## In short
Custom software development is the design and build of software made specifically for one organisation’s workflows, instead of adapting a generic off-the-shelf product. LOLCorp, a London agency, builds it to a fixed scope and price, typically delivers a first release in about 4–6 weeks, and you own all the code.

## Software development services for UK businesses
LOLCorp is a London software development company and software development agency serving clients across the UK. Our software development services cover business software development, custom application development and enterprise software development, from first workshop to production support.

As a custom software developer and bespoke software development company, we work with founders, operations teams and IT leaders who have outgrown spreadsheets or off-the-shelf tools. If you are looking for custom software development in the UK or a custom software developer UK businesses can meet in person, we are based in Covent Garden. We are also a bespoke software development company UK clients choose for fixed prices and full ownership.

Many projects start as custom business software that automates a process, and grow into a platform. We also provide business process automation software, a dedicated software development team for ongoing roadmaps, and outsourced software development for defined projects.

## FAQ
### How much does custom software development cost?
Cost depends on scope: features, users, integrations and timeline. We work to a fixed price agreed after a short discovery call, and the instant quote tool gives you an indicative range in about a minute.

### How long does custom software take to build?
Typically 4–6 weeks for a focused first release. Larger platforms are phased so you are live early and keep adding capability.

### Who owns the source code?
You do. Code, designs, infrastructure configuration and IP transfer to you at the end of the project.

### Do you work with companies outside London?
Yes. We are based in London and work with clients across the UK and internationally, fully remote or on site.
