WordPress vs Custom Website: Which is Right for Your Business?
A plain-English comparison of WordPress and custom-built websites. Learn when each option makes sense, what they really cost, and how to make the right choice for your business.
The Short Answer
Choose WordPress if: You need a blog, simple business website, or online store, and you're comfortable with some limitations in exchange for lower cost and faster launch.
Choose custom if: You need unique functionality, have specific performance requirements, or plan to scale significantly.
But this oversimplifies things. Let's dig into what these options actually mean in practice.
What is WordPress, Really?
WordPress is like a pre-built house that you can customize. The foundation, walls, and plumbing are already there. You pick the paint colors, furniture, and decorations.
The good:
- You can launch a website in days, not months
- Thousands of pre-made designs (themes) to choose from
- Plugins add features without writing code
- Huge community means lots of help available
- Many web agencies know WordPress well
- Your site looks and works like other WordPress sites
- Plugins can slow down your site or conflict with each other
- Security requires constant attention (updates, patches)
- Major customizations often cost as much as building custom
- You're dependent on plugin developers for features
What is a Custom Website?
A custom website is like building a house from scratch. Architects design exactly what you need, builders construct it to your specifications.
The good:
- Built exactly for your needs, nothing more, nothing less
- Typically faster and more secure
- No plugin conflicts or bloat
- Easier to scale and modify long-term
- You own everything, no dependencies
- Higher upfront investment
- Takes longer to build (weeks to months)
- Requires skilled developers
- Changes need developer involvement
Real Cost Comparison
Let's be honest about what things actually cost:
| What You Need | WordPress | Custom |
|---|---|---|
| Simple 5-page business site | 15,000 - 40,000 NOK | 40,000 - 80,000 NOK |
| Business site with blog | 25,000 - 60,000 NOK | 50,000 - 100,000 NOK |
| Online store (simple) | 40,000 - 100,000 NOK | 80,000 - 200,000 NOK |
| Online store (complex) | 80,000 - 200,000 NOK | 150,000 - 400,000 NOK |
| Booking/membership system | 60,000 - 150,000 NOK | 100,000 - 300,000 NOK |
WordPress sites typically need:
- Hosting: 1,000 - 5,000 NOK/year
- Plugin licenses: 2,000 - 15,000 NOK/year
- Security monitoring: 3,000 - 10,000 NOK/year
- Updates and maintenance: 5,000 - 20,000 NOK/year
- Occasional fixes when plugins break: Varies wildly
- Hosting: 1,000 - 8,000 NOK/year
- Maintenance and updates: 5,000 - 15,000 NOK/year
- No plugin licenses or compatibility issues
When WordPress Makes Perfect Sense
1. Content-heavy websites
If your main activity is publishing articles, news, or blog posts, WordPress was literally built for this. The editor is excellent, categories and tags work well, and SEO plugins are mature.
2. Limited budget, need to launch fast
If you have 20,000 NOK and need a website next month, WordPress is your friend. A skilled developer can customize a quality theme and launch quickly.
3. Standard business website
Home page, About, Services, Contact. If that's all you need, WordPress handles it fine. No point over-engineering a simple brochure site.
4. You want to update content yourself
WordPress's admin panel is familiar to millions of people. If you want to add pages, edit text, and upload images without calling a developer, WordPress makes this easy.
When Custom is Worth the Investment
1. Your website IS your product
Building a SaaS platform? A booking system? A customer portal? These aren't "websites" in the traditional sense. They're applications. WordPress wasn't designed for this.
2. Performance matters for your business
If your site needs to load in under 1 second, handle traffic spikes, or work flawlessly on slow mobile connections, custom development gives you control that WordPress can't match.
3. You have unique business processes
"We need users to submit applications, which go to reviewers, who score them, then applicants get notified, and administrators see dashboards..."
This kind of workflow doesn't fit neatly into any WordPress plugin. You'll spend more fighting WordPress than building custom.
4. Security is critical
Banks, healthcare, legal services. If a security breach would be catastrophic, you want a minimal attack surface. Every WordPress plugin is a potential vulnerability.
5. Long-term growth plans
Starting small but planning to scale? Custom architecture can grow with you. WordPress customizations often become technical debt that eventually requires a rebuild anyway.
The Hybrid Approach
Here's something most agencies won't tell you: it doesn't have to be either/or.
Option 1: Headless WordPress
Use WordPress as a content management system, but build a custom frontend. You get WordPress's excellent editor with custom performance and design.
Option 2: Custom site with blog on WordPress
Build your main site custom, but run your blog on a WordPress subdomain. Best of both worlds for content marketing.
Option 3: Start WordPress, plan for custom
Launch with WordPress to validate your business. Once you know what you actually need, invest in custom development. Just don't over-customize WordPress in the meantime.
Questions to Ask Yourself
Before deciding, honestly answer these:
1. What does my website need to DO?
List the actual functions. "Display information" is simple. "Process payments, manage inventory, send automated emails, integrate with our CRM" is complex.
2. How important is speed and performance?
For some businesses, a 3-second load time is fine. For others, every millisecond of delay costs money.
3. What's my 3-year plan?
If you're testing a business idea, don't over-invest. If you're scaling an established company, think long-term.
4. Who will maintain this?
WordPress needs regular attention. Custom sites need developers for changes. Neither is maintenance-free.
5. What's my actual budget?
Not just the build, but years 1-5 total. Sometimes custom is cheaper long-term.
Red Flags When Choosing
WordPress red flags:
- Agency quotes 100,000+ NOK for WordPress (probably should be custom)
- "We'll build a custom plugin" (custom code on WordPress = worst of both worlds)
- "We need 15 plugins for your requirements" (complexity = fragility)
- Quote seems too cheap (corners will be cut)
- No mention of ongoing maintenance
- "It'll take 6 months" for a simple site (over-engineering)
- Can't show similar work they've built
The Bottom Line
There's no universally "better" option. There's only what's better for your specific situation, budget, and goals.
Go WordPress when:
- Budget under 50,000 NOK
- Standard website needs
- Content/blogging focus
- Need to launch quickly
- Complex functionality needed
- Performance is critical
- Long-term scalability matters
- Budget allows proper investment
Talk to developers who do both WordPress and custom work. Agencies that only do one will obviously recommend their specialty. You want honest advice about your specific situation.
