: Unless you have unusual security requirements, Experience Cloud's proven security model is safer and easier to manage.

Mobile Experience

Experience Cloud:

✅ Responsive by default: Templates are mobile-responsive out of the box

✅ Salesforce Mobile Publisher: Create branded mobile apps without coding

✅ Progressive Web App support: Modern web capabilities (offline access, push notifications)

❌ Mobile-first limitations: Not purpose-built for complex native mobile experiences

❌ Performance: Can be slower than optimized native apps

Custom Portal:

✅ Native mobile apps: Build true iOS/Android apps with full native capabilities

✅ Optimized performance: Purpose-built for mobile can be much faster

✅ Offline-first: Full control over offline data sync and caching

❌ Higher development cost: Native mobile development is expensive ($50,000-150,000+ per platform)

❌ Separate maintenance: iOS and Android apps require separate updates and testing

Bottom line: For responsive web portals accessed on mobile browsers, Experience Cloud is excellent. For complex native mobile apps requiring offline-first architecture, custom development may be needed.

Scalability

Experience Cloud:

✅ Salesforce infrastructure: Leverages enterprise-grade, globally distributed infrastructure

✅ Proven at scale: Powers portals with millions of users

✅ Automatic scaling: No infrastructure management needed

❌ Cost scaling: Costs scale linearly with users (can get expensive)

❌ API limits: High-traffic portals can hit Salesforce API limits

Custom Portal:

✅ Cost control at scale: Can be more economical with thousands of users

✅ Performance optimization: Can optimize for your specific traffic patterns

❌ Scaling complexity: You manage infrastructure scaling, database optimization, caching strategies

❌ Uptime responsibility: You ensure availability and disaster recovery

Bottom line: Both can scale to millions of users. Experience Cloud is easier but more expensive at high volumes. Custom portals are complex but potentially more cost-effective at scale.

Integration with Salesforce

Experience Cloud:

✅ Native integration: Direct access to Salesforce data, workflows, and automation

✅ Real-time updates: Changes in Salesforce instantly reflect in portal

✅ No API limits internally: Portal users accessing Salesforce data don't count against API limits

✅ Automatic relationship handling: Complex Salesforce relationships work automatically

Custom Portal:

❌ API-dependent: Every interaction requires API calls

❌ API limits: High usage can hit daily API call limits

❌ Sync complexity: Must build sync logic, handle conflicts, manage data freshness

❌ Relationship complexity: Must manually handle Salesforce's complex relationship model

❌ Authentication overhead: Must implement OAuth flows, manage session tokens

Real example: A distributor portal needed to show:

• Customer account details
• Related contacts
• Order history
• Case status
• Product catalog
• Custom pricing based on account tier

In Experience Cloud, this is 2-3 days of configuration using standard components and relationships.

In a custom portal, this is 2-3 weeks of development building API calls, handling pagination, caching data, managing relationships, and handling errors.

Bottom line: If Salesforce is your primary data source, Experience Cloud's native integration is vastly simpler and more reliable.

Development Skillset Required

Experience Cloud:

Skills needed:

• Salesforce administration
• Lightning Web Components (for custom components)
• Apex (for custom backend logic)
• Experience Cloud-specific knowledge

Availability of skills: Moderate. Salesforce developers with Experience Cloud expertise are less common than general web developers but easier to find than 5 years ago.

Training curve: Salesforce admins can build basic portals with training. Complex portals require developer skills.

Custom Portal:

Skills needed:

• Full-stack web development
• Frontend framework (React/Vue/Angular)
• Backend development (Node.js/Python/Java/C#)
• Salesforce API integration
• DevOps and infrastructure management

Availability of skills: High. General web developers are plentiful.

Training curve: Standard web development, but Salesforce integration adds complexity.

Bottom line: Custom portals require broader skillsets but skills are more common. Experience Cloud requires specific Salesforce expertise but narrower skillset.

Real-World Scenarios: Which to Choose?

