Custom web application development

Web Application Development Services for Portals, Dashboards & Internal Tools.

Q: What types of web applications does QalbIT typically build?

We usually build customer and partner portals, admin panels, internal workflow tools, reporting dashboards and line-of-business applications that replace spreadsheets or legacy systems. Many of these web applications are part of larger platforms, SaaS products or digital transformation initiatives.

Q: How much does it cost to develop a custom web application?

Cost depends on scope: number of user types, screens, integrations, workflows and non-functional requirements such as security and availability. After a short discovery phase, we usually provide a scoped estimate that clearly separates essential features for the first release from nice-to-have items that can be phased in later.

Q: How long does a custom web application development project usually take?

Smaller, focused web applications or modules can often be delivered in a few weeks, while more complex, multi-module systems may run over several months. Timelines depend on how clearly requirements are defined, how many integrations are needed and how quickly feedback is provided during the project.

Q: Which technologies do you use for web application development?

For backends we typically use Laravel (PHP) or NestJS (Node.js), and for frontends we often use Next.js (React) or Blade with Tailwind CSS. We pair these with relational databases such as MySQL or PostgreSQL, Redis for caching and queues, and cloud providers like AWS or DigitalOcean for hosting.

Q: Can you modernise or rebuild an existing legacy web application?

Yes. A large part of our work involves modernising legacy web applications that are slow, difficult to maintain or locked into outdated frameworks. We usually audit the current system, identify what works and what does not, then propose a phased rebuild so you can move to a modern stack without disrupting day-to-day operations.

Q: Do you provide ongoing support and maintenance for web applications?

We can provide structured support and maintenance through retainers or AMCs, covering bug fixes, minor enhancements, security updates and infrastructure checks. For some clients we also act as a long-term product and engineering partner for continuous improvements.

Q: How do you ensure security and performance for custom web applications?

We follow best practices such as role-based access control, input validation, secure authentication, encrypted communication (HTTPS) and least-privilege access to data. On the performance side, we use optimised queries, caching, queues and sensible infrastructure sizing, and we set up monitoring so issues can be detected and resolved early.

Q: Can you integrate the web application with our existing systems and third-party tools?

Yes. Most web applications we build rely on secure integrations with CRMs, ERPs, payment gateways, ticketing systems or internal APIs. We design clean integration layers, document the APIs and ensure that failures are handled gracefully so your users are not blocked by external issues.

QalbIT designs and builds custom web applications that sit at the heart of your business – from customer-facing portals and self-service dashboards to internal tools and workflow automation. We focus on web application development that reduces manual work, centralises data and gives teams faster, more reliable ways to operate.

Web application development overview

Web application development services for modern, workflow-driven businesses

We help teams replace spreadsheets and fragile legacy tools with secure, scalable web applications. Our web application development services cover everything from discovery and UX to architecture, delivery and long-term support.

When custom web application development with QalbIT makes sense

You have manual or spreadsheet-based processes that need a centralised web application.
You want a secure web portal for customers, partners or vendors instead of sending endless emails.
Your existing web app is slow, fragile or difficult to maintain and needs a thoughtful rebuild.
You need a web-based dashboard that pulls data from multiple systems into one place.
You prefer a senior, founder-led team that understands both product and engineering trade-offs.

Outcomes we usually target with web applications

Clear, reliable workflows that reduce manual work and back-and-forth.
A single source of truth for data instead of scattered spreadsheets and tools.
Faster response times for customers, partners and internal teams.
A web application architecture that is easier to extend, integrate and maintain.
Predictable releases and support so your web app remains stable in production.

For most web application development projects, we start with a short discovery phase to understand processes, data flows and constraints before proposing an implementation plan.

What we build as web applications

Web application development capabilities across portals, tools and dashboards

From customer portals to internal admin tools, we design and build custom web applications that match how your business actually works.

Workflow and process automation

Automation

Custom web apps that automate approvals, notifications and hand-offs between teams, reducing manual follow-ups.

Reporting and analytics dashboards

Analytics

Role-based web dashboards that bring together KPIs, reports and logs from multiple systems into a single view.

Integrations and API-driven web apps

Integrations

Web applications that talk to your CRM, ERP, payment gateways or third-party APIs using secure, well-documented integrations.

How web app projects work with QalbIT

A practical web application development process from idea to stable release

We keep the process structured but lightweight, so your web application can move from concept to production without unnecessary complexity.

01

Discovery and requirements

1–2 weeks

Understand your workflows, users, data sources and constraints, then define clear objectives for the web application.

Key outcome: Documented requirements, user types, core modules and a realistic first release scope.
02

UX, architecture and planning

1–3 weeks

Design key user journeys, information architecture and a technical approach using suitable web application frameworks.

Key outcome: Wireframes, architecture decisions and a plan that balances speed and maintainability.
03

Implementation and integrations

4–10+ weeks (scope-dependent)

Build the web application in small increments, integrate required APIs and ensure access control and data validation are solid.

Key outcome: A working web application ready for pilot users or staging review.
04

Testing, launch and handover

2–4 weeks

Perform QA, security checks and performance tuning, then launch the app and hand over documentation and training.

What is custom web application development and how is it different from a normal website?

A normal website is usually content-focused – pages, blogs and marketing information. Custom web application development is about building interactive, login-based systems where users perform tasks: managing data, submitting requests, viewing reports or collaborating with others. We design and implement the business logic, permissions, workflows and integrations behind those interactions.
