Are you a supplier? See how it worksA complete technical catalog of construction materials
Every product has a normalized spec sheet, so offers compare 1:1. Categories open one by one as vendors list their stock.
From a materials list to comparable offers
Build your list and send the request
Pick the exact products from the catalog, set the delivery zone and deadline - between 1 and 7 business days. Publishing is free, always.
Eligible suppliers submit offers
The request automatically reaches verified suppliers in your categories and counties. They send structured offers, on your product list, until the deadline.
Above the platform's value threshold, launch a 48h sealed-bid auction instead of the normal flow - entirely optional.
Compare, choose, connect
See the offers side by side. Choose your supplier, and after the GDPR double opt-in you both receive each other's contact details and finalize directly.
