A web application is more than a website — it's the software your business, your team, or your customers rely on every day. These are the eight shapes it usually takes.
Purpose-built software designed around your exact workflows and business rules, not adapted from a generic template.
Large-scale applications engineered for multiple departments, complex permissions, and high concurrency.
Secure portals for customers, vendors, or partners to interact directly with your business online.
Multi-tenant, subscription-ready platforms built to onboard customers at scale from day one.
Installable, offline-capable web apps that feel native, without app-store approval delays.
Custom CRM and ERP systems tailored to your sales pipeline, operations, and reporting needs.
Applications architected natively for AWS, Azure, or Google Cloud from the very first sprint.
Applications built around clean, well-documented APIs that connect to the systems you already use.
Every project runs on the same standards, whether you're a startup shipping your first product or an enterprise modernising a critical system.
Senior engineers who've shipped production web applications, not learned on your project.
Sprint-based delivery with regular demos, so you see progress every two weeks.
Systems designed to handle tomorrow's traffic, not just launch day.
Security reviewed at every stage of development, not bolted on before release.
Applications built to take full advantage of modern cloud infrastructure.
Every application built with integration and future extensibility in mind.
Applications tuned for speed at both the frontend and backend layer.
A single point of contact who owns your project from kickoff to launch.
Maintenance and enhancement plans that keep your application current after go-live.

Applications designed from the ground up around your specific business processes rather than adapted from a generic template.

Frontend, backend, database, cloud, DevOps and API layers are all delivered by one team — no handoffs between vendors.

Most custom web applications take between 8 and 20 weeks. An internal portal or business tool typically lands in 8–12 weeks, a full custom application in 12–16, and an enterprise or SaaS platform in 16–20+. Cost is scoped per project after discovery, and you receive a detailed written estimate before any build work starts.
| Application type | Typical timeline | What it usually includes | Best for |
|---|---|---|---|
| Business portal or internal tool | 8–12 weeks | Auth and roles, core workflows, reporting, one or two integrations | Replacing spreadsheets or a manual process with real software |
| Custom web application | 12–16 weeks | Bespoke business logic, third-party integrations, admin tooling, automated tests | Software built around workflows no off-the-shelf product handles |
| Enterprise or SaaS platform | 16–20+ weeks | Multi-tenancy, subscription billing, SSO, granular permissions, cloud-native scaling | Multi-department rollouts and subscription products onboarding at scale |
| Legacy modernisation | Scoped per module | Phased migration, data transfer, parity testing, staged cutover | Replatforming a system already in production without disrupting operations |
