WHMCS Client Area UI/UX Customization to Match Existing WordPress Brand Design

My WordPress site already has a well-defined visual identity; I will supply the exact palette, typography choices, and spacing rules. Your job is to bring that same look and feel into the WHMCS client area so the transition from site to portal feels seamless.

Scope of UI/UX work
• Re-shape the dashboard layout so key data hits the eye instantly.
• Restyle all forms and input fields to echo the WordPress component library—consistent corner radii, button states, error messaging, and focus outlines.
• Rework navigation and menus to mirror my site’s hierarchy while remaining fully WHMCS-compliant.

Priority screens
Account overview, support tickets, billing & invoices, plus the cart, checkout, and individual service pages all need the new treatment. Every template should be responsive, cross-browser tested, and light-weight so page speed is not sacrificed.

Technical notes
You may work directly with WHMCS Smarty templates, custom hooks, and CSS/SCSS—no core file edits, please. JavaScript enhancements are welcome if kept modular. The final package should drop into the /templates directory and include a brief install guide so I can update safely on future WHMCS releases.

Deliverables
1. Complete set of modified WHMCS template files
2. Compiled and source CSS/SCSS matching my brand kit
3. Any custom JS, hook files, or assets used
4. Installation & update instructions

I’m ready to hand over the style guide and staging access as soon as we agree on the workflow and timeline.