Let's walk through specific use cases and the right choice for each.

Scenario 1: Customer Self-Service Portal

Requirements:

• 500 customers need to log in
• View their account info, orders, invoices
• Submit support cases
• Access knowledge base articles
• Track case status

Recommendation: Experience Cloud (Customer Community)

Why: This is the textbook use case for Experience Cloud. All functionality is available out of the box with minimal customization. Development time: 4-6 weeks. Cost: $10,000-15,000 implementation + $2,500/month licensing.

Custom portal would cost $60,000+ to build with minimal added value.

Scenario 2: Partner Relationship Management Portal

Requirements:

• 200 partners need access
• View and manage their opportunities in Salesforce
• Register deals
• Access marketing materials and training
• Collaborate with your internal sales team
• Download co-branded collateral

Recommendation: Experience Cloud (Partner Community)

Why: Partner communities are a core Experience Cloud use case with pre-built functionality. Development time: 6-10 weeks. Cost: $15,000-25,000 implementation + $1,000/month licensing.

Custom portal would require extensive collaboration features and Salesforce integration that would take 16+ weeks and $80,000+.

Scenario 3: High-Volume Customer Portal (10,000+ users)

Requirements:

• 10,000+ customers accessing portal monthly
• View account balance, transaction history
• Make payments
• Update account information
• Download statements

Recommendation: Depends on usage patterns

Analysis:

If all 10,000 log in monthly:

• Experience Cloud: 10,000 × $5 = $50,000/month = $600,000/year
• Custom portal: ~$8,000/month operating cost = $96,000/year + $80,000 build = $176,000 year 1

At this scale, custom portal may be more economical long-term.

If only 1,000 log in monthly (login-based pricing):

• Experience Cloud: 1,000 × $2 = $2,000/month = $24,000/year
• Custom portal: $96,000/year + build cost

Experience Cloud is far more economical.

Bottom line: Run the numbers based on actual expected usage.

Scenario 4: Complex, Unique User Experience

Requirements:

• Multi-step application process with complex conditional logic
• Integration with document signing (DocuSign)
• Integration with payment processing (Stripe)
• Integration with identity verification services
• Custom animations and interactive UI elements
• Offline mobile app capability

Recommendation: Custom Portal

Why: While Experience Cloud could handle pieces of this, the highly customized UX, multiple integrations with non-Salesforce systems, and offline mobile requirements make custom development more practical. You'll have more control and a better end-user experience.

Cost: $100,000-150,000 to build, but worth it for the competitive advantage of the superior UX.

Scenario 5: Member Community with Forums and Content

Requirements:

• 2,000 members
• Discussion forums
• User-generated content
• Member profiles
• Events and registration
• Resource library
• Newsletter subscriptions

Recommendation: Experience Cloud

Why: Community and collaboration features are a strength of Experience Cloud. Forums, user profiles, content management, and gamification are all built-in. Development time: 8-12 weeks. Cost: $20,000-35,000 implementation + $10,000/month licensing.

Custom development would require building forum software, user management, content systems—a massive undertaking easily exceeding $150,000.

Scenario 6: E-commerce Portal with Salesforce Backend

Requirements:

• Product catalog from Salesforce
• Shopping cart and checkout
• Order management
• Account-specific pricing
• Integration with payment gateway
• Inventory checking

Recommendation: Hybrid approach or Custom Portal

Why: While Experience Cloud can handle basic commerce, most serious e-commerce needs will outgrow it. Consider:

• Small-scale B2B commerce (< 100 customers, limited catalog): Experience Cloud works
• Complex commerce (large catalog, complex pricing, advanced features): Custom portal or dedicated e-commerce platform (Shopify, WooCommerce, BigCommerce) integrated with Salesforce

Cost for custom e-commerce: $60,000-120,000 depending on complexity.

