Web Application Development
Custom Web Applications Built Around Your Business
When off-the-shelf software can't match the way your business operates, a custom web application closes the gap. Block30 Development designs and builds web applications — from SaaS platforms and customer portals to internal tools and dashboards — that automate workflows, centralize data, and scale with your organization.
We approach web application development as software engineering, not page building: thoughtful architecture, clean data models, tested code, and interfaces your team can actually use.

Problems Custom Web Applications Solve
Critical work lives in spreadsheets and inboxes
When key processes depend on manual tracking, errors multiply and nothing scales. A purpose-built application turns ad-hoc work into a reliable system.
Off-the-shelf software almost fits
Paying for tools that cover 70% of your workflow — and working around the other 30% — costs more over time than building the right system.
Data is scattered across disconnected tools
A custom application can unify data from multiple systems into one source of truth with reporting your team actually uses.
Customers need self-service access
Portals let customers check status, manage accounts, and submit requests themselves — reducing support load while improving their experience.

Frequently Asked Questions
Common questions about our web application development services.
What's the difference between a website and a web application?
A website primarily presents content; a web application performs work — user accounts, data processing, workflows, dashboards, transactions. If your project involves users doing things rather than just reading things, it's an application.
How much does a custom web application cost?
Scope drives cost: features, integrations, user roles, and data complexity. We typically recommend starting with a well-defined first release, then expanding based on real usage. You'll get a detailed estimate after an initial scoping conversation.
How long does web application development take?
A focused MVP can often be delivered in a few months; larger platforms are phased over a longer roadmap. We work in iterations so you can start using and testing core functionality early.
Who owns the code and the data?
You do. The application, its source code, and its data belong to your business. We build to standard, documented practices so you're never locked in.
Can you integrate with our existing software?
Yes — CRMs, ERPs, payment processors, email platforms, and internal systems. Where APIs exist we use them; where they don't, we can build the integration layer.
Do you provide ongoing maintenance?
Yes. We offer ongoing support covering updates, security patches, monitoring, and feature development so the application keeps improving after launch.
