About this gig
Secure, Tested, and Reliable WHMCS Development
Need a WHMCS developer who understands your business, not just the code?
I build secure, thoroughly tested custom WHMCS solutions that automate workflows, integrate third-party services, improve customer experience, and help your hosting or SaaS business scale.
Services include:
- Custom WHMCS addon and provisioning modules
- API integrations and data synchronization
- Payment gateway and registrar integrations
- Hooks, billing automation, reports, and custom workflows
- Module customization, troubleshooting, and compatibility updates
Every solution is built around your workflow. I define the scope, use secure coding practices, test critical scenarios, and deliver reliable, maintainable code with documentation where agreed.
Existing modules can be enhanced, extended, or modernized without unnecessary core-file modifications whenever possible.
Please contact me before ordering with your workflow, WHMCS version, and requirements. I'll recommend the best package.

FAQ
Can you customize an existing WHMCS module?
Yes. I can review, modify, and extend an existing WHMCS module when its source code is available and the license permits modification. I will preserve the existing functionality and make only the required changes.
Can you integrate a third-party API with WHMCS?
Yes. I can connect WHMCS with hosting panels, cloud platforms, CRMs, accounting software, domain registrars, notification services, and other systems that provide usable API documentation.
Do you develop custom WHMCS payment gateways?
Yes. I can develop or customize payment gateway modules, including payment processing, callbacks, webhooks, transaction verification, refunds, recurring billing, and invoice status updates.
Can you automate a manual WHMCS workflow?
Yes. I can automate repetitive tasks involving billing, provisioning, account suspension, notifications, support tickets, invoices, renewals, data synchronization, and custom business rules.
Will my existing WHMCS installation remain safe?
I prioritize production safety and recommend using a staging environment and current backups. I avoid unnecessary core-file modifications and test the agreed workflow before production deployment.
Will the module work after future WHMCS updates?
The solution will be developed and tested for the agreed WHMCS, PHP, and third-party API versions. Future platform or API changes may require a compatibility update, which can be provided separately.
Can you troubleshoot a broken WHMCS module or hook?
Yes. I can investigate module errors, hook failures, API problems, configuration issues, database errors, permission problems, and compatibility conflicts. Please provide logs, screenshots, and steps to reproduce the issue.
Can you work with my existing developer or technical team?
Yes. I can work with your developer, repository, staging environment, coding standards, and deployment process. Clear requirements and acceptance criteria will help keep the project efficient.
What information do you need before starting?
Please provide your business workflow, desired outcome, WHMCS and PHP versions, current modules, API documentation, screenshots, logs, test credentials, hosting environment, deadline, and acceptance criteria.
Do you provide support after delivery?
Yes. Each package includes a defined support period for defects within the agreed project scope. New features, platform upgrades, API changes, or additional workflows will require a separate quote.
