You might hear terms like "web app", "portal", "dashboard", or "platform" thrown around. They all mean roughly the same thing: software that runs in a web browser and lets users do something - not just read information.
Gmail is a web app. Online banking is a web app. Xero is a web app. If you can log in and manage data, it's probably a web app.
This guide explains when your business might need a custom web app, what it costs, and how to think about building one.
Website vs Web App - What's the Difference?
The line is blurry, but here's a simple way to think about it:
Website
- Primarily displays information
- Same content for everyone
- Visitors read, watch, browse
- Simple contact forms
- No login required
- Example: Your company homepage
Web App
- Users interact and do things
- Personalised for each user
- Users create, manage, process data
- Complex functionality
- Login and user accounts
- Example: Customer portal, dashboard
Most businesses have both: a marketing website that anyone can visit, and a web app (portal/dashboard) for customers or staff who log in.
Do You Need a Web App?
A Web App Makes Sense When...
- Customers need self-service - checking orders, managing accounts, accessing documents without calling you
- Staff need a central system - a dashboard to manage operations, view reports, handle tasks
- You're replacing spreadsheets - data that's outgrown Excel and needs proper structure
- Multiple people need access - different users with different permission levels
- You need it accessible anywhere - from office, home, or the field, on any device
- You want to automate processes - workflows, approvals, notifications, calculations
You Might Not Need a Web App If...
- Off-the-shelf tools handle it (Trello, Notion, Airtable, etc.)
- It's really just a contact form or simple calculator
- Only one or two people will use it
- A spreadsheet genuinely works fine for your scale
Common Types of Web Apps
Here's what we build most often for Perth businesses:
Customer Portals
Customers log in to view orders, invoices, documents, support tickets, or account information. Reduces "where's my order?" calls.
Staff Dashboards
Internal tools for managing operations - job tracking, inventory, reporting, team management. The stuff you used to do in spreadsheets.
Booking & Scheduling Systems
Customers book appointments, classes, or services online. Staff manage calendars and availability.
Quote/Order Management
Sales team generates quotes, tracks orders, manages pipeline. Often integrated with accounting.
Reporting & BI Dashboards
Real-time business intelligence - pulling data from multiple sources into visual dashboards.
What Does a Web App Cost?
Web apps vary widely in cost depending on complexity:
Start with MVP: Don't build everything at once. Start with core functionality (3-4 months, $30-50K) and expand based on real usage.
Web App vs Mobile App - Which Do You Need?
This is a common question. Here's how to think about it:
Choose Web App When...
- Users work on desktop/laptop
- You need quick, easy updates
- No App Store approval needed
- Complex data entry involved
- Budget is limited (one codebase)
- Users don't want to install anything
Choose Mobile App When...
- Offline functionality needed
- Push notifications are critical
- Camera, GPS, sensors required
- Speed/performance is crucial
- App Store presence matters
- Field workers need quick access
The hybrid answer: Many businesses have a web app for staff/back-office and a mobile app for customers or field workers. Modern web apps can also be "installed" on phones as Progressive Web Apps (PWAs), giving you some mobile benefits without building a separate app.
How Long Does Development Take?
Discovery & UX Design
2-4 weeks. Understanding requirements, mapping user flows, wireframing the interface.
Visual Design
2-3 weeks. Designing the look and feel - colours, layout, visual style that matches your brand.
Development
6-12 weeks. Building the application, setting up the database, creating the user interface.
Testing & Launch
2-3 weeks. Quality assurance, user acceptance testing, deployment to production.
Typical total: 3-5 months for a focused MVP, 5-9 months for a full-featured web app.
Common Mistakes to Avoid
What Goes Wrong
- Designing for yourself, not users - involve actual users in design. What makes sense to you might confuse them.
- Too many features at launch - start simple and add based on real feedback. Feature bloat is expensive.
- Ignoring mobile - even if it's a "desktop app", people will access it on their phones. Design responsive from the start.
- Poor security planning - user authentication, data encryption, and access controls aren't optional extras.
- No analytics - if you don't track how people use it, you can't improve it. Build in analytics from day one.
- Underestimating content - someone needs to write the help text, error messages, and documentation.
