B2B marketplace design · 2026

STR

A marketplace for heavy equipment spare parts: buyers look up a part by its number, or a whole list at once, and get a quote from sellers. We designed every page for desktop, tablet and phone and built the design into the site.

Task

We have been building this marketplace on CS-Cart Multi-Vendor since 2024: sellers upload their catalogs, and buyers search by part number and request quotes. In 2025 we installed the UniTheme2 theme and restyled it in the company colors and logo.

In spring 2026 the client ordered a design for every page on desktop, tablet and phone. The brief: yellow with dark gray, a banner carousel on the home page and a header like the big marketplaces have, with a large search bar and a catalog button.

Before and after

The first screen: the company site at ctp.com.ru in May 2024 (Wayback Machine snapshot) and the marketplace home page, both 1280 pixels wide. Drag the divider.

Home page

  • The first screen is a carousel of heavy equipment banners with a part number search and a Bulk search button.
  • The header has the city, a Catalog button, phone, account and cart, with Become a supplier and Delivery and payment links above.
  • Four benefits with icons: guaranteed compatibility, fast delivery, help with parts selection and the best prices.
  • Equipment brand logos as tiles and an All brands button.
  • Best deals of the day: cards with the part number, supplier, price and delivery time.

Bulk search

  • Results for a list of part numbers: each line shows the alternative number, manufacturer, brand, available quantity, price and delivery time.
  • Supplier offers open under each part number, with a Total field above them, so the quantity can be split across several suppliers.
  • The selection rule is fastest delivery or lowest price, with totals for products, delivery and VAT at the bottom.
  • At the top: checkout, the quote as a PDF or by email, adding by part number and searching for another brand.
  • In summer 2026 the quantity selection in search results was rebuilt to match this mockup.

Search and quotes

Search by a list of part numbers or a template file, a window that redistributes quantities when the selection rule changes, and quote requests in the account, where selected quotes go to the cart in one click.
