Start by choosing a base theme that closely aligns with your vision. WHMCS comes with built-in themes like "Six" and "Twenty-One," which you can customize.
Before making any changes, ensure you have a backup of your WHMCS files. This helps you revert if something goes wrong.
Duplicate the current theme folder (e.g., /templates/six) and rename it. Update the templateinfo.php file in your new theme folder with unique details.
You can rearrange sections, add new blocks of content, or remove unnecessary elements by editing these .tpl files.
If you want to add unique pages, copy the clientarea.tpl and rename it, then create a corresponding page in your php files.
WHMCS themes are responsive by default, so check how your customizations look on various devices.
Create a unique experience that sets your brand apart!
