Custom Salesforce Development by Certified UK Developers
Fulminous Software is a UK Salesforce development company building the custom features, apps and integrations that off-the-shelf configuration can't. Apex, Lightning Web Components, integrations and CRM builds — delivered by certified developers, in GBP, with UK GDPR built in.
Salesforce Development Company in the UK
Salesforce does a lot out of the box — but the moment your processes are unique, your integrations are complex, or your users need something the standard tools can't deliver, you need development. That's where a specialist Salesforce development team turns a generic CRM into a platform built around your business.
As a UK Salesforce development company and agency, Fulminous Software builds custom solutions on the Salesforce platform — Apex code, Lightning Web Components, custom objects and automation, API integrations, and full custom apps. We favour configuration where it's the right tool and use code where it genuinely adds value, so you get robust, maintainable solutions rather than unnecessary complexity.
Certified developers, transparent GBP pricing, full ownership of your code, and support that continues after go-live.

Development vs Configuration — What You Actually Need
Configuration uses Salesforce's built-in point-and-click tools — flows, layouts, settings. It's fast and low-risk, and it's the right choice for a lot of requirements. Development adds custom code — Apex, Lightning Web Components, integrations — for the things configuration can't do.
The best solutions use both: configuration wherever it works, code where it genuinely adds value. We won't over-engineer with code you don't need — but when your requirement demands real development, you get developers who do it properly and maintainably.
How we decide
- Configuration: fast, low-risk, no code — used first
- Development: custom code for complex or unique needs
- We favour config, and code only where it adds value
- Result: robust, maintainable, not over-engineered
