Built around your business
Make WHMCS work the way you do.
Need something an off-the-shelf addon cannot do? We build custom WHMCS modules, connect external services and automate the jobs that take up your team's time.
Work directly with an experienced UK developer who builds and maintains WHMCS addons. From a small hook to a complete integration, start with what you need to achieve.
Your workflow. Your integration.
- Custom addons & hooks
- API connections & automation
- Client & administrator tools
WHMCS development services
Custom addons & modules
Build a feature around your own processes, with settings and tools inside WHMCS rather than another system to manage.
API integrations
Connect WHMCS to the services you already use. Exchange data, trigger actions and bring useful information into one place.
Hooks & automation
Reduce repetitive work with event-driven actions, scheduled tasks and workflows for your clients and team.
Client & admin tools
Add useful pages, forms, dashboards and reports that fit into the way your clients and administrators use WHMCS.
Addon customisation
Need more from a WHMCSnow addon? Discuss an extension or integration that builds on its existing functionality.
Existing code & upgrades
Have an older custom module or a broken integration? We can review accessible source code and advise on repairs or an update.
Built by the people behind the addons
WHMCSnow has been developing for WHMCS since 2010. Our own products cover SMS, staff knowledge, password policies, file monitoring, surveys and spam protection.
That experience helps us plan custom work around real WHMCS installations and the practical needs of running a hosting business.
- A clear scope before work starts. Agree what the project includes, the price and the expected timescale.
- Designed for your setup. We check your WHMCS version, theme and relevant integrations when planning the work.
- Maintainable integration. We use WHMCS hooks and APIs where appropriate and avoid changes to core files.
- Testing and handover. The quote sets out the testing, installation instructions and support included with your project.
