[Service · Web / SaaS / Customer portals]
Web application development
We build SaaS products, customer portals, dashboards, and operational web software with clear UX, dependable architecture, and transparent delivery stages.
A web application is a working system, not a collection of pages
We design around user actions: authentication, roles, recurring workflows, data, notifications, payments, documents, and integrations. Before engineering begins, we model release priorities and the states teams often miss—errors, empty views, access limits, and unreliable external services.
Web application cost depends on workflow complexity, data models, permissions, integrations, and scale requirements rather than screen count alone. Our estimate is tied to a defined scope and explicit assumptions instead of a generic promise without product context.
What we build
- 01
SaaS and customer portals
Registration, subscriptions, roles, profiles, workspaces, billing, and account administration.
- 02
Operational web systems
Dashboards, records, planning, document workflows, and tools for internal teams.
- 03
APIs and integrations
Connections to CRM, ERP, payment services, maps, analytics, and industry data sources.
- 04
Production launch
Critical-path QA, environments, observability, and a safe process for continued releases.
From estimate to release
- 01
Context and requirements
Define users, workflows, data, integrations, and completion criteria.
- 02
Prototype and architecture
Validate experience and technical decisions before full implementation.
- 03
Iterative engineering
Build vertical product slices so working software is reviewed throughout delivery.
- 04
QA and launch
Verify permissions, errors, responsive behaviour, performance, and infrastructure readiness.
Web application development questions
01How much does a web application cost?+
threeit’s baseline estimate begins at $3,299. The final cost depends on workflows, roles, integrations, data, and launch requirements; we document assumptions and stages after an initial discussion.
02What affects web app pricing?+
The main drivers are workflow complexity, permissions, data models, third-party integrations, performance, security, and administration requirements.
03Can the product launch in phases?+
Yes. We define a useful first release, protect the architecture for growth, and move secondary capabilities into an evidence-based roadmap.
