Web app development for products that need to move fast

SaaS platforms, admin dashboards, customer portals, and internal tools - scoped in discovery, shipped in two-week sprints, handed over with tests and docs.

Web apps are where most businesses run: billing, onboarding, operations, and the product itself. Impactful Tech builds custom web applications on modern stacks (Laravel, React, Livewire, and integrated AI services) with the same sprint model we use for mobile - so you see working software every two weeks, not a big-bang launch months later.

Web apps we specialise in

We focus on software that drives revenue or removes operational drag: multi-tenant SaaS, client portals, admin dashboards, workflow tools, and progressive web apps that behave like native on mobile browsers.

  • B2B SaaS and subscription products
  • Customer and partner portals
  • Internal ops and workflow tools
  • Progressive web apps (PWAs)

Modern stack, maintainable code

We choose boring, proven technology where it matters: relational data, clear API boundaries, automated tests, and CI/CD from sprint one. That keeps your app fast to extend when requirements change - which they always do.

  • Laravel and PHP for robust backends
  • React or Livewire for interactive UIs
  • Postgres, Redis, and queue-backed jobs
  • Hosted on AWS, DigitalOcean, or your cloud

Delivery you can plan around

Discovery produces wireframes, user stories, and a technical spec your stakeholders can approve. Each sprint ends with a demo, release notes, and deployed code. You are never guessing what your budget bought.

  • Fixed sprint pricing after discovery
  • Automated tests on critical paths
  • Security and performance baselines
  • Documentation and handover for your team

Frequently asked questions

Web app vs website - what is the difference?

A marketing website presents information. A web app lets users log in, change data, run workflows, and complete tasks. If your product needs accounts, permissions, or dynamic behaviour, you need a web app - not a CMS site with plugins bolted on.

How much does custom web app development cost?

Discovery starts around £1,500. A typical MVP is four development sprints from £18,000 on top of discovery. Modernisation of legacy web apps often runs three sprints from £13,500. Exact scope is confirmed in the roadmap sprint.

Do you rebuild legacy web apps or extend them?

Both. We audit what to keep, wrap, or replace incrementally so the business keeps running. Strangler patterns and automated regression tests let you modernise without a risky big-bang rewrite.

Can you integrate payments, auth, and third-party APIs?

Yes - Stripe, OAuth, CRMs, ERPs, webhooks, and custom APIs are standard in our projects. Integrations are scoped in discovery so there are no surprise dependencies mid-build.
