Web Development
Need functionality that WHMCS doesn't offer out of the box? I develop robust, secure Custom Modules that integrate 3rd party APIs, automate complex workflows, and extend your billing system.
If it has an API, I can integrate it into WHMCS
Automate product activation for any service. Create, Suspend, Unsuspend, Terminate, upgrade/downgrade resources automatically via API.
Add completely new pages and features to the WHMCS admin or client area. Build dashboads, reporting tools, or custom client management interfaces.
Sell domains from any registry or accredited registrar. Automate registration, transfer, renewal, and DNS management.
Accept payments from local banks, mobile wallets, or crypto. Secure integration supporting one-time, subscriptions, and tokenized payments.
How I ensure quality and security in every line of code
Reviewing API documentation and defining the scope of automation.
Coding the module adhering to WHMCS best practices and PHP standards.
Rigorous testing of success/fail scenarios, error handling, and logging.
Installation on your production environment and final verification.
Send me the API documentation or your idea, and I'll tell you if it can be built (Spoiler: It usually can).
Common questions about WHMCS module development
Development time varies by complexity. A simple addon module takes 3-5 days, while a complex provisioning module with API integration can take 1-3 weeks. I provide accurate timelines after reviewing your requirements.
Yes, you receive full, unencrypted source code with detailed documentation. This ensures you're not locked into any vendor and can maintain or modify the module in the future.
I build modules following WHMCS best practices and official APIs, ensuring forward compatibility. I avoid deprecated methods and core file modifications. Most modules work across multiple WHMCS versions without changes.
I offer a 30-day revision period for bug fixes and minor adjustments. For new features or major changes, I provide priority support at competitive rates. Many clients have ongoing maintenance agreements.
