Quick answer
What is web application development?
Web application development is building custom software that runs in a web browser, such as customer portals, booking systems, internal tools, and dashboards. Unlike a website, which mostly presents information, a web app lets people log in, enter data, and get work done. It's the right choice when off-the-shelf software doesn't fit how your business works.
Los Angeles IT builds custom web applications for Los Angeles businesses from our Century City headquarters, and connects them to the systems you already use. Projects are scoped after a discovery session and billed at $95 per hour or quoted up front.

Custom Web App vs. Off-the-Shelf Software
Off-the-shelf software is often the right answer. Here's when a custom app makes more sense.
| Custom web app | Off-the-shelf software | |
|---|---|---|
| Fit | ✓ Built around your process | You change your process to fit |
| Integrations | ✓ Connects to your systems | Limited to built-in connectors |
| Per-user fees | ✓ None to us | Grow with every user |
| Ownership | ✓ You own the code and data | Vendor controls the roadmap |
| Start-up time | Weeks to months | ✓ Days |
| Best for | Unique workflows, portals, internal tools | Common needs like email or accounting |
How It Works
How We Build Web Applications
Short cycles with working software to review, so there are no surprises at the end.
STEP 01
Discovery
We map your process, users, data, and the systems the app must connect to, then define a first version.
STEP 02
Prototype
We design screens and a clickable prototype so your team can react before code is written.
STEP 03
Build in sprints
We build and demo working features every week or two, adjusting as we learn.
STEP 04
Launch & support
We deploy, train your team, and keep the app updated, secure, and improving.
Pricing
How Much Does a Custom Web App Cost?
Web application cost depends on the number of screens and user roles, the data involved, integrations with other systems, and security requirements. We start with a discovery session, define a focused first version, and quote it, or bill at $95 per hour for smaller or open-ended work.
Starting small and adding features in later phases keeps cost and risk down and gets the app into your team's hands sooner.
What affects the price
- Screens and user roles
- Integrations with other systems
- Data migration from old tools
- Security and compliance needs
- Hosting and ongoing support

Examples
What Businesses Build With Us
Common projects include client portals for document upload and status updates, quote and job tracking tools for service companies, intake and scheduling forms that feed a database instead of an inbox, inventory and asset tracking, and replacements for aging Access databases or shared spreadsheets.
Many projects start as a workflow automation and grow into an app when the process needs its own screens.
Typical projects
- Client portals
- Quote and job tracking
- Intake and scheduling
- Inventory and assets
- Spreadsheet replacements
Security
Secure by Design
Business apps hold customer and company data, so we build security in: single sign-on with Microsoft 365 where possible, role-based access, encrypted connections, audit logs, and backups. Apps that handle health or financial data are designed with your compliance requirements in mind.
Security built in
- Microsoft 365 sign-in
- Role-based access
- Encryption in transit and at rest
- Audit logs and backups