Decision Framework: 10 Questions to Ask

Use this framework to determine the right choice for your situation:

1. Is Salesforce your primary data source?

Yes → Experience Cloud likely better No (you integrate with many systems) → Custom portal might be better

2. How many active users will you have?

< 500 → Experience Cloud likely more economical 500-2,000 → Run the numbers for both 2,000+ → Custom portal may be more economical long-term

3. How unique is your desired user experience?

Standard portal patterns → Experience Cloud Highly unique, brand-critical UX → Custom portal

4. How quickly do you need to launch?

< 3 months → Experience Cloud 6+ months OK → Either could work

5. What's your development budget?

< $50,000 → Experience Cloud $50,000-100,000 → Either could work $100,000+ → Custom portal is feasible

6. Do you have Salesforce expertise in-house or available?

Yes → Experience Cloud is easier to maintain No → Custom portal might be easier with standard web developers

7. How important is mobile experience?

Responsive web is fine → Experience Cloud Need native apps with offline → Custom portal

8. How complex is your required functionality?

Standard CRM portal features → Experience Cloud Complex, multi-system workflows → Custom portal

9. What's your long-term strategy?

All-in on Salesforce → Experience Cloud Platform-agnostic → Custom portal

10. How critical is time-to-market vs long-term cost?

Need fast launch → Experience Cloud Willing to invest upfront for lower long-term cost → Custom portal

The Hybrid Approach: Best of Both Worlds?

Some organisations use a hybrid model:

Experience Cloud for authenticated portal + Custom public website that integrates with Salesforce

Example: A SaaS company uses:

• Custom-built marketing website and signup flow (for ultimate flexibility)
• Experience Cloud for customer portal post-signup (for ease of Salesforce integration)

This gets the UX flexibility where it matters most (acquisition) while leveraging Experience Cloud's efficiency for ongoing customer management.

Another approach: Start with Experience Cloud, migrate to custom later if needs outgrow the platform.

The risk: Migration is expensive. Better to choose correctly upfront if possible.

Getting Started: Next Steps

Whichever path you choose, success requires proper planning and execution.

For Experience Cloud Implementation:

1. Define requirements clearly: What do users need to do? What data do they need to access?

2. Choose the right edition: Customer, Partner, or Experience Cloud Sites?

3. Plan information architecture: How will content and data be organized?

4. Design user experience: Even with templates, UX planning matters

5. Configure security properly: Sharing rules, profiles, permissions sets

6. Build and test iteratively: Launch MVP, gather feedback, improve

7. Train your team: Admins need Experience Cloud-specific knowledge

For Custom Portal Development:

1. Define detailed requirements: Custom builds need more specificity

2. Choose technology stack: Frontend framework, backend language, hosting platform

3. Design Salesforce integration architecture: API calls, authentication, data sync strategy

4. Build security model: Authentication, authorization, data protection

5. Develop in phases: MVP first, then iterate

6. Plan for maintenance: Who will maintain code, update dependencies, manage infrastructure?

7. Document everything: Custom code requires thorough documentation

Our Recommendation: When to Choose What

Based on our experience implementing both approaches for dozens of clients:

Choose Experience Cloud if:

• Your primary use case is customer/partner/community portal
• Salesforce is your primary data source
• You want faster time to market
• You have < 2,000 regular active users
• You value lower ongoing maintenance burden
• Your desired UX fits within platform capabilities
• You have (or can access) Salesforce expertise

Choose Custom Portal if:

• You have 5,000+ active users (run cost analysis)
• You require highly unique UX that's brand-critical
• You integrate heavily with many non-Salesforce systems
• You need native mobile apps with offline capability
• You have (or can access) full-stack development expertise
• You're willing to invest upfront for potential long-term savings
• Platform independence is strategically important

For 75% of organisations, Experience Cloud is the right choice. It's faster, cheaper initially, easier to maintain, and perfectly capable for standard portal use cases.

Custom portals make sense in specific scenarios where the UX advantage, cost savings at scale, or technical requirements justify the higher investment and complexity.
