# Custom Web App Development

Source: https://brainglow.io/services/development-services/web-applications

Build custom web applications with BrainGlow: customer portals, internal tools and operational platforms with permissions, integrations and a clear launch plan.

## Overview

When spreadsheets and disconnected tools become a bottleneck, a custom web application can give your team one place to do the work. We build around the users, rules and data that make your operation different.

Typical projects include client portals, approval workflows, internal operations tools and booking platforms. We start with a narrow workflow and build a maintainable foundation before expanding.

## Use cases

- Customer or partner portals
- Internal operations and approval tools
- Custom booking or service-delivery platforms

## Who this is for

- Customer or partner portals
- Internal operations and approval tools
- Custom booking or service-delivery platforms

## Deliverables

- Workflow discovery, user roles and acceptance criteria
- Responsive application UI and reusable components
- Authentication, authorization and database models
- Business rules, API integrations and data validation
- Behavior tests, error handling and operational monitoring
- Production deployment and technical documentation

## Process

- Map users, permissions, data and the core workflow
- Prototype priority screens and agree acceptance criteria
- Build the application in reviewable increments
- Test permissions and recovery, deploy and hand over

## Scope and commercial model

Estimated after discovery

Discovery followed by milestone-based implementation

## Acceptance criteria

- Delivery: Agreed acceptance criteria
- Measurement: Baseline and project goals
- Handoff: Documented ownership

Acceptance and measurement are agreed during discovery; outcomes are not guaranteed.

## Questions and answers

### When is a custom app better than an off-the-shelf tool?

A custom build is worth considering when a critical workflow cannot fit existing tools without costly workarounds. Discovery compares customization, integration and custom development before committing.

### Can the app connect to our existing systems?

Usually, if the systems expose suitable APIs or supported connectors. We check access, rate limits, data ownership and synchronization behavior during discovery.

### Who owns the code after delivery?

Ownership, repository access, licensing and handoff are documented in the project agreement. We discuss these before work begins rather than leaving them until launch.
