Nexum WHMCS Client Area theme

Nexum WHMCS Client Area theme

Developed By Provonic

Compatible with WHMCS v9.0

Nexum is a WHMCS client area theme, a WHMCS order form template and an addon module, sold and installed together as one package by Provonic. It is a modern WHMCS theme and a responsive WHMCS template in one: the client area theme for WHMCS, the order form theme and the theme manager that controls both, so the whole client area and order form can be redesigned from the WHMCS admin area with no template editing.

The addon is a theme customizer and theme customiser for WHMCS: colour scheme and color scheme presets, custom palettes, a dark palette generated in one step, typography settings with self-hosted fonts or Google Fonts, top navigation or a left sidebar, a navigation menu builder, a homepage builder, a domain transfer page editor, dashboard widgets, a promo banner slider, footer columns, legal pages, an SEO manager and a custom CSS editor. Every change is applied to the client area straight away, without editing templates, and a settings snapshot is taken first so any change can be rolled back.

For your clients it is a customizable client area with light and dark mode: a client area dark mode they can switch on, a dashboard with drag-and-drop dashboard panels, sign-in and registration pages with a side panel, services and invoices pages with summary tiles, and a step-by-step whmcs order form from the product list and domain search through the checkout page. Whether you are looking for a whmcs dark theme, a dark mode theme, a client portal theme, a customer portal theme or a whmcs skin, Nexum covers it.

We’d been putting off redesigning our WHMCS client area because we didn’t want to mess with template files or hire a developer. Nexum made it much easier to customize colours, menus, and layouts. Dark mode and the drag-and-drop dashboard are great additions, and the checkout experience feels smoother. There was a small learning curve and one styling issue, but support fixed it quickly. Overall, we’re happy with it!
