Website or web app: which one does your business need?
Websites share information, web apps let people get work done. Here's how to tell which you need, what each costs in time and effort, and when to build both.

"We need a website" is one of the most common requests we hear. Sometimes that's exactly right. Other times, what the business really needs is a web app, and building the wrong one wastes months.
The difference isn't about how it looks. It's about what people do with it.
The short answer
A website mainly shares information. People read about your business, see your work and get in touch.
A web app is software people log in to and use. They book, order, track, upload, approve or manage something, and the app remembers their data.
A simple test: if most visitors need their own account to get value from it, you're probably building a web app.
Signs you need a website
A website is usually the right choice when:
Your main goal is to explain what you do and get enquiries
Visitors don't need to log in
The content changes occasionally, like new services, case studies or blog posts
You want to rank on Google for searches your customers make
Most company sites, landing pages, portfolios and brochure-style sites fall here. They're quicker to build, easier to maintain and cheaper to run.
Signs you need a web app
A web app makes sense when:
Customers or staff need their own accounts and data
People complete tasks, like booking slots, placing orders or approving requests
You're replacing spreadsheets, paper or WhatsApp threads with one system
Different people need different permissions, such as admins, staff and customers
You need to connect to payments, CRM, accounting or other tools
Customer portals, booking systems, admin dashboards, internal tools and SaaS products are all web apps.
How they differ in practice
Time to build
A small business website often takes a few weeks. A web app usually takes a few months, because there's more to design, build and test: logins, data, permissions and edge cases.
Cost to run
A website can often run on simple hosting. A web app needs a database, more careful hosting, backups and monitoring, so running costs are higher.
Ongoing work
Websites mostly need content updates and security patches. Web apps need regular updates, bug fixes and new features as people use them, so plan for ongoing support from the start.
When you need both
Many businesses end up with both, and that's normal. A clinic might have a website that explains services and ranks on Google, plus a booking web app where patients choose slots and pay. A software company might have a marketing website and a separate product app.
They can share a domain and design, so customers experience them as one brand, while each is built for its own job.
Start with the smallest useful version
If you're unsure, start by writing down the three most important things people need to do. If all three are "learn about us" and "contact us", build a website. If any of them is "log in and do something", you're looking at a web app, and it's worth planning a focused first version rather than every feature at once.
Not sure which one fits your plans? Tell us what you want customers to be able to do, and we'll recommend the simplest option that works, along with an honest estimate of time and cost.
