## In short
Web application development is building software that runs in the browser, such as portals, dashboards and SaaS products. LOLCorp builds secure, scalable custom web applications to a fixed scope and price, with full code ownership.

## What we mean by custom web application development
A web application is software people use in the browser to get work done: a customer portal, a booking system, an operations dashboard, a marketplace or a full SaaS product. Custom web application development means building it around your workflow, rules and data, rather than adapting someone else’s product.

We build business web applications and enterprise web applications with the controls larger organisations expect: single sign-on, granular permissions, audit trails, and data stored and processed under UK GDPR. We also build dashboards that turn scattered data into live reporting, and take a product mindset to software product development and product engineering, from first release to a roadmap.

If you are launching a new product, start with our [MVP development](https://lolcorp.co.uk/services/mvp-development/) or [SaaS development](https://lolcorp.co.uk/services/saas-development/) service. For connecting systems, see [API development and integration](https://lolcorp.co.uk/services/api-development-integration/). Our [complete guide to custom software development](https://lolcorp.co.uk/guides/custom-software-development-guide/) explains the whole process.
