Vertex is a storefront theme for CS-Cart and Multi-Vendor stores of any sector: electronics, home, beauty, pharmacy, sport, B2B and general stores with large catalogues.
The look is white and precise with ink type and one accent; the colour comes from the merchandising tiles. Header, home and product page layouts are settings, not Block Manager work. Sixteen colour schemes, two dark, follow the Theme Editor colours and each recommends a layout.
One design, sixteen colour schemes
Vertex is one design. Each colour scheme recolours the whole storefront from the Theme Editor colours and brings its recommended header and home layout (Auto). Open any of them in the live demo.

How it works
Install the package in Add-ons: it adds the Vertex theme without touching your storefront. Activate Vertex in Website, Themes and pick a colour scheme. The next admin page adds the Circuit Hall demo catalogue.
Choose header and home layouts in the add-on settings, or leave Auto to follow the scheme. Stage, offers and tiles are banners linked to products and promotions; per-category tiles use the category's Layouts tab.

What you get
Package
kv_theme_vertex-1.0.0.zip: the theme and its wrapper add-on, installed through Add-ons → Manage add-ons. Activate it in Website → Themes, then pick a colour scheme in Website → Themes.
Editions
CS-Cart, CS-Cart Ultimate, Multi-Vendor and Multi-Vendor Ultimate 4.17.2 – 4.21.x, one package. A child theme of Responsive: no core files are changed and add-on templates keep working.
Updates & support
12 months included. Updates keep the theme files you changed; your layouts are never replaced.
License
1 production installation; subdomains, staging, dev and localhost are free. The theme checks its license for your domain once a day from the admin panel. Without a valid license the storefront shows the standard Responsive look instead of the Vertex design; cart, checkout and orders keep working. How licensing works

Is Vertex only for electronics?
No. The demo is a technology store, but the design is sector neutral: white page, ink type and one accent. Schemes such as Fern, Orchid, Copper and Sand suit pharmacy, beauty, home and lifestyle stores.
How is Vertex different from your other themes?
The other themes each have one fixed character. Vertex is the one you configure: header, home and product page layouts are settings, and the merchandising (tiles in the grid, deal of the day, promotions with days left) is managed per category and per post.
Do I need the Block Manager to switch layouts?
No. Header and home layouts are settings. The Block Manager is only needed when you add your own blocks.
Will a colour scheme change my banners?
Banners linked to a product are drawn on the scheme's tile colour, so they change with the scheme. Banners with your own photos keep the photo.
Does it show B2B prices?
It shows quantity discounts on cards and product pages, including customer group prices for signed-in customers.
Is it ready for the 4.21 full page cache?
The theme prints catalogue data and settings only. Countdowns and "days left" are computed in the browser from the promotion end dates.
Does Vertex change my core files?
No. It is a child of Responsive, delivered by an add-on.
Does it work on Multi-Vendor?
Yes. Cards show the seller line and vendor pages use the same cards and Show more button.
A campaign-driven theme: flash bar, bento hero with a live deal tile, flash-deals zone with countdowns, sticker discounts and promo cells inside your product grids.
A Swiss-editorial storefront theme with a shop-window homepage, oversized type and four bold styles, built on Responsive so every add-on keeps working.
