Send a request.
Suppliers come to you.
Pick the materials from the catalog, set your deadline, and get structured offers from verified suppliers - no phone calls, no commissions, no obligations.
A full technical catalog of construction materials
Every product has a technical spec sheet with normalized attributes, so supplier offers are comparable 1:1 - same list, same specifications.
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.
